The IESG has approved the following document: - 'Application-aware Targeted LDP' (draft-ietf-mpls-app-aware-tldp-09.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-mpls-app-aware-tldp/ Technical Summary Some tLDP applications e.g. remote loop-free alternate (LFA) and BGP auto discovered pseudowires may establish a tLDP session to any LSR in a network. The LSR that initializes such a session has enough information to administratively control initiation of the session. The targetted LSR normally does not have the information necessary to control acceptance of the requested session. This document defines a mechanism to advertise and negotiate Targeted Applications Capability (TAC) during LDP session initialization. The targetted LSR is made aware of targeted applications through the TAC information. When this happens it can establish a limited number of tLDP sessions for certain applications. In addition, each targeted application is mapped to LDP Forwarding Equivalence Class (FEC) Elements to advertise only necessary LDP FEC-label bindings over the session. Working Group Summary The WG process for this document has been fairly normal, and the working agreed that this is a necessary extension to LDP for some applications. Discussion has been targeted on resolving a small number of outstanding issues. The consensus in the working was good. Document Quality We are aware of several intentions to implement this specification. An implementation poll has been sent to the working group and as further information is received, the write-up will be updated. No expert review outside the working group is necessary.
