Filename: draft-ietf-6lowpan-nd Revision: 05 Title: 6LoWPAN Neighbor Discovery Creation_date: 2009-09-02 WG ID: 6lowpan Number_of_pages: 60 Abstract: This document specifies Neighbor Discovery optimized for 6LoWPAN. The 6LoWPAN format allows IPv6 to be used over energy and bandwidth constrained wireless networks often making use of multihop topologies. However, the use of standard IPv6 Neighbor Discovery with 6LoWPAN has several problems. Standard Neighbor Discovery was not designed for non-transitive wireless links, and the standard IPv6 link concept and heavy use of multicast makes it unpractical. This document specifies a new ND mechanism allowing for the efficient detection of duplicate addresses over entire LoWPANs, which also optimizes other ND operations. In addition, context dissemination, claim and defend address generation, and the support of Extended LoWPANs over Backbone Links are specified.

I would be much happier with this document if star-connected nodes were the exception rather than the rule. Can we add some more links in there so the reader will get used to the idea of meshes rather than trees? Most people who have done commercial deployments will tell you that stars and trees are lethal for reliability. As far as RFD vs. FFD goes, does anyone even make an RFD? I'd also recommend an update to the "typical characteristics" in section 1. * Under "low power" you're mixing RF transmit power ("up to 1000mW") and radio power consumption ("between 10 mW and 20mW"). Also, there's exactly one 802.15.4 radio that falls into that range (the DN2510). The rest are all substantially higher. * The specs on memory and processor horsepower are from the golden age of academic wsn research, and are almost a decade out of date. Look at what Freescale, Atmel, Jennic, etc. are shipping in volume. They are 32-bit cores (typically ARM7) running at tens of MHz, with tens of kB of RAM. Section 3: * Connectivity: I disagree with the association of "sleeping mode" with "intermittent" connectivity. There are many L2 protocols that allow tradeoffs between duty cycle and link BW. I would not call those nodes that sleep >99% of the time intermittent - they just have lower effective bit rate links. In particular, reading down in 4.1.1 the description of industrial monitoring connectivity as "always on for crucial processes, otherwise intermittent" does not fit with what's happening in the real world, and would tend to mislead someone not well versed in the field. * "several traffic patterns may be overused in LoWPANs" - overused? * "primordial" - I've seen networks like this, but I don't think that's what you really mean 4.1.2 Figures 4 and 5 You confuse "mesh" with "multi-hop" in your captions. Figure 5 has no meshing at all. maybe keep the caption, and put in some real meshing? Same thing for figure 6 and 7. I strongly disagree with the statement in 4.2.1 that this would work with a star topology, or a hierarchical star. 4.2.1 * "The network configuration and forwarding/routing tables are changed only in the case of node failure". Huh? Forwarding/routing tables will be updated *regularly* in a network like this due to connectivity changes. The RF environment is not static, even on a 'static' structure like a bridge, and even with line of sight. Every piece of metal on a bridge looks like a mirror to RF, and all of the mirrors move a little. Overall, I'm concerned that this document does not feel to me like it embraces the practical knowledge from real world deployments from *many* different companies using *many* different protocols. Did you talk to Arch Rock, Control 4, Dust, Ember, Emerson, Streetline, ...? We're not in the academic phase anymore - we've actually got lots of real-world data now, and much of it seems to be at odds with what's in this document. ksjp Geoff Mulligan wrote: > Folks, > This note formally starts the WG Last Call for comments on > draft-ietf-6lowpan-usecases-03.txt, "Design and Application Spaces for 6LoWPANs". > > The document can be found at: > http://www.ietf.org/id/draft-ietf-6lowpan-usecases-03.txt > > The document is intended to be submitted by this Working Group to the > IESG for publication as an Informational Document. > > Please review the document carefully (one last time), and send your > comments to the 6lowpan list.

Every piece of metal on a bridge looks like a mirror to RF, and all of the mirrors move a little. Overall, I'm concerned that this document does not feel to me like it embraces the practical knowledge from real world deployments from *many* different companies using *many* different protocols. Did you talk to Arch Rock, Control 4, Dust, Ember, Emerson, Streetline, ...? We're not in the academic phase anymore - we've actually got lots of real-world data now, and much of it seems to be at odds with what's in this document. ksjp Geoff Mulligan wrote: > Folks, > This note formally starts the WG Last Call for comments on > draft-ietf-6lowpan-usecases-03.txt, "Design and Application Spaces for 6LoWPANs". > > The document can be found at: > http://www.ietf.org/id/draft-ietf-6lowpan-usecases-03.txt > > The document is intended to be submitted by this Working Group to the > IESG for publication as an Informational Document. > > Please review the document carefully (one last time), and send your > comments to the 6lowpan list.

The document is in LC. The point of LC is to attract greater attention before the draft is submitted to the IESG for review. Kris is putting forward useful and constructive comments - many of which I have to agree with. I'm sure there are others that have not been able to provide their feedback as well. As for my feedback: - Section 1: Need an update w.r.t. common hardware capabilities. - Section 1.1: It's more accurate to say that networks are comprised of routers and hosts. Whether those hosts attach to a single router at a time depends on the implementation, and it's unclear to me whether attaching to 1 is more common than attaching to a few. What is common is that many networks are comprised of only routers. I'd also suggest changing the node-type terminology. For example, I'd prefer that *all* LoWPAN nodes in a mesh-under configuration should be called LoWPAN Hosts - none forward IP datagrams, but some forward 6LoWPAN frames. The terminology as shown in Figure 3 apply the same terms to both L2 and L3. - Section 1.1: Short address assignment does not have to be done by an 802.15.4 coordinator - 6LoWPAN ND provides a mechanism to assign them as well. - Section 3: - Power Source may include energy-harvesting as well, which have different characteristics from mains and battery-powered. - Connectivity should also include highly varying bit-rates due to differences in L2 duty-cycling settings. - Multi-hop communication is required in star as well. - Traffic patterns - avoid the word "overused" - Section 4.2.2: Can you clarify a bit more why nodes do not need to obtain globally unique addresses? Is each "star network" operating a private IPv6 network with it's own "star network"? It is mentioned many times in the doc that 64-bit link addrs are preferred because they are better handled in the new HC, but HC is designed to handle both 16 and 64-bit addrs - arguably 16-bit addrs allow for more efficient header compression. It is mentioned many times (e.g. Sections 4.1.2, 4.2.2, 4.3.2, 4.4.2, 4.5.2, 4.6.2) that link-local IPv6 addresses may be used when not communicating outside the LoWPAN - in a route-over configuration, you'll need routable addresses to communicate with other LoWPAN nodes not reachable over a single radio transmission. In those same sections, it is mentioned many times that a 16-bit address can only be used within a singe link-local scope. I don't see why this is a fundamental limitation. The current 6LoWPAN ND draft provides for unique 16-bit address assignment over an entire LoWPAN network - route-over or mesh-under. I think there are enough technical issues here that the draft requires a new revision. -- Jonathan Hui > Carl > > > -----Original Message----- > From: 6lowpan-bounces@ietf.org [mailto:6lowpan-bounces@ietf.org] On > Behalf > Of Kris Pister > Sent: Wednesday, September 02, 2009 1:59 PM > To: Geoff Mulligan > Cc: 6lowpan > Subject: Re: [6lowpan] WG last call on Use-Case draft document > > Eunah et al. > I would be much happier with this document if star-connected nodes > were > the exception rather > than the rule.

Not for 802.15.4-2006 - there are higher bit rates in the sub-GHz bands --- "Through their inability to transmit MAC layer beacons, RFDs can only communicate with FFDs in a resulting "master/slave" star topology." This isn't actually the case. There is a distinction between the implicit tree topology for network membership implied by 802.15.4 through the beacon/association mechanisms and actual topology formed by data communications. RFDs can transmit peer-to-peer providing they have joined through an FFD, assuming use of 802.15.4 network membership mechanisms, which aren't strictly necessary. I would generally avoid mentioning FFD and RFD. --- Robert Robert Cragie, Principal Engineer _______________________________________________________________ Jennic Ltd, Furnival Street, Sheffield, S1 4QT, UK http://www.jennic.com Tel: +44 (0) 114 281 2655 _______________________________________________________________ Geoff Mulligan wrote: > Folks, > This note formally starts the WG Last Call for comments on > draft-ietf-6lowpan-usecases-03.txt, "Design and Application Spaces for 6LoWPANs". > > The document can be found at: > http://www.ietf.org/id/draft-ietf-6lowpan-usecases-03.txt > > The document is intended to be submitted by this Working Group to the > IESG for publication as an Informational Document. > > Please review the document carefully (one last time), and send your > comments to the 6lowpan list.

We are the organizers and founders in partnership with TMCNET of the Smart Grid Summitand chief editors of the Smart Grid portal . We just finished our first summit and given that we organized the whole thing in less than a month, it was an enormous success, with a packed audience and a great set of speakers. We are excited about the January show in Miami. Also given that our portal has been around less than a month it's quite impressive that with regards to page hits, if the trend continues we will be by a large margin the most popular smart grid related online publication in the next month. The reason why I'm writing to you is because both Jon and I believe strongly that both the field area networks and home area networks should be about IP communications. It would probably be easier for us to jump on and support current trends and given TMCNETS huge readership we would still do well if we chose that route, however, apart from our objective news coverage, we really want our portal to be a hub for both our own opinions and for thought leadership in general with regards to best of breed strategies that will really help move this industry and society forward. Having said that, 6lowpan is something we have studied and believe to be possibly one of the right pieces of the Smart Grid vision. We would like to invite you as individuals, companies and organizations involved with 6lowpan to work with us in bringing the message of IP for home area networks to this industry on our portal and at our conferences. Please feel free to contact us directly. Best, Shidan _________________________________ Shidan Gouran Principal, Intelligent Communications Partners Suite 2200, 4950 Yonge Street Toronto, ON M2N 6K1 shidan@icpstrategies.com Office: (416) 218-5583 Cell: (416) 854-3017 Fax: (416) 221-4668 Web: http://www,icpstrategies.com __________________________________ --0016e644d0083dd3320472b0877e Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hi everyone, I would like to introduce ICP, a strategic consultancy focused= on the emmerging smart grid opportunity. =A0We are the organizers and foun= ders in partnership with TMCNET of the Smart Grid Summit and ch= ief editors of the Sm= art Grid portal.=A0

I'm now quite tied-up by other meeting in Argentina, so i will update the document applying the comments as soon as I return back (next friday). I also appreciate Daniel, Carl, Kihyong, Jungsoo, Hamid, Saif, and other 6lowpaners who sent the support.

Dear LoWPANers,

 

For those who did not get the news already, = I’m glad to let you know that the first standard that actually endorses our new = Header Compressoin work is out.

 

The ISA Standards and Practices Board has approved = "ISA-100.11a-2009: Wireless Systems for Industrial Automation: Process Control and Related Applications."  The standard has been published by ISA and can = be found at http://www.isa.org/ISA100-11a.

 

Because we do not have an RFC yet, the ISA-100.11a = standard had to mention an I-D version. But since we did not modify those parts = that ISA supports since then, it appears that ISA100.11a will effectively support = the final RFC.

 

Great work all J

6LoWPANners, First of all, I would like to express my support to moving forward the document. It offers very useful information for people working on the use of IP on top of LoWPANs. Regarding the objections expressed by JP Vasseur on the list, I would like to remark the following: >In this document, several characteristics of the issues and challenges of routing in >constrained and loosy environments are listed, nothing new to what is done in the >ROLL Working Group. IMHO, this is not true. ROLL has focused on application requirements, while 6LoWPAN has focused on 802.15.4-based requirements. There is, of course, some overlap between both, but I think this is not a problem. Instead, these two approaches complement each other gracefully. On the other hand, note that the first 6LoWPAN routing requirements draft was submitted almost a year before the ROLL (then called RL2N) BoF took place. >You mention that IP routing and what is referred to as Mesh- >Under Routing can be >used in such environment. So what is the aim of this document ? The aim of the document is clearly stated in the abstract of the document: 6LoWPANs are formed by devices that are compatible with the IEEE 802.15.4 standard. However, neither the IEEE 802.15.4 standard nor the 6LoWPAN format specification define how mesh topologies could be obtained and maintained. Thus, it should be considered how 6LoWPAN formation and multi-hop routing could be supported. This document provides the problem statement and design space for 6LoWPAN routing. It defines the routing requirements for 6LoWPAN networks, considering the low-power and other particular characteristics of the devices and links. The purpose of this document is not to recommend specific solutions, but to provide general, layer-agnostic guidelines about the design of 6LoWPAN routing, which can lead to further analysis and protocol design. This document is intended as input to groups working on routing protocols relevant to 6LoWPAN, such as the IETF ROLL WG. > 1) Is it to provide routing requirement for L3 (route over) ? > 2) Is it to provide routing requirement for L2 (mesh under) ? > If 1), then you may want to see with the ROLL WG whether some of the data could >be used for this WG that is not already covered by the existing routing requirements >documents. > If 2), what is the intent of the document since we do not rightly (at the IETF) intend to specify a L2 "routing" >protocol for a specific media such as 802.15.4. I think this reasoning is not valid and Carsten Bormann gave already a good explanation for this in the e-mail he sent to the list in August 7, as a reply to the e-mail you sent the same day. Furthermore, personally, I believe that this separation between L2 and L3 functionality is not that clear. For example, it is possible to find routes using IP addresses and performing packet/frame forwarding using L2 addresses. > Figure 1 shows the place of 6LoWPAN routing in the entire network > stack. > +-----------------------------+ +-----------------------------+ > | Application Layer | | Application Layer | > +-----------------------------+ +-----------------------------+ > | Transport Layer (TCP/UDP) | | Transport Layer (TCP/UDP) | > +-----------------------------+ +-----------------------------+ > | Network Layer (IPv6) | | Network +---------+ | > +-----------------------------+ | Layer | Routing | | > | 6LoWPAN +---------+ | | (IPv6) +---------+ | > | Adaptation | Routing*| | +-----------------------------+ > | Layer +---------+ | | 6LoWPAN Adaptation Layer | > +-----------------------------+ +-----------------------------+ > | IEEE 802.15.4 (MAC) | | IEEE 802.15.4 (MAC) | > +-----------------------------+ +-----------------------------+ > | IEEE 802.15.4 (PHY) | | IEEE 802.15.4 (PHY) | > +-----------------------------+ +-----------------------------+ > * Here, 'Routing' is not equivalent to IP routing, > but includes the functionalities of path computation and > forwarding under the IP layer. > Figure 1: Mesh Under (left) and Route Over routing (right) >The right part is what we do at the IETF, in ROLL. >The left part looks like a new "architecture" to me, an adaptation layer performing >routing.

In addition, the figure just illustrates what is defined in RFC 4944, which is the base document describing how to transmit IPv6 packets on top of IEEE 802.15.4 networks. As a final remark, from your e-mail, it seems like you are questioning the existence of the document. Let me remind you that the 6LoWPAN WG agreed some time ago on the current charter, which has the following item: 4. As a separate Internet Draft, "6LoWPAN Routing Requirements" will describe 6LoWPAN-specific requirements on routing protocols used in 6LoWPANs, addressing both the "route-over" and "mesh-under" approach. This document will be created and owned by this working group but is expected to be reviewed by the ROLL WG. This document will be informational. And another important point is that the WG reached consensus on adopting the document as a WG document almost a year ago in the IETF meeting in Minneapolis in November 2008. According to the minutes, you were there.

It won't be able to decode the 6LoWPAN Prefix Information Option, which replaces 4861's. Even if it were, it wouldn't get answers on its NS (no 6LoWPAN-wide multicasts!). Then, since it didn't NR, it probably wouldn't get packets from outside. > And the reverse, could a 6lowpan ND end device get commissioned via a > standard RFC4861 ND router? That depends on whether the implementer spent precious code space to be able to parse 4861 prefix information option. Again, the node will then get stuck on the NR. Why do you want to mix?

That of course isn't possible with nd-05 (as-is). Making it possible would require adding some complexity to LoWPAN nodes... is there a good reason for doing that? Questions: - Is there a need for an IPv6 node that only implements RFC4861 to participate (have a network interface) in a LoWPAN? - If there is such a need, how should it participate (as a host?, as a router?, single-hop only?). Such a participant wouldn't work with route-over LoWPANs nor sleeping nodes of course. - What is the use-case and scenario for such participation?

Node B is a node using 6lowpan ND - DAD will fail (nobody answers to NS) - Address resolution will fail (same) - NUD fails (same) - if the router does not also send standard Prefix Information Option in Ras (but only 6lowpan information option), -- prefix discovery fails (incl on-link prefixes) -- autoconfiguration fails Regarding node B:=20 - If node A does not respect the binding between its L3 and L2 address, (the assumption that the IPv6 suffix is based on the MAC, for instance if node A uses DHCP or CGA), node B will not be able to contact node A - the white board is not authoritative anymore (A does not register), - hence DAD fails for node B. 2 Now for a node using 6lowpan ND only in a pure 4861 network: - DAD will fail (the node does not send NS) - Address resolution will fail (same) - NUD fails (same) - prefix discovery, autoconfiguration fails (no 6lowpan Information Option in RA) - This node will just not work at all, but will not disturb other nodes.

That has not been a requirement nor an assumption so far from the WG. We assume that all LoWPAN nodes run 6LoWPAN-ND on their LoWPAN interfaces. We need to answer the questions I posed in an e-mail earlier. Is this something that is needed and why? How should it work? And what are the real use cases that are useful?

So applying it on a LoWPAN is non-standard.=20 When networks with new characteristics come up, there's a need for an IPv6-over-Foo work; Thus the work at 6LoWPAN. Whatever this WG comes up with, that will be how IPv6 operates on a LoWPAN. The rest is proprietary experimentation. At this point, we do not have a requirement for interoperability for RFC4861 nodes. If you want to add that requirement and thus impact the spec, then you need to justify your case: =20 - Can you build a workable solution with RFC 4861?=20 - What are the limits/trade offs? - What use cases do that satisfy? - Does such a use case really need to Interop with standard 6LoWPAN on a same link? Note1: there's no IPv6-over-Foo for 802.11 infra mode because the infra mode emulates a transit link like Ethernet at L2, and thus RFC 4861 applies. OTOH, 6LoWPAN ND and ROLL will be a perfect match for 802.11 adhoc mode. But then there's no requirement to Interop that with adhoc mode and it is wise not to collocate adhoc and infra. Note2: As soon as you go L3, you can interconnect nodes on alien link layers. That's what IP is all about. Would your use case be satisfied if the nodes connect via a router?

It destroys the byte-alignment of the Traffic Class field. It also hurts the (code-saving) similarities -04 had between the TF values 00, 01, and 10. Clearly, this is a regression. (Unfortunately, it is almost identical to the old version so I didn't notice the change in July.) As an editorial comment, it would help to just say that the meaning of DAC/DAM simply is the same as that for SAC/SAM for M=0. As another technical note: Are we sure that these changes really don't impact ISA100, which appear to be stuck on -04? I haven't managed to verify that yet.

They only use: 01: ECN + 2-bit Pad + Flow Label (3 bytes) 11: Version, Traffic Class, and Flow Label are compressed. ISA100 is mesh under. Do they effectively carries the ECN bits in the L2 header over the radio to enable each hop to set the bits. The ECN field is conceptually copied from the L2 to the 6LoWPAN header as the L2 header gets stripped upon reception. Thanks a lot for raising the flag though. And I agree that the version in 04 was better.=20 Jonathan?

First there must be a typo in section 2.1 IP Routing where it says: "... Routers on a single interface within the same link to overcome the non-transient nature of the link." My guess that it should be "non-transitive" instead of non-transient. Then there are a number of different ways of saying asymmetric and asymmetry in this section: I think that asymmetric and asymmetry would be enough? We have at least a mix of the following: asymmetric non-symmetric (asymmetric would be better?!) non-symmetricity (asymmetry would be much better) e.g.: "... the link but still has problems with non-symmetricity." => "... the link but still has problems with asymmetry." I am planning to implement 6lowpan-nd in Contiki OS and I might get back with more technical aspects when we have started the implementation work.

If you want to be precise in the text you call out, neither version sufficiently specifies how the fields are encoded - that specification is delayed until Section 2.2.1 in both drafts. Would you prefer to list ECN and DSCP separately and in the order that they appear in a LOWPAN_IPHC encoded header? For example: 00: ECN + DSCP + 4-bit Pad + Flow Label (4 bytes) 01: ECN + 2-bit Pad + Flow Label (3 bytes) 10: ECN + DSCP (1 byte) 11: Version, Traffic Class, and Flow Label are compressed.

So why don't we stick with the way this was done in -04, not risking any incompatibilities with ISA100? (Of course, we should wait until we fully understand the ISA100 situation.) > Would you prefer text that says they are the same with exception? > Or keep the text as is? When they (SAC/SAM and DAC/DAM) really are the same, or there is one value that only is allowed for SAC/SAM, I'd prefer to unify them (editorial preference). Technical preference is of course that we can have as much code reuse as possible. The wart, of course, is M/SAC/SAM = 1/1/00. Why do we have that again? 0/0/00 means exactly the same. Why is SAC=1 for this stateless case (I know, because we already took all four stateless cases.) If we really want to have a special multicast case, why don't we compress out at least the first byte of the address, which is always 0xFF in this case? (Changes for multicast don't impact ISA100.)

We have had in-room consensus for a number of IETF meetings now to deprecate that part of RFC 4944 as soon as HC is approved. But of course, we need to validate this consensus on the mailing list, in particular for something as grave as deprecating a sizable part of an approved standards-track document. So this is a special kind of Working Group Last Call -- not on a document, but on this single issue: Should we deprecate section 10 of RFC 4944 when the new context-based HC is approved? We have seen enough yes votes that I'm now mainly interested in hearing any disagreement. draft-ietf-6lowpan-hc documents good reasons for deprecation, but are there any reasons against? Please send your considerations against deprecation, if any, to the 6lowpan mailing list by October 19, 2009, 23:59 UTC. If nobody speaks up, we will reclassify section 10 of RFC 4944 as NOT RECOMMENDED by including some text like the one in ticket 55 in the HC draft, which then becomes a standards-track document with its approval.

Filename: draft-ietf-6lowpan-nd Revision: 06 Title: 6LoWPAN Neighbor Discovery Creation_date: 2009-09-22 WG ID: 6lowpan Number_of_pages: 61 Abstract: This document specifies Neighbor Discovery optimized for 6LoWPAN. The 6LoWPAN format allows IPv6 to be used over energy and bandwidth constrained wireless networks often making use of multihop topologies. However, the use of standard IPv6 Neighbor Discovery with 6LoWPAN has several problems. Standard Neighbor Discovery was not designed for non-transitive wireless links, and the standard IPv6 link concept and heavy use of multicast makes it unpractical. This document specifies a new ND mechanism allowing for the efficient detection of duplicate addresses over entire LoWPANs, which also optimizes other ND operations. In addition, context dissemination, claim and defend address generation, and the support of Extended LoWPANs over Backbone Links are specified.

Will be fixed in > nd-07. This was somewhat terse; let me supply some detail here. RFC 4861 is the standard ND protocol for IPv6. We are not changing that. In its section 1, RFC 4861 explains its domain of applicability. In particular, it says: Unless specified otherwise (in a document that covers operating IP over a particular link type) this document applies to all link types. However, because ND uses link-layer multicast for some of its services, it is possible that on some link types (e.g., Non- Broadcast Multi-Access (NBMA) links), alternative protocols or mechanisms to implement those services will be specified (in the appropriate document covering the operation of IP over a particular link type). So 4861 essentially says that the IP-over-X protocol has to say when 4861 does not apply unchanged. In other words, we have to update 4944 for 6LoWPAN-ND to take effect. This is why 6LoWPAN-ND updates 4944. ND-07 could add some language to this effect. It could also explain that 6LoWPAN-ND is only fulfilling part of this toned down "expectation" from RFC 4861: The services described in this document [i.e., RFC4861] that are not directly dependent on multicast, such as Redirects, Next-hop determination, Neighbor Unreachability Detection, etc., are expected to be provided as specified in this document. The reasons for deviation from this expectation are good, but it would help to make explicit that the expectation is not met here.

There's no incompatibility with ISA100.11a there. ISA100.11a only uses the stateful encoding format - or no compression at all.=20 - ISA100.11a does not use the unspecified address.=20 - It does not do any ND/DAD.=20 - It always compresses the IPv6 address.=20 In more details: - All of the traffic (but ne flow) uses the 16bit short addresses. A system manager assigns the short address and the mapping into an IPv6 address, a bit ala DHCP. Any remote address will be mapped into a local short address as well to be expanded by the backbone router. So ISA100 is fully stateful, and the short address is an index in the context - there's only one context. - The only exception is the join process. The joining of a new node is a special flow and the only one that uses a 64bits MAC-64 Link Layer Address. From the network layer standpoint, the flow is performed using the EUI-64 based Link Local Address and should theoretically be encoded in a stateless form. But for simplicity ISA decided to have an implicit state virtually indexed by the MAC-64 link layer address and thus uses the stateful encoding even there. The 16bit address and the corresponding IPv6 address of the node are assigned as part of the join process.=20 - Any flow is started under the control of the system manager that will pass the addresses of the remote node and other contract information such as QoS parameters. QoS parameters end up encoded in the flow label. DSCP in not defined at ISA100.11a so TF bits can be either 01 or 11. There's work at ISA100.15 and ODVA that aim at defining industrial DSCPs. When that happens, we might very well see this work retrofitted in a revision of ISA100.11a that would enable all the TF possibilities.

Here is a new list, I hope it better reflects the current state of the art. o Limited processing capability: the smallest common LoWPAN nodes have 8-bit processors with clock rates around 10 MHz. However, the most commonly used models have either 16-bit or 32-bit cores (typically ARM7), running at frequencies in the order of tens of MHz. o Small memory capacity: common RAM sizes for LoWPAN devices consist of a few kilobytes, usually 4K or 8K bytes, but reaching up to 256K bytes for high-performance models. o Low power: wireless radios for LoWPANs are normally battery- operated. Their RF transceivers often have a current draw of about 10 to 30 mA, depending on the transmission power level. In order to reach common indoor ranges of up to 30m and outdoor ranges of 100m, the used transmission power is set around 0 to 3 dBm. Depending on the processor type, there is an additional battery current consumption of the CPU itself, commonly in the order of tens of milliamperes. However, the CPU power consumption can often be reduced by a thousandfold by switching to sleep mode. o Short range: the Personal Operating Space (POS) defined by IEEE 802.15.4 implies a range of 10 meters. For real implementations, the range of LoWPAN radios is typically measured in tens of meters, but can reach over 100 meters in line-of-sight situations. o Low bit rate: the IEEE 802.15.4 standard defines a maximum over- the-air rate of 250 kb/s, which is most commonly used in current deployments. Alternatively, three lower data rates of 20 kb/s, 40 kb/s and 100 kb/s are defined.

Is it important to emphasize the use of "a single interface"? I'm curious why this was specified here (or why it was not added to the analogous definition of a LoWPAN Mesh Node). Are there LoWPAN nodes with more than one interface? If yes, can it be ruled out that they are routers? If no, shouldn't the number of interfaces be left open?
