Here is a new version of the PCEP MIB. There have been a number of changes since the last revision. Here is a run-down of the most important ones.
1. The MIB is now read-only and is used to report status. I believe that this brings it in line with current practice for new MIBs. 2. There has been a structural change to the PCEP session MIB to reflect the possibility that two PCEP sessions may transiently exist between a pair of PCEP speakers, before one of the sessions reaches the 'up' state. This has been accommodated by adding a new index field "pcePcepSessInitiator" to the session MIB, indicating which side initiated the TCP connection. There is a simpler alternative, which is to ban sessions from appearing in this MIB until they are 'up', but I came down on the side of wanting to see all sessions in the MIB including those not yet established. 3. A load of statistics have been added to the peer and session MIBs. These are mostly counts of messages, requests, errors and so on. The values in the peer MIB track statistics across all sessions to a given peer, whereas the values in the session MIB track statistics for this session only. I decided that the possibility of short-lived sessions meant that we should have both sets of statistics available. However, this causes a high degree of duplication between the MIBs. Please let me have any comments, particularly if you disagree with any of directions we are .

This draft is a work item of the Path Computation Element Working Group of the IETF. Title : PCE communication protocol (PCEP) Management Information Base Author(s) : A S Kiran Koushik Stephan Emile Quintin Zhao Daniel King Jonathan Hardwick Filename : draft-ietf-pce-pcep-mib-04.txt Pages : 43 Date : 2013-02-19 Abstract: This memo defines an experimental portion of the Management Information Base for use with network management protocols in the Internet community. In particular, it describes managed objects for modeling of Path Computation Element communication Protocol (PCEP) for communications between a Path Computation Client (PCC) and a Path Computation Element (PCE), or between two PCEs.
