Summary for Sub-IP Area

Summary

   This document describes a mechanism that helps to minimize the
   negative effects on MPLS traffic caused by LSR's control plane
   restart, and specifically by the restart of its RSVP-TE component, on
   LSRs that are capable of preserving the MPLS forwarding component
   across the restart.

   This document also describes a mechanism that helps to minimize the
   negative effects on MPLS traffic caused by the disruption of the
   communication channel that is used to exchange RSVP messages between
   a pair of LSR, when the communication channel is separate from the
   channels carrying the actual LSPs, and the channels carrying the
   actual LSPs are not disrupted.

Where does it fit in the Picture of the Sub-IP Work

   This work fits squarely in either MPLS or CCAMP box.

Why is it Targeted at this WG

   The RSVP TE is a product of the MPLS WG. This document specifies
   procedures to minimize the negative effects caused by either restart
   of RSVP TE module of the control plane, or by a temporary failure of
   communication channel used to exchange RSVP messages between a pair
   of LSRs. Since the procedures described in this document are directly
   related to RSVP TE, it would be logical to target this document at
   the MPLS WG.

   At the same time, since the procedures described in this document use
   one of the RSVP objects defined in Generalized MPLS Signaling, and
   since Generalized MPLS Signaling belongs to CCAMP, one could also say
   that this document could be targeted at the CCAMP WG.

Justification

   The WG should consider this document, as it allows to minimize the
   negative effects caused by either restart of RSVP TE module of the
   control plane, or by a temporary failure of communication channel
   used to exchange RSVP messages between a pair of LSRs.
