Hi, all: Here is the update of DNS based PCE Discovery draft based on JP's comments raised in the last IETF meeting. The diff is: http://www.ietf.org/rfcdiff?url2=draft-wu-pce-dns-pce-discovery-06 In this version (v-06), we consolidate motivation section and introduce data center related use case to point out three issues in the existing mechanisms a. load balancing issue in multiple PCE instances b. security issue in the inter-domain communication c. handling changes in PCE identities or failure event coping. In section 3.4, we use additional texts to clarify how DNS based mechanism address these issues.

Title : Path Computation Element (PCE) Discovery using Domain Name System(DNS) Authors : Qin Wu Dhruv Dhody Daniel King Diego R. Lopez Jeff Tantsura Filename : draft-wu-pce-dns-pce-discovery-06.txt Pages : 23 Date : 2014-05-08 Abstract: Discovery of the Path Computation Element (PCE) within an IGP area or routing domain is possible using OSPF [RFC5088] and IS-IS [RFC5089]. However, it has been established that in certain deployment scenarios PCEs may not wish, or be able to participate within the IGP process. In those scenarios, it is beneficial for the Path Computation Client (PCC) (or other PCE) to discover PCEs via an alternative mechanism to those proposed in [RFC5088] and [RFC5089]. This document specifies the requirements, use cases, procedures and extensions to support PCE discovery along with certain relevant information type and capability discovery via DNS.
