This draft is a work item of the Traffic Engineering Architecture and Signaling of the IETF. Title : An Architecture for Use of PCE and PCEP in a Network with Central Control Authors : Adrian Farrel Quintin Zhao Robin Li Chao Zhou Filename : draft-ietf-teas-pce-central-control-01.txt Pages : 21 Date : 2016-12-05 Abstract: The Path Computation Element (PCE) has become established as a core component of Software Defined Networking (SDN) systems. It can compute optimal paths for traffic across a network for any definition of "optimal" and can also monitor changes in resource availability and traffic demands to update the paths. Conventionally, the PCE has been used to derive paths for MPLS Label Switched Paths (LSPs). These paths are supplied using the Path Computation Element Communication Protocol (PCEP) to the head end of the LSP for signaling in the MPLS network. SDN has a far broader applicability than just signaled MPLS traffic engineered networks, and the PCE may be used to determine paths in a wide range of use cases including static LSPs, segment routing, service function chaining (SFC), and indeed any form of routed or switched network. It is, therefore, reasonable to consider PCEP as a general southbound control protocol for use in these environments to allow the PCE to be fully enabled as a central controller. This document briefly introduces the architecture for PCE as a central controller, examines the motivations and applicability for PCEP as a southbound interface, and introduces the implications for the protocol. This document does not describe the use cases in detail and does not define protocol extensions: that work is left for other documents.

In fact, it had reached a high level of stability before being polled for adoption. With this revision, a couple of the authors have re-read it and we have fixed a few nits. So, over to the chairs for the next step, which we think is review by the chairs and WG last call. WG last call should, we think, be copied to the PCE list.

Not in base o IP pkt does augmentation o Eth does augmentation > Both approaches have issues. > Attendees came up a compromise of the two options as below. Workgroup feedbacks are appreciated: 3. In base model, grouping is defined, but schema tree is not defined for this section. o Performance metric is defined as a reusable grouping, either in the base model, or in a common types model. o The schema tree of the base model does not include this section so that OTN and DWDM users will not see the clutter. o For each technology that needs this section, a one-line "uses" statement is added to include this section to cover this feature.

+      |  &nb= sp;     +--rw app* identityref  // {rsvp, sr, = ...}

 

For draft 1), the curre= nt structure is not compatible. There are a few options:

 

    1.1 Restructure te link container= , which complicates everything existing:

 

augment /nw:networks/nw:network/nt:link:<= /p>

   +--rw te!

      +--rw config=

      |  +--rw te-= link-attributes

+      |  &nb= sp;  +--rw te-application* [app]

+      |   &n= bsp;    +--rw app* identityref  // {rsvp, sr, = ...}

>        = |     +--rw access-type?    &n= bsp;            = ;     te-types:te-link-access-type

>        = |     +--rw administrative-group?   = ;          te-types:admin-grou= ps

>        = |     +--rw te-delay-metric?   &nbs= p;             =  uint32

>        = |     +--rw te-srlgs

 

 

    1.2 Add some application flag for= the link and for each attribute,

    which also makes the model less u= sable and confusing:

 

augment /nw:networks/nw:network/nt:link:<= /p>

   +--rw te!

      +--rw config=

      |  +--rw te-= link-attributes

+        = ;   +--rw app-bit-map      &nbs= p;         bits // one bit for each= app

      |   &n= bsp; +--rw access-type?        =             &nb= sp; te-types:te-link-access-type

      |   &n= bsp; +--rw administrative-group?      &nb= sp;      te-types:admin-groups

      |   &n= bsp; +--rw te-delay-metric?       &n= bsp;          uint32

+     |   &nb= sp; +--rw te-delay-metric-bit-map?      &= nbsp;   bits

      |   &n= bsp; +--rw te-srlgs

+     |   &nb= sp; +--rw te-srlgs-bit-map?       &n= bsp;         bits

 

   1.3 Reuse information-source container,= which does not seem to be suitable:

 

      |  +--ro inf= ormation-source-entry* [information-source]

      |  |  += --ro information-source        &nbs= p;       te-info-source: ospf

      |  |  += --ro information-source-state

      |  |  |&nbs= p; +--ro credibility-preference?    uint16

 

      |  +--ro inf= ormation-source-entry* [information-source]

      |  |  += --ro information-source        &nbs= p;       te-info-source: ospf-for-rsvp

      |  |  += --ro information-source-state

      |  |  |&nbs= p; +--ro credibility-preference?    uint16

 

 

      |  +--ro inf= ormation-source-entry* [information-source]

      |  |  += --ro information-source        &nbs= p;       te-info-source: ospf-for-sr

      |  |  += --ro information-source-state

      |  |  |&nbs= p; +--ro credibility-preference?    uint16

 

   1.4 Keep current TE topology model stru= cture and let implementation

       do the mapping.=

 

- Discussed which model to hold performance metric (= base model, or packet)?

  > This section is needed for some technolo= gies, but not all technologies.

    If we put it into base model, som= e technologies need to ignore it;

    if we put it into technology augm= entation model, each augmentation

    needs to repeat the same augmenta= tion.

  > There are a few options:

    1. Optional feature in base model=

       o Not use in OT= N

       o Not use in DW= DM

    2. Not in base

       o IP pkt does a= ugmentation

       o Eth does augm= entation

  > Both approaches have issues.<= /p>

  > Attendees came up a compromise of the tw= o options as below.

    Workgroup feedbacks are appr= eciated:

    3. In base model, grouping is def= ined, but schema tree is not

       defined for thi= s section.

       o Performance m= etric is defined as a reusable grouping, either

         in = the base model, or in a common types model.

       o The schema tr= ee of the base model does not include this

         sec= tion so that OTN and DWDM users will not see the clutter.

       o For each tech= nology that needs this section, a one-line

         &qu= ot;uses" statement is added to include this section to cover

         thi= s feature.

 

Thanks,

The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing = ADs. For more information about the Routing Directorate, please see =E2=80=8Bhttp://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it wo= uld be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or= by updating the draft. Document: draft-ietf-teas-gmpls-resource-sharing-proc-05 Reviewer: Christian Hopps Review Date: 2016-12-06 IETF LC End Date: Unknown Intended Status: Informational Summary: =3D=3D=3D=3D=3D=3D=3D=3D This document is basically ready for publication. It has 1 minor issue and some nits that should be considered prior to publication. Comments: =3D=3D=3D=3D=3D=3D=3D=3D=3D I found the draft fairly well written, easy to understand with good references. I believe that after fixing the minor issue and nits, this informational draft will be ready for publication. This was the first TEAS draft I have reviewed, and as a result it may mean that my review is less in depth than others. Major Issues: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D No major issues found.

directories. This draft is a work item of the Traffic Engineering Architecture and Signaling of the IETF. Title : RSVP-TE Signaling Procedure for End-to-End GMPLS Restoration and Resource Sharing Authors : Xian Zhang Haomian Zheng Rakesh Gandhi Zafar Ali Pawel Brzozowski Filename : draft-ietf-teas-gmpls-resource-sharing-proc-06.txt Pages : 14 Date : 2016-12-08 Abstract: In non-packet transport networks, there are requirements where Generalized Multi-Protocol Label Switching (GMPLS) end-to-end recovery scheme needs to employ restoration Label Switched Path (LSP) while keeping resources for the working and/or protecting LSPs reserved in the network after the failure occurs. This document reviews how the LSP association is to be provided using Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling in the context of GMPLS end-to-end recovery scheme when using restoration LSP where failed LSP is not torn down. In addition, this document discusses resource sharing-based setup and teardown of LSPs as well as LSP reversion procedures. No new signaling extensions are defined by this document, and it is strictly informative in nature.

This draft is a work item of the Traffic Engineering Architecture and Signaling of the IETF. Title : RSVP Extensions For Re-optimization of Loosely Routed Point-to-Multipoint Traffic Engineering Label Switched Paths (LSPs) Authors : Tarek Saad Rakesh Gandhi Zafar Ali Robert H. Venator Yuji Kamite Filename : draft-ietf-teas-p2mp-loose-path-reopt-08.txt Pages : 17 Date : 2016-12-08 Abstract: Re-optimization of a Point-to-Multipoint (P2MP) Traffic Engineered (TE) Label Switched Path (LSP) may be triggered based on the need to re-optimize an individual source-to-leaf (S2L) sub-LSP or a set of S2L sub-LSPs, both using Sub-Group-Based Re-optimization method, or the entire P2MP-TE LSP tree using the Make-Before-Break (MBB) method.

Hi guys,

 

Huawei folks working o= n the TE Topology model implementation have brought to my attention that un= like TE nodes and TE links, TTPs do not have Underlay/Source/Supporting attributes. Note that because (in contras= t to TE nodes/links) TTPs are not independent entities in a TE topology (al= ways belong to respective hosting TE nodes), there is no need for Underlay and Source TTP attributes (could be derived f= rom the hosting TE node attribute). However, list of Supporting TTPs per TT= P is useful for the same reason as Supporting TE link/node – to let the client track abstract/log= ical entities to their respective real/physical ones.  I suggest addin= g the list. Let’s discuss.

Here I want to give some responses for the concerned questions about "PCE in Native IP network", which are initiated from different experts. Wish it can clarify some confusion points for this draft and put forward it some steps further. Question 1(from Danielle Ceccarelli): "We already have a solution for Traffic-Engineering in IP networks -- it is called MPLS." [Aijun Wang]: Traditional MPLS technology that is deployed in distributed manner can only do bandwidth reservation via the RSVP signaling protocol, can't meet the application QoS requirement in real time traffic network. The deployment of RSVP protocol is complex and it also brings large burden on the network devices. This is the main reason that the SR(Segment Routing) technology is emerged and popular in recent days. But as I mentioned during the presentation, SR now can only be deployed in MPLS and IPv6 network, and there is no similar solution for Native IP network. The draft "PCE in native IP network" is just to fulfill this aim, that is to say, to find and deploy one end-to-end path in underlying network upon the QoS requirement of application. Question 2(from Jeff Tantsura): " Would like to see better comparison with FlowSpec and BGP based solutions before we proceed" [Aijun Wang]: BGP flowspec should deploy specific policy for every application prefix in every on-path router, but the solution described in "PCE in native IP network" treats edge routers and other on-path routers differently: only the edge routers need to keep the policy for every prefix, the other on-path routers should only keep the policy for specific route to related edge routers, not the specific application prefix. This can relive the burden of on-path routers and has more flexibility and expandability during deployment. Question 3:(About the relationship with PCECC use-case draft)(from Lou and Dhru) [Aijun Wang]: We have described this in the abstract of the draft "PCE in Native IP network" (https://datatracker.ietf.org/doc/draft-wang-teas-pce-native-ip/), as the following: "This document defines the scenario and solution for traffic engineering within Native IP network, using Dual/Multi-BGP session strategy and PCE-based central control architecture. The proposed central mode control solution conforms to the concept that defined in draft [I-D.draft-ietf-teas-pce-control-function], and together with draft [I-D.draft-zhao-teas-pcecc-use-cases], the solution portfolio for traffic engineering in MPLS and Native IP network is almost completed." I also prefer to separate the two drafts in two tracks, one is for PCECC for MPLS network, the other for PCECC for Native IP network. Because after the use case, we should propose the related solution and extension proposal for PCEP. The solution and extension for these two categories use cases seems to have little similar characteristics. The author of these two drafts are overlapping, so we will cooperate with each other to forward these drafts. Do the above explanation make senses for the concerned questions? We are also eager to hear more value suggestions and comments for this scenario and solution. Best Regards.

directories. This draft is a work item of the Traffic Engineering Architecture and Signaling of the IETF. Title : Extensions to Resource Reservation Protocol For Fast Reroute of Traffic Engineering GMPLS LSPs Authors : Mike Taillon Tarek Saad Rakesh Gandhi Zafar Ali Manav Bhatia Filename : draft-ietf-teas-gmpls-lsp-fastreroute-07.txt Pages : 22 Date : 2016-12-19 Abstract: This document defines Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling extensions to support Fast Reroute (FRR) of Packet Switched Capable (PSC) Generalized Multi-Protocol Label Switching (GMPLS) Label Switched Paths (LSPs). These signaling extensions allow the coordination of a bidirectional bypass tunnel assignment protecting a common facility in both forward and reverse directions of a co-routed bidirectional LSP. In addition, these extensions enable the re-direction of bidirectional traffic onto bypass tunnels that ensure co-routedness of data paths in the forward and reverse directions after FRR and avoid RSVP soft-state timeout in control-plane.

- Continued discussion on the naming for MDLG. =

  > use NSRLG.

  > Indicates the easy to understand concept= completely opposite to SRLG.

  > Configuring abstract TE link has the NSR= LG requirements.

    When configuring an abstract TE t= opology, how a client can

    articulate that given n TE links = should be mutually SRLG disjoint,

    with their respective underlay TE= paths unknown and to be dynamically

    or semi-dynamically computed?

  > When a TE link is configured with N= SRLG, the intent is to have

    this link to be independent (not = to share fate, risk) with other TE

    links within the same group. This= independence is expected to be

    ensured by the provider with TE t= unnel supporting the link taking

    path in the underlay topology div= erse from the paths taking by the

    TE tunnels supporting other TE li= nks within the same NSRLG.

        &nbs= p;         

- Discussed and agreed to add default attributes for= connectivity matrix:

 

augment /nw:networks/nw:network/nw:node:<= /p>

Title : Framework for Abstraction and Control of Traffic Engineered Networks Authors : Daniele Ceccarelli Young Lee Filename : draft-ietf-teas-actn-framework-02.txt Pages : 32 Date : 2016-12-22 Abstract: Traffic Engineered networks have a variety of mechanisms to facilitate the separation of the data plane and control plane. They also have a range of management and provisioning protocols to configure and activate network resources. These mechanisms represent key technologies for enabling flexible and dynamic networking. Abstraction of network resources is a technique that can be applied to a single network domain or across multiple domains to create a single virtualized network that is under the control of a network operator or the customer of the operator that actually owns the network resources.

Hello,

We’d like , myself and other co-authors, to ra= ise the attention from the WG and the chairs on the next steps of the ACTN = info model draft

 

https://tools.ietf.org/ht= ml/draft-leebelotti-teas-actn-info-05.

During the IETF 97 meeting, after the presentation o= f version 5, a poll was done (quoting the minutes):

“How many people think that this is usefu= l work? [A reasonable number of hands]  

 How many have read? [About the same] = ; 

 How many think that this should be adopte= d as a WG document? [about the same]. 

 Chairs will discuss next steps (and go fr= om there.)”

 

The authors believe the draft can be part of TEAS wo= rk as WG document and since it is passed one month from our meeting, weR= 17;d like to hear how to proceed on this draft in the prospective of next I= ETF 98.

 

We take the chance to wish everybody  “Me= rry Christmas and Happy New Year”.

Thanks

 

Sergio on behalf of co-authors

I think you really (really, really!) need to NOT call it stateless RSVP. You are abolishing "soft state" in favour of "hard state" as you say quite clearly in section 2.2. This is a good discussion to have, but it is very definitely not stateless. I think that if you don't tidy that up you will find that your readers enter the document confused and possibly upset :-) Section 1 references 5439 in support of the statement "when the refresh interval is increasing, a degree of functionality is lost." 5439 does, indeed say this, but the context is lost in your reference. The full quote from 5439 is: | However, it should be noted | that RSVP-TE's soft-state nature depends on regular refresh messages; | thus, a degree of functionality is lost by increasing the refresh | time. This loss may be partially mitigated by the use of the RSVP-TE | Hello message, and can also be reduced by the use of various GMPLS | extensions [RFC3473], such as the use of [RFC2961] message | acknowledgements on all messages. One of the debates around [I-D.ietf-teas-rsvp-te-scaling-rec] has been quite how large to increase the refresh time. You are proposing to go to the limit (i.e., no refreshes) and this is as attractive for packet networks as it was for non-packet networks ten years ago. But the question to consider is just how much house-keeping is needed to clear up orphaned LSPs. While it is clear that a central controlled or an operator can touch the network nodes to clear up stale state, it gives rise to a number of concerns: - increase in complexity of the system - duplication of LSP state in the network and in the controller - resolution of disagreements over state in the network and the controller - recovery or redundancy issues with the controller. But my favourite concern is whether the operator is willing to have an external party come into the network and remove LSP state when that LSP might really be needed. Bugs and fat fingers have to be traded against customer services. In practice, therefore, while the use of management commands to clean up state is a nice approach, I wonder whether you would consider a refresh interval of one day to be a practical and scalable alternative that ensures that everything is kept tidy. My last question to you is whether you think we could find a way to fold your thoughts into [I-D.ietf-teas-rsvp-te-scaling-rec].
