Bruce - I think you're the guy with the most up to date draft text. Here is 
some proposed text:

.nh 1 "IANA Considerations"
.lp
Section 1.2 proposes a new protocol type, RSVP-E2E-IGNORE, which is used to 
identify a message which routers in the network core will see and must 
evaluate the egress interface type to determine what they must do with.

Section 1.4.9 describes the manner in which the Router Alert is used in the 
context of this specification, which is essentially an algorithmic 
numeration of the number of aggregation nesting levels it is passed. RFC 
2113, the IPv4 Router Alert, has the option simply ask the router to look 
at the protocol type of the intercepted datagram and decide what to do with 
it; the parameter is additional information to that decision. RFC 2711, the 
IPv6 Router Alert, turns the parameter into an option sub-type. As a 
result, the IPv6 router alert option may not be used algorithmically in the 
context of the protocol in question. We therefore request IANA to assign a 
block of 32 values which we may map to nesting depths 0..31, hoping that 32 
levels is enough. Since RFC 2711 assigns the values 0, 1, and 2, we suggest 
that these values occupy the range 3..35.

Section 3.2 discusses a path error code NEW-AGGREGATE-NEEDED, to be assigned.

Sections 3.3, 3.4, and 35 describe extensions to three object classes: 
Session, Filter Specification, and Sender Template. These require two 
common C-Types to be specified for the aggregator's address, which we call 
the RSVP-AGGREGATE-IP4 and RSVP-AGGREGATE-IP6. The same number should be 
used for all three objects, as is done for IPv4 and IPv6 address tuples in 
RFC 2205.

I don't think this is the right model for an IANA Considerations
section.  When an RFC assigns particular values to existing
parameter series, it just does it.  The RFC Editor and IANA
make it right.  The IANA Considerations section is used (only)
when an RFC defines a NEW parameter series, and exists to program
the IANA on how to assign FUTURE values in that series.

Apologies if I am misunderstanding...

Bob

well, we changed it as instructed, to make IANA/RFC Editor happy. Could you 
suggest text that would make you happier?

Bob,

IANA asked IESG to make the IANA Considerations in this draft
point out what section each IANA action was in, and to be 
explicit about the requests made.  The concern was serious enough
for the fixes to be the obstacle for transmitting the doc to
the RFC Editor (it has passed IESG for PS except for this).

IESG now gets guidance from IANA directly on every document we pass
to standards track.  My understanding is that new/revised specs:
1. always include IANA Considerations
2. give explicit instructions in that section, even if it
   is just to point back to the text, not only for forming new registries

I think a side benefit of this is for education:  spec writers (the
Internet authorship group has become very large), WG chairs,
even we IESG who may forget things (as well as coming in new) find 
instruction in each spec about how IANA protocol number registrations 
work and are used.

I've added IANA to the cc list, and they should feel free to speak up
if I've misstated...

I hope the ISSLL WG (I've left the WG cc'd) isn't saying "sheesh, what
does this have to do with ISSLL?", even though it's about a WG doc.

Allison

This draft is a work item of the Integrated Services over Specific Link Layers Working Group of the IETF.

	Title		: RSVP  Reservations Aggregation
	Author(s)	: F. Baker, C. Iturralde, F. Le Faucheur, B. Davie
	Filename	: draft-ietf-issll-rsvp-aggr-04.txt
	Pages		: 41
	Date		: 09-Apr-01
	
A key	problem	in the design of RSVP version 1	is, as noted in
its applicability statement, that it lacks facilities	for
aggregation of individual reserved sessions into a common
class. The use of such aggregation is	required for
scalability.
This document	describes the use of a single RSVP reservation
to aggregate other RSVP reservations across a	transit	routing
region, in a manner conceptually similar to the use of Virtual
Paths	in an ATM network. It proposes a way to	dynamically
create the aggregate reservation, classify the traffic for
which	the aggregate reservation applies, determine how much
bandwidth is needed to achieve the requirement, and recover
the bandwidth	when the sub-reservations are no longer
required. It also contains recommendations concerning
algorithms and policies for predictive reservations.

	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

In the chapter: '4.2.3 Per-flow RSVP', the mechanism supporting per flow
signaling in DiffServ region, which should be described in referece:    

[3]  Berson, S. and R. Vincent, "Aggregation of Internet Integrated
Services State", Work in Progress.

seems under developing. But there was an internet draft
'draft-berson-rsvp-aggregation-00.txt' previous to above reference.
Could anybody tell me where I can get it, or where I can find the trace
of this issue going?

Thanks.

My question is about e2e QoS reservation which is in a
manner of per flow reservation(not aggregate RSVP)in
DS region. When the RSVP messages go through DS region
to collect the information of the availability of
resource in DS region, how does the DS region treat
them:

1. Is the Adspec in sender PATH message updated by the
RSVP awared nodes in DS region? If it is, how can DS
region interpret the meaning of Adspec since Adspec is
defined for IntServ?

2. Or the updating of Adspec can be ONLY done at
border router of DS region? 

If there is any statement of my question, what is
that?

Regrads,

Steven

Steven,

As far as I know there is no reservation protocol for diffserv yet and RSVP 
is not suitable, therefore it is not being used. Thus, diffserv does not 
provide reliable e2e QoS at this moment.

Another important point is per-flow requests does not go beyond edges, when 
a customer requests a service, the request is handled in edge.

For more information look at: rfc2998

In any case... this is a topic for the ISSLL WG alone, not diffserv. Diffserv's
charter specifically excludes signalling. If you want to continue this thread,
please drop diffserv from the CC: list

hi,

My initial perception of the motivation for Intserv/diffserv interworking
was that the mathematically bound QoS guarantees associated with Intserv,
when combined with Diffserv would bring better QoS performance to the
end-users than when Diffserv alone, with its less strict QoS guarantees is
used. Thus from this viewpoint, given a number of network elements, the
more number of Intserv network elements you have in the end-to-end path
the better would be the QoS performance.

However, from RFC 2998 + other documents on the web, I've come to the
conclusion that the main motivation for using Intserv with Diffserv is the
signalling control and end-to-end semantics that RSVP/Intserv brings to
the local behavior definition inclination of Diffserv. The first three of
the four benefits mentioned in Section 2 of RFC 2998:

*Resource Based Admission Control
*Policy Based Admission Control
*Assistance in Traffic Identification/Classifica
*Traffic Conditioning

seem to support this.

Can I conclude that my initial perception was wrong and the second
viewpoint is more in line with the IETF sentiment?

thanks for any inputs.

                        Final Call for Papers

2nd Workshop on Quality of Service in Distributed Object Systems

                   Workshop #2 at ECOOP 2001
        http://www.dist-systems.bbn.com/confs/2001/QoSDOS/

            Budapest Hungary: June 19, 2001 (Tuesday) 


The workshop addresses the state of the art and the future of 
Quality of Service management in distributed object systems. 
The objective is to provide presentations and discussions
about the influence of QoS provision on the object model. 
An additional focus is put on component-based systems and 
the influence of QoS provision on the component specification and
proper mapping to the underlying distribution infrastructure. 

Topics include, but are not restricted to 

    - Modeling QoS: suitability of object oriented modeling 
      techniques, influences of QoS provision on the object 
      model, e.g. type systems 
    - Specification: Use of containers to specify and enforce QoS
      properties for a component.
    - Structure: AOP, open implementations 
      design patterns, or contract aware components 
    - Implementation: Use of components for implementing ORBs
    - Scope of QoS-integration: generic integration, multi-category 
      support, impact on architecture and underlying object-model 
    - Management: integration of QoS management and network and 
      application management 
    - Experiences: of QoS integration in OO-Middleware platforms 
    - Specialized QoS platforms vs. extending existing platforms 
    - Bind-time QoS integration: Naming, Trading, and Negotiation 
      of QoS in open distributed systems 
    - Accounting and Pricing of QoS 

Submission Process:

A one to two page extended abstract describing your research is 
required. The paper will be distributed to the other participants 
and published on this website. The preferred format is
pdf or html. Participants should also be prepared to give a 15 minute 
presentation on their research. To facilitate discussion, workshop 
is limited to 15-20 people. 

Send the paper to qosdos@bbn.com by April 17, 

A workshop summary will be published as part of ECOOP 2001 Workshop Reader.

As a dot.com professional you know that it is essential to your teams' 
success to advertise your web site, business, product, service, or your 
organizations' cause to the masses. You also know that your marketing and 
advertising budget limits your options.

If you are a Fortune 500 corporation, you have the advantage of being able to 
book 30 second TV spots during the SuperBowl. Most of us are not in that 
position though. Besides, did you know that something on the order of 92% of 
TV viewers run to the washroom at commercial breaks during the program, 
thereby missing the expensive commercial spot.


Q: Of all the various advertising mediums which do you feel is most effective,
 in cases when you require your prospect to remember your telephone number or 
web address?


Let's outline and agree on a list of the main advertising and marketing 
mediums first:


- Television Commercial
- Television Infomercial
- Internet Banner Ads (paid for on a click-through basis)
- Internet Banner Ads (paid for on an impression basis)
- So-Called opted-in email list rental and broadcast
- Radio Commercial
- Print Media (Newspapers, Magazines)
- Print Media (Hand-Outs)
- Trade Shows
- News or Media organization story or profile on your project
- Affiliate Links
- Signage
- Telemarketing
- Direct Mail 
- Broadcast Fax (not personalized to its recipients)
- Broadcast Fax (personalized and to the Attention of its recipients)
- Targeted Broadcast Email (personalized or not)


Now consider the effectiveness of each advertising choice, remembering that 
in many cases your audience must still remember a telephone number in order to 
contact you.


Q: Which is the least costly and most effective?


E-mail marketing works! Why? There are many reasons, but primarily because 
people are focused on their monitors while checking their e-mail. Totally 
focused. In addition, they have a hard copy of your ad on their hard drive, 
and it is simple for them to forward the ad to their friends and
associates as well.


You can tell your story with more words and target your list to particular 
types of recipients or geographical areas. We offer some of the best delivery 
and bulk e-mail prices on the Internet. Bulk e-mail can get you the best 
exposure on the net. What makes this kind of advertising so effective is the 
fact that you go to the potential customer. Not like search engines or print 
ads that the potential customer has to do all the searching.  Dollar for 
dollar bulk e-mailing is also the most economical.  We do all the mailing for 
you. You just provide us with the ad!  It's that simple!

In theory, for Diffserv, ADSPEC would be updated at
the edge or border routers and not the core routers.

In practice, however, I'm not sure how many implementations 
actually update ADSPEC for Diffserv border or edge
devices. The Diffserv/RSVP implementations that I was 
aware of and involved with, did not update ADSPEC.

Parekh and Gallagher, in Infocomm '93, demonstrated what is necessary to 
have a predictable behavior in a network. It has two elements: you have to 
know how much traffic there is, and you have to have the queuing points 
(host and router) behave predictably. If those two things are true, you can 
mathematically calculate the end to end delay. They give equations.

Diff-serv, which is a data plane tool, enables us to scalably make the 
router do predictable things, given that the amount of traffic and the 
bandwidth available are known.

TCP will put a stable amount of traffic into the network; unfortunately, it 
approximates the cliff rather than the knee. With red we can bring that 
down to the knee, and with ECN we can do so without dropping traffic. So if 
the routers behave predictably, we can create a quite predictable network 
for TCP-based applications.

But voice/video don't respond to delay, ECN marks, or loss; each such 
application sends at a constant rate while it is sending, and using 
diff-serv alone the number of senders (and therefore total traffic load) is 
unbounded. Hence, using diff-serv alone, one cannot build a predictable 
voice network. The alternatives are (1) to provide effectively infinite 
bandwidth for voice, so that it is never significantly delayed regardless 
of user count, or (2) to know how many calls there are in the network with 
what characteristics, and refuse excess calls. In networks that consider 
communications capability to be a cost of doing business as opposed to the 
business itself, (2) becomes necessary, and (2) is the province of 
int-serv, a control-plane tool.

Hence, for voice/video, we must use int-serv and diff-serv together.

Minutes of the ISSLL WG Meeting
50th IETF - Minneapolis, MN.
Tuesday, March 20, 2001 13:00-14:00


ISSLL held a one-hour meeting at the 50th IETF. Issues related to several
Intserv/Diffserv documents were discussed.

* draft-ietf-issll-rsvp-aggr-03.txt

The chair gave a short summary of the status of this draft.  It was
submitted to the IESG for publication as a RFC months ago.  At the
December, 2000 WG meeting the cognizant AD (Allison Mankin) gave a short
presentation explaining the concerns, which focused around the draft's
requirement that the IP next-protocol field be altered as the packet
traveled through routers.  She suggesting that the concerns could be
resolved either through technical revision or through a more detailed
security concerns section.

After some discussion at the 49th IETF meeting and consideration among the
authors, a new security section was drafted and a revised version of the
document was submitted before the deadline for this meeting. No further
comments on the revised version have been received on the mailing list.

At the time of the WG meeting, the IESG was still reviewing this revised
version.

[Ed. after the meeting, the IESG approved publication of the draft, subject
only to some clarification of the IANA considerations section. That
clarification led to a -04 version draft being submitted. This version will
now go to the RFC editor.]

* draft-ietf-issll-rsvp-cap-02.txt

This draft defines the RSVP CAP object.  The -02 version of this draft,
incorporating previous comments, was submitted in February.  A key change
was removing most of the explanatory material into a separate document,
draft-hamid-issll-rsvp-cap-dsmark-00.txt, leaving this one as a standalone
spec.

Comments from the mailing list and the chairs identified several small
issues with this document. These points include:

1) Sections of the previous document that specified bit assignments were
incorrectly removed to the explanatory document. Bit assignments should be
part of the standard, not the explanation

2) The document presently implies that each capability will only require
one bit. There is no reason that this need be true, and the limitation is
not needed.

3) Message processing rule descriptions need to be either completely
generic or specified per-capability, rather than in a general section.

The author of the draft was unable to attend the meeting.  In his absense,
the chairs proposed revising the document to address these issues by a)
editing the present definition of the CAP object itself to include only
generic (not per-capability) information and to not limit the definition
of a particular capability, and b) adding new sections for each defined
capability, giving bit assignments and message processing rules for that
capability. The intent is that new revisions of the document would be
issued if and when new capabilities are defined.

A brief discussion did not reveal any objections to this approach from
meeting attendees.  The chairs will draft a note to the mailing list and
forward comments to the draft author.

* draft-ietf-issll-ds-map-01.txt

[Ed. The chairs note that one of them is also an author of the current
version of this draft.]

This is the "service mapping" draft, which gives advice about using
diffserv technologies to cause a DS cloud to effectively emulate an
intserv "network element" and thus play a part in an intserv end-to-end QoS
path.

The current version of the document was written some time ago and has not
been modified in any significant way in some time.  However, in the view of
the authors, it is missing some important sections and thus is still work
in progress. At this meeting, the chairs raised the question of whether to
continue work on the document, and if so, what path forward would be most
useful:

Specifically, the chair raised three questions as a starting point for
discussion.

1: Is the document, either as it stands or as it might stand, useful?

2: Present practice is to implement and use the defined intserv services,
particularly Guaranteed, in ways that do not completely match the RFC
definitions.  Should the document focus on mapping diffserv to the defined
services, or to some approximation of these services that is emerging from
current practice? If so, should we attempt to write down these
approximations, either in this document or in a separate one?

3: One specific technical area that is not addressed in the current
document is statistical approximations of G-like services. (CL is already
defined in this way). Should the document specifically attempt to capture
the current state of knowledge in this area, even though that knowledge is
evolving fast?

A vigorous discussion ensued. The results of this discussion can be
summarised as:

1) There was substantial concensus in the meeting that the document is
useful and should be completed.  Some speakers expressed the opinion that
the document is useful as it stands now, and should be published as is even
if no further technical work is done.

2) There was substantial concensus in the meeting that the document should
focus on implementing the intserv services as they are actually being
used, rather than strictly following the RFC definition.

3) There was substantial concensus that it would be useful to crisply
document the assumptions and approximations made by current implementations
of the intserv services, as a starting point for doing the above. The
question of whether this should be a separate document or a section of the
mapping draft was left open.

4) Some speakers suggested that the intserv service definitions themselves
were subject to misunderstandings that led to problems.  A document or
section of the current draft discussing these issues was suggested.

5) There was an extended discussion of whether it would be useful to define
one or more new IntServ services with definitions that captured what people
perceive as the current requirements for VoIP. The meeting was more or less
evenly split on this topic, with several speakers arguing for a new service
at the Intserv level and several others arguing that appropriate selection,
implementation and approximation of the existing services in different
environments is a simpler and adequate approach.  A complicating factor in
this discussion was point 4, above, which raised the possibility that some
concerns about the current specs were based on interpretation of the spec
document rather than technical unsuitability.

Based on this discussion, and followup discussions with the document
authors and people that expressed interest in the meeting, the chairs will
draft a proposal for revising this I-D and forward it to the mailing list
for discussion as soon as practical.

so, can i conclude that the primary motivation for the Intserv/Diffserv
interoperation is the signaling that control plane Intserv brings to data
plane Diffserv for such voice/video flows that do not use TCP? with other
benefits being... able to perform better resource mgmt in Diffserv clouds,
fine-grained policy control etc (the 4 benefits in RFC 2998). 

ergo, from the operational "real world" viewpoint, my ISP would introduce
Intserv/Diffserv for the above reasons and NOT for the tighter qos
guarantees attributes of Intserv. this perception also seems to be
supported by a look at the Intserv/Diffserv network model: Intserv n/w
elements are at the stub n/ws where congestion is less likely, and hence
perflow intserv is unlikely to bring significantly better qos guarantees
(as opposed to extending Diffserv all the way to the stubs).

on the other hand, from a purely academic "scientific" perspective,
perhaps investigating the interworking problem from my initial perception
("hard qos guarantees Intserv benefits less strict qos guarantees
Diffserv") is worthwhile, thesis-wise :-).

thanks.

given that controlled load presumes a common queue for all voice traffic, 
scheduled using priority or similar scheduler, I'm not sure I see a 
distinction. Controlled Load can be read pretty directly as "per-microflow 
signalling for EF-managed microflows". The difference here, I believe, is 
that we would like to see aggregate signaling as well as aggregate data 
management.

When you talk about fine-grained data management, you are talking about the 
Guaranteed Service, which presumes the characteristics of per-flow WFQ, 
although somehow it manages to not actually require a WFQ/WRR algorithm. 
This is something that is eminently possible using calendar-queue-scheduled 
WFQ algorithms, but has potentially interesting scaling properties.

very possibly. You could start out by arguing that the guarantees differ, 
and say why you think that. hint: with a control plane, you get told what 
you are guaranteeing. But I wouldn't compare a control plane solution to a 
data plane solution - the control plane isn't going anywhere without a data 
plane, and controlled load has the SAME data plane; the only thing that 
differs is how the classifier works. You want to explore what not having a 
control plane does to arbitrary amounts of voice and video.

Hi,

Once again it's time to clean up the ISSLL WG mailing list - lots of 
bounces from dead addresses. Some time over the next 24 hours I'm 
going to remove all of the addresses that are consistently getting 
permanent errors.

When I'm done I'll send another note to let you know. If you don't 
get the second note within a day or two, Something Bad has happened. 
If, at that point, you still want to be on the list, please either 
let me know or just resubscribe.

Regards,
John W.
