Body |
The CCAMP Working Group of the IETF thanks you for sharing your OTNT Work Plan and for soliciting our comments. We have the following two points that you may want to use to update your document. 1. Table 5-1 This table lists standardisation activities for carrier- class Ethernet in various SDOs. The CCAMP working group has the responsibility within the IETF for developing common control plane and measurement plane solutions for use within transport networks, and layer 2 (for example, Ethernet) is within scope for our work. The working group has been discussing the application of GMPLS protocols to the dynamic control of Ethernet networks with the following results: a. draft-ietf-ccamp-ethernet-traffic-parameters-01.txt This Internet-Draft documents extensions to the RSVP-TE signaling protocol to express Ethernet traffic parameters so that GMPLS can be used to set up Ethernet LSPs and to request Ethernet services at a GMPLS UNI. The draft can be found at http://www.ietf.org/internet-drafts/ draft-ietf-ccamp-ethernet-traffic-parameters-01.txt b. GMPLS Ethernet Label Switching (GELS) The GELS effort is intended to develop a single set of protocol extensions that are applicable to the establishment of LSPs through an Ethernet network. Currently there are several proposals of what type of Ethernet network may benefit from this type of control plane, and the appropriateness of each proposed data plane will be verified with the IEEE before CCAMP attempts to apply a control plane. Currently there are several individual submission Internet-Drafts that have started to lay out the requirements and potential solutions for the GMPLS protocol extensions. 2. Table 7-1 Table 7-1 provides a long list of related OTNT industry standards and specifications. a. GMPLS and Optical-Related RFCs We would like to suggest some additions to this list from the IETF as follows: RFC 3471 : Generalized Multi-Protocol Label Switching (GMPLS) Signaling Functional Description RFC 3473 : Generalized Multi-Protocol Label Switching (GMPLS)Signaling Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) Extensions RFC 4652 : Evaluation of Existing Routing Protocols against Automatic Switched Optical Network (ASON) Routing Requirements RFC 4726 : A Framework for Inter-Domain Multiprotocol Label Switching Traffic Engineering RFC 4736 : Reoptimization of Multiprotocol Label Switching (MPLS) Traffic Engineering (TE) Loosely Routed Label Switch Path (LSP) RFC 4783 : GMPLS - Communication of Alarm Information RFC 4801 : Definitions of Textual Conventions for Generalized Multiprotocol Label Switching (GMPLS) Management RFC 4802 : Generalized Multiprotocol Label Switching (GMPLS) Traffic Engineering Management Information Base RFC 4803 : Generalized Multiprotocol Label Switching (GMPLS)Label Switching Router (LSR) Management Information Base RFC 4874 : Exclude Routes - Extension to Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) The latest list of CCAMP RFCs can be found at the CCAMP Charter page, http://www.ietf.org/html.charters/ccamp-charter.html A further short list of RFCs have been assigned numbers and will be published in the next few days: RFC 4872 : RSVP-TE Extensions in Support of End-to-End Generalized Multi-Protocol Label Switching (GMPLS) Recovery RFC 4873 : GMPLS Segment Recovery b. GMPLS and Optical-Related Internet-Drafts We welcome your listing of Internet-Drafts for related work. We make the following observations: i. All Internet-Drafts should be identified as "work in progress". This request is made, as standard, by the IETF in the following boilerplate text at the head of every Internet-Draft... Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." ii. The following Internet-Drafts in Table 7-1 have been replaced with RFCs as listed above: draft-ietf-ccamp-gmpls-tc-mib draft-ietf-ccamp-gmpls-te-mib draft-ietf-ccamp-gmpls-lsr-mib draft-ietf-ccamp-rsvp-te-exclude-route draft-ietf-ccamp-gmpls-alarm-spec draft-ietf-ccamp-inter-domain-framework draft-ietf-ccamp-loose-path-reopt draft-ietf-ccamp-gmpls-ason-routing-eval iii. Additional Internet-Drafts You may wish to list the following CCAMP Internet- Drafts as relevant to your work: draft-ietf-ccamp-inter-domain-rsvp-te-05.txt Inter domain Multiprotocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering - RSVP-TE extensions draft-ietf-ccamp-lsp-stitching-05.txt Label Switched Path Stitching with Generalized Multiprotocol Label Switching Traffic Engineering (GMPLS TE) draft-ietf-ccamp-gmpls-rsvp-te-call-04.txt Generalized MPLS (GMPLS) RSVP-TE Signaling Extensions in support of Calls draft-ietf-ccamp-lsp-hierarchy-bis-01.txt Procedures for Dynamically Signaled Hierarchical Label Switched Paths draft-ietf-ccamp-mpls-gmpls-interwork-fmwk-02.txt Framework for MPLS-TE to GMPLS migration draft-ietf-ccamp-ethernet-traffic-parameters-01.txt MEF Ethernet Traffic Parameters draft-ietf-ccamp-gmpls-ason-routing-ospf-03.txt OSPFv2 Routing Protocols Extensions for ASON Routing draft-ietf-ccamp-mpls-graceful-shutdown-02.txt Graceful Shutdown in GMPLS Traffic Engineering Networks draft-ietf-ccamp-gmpls-vcat-lcas-02.txt Operating Virtual Concatenation (VCAT) and the Link Capacity Adjustment Scheme (LCAS) with Generalized Multi-Protocol Label Switching (GMPLS) draft-ietf-ccamp-gmpls-ted-mib-01.txt Traffic Engineering Database Management Information Base in support of GMPLS draft-ietf-ccamp-pc-and-sc-reqs-00.txt Requirements for the Conversion Between Permanent Connections and Switched Connections in a Generalized Multiprotocol Label Switching (GMPLS) Network draft-ietf-ccamp-mpls-gmpls-interwork-reqts-00.txt Interworking Requirements to Support operation of MPLS-TE over GMPLS networks draft-ietf-ccamp-inter-domain-recovery-analysis-00.txt Analysis of Inter-domain Label Switched Path (LSP) Recovery The latest list of CCAMP Internet-Drafts can be found at the CCAMP Charter page, http://www.ietf.org/html.charters/ccamp-charter.html iv. Expired Internet-Drafts The following Internet-Drafts listed in table 7-1 have expired and are not being pursued. draft-ietf-ipo-impairments draft-ietf-ipo-framework c. Path Computation-related RFCs and Internet-Drafts In the light of G.7715.2, you may also be interested in including the Path Computation Element (PCE) RFCs and Internet-Drafts within table 7-1 as follows: RFC 4655 : A Path Computation Element (PCE) Based Architecture RFC 4657 : Path Computation Element (PCE) Communication Protocol Generic Requirements RFC 4674 : Requirements for Path Computation Element (PCE) Discovery draft-ietf-pce-pcep-07.txt Path Computation Element (PCE) communication Protocol (PCEP) draft-ietf-pce-inter-layer-req-04.txt PCC-PCE Communication Requirements for Inter-Layer Traffic Engineering draft-ietf-pce-pcecp-interarea-reqs-05.txt PCE Communication Protocol (PCECP) Specific Requirements for Inter-Area Multi Protocol Label Switching (MPLS) and Generalized MPLS (GMPLS) Traffic Engineering draft-ietf-pce-inter-layer-frwk-03.txt Framework for PCE-Based Inter-Layer MPLS and GMPLS Traffic Engineering draft-ietf-pce-policy-enabled-path-comp-01.txt Policy-Enabled Path Computation Framework draft-ietf-pce-interas-pcecp-reqs-01.txt Inter-AS Requirements for the Path Computation Element Communication Protocol (PCECP) draft-ietf-pce-brpc-04.txt A Backward Recursive PCE-based Computation (BRPC) procedure to compute shortest inter-domain Traffic Engineering Label Switched Paths draft-ietf-pce-disco-proto-ospf-03.txt OSPF protocol extensions for Path Computation Element (PCE) Discovery draft-ietf-pce-disco-proto-isis-03.txt IS-IS protocol extensions for Path Computation Element (PCE) Discovery draft-ietf-pce-disc-mib-01.txt Definitions of Managed Objects for Path Computation Element Discovery draft-ietf-pce-tc-mib-01.txt Definitions of Textual Conventions for Path Computation Element draft-ietf-pce-pcep-xro-00.txt Extensions to the Path Computation Element Communication Protocol (PCEP) for Route Exclusions The latest list of PCE RFCs and Internet-Drafts can be found at the PCE Charter page, http://www.ietf.org/html.charters/pce-charter.html d. Obsoleted specification Please note that RFC 4327 has been obsoleted by RFC 4631 and should no longer be listed in its own right. e. MPLS and Packet-related RFCs and Internet-Drafts We suggest that in the light of the recent work within the ITU-T related to packet transport networks including, but not limited to, pseudowires and T-MPLS, you may wish to contact Mr. Loa Andersson who is IETF liaison to the ITU-T on MPLS to see what new and relevant MPLS RFCs and Internet-Drafts have been published.
