Re: [mpls] Last Call: <draft-ietf-mpls-tp-shared-ring-protection-05.txt> (Shared-Ring protection (MSRP) mechanism for ring topology) to Proposed Standard

Dear authors,

I have two comments on this draft.

1) Section 4.4.1 (last two paragraphs above Figure 11)

Following two sentences are duplicated in the last two paragraphs above Figure 11.

Figure 11 shows the topology of single-node interconnected
rings. Node C is the interconnection node between Ring1 and
Ring2.

Proposed change: delete the last paragraph.

2) Section 5.1.4.2 (3rd paragraph from the bottom)

The last two bullet items correspond to conditions which trigger state transition from the Switching state to the Idle state. However, current text above those bullet items is describing adversely.

Proposed change: 

OLD TEXT
In one of the following conditions, transition from the Idle state to
the Switching state MUST be triggered:

NEW TEXT
In one of the following conditions, transition from the Switching state to
the Idle state MUST be triggered:

Best regards,
Taesik

Subject: [mpls] Last Call: <draft-ietf-mpls-tp-shared-ring-protection-05.txt> (Shared-Ring protection (MSRP) mechanism for ring topology) to Proposed Standard

The IESG has received a request from the Multiprotocol Label Switching WG
(mpls) to consider the following document:
- 'Shared-Ring protection (MSRP) mechanism for ring topology'
  <draft-ietf-mpls-tp-shared-ring-protection-05.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-05-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting.

Abstract

   This document describes requirements, architecture and solutions for
   MPLS-TP Shared Ring Protection (MSRP) in a ring topology for point-
   to-point (P2P) services.  The MSRP mechanism is described to meet the
   ring protection requirements as described in RFC 5654.  This document
   defines the Ring Protection Switch (RPS) Protocol that is used to
   coordinate the protection behavior of the nodes on MPLS ring.
