Dear RTGWG folks,

We have submitted a draft ” draft-xu-rtgwg-monitoring-neighbor-state-00” that describes the motivation of monitoring protocol neighboring state. The link state and protocol neighbor state changes are essential information for both path protection and route optimization. Although there exist methods for collecting such information, such as BFD state for ISIS/OSPF, the performance of the current export approach is not quite satisfying (i.e., by SNMP trap). The time latency of using SNMP can cause the miss of real-time process of such event (neighboring state automatically recovered within 1-2 secs).

We think it can be meaningful to have a light-weight information collection and export approach that can cover various protocols, so that the neighbor state change can be detected and reacted to quickly enough at the server side (possibly combined with the high-priority processing of such data at the server side). We also mentioned some potential solution options in the draft.

Please feel free to let us know if you have any comment or suggestion on either the motivation or the solution.

Abstract:

   Various protocols are deployed in today's networks, such as BGP /

   ISIS / OSPF etc.  Link neighbor state changes and protocol neighbor

   state changes are the most important network events that need to be

   processed with the highest priority.  In particular, the SDN

   controller needs to quickly sense the link neighbor & protocol

   neighbor state change information in the network.  Thus, the various

   policies applied by the SDN controller to the network can quickly

   match the current state of the network.  This document discusses some

   possible scenarios and the relevant requirements.

Oliver.
