This document proposes an enhanced mechanism for LMP link
verification that is independent of the data encoding
type.  The general proposal is to use the transmission of
light by the sender and recognition of the presence or
absence of light by the receiver to identify port
mapping.  The proposal includes minor extensions to the
existing messages to implement this extension to the link
verification procedure.

Title : Generalized MPLS Architecture for Multi-Region Networks Author(s) : D. Papadimitriou, M. Vigoureux et al. Filename : draft-vigoureux-shiomoto-ccamp-gmpls-mrn-00.txt Pages : 27 Date : 2002-10-29 Most of the efforts on Generalized MPLS were dedicated to environments including single switching capability devices, as such, the complexity raised by such control planes were equivalent to the one expected in classical IP/MPLS networks. The fundamental reason being that the definition of the control plane IP based protocol suite for Label Switch Routers (LSR) or Optical Cross-Connects (OXC) has exactly the same level complexity. The present document analyses the various GMPLS aspects when considering envinronments including combined LSR û OXC devices. The latter covers opaque, service transparent and fully transparent (i.e. photonic) data planes. The intent of the first release of this memo is to demonstrate that these aspects may not be as straightforward as they may appear in first approach.

Konishi Filename : draft-seno-path-quality-verification-00.txt Pages : 8 Date : 2002-10-25 This draft proposes a framework for path quality verification over an all-optical network. Because it will be difficult to ensure quality of a dynamically established path over an all-optical network, it may be useful for network providers to have means to verify quality of a path before it is served to the subscribers. This draft proposes a framework for such means, including requirements behind them and a path continuity check mechanism to verify optical-level path quality upon a path's establishment by the GMPLS signaling.

With respect to the Remote Interface IP Addres TLV, is there really any reason to include it with a value of 0.0.0.0 for a multi-access link? I can't see how there could be a compatibility issue since the rough count on the list revealed more implementations that omitted the TLV altogether. 2. With respect to more than two routers on a multi-access network, it seems there is considerable support for allowing this even though it is not fully specified. Could you add something along these lines to the second paragraph of the limitations section: "Operation over multiaccess links with more than two devices is not specifically prohibited. TE operation and the use of reservation state is a matter for further study".

The IESG contact persons are Bert Wijnen and Scott Bradner. Technical Summary Document 'Generalized MPLS - Signaling Functional Description' describes extensions to MPLS signaling required to support Generalized MPLS. Generalized MPLS extends the MPLS control plane to encompass time-division (e.g. SONET/SDH ADMs), wavelength (optical lambdas) and spatial switching (e.g. incoming port or fiber to outgoing port or fiber). This document presents a functional description of the extensions. Protocol specific formats and mechanisms, and technology specific details are specified in separate documents. Document 'Generalized MPLS Signaling - CR-LDP Extensions' describes extensions to CR-LDP signaling required to support Generalized MPLS. Document 'Generalized MPLS Signaling - RSVP-TE Extensions' describes extensions to RSVP-TE signaling required to support Generalized MPLS. Working Group Summary These documents originated in the MPLS WG. They were transfered to the CCAMP WG in early 2001. WG Last Call was posted to both WGs to ensure all involved people would review. Quite a number of itterations were needed before the WG could reach consensus on all the details.

Title : End-to-End VoIP Header Compression Using cRTP Author(s) : J. Ash, B. Goode, J. Hand Filename : draft-ash-e2e-crtp-hdr-compress-00.txt Pages : 9 Date : 2002-10-18 VoIP typically uses the encapsulation voice/RTP/UDP/IP, wherein the packet header is at least 40 bytes, while the voice payload is typically no more than 30 bytes. VoIP header compression can significantly reduce the VoIP overhead through various compression mechanisms. This is important on access links where bandwidth is scarce, and can be important on backbone facilities, especially where costs are high (e.g., some global cross-sections). In this draft we propose to re-use the methods in cRTP to determine the header compression context and to use the cRTP session context ID to route a compressed packet between the ingress and egress routers.

Please reread section 9.5.2 second paragraph. I reread the paragraph you mention from section 9.5.2 (Procedures for the Restarting node): "If the forwarding state was preserved, then the node initiates the state recovery process. The period during which a node is prepared to support the recovery process is referred to as the Recovery Period. The total duration of the Recovery Period is advertised by the recovering node in the Recovery Time parameter of the Restart_Cap object. The Recovery Time MUST be set to the duration of the Recovery Period in all Hello messages sent during the Recovery Period. State that is not resynchronized during the Recovery Period SHOULD be removed at the end of the Period." Could you please clarify why my statement is incorrect? If N1, N2 is the restarting order and if N2 cannot detect that N1 has restarted then N2 will send Path with Suggested Label to N1 according to 8-th paragraph in the same section.

If you want to discuss issues with drafts at the Atlanta meeting please request a slot to do so, by sending mail to the wg chairs. As always the slots will be allocated for discussions according to what is outlined below. Ron and Kireeti ---------------------------------------------------------------- It is not the purpose of a WG session to have presentation of the content of a document. It is assumed that all attendees will have read the drafts in advance of the meeting. For documents that are work-in-progress, the presentation should cover issues resolved since the last draft followed by open issues and controversial topics with the intent to reach a resolution of said issues and topics. For new work items, the presentation should focus on what the problem is and why it is necessary for the work group to address it. Further it should be either shown how it falls within the existing charter or why and how the charter should be extended to encompass it. The solution should only be sketched. The appropriate way of bringing new work to the working group is to send a draft to the mailing list and promoting discussion on the list. Slots on the agenda should be used to discuss outstanding topics that has not be solved on the mailing list. For new proposals addressing issues where work-in-progess the presentation should focus on the (perceived) short-fallings of the existing work and why those issues need to be addressed both in terms of why they are required and why they cannot be addressed in the existing work. the new work must be related to existing work (i.e. compatible, mutually exclusive, outright replacement). Finally, the new solution should be sketched, explaining how the solution overcomes those issues. The primary purpose of this last part is to allow commentary from the floor, it should not be orientated toward selling the idea. In all cases only a limited number of slides should be used. Speakers should budget their at least 25% of their time to allow for questions. Individual contributors: When requesting time on the agenda, please indicate how your contribution supports the WG charter.

On page 13 last sentence of Section 4.3.1 is stated that the MESSAGE_ID and related objects are defined in [RFC2961] and are used when refresh reductions is supported. What about the case I want to use MessageId and MessageId Ack just in order to improve the reliability of the G.RSVP-TE message transmission? Moreover RFC2961 page 5 last sentence of Section 2 states: "Note, a node that supports reliable RSVP message delivery (Section 4)but not Bundle and Srefresh messages, will not set the Refresh-Reduction-Capable bit." that in my understanding means that I can use MessageID and MessageID Ack without implementing refresh reduction. Is it correct? If yes can you please correct the Section 4.3.1 sentence?

Title : COPS usage for Path Computation Servers (COPS-PCS) Author(s) : M. Brunner Filename : draft-brunner-mpls-cops-pcs-00.txt Pages : 7 Date : 2002-9-5 This memo proposes to use COPS for the communication between a Label Switching Router (LSR) and a Path Computation Server (PCS). Path computation is in much regard a complex function and might be out- sourced. For this reason a protocol between an LSR and a Path Computation Server is needed. This memo proposes to use COPS as a base protocol for that task.

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-brunner-mpls-cops-pcs-00.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or 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. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft. --==========01767743========== Content-Type: multipart/alternative; boundary="==========01772099==========" --==========01772099========== Content-Type: message/external-body; ACCESS-TYPE=mail-server; SERVER="mailserv@ietf.org" Content-Transfer-Encoding: 7bit Content-Type: text/plain Content-ID: <2002-9-5121834.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-brunner-mpls-cops-pcs-00.txt --==========01772099========== Content-Type: message/external-body; name="draft-brunner-mpls-cops-pcs-00.txt"; SITE="ftp.ietf.org"; ACCESS-TYPE=anon-ftp; DIRECTORY=internet-drafts Content-Transfer-Encoding: 7bit Content-Type: text/plain Content-ID: <2002-9-5121834.I-D@ietf.org> --==========01772099==========-- --==========01767743==========-- --==========01778822==========-- Envelope-to: ccamp-data@psg.com Delivery-date: Tue, 08 Oct 2002 14:43:53 -0700 Message-Id: <4.3.2.7.2.20021008172858.02f17120@mo-ex1> Date: Tue, 08 Oct 2002 17:38:18 -0400 To: ccamp@ops.ietf.org From: Lou Berger Subject: Fwd: Updated draft (draft-ietf-mpls-generalized-rsvp-te-09.txt) Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed The security section (sec. 12) of the gmpls-rsvp-te document has been updated per feedback from the IESG. There are no technical changes (just details added). With this change, there should be no issues remaining with the GMPLS signaling documents.

Date: Tue, 1 Oct 2002 19:11:58 -0700 Organization: NEC hi all, I have the following doubts, could u please explain me? If I am wrong with my assumptions please correct me. Assumptions : * In optical domain - control channel and data channel are separate. ISIS will be running in the control channel and advertise thecontrol channel connectivity. For GMPLS/TE purpose we r adding the data channel properties along with control channel properties in ISIS LSPs and flooding it. so i assume that we need not establish data channel adjacency in each and every data channel using hellos. Hellos will be exchanged only in control channel and control channel adjacency will be established. In LSPs along with control channel link state, data channel properties will be advertised. * we can have multiple data channels between two systems ( many point to point links ). for each link local end will assign local link identifer and remote end will assign remote link identifier. Doubts : >From ISIS GMPLS extension : * Section 6.5 says Link's local and remote identifers are exchanged using 3 way PP handshake. using 3 way PP Handshake, we can exchange local and remote identifiers. In this case it is done for the link where data and control channel are not separate. In optical domain since we exchange hellos only in control channel, how do we exchange link identifiers for so many data channels that are running between two machines. * SRLG option is unique for local and remote link identifier combination right?, if that is the case anyway we r advertising the local and remote idenitfier in IS extended reachability field as a sub TLV, so we can add SRLG as a sub TLV of IS extended reachability right? why do we need a separate TLV?( assumption : if we have n data links between two machines A and B, in A's LSP IS extended reachability for neighbour B, will appear n times for n different links ) thanks rams.
