Pseudo Wire Emulation Edge to Edge (pwe3) Thursday, November 21 at 1300-1500 ================================== CHAIR: Danny McPherson AGENDA: 1300-1310 Administrivia (10 minutes) Danny McPherson - Chair Agenda Bashing Minutes Blue Sheets WG Document Status 1310-1325 PWE3 Architecture Stewart Bryant http://www.ietf.org/internet-drafts/draft-ietf-pwe3-arch-01.txt http://www.ietf.org/internet-drafts/draft-bryant-pwe3-terms-01.txt Discussion: 1) Get confirmation that the group is happy with the PLD and framework merge. 2) Confirm that Ethernet emulation model is right following list discusions ongoing. 3) Terms documentation strategy (fold into arch) 4) Last call request which will be echoed on mailing list. 1325-1340 PPVPN L2 Signaling Eric Rosen http://www.ietf.org/internet-drafts/draft-rosen-ppvpn-l2-signaling-02.txt Discussion: Many of the L2VPN provisioning models being discussed in PPVPN can only be supported by "martini signaling" if the notion of "VCid" is generalized. The main issue to be discussed is the need for such generalization, and the secondary issue is the particular proposal for generalization. 1340-1350 PW Management Discussion "Thomas D. Nadeau" Discussion: MIB Update. Discuss MPLS management concerns. 1350-1400 PWE3 TDM Draft Shahram Davari http://www.ietf.org/internet-drafts/draft-davari-pwe3-aal12-over-psn-00.txt Discussion: 1) The scenarios that TDMoIP would be used, 2) The case that AAL1/2 is specially designed for TDM emulation 3) The case for interworking with existing ATM (AAL1) networks 4) The case for ease of implementing ASAP (Any Service Any Port) 1400-1410 Issues with Control Word & Packet Loss "Yaakov Stein" http://www.ietf.org/internet-drafts/draft-stein-pwe3-controlword-00.txt http://www.ietf.org/internet-drafts/draft-stein-pwe3-tdm-packetloss-00.txt Discussion: I would discuss draft-stein-pwe3-controlword-00.txt and quickly explain the present formats and propose that a single format be chosen. I'll also discuss draft-stein-pwe3-tdm-packetloss-00.txt and I will display a graph of voice quality vs packet loss and packet loss figures, and propose that any TDM draft be tolerant to 1 percent packet loss. 1410-1420 Bi-directional LSPs for classical MPLS Rohit Dube http://www.ietf.org/internet-drafts/draft-dube-bidirectional-lsp-00.txt Discussion: I plan to discuss the changes over regular MPLS needed to make bi-directional LSPs available to classical MPLS. 1420-1425 TDM Design Team Update/Discussion Tom K. Johnson Discussion: Intend to inform the WG about any agreements reached by the TDM DT prior to the WG meeting and answer any questions. 1425-1430 Unstructured TDM Sasha Vainshtein http://www.ietf.org/internet-drafts/draft-vainshtein-pwe3-ucesopsn-00.txt Discussion: This is a NEW draft. Hence I plan to discuss the motivation, basic approach, standard issues vs. local issues and the list of FFS issues. Also, perhaps the results of discussion in the TDM Design Team. 1430-1440 Header Compression Drafts "Ash, Gerald R (Jerry), ALASO" http://www.ietf.org/internet-drafts/draft-ash-e2e-vompls-hdr-compress-00.txt http://www.ietf.org/internet-drafts/draft-ash-e2e-crtp-hdr-compress-00.txt Discussion: I'm planning to discuss the following issues: a) PWE3 WG charter extension, b) protocol extensions for cRTP, RSVP-TE, RFC2547 VPNs, c) resynchronization, performance, and applicability of cRTP and 'simple' mechanisms, d) scalability of E2E VoMPLS applied CE-CE, and e) LDP application as the underlying LSP signaling mechanism. These issues have been further elaborated and discussed on the PWE3 mailing list. 1440-1445 SG13 Activities Regarding X-MPLS Interworking "Ghassem Koleyni" Discussion: I plan to tell them about progress in ATM-MPLS interworking and show them few encapsulation formats that we have agreed which is based pretty much like the draft that Luca has. 1445-1455 Draft Updates Luca Martini http://www.ietf.org/internet-drafts/draft-ietf-pwe3-control-protocol-01.txt Discussion: Changes from draft-martini. http://www.ietf.org/internet-drafts/draft-ietf-pwe3-ethernet-encap-01.txt Discussion: Updated Ethernet encapsulation employing only one mode. http://www.ietf.org/internet-drafts/draft-ietf-pwe3-atm-encap-00.txt Discussion: Merging of two proposed designs. 1455-1500 Wrap Up
