Here are some comments from my review as AD that need to get handled as part of IETF last call. Thanks, Adrian === Could you expand "p2p" where it is first used? --- The very first sentence is hard to parse MPLS transport networks can be characterized as being a network of connections between nodes within a mesh of nodes and the links between them. Maybe try The MPLS Transport Profile (MPLS-TP) provides tools to construct and operate a set of connections between nodes in an MPLS network. The MPLS network is a mesh comprising nodes and the links between them. --- I understand that you want to use RFC 2119 language to clarify the requirements, but RFC 2119 was developed for specifying protocols, so the direct reference and boilerplate quote is incongruous. I suggest you use the language as found in RFC 5654, viz.: The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. Although this document is not a protocol specification, the use of this language clarifies the instructions to protocol designers producing solutions that satisfy the requirements set out in this document. --- In Section 5.1 you have the control protocol SHOULD NOT be used as the primary resilience mechanism. I agree, but I think that the term "primary resilience mechanism" may be under defined. Can you do anything to clarify this? Maybe... the control protocol SHOULD NOT be used as the primary mechanism for detecting or reporting network failures, or for initiating or coordinating protection switch-over. That is, it SHOULD NOT be used as the primary resilience mechanism. > -----Original Message----- > From: mpls [mailto:mpls-bounces@xxxxxxxx] On Behalf Of The IESG > Sent: 09 June 2014 15:10 > To: IETF-Announce > Cc: mpls@xxxxxxxx > Subject: [mpls] Last Call: <draft-ietf-mpls-smp-requirements-05.txt> > (Requirements for MPLS-TP Shared Mesh Protection) to Informational RFC > > The IESG has received a request from the Multiprotocol Label Switching WG > (mpls) to consider the following document: > - 'Requirements for MPLS-TP Shared Mesh Protection' > <draft-ietf-mpls-smp-requirements-05.txt> as Informational RFC > > The IESG plans to make a decision in the next few weeks, and solicits > final comments on this action.
