Hi,PCEers: Here is the update of DNS based PCE discovery draft (http://tools.ietf.org/html/draft-wu-pce-dns-pce-discovery-03) based on a few discussion on the list and WG discussion during Berlin meeting.
The main changes comparing to the previous version are: 1.Provide both general query and capability DNS query by extending S-NAPTR. Capability DNS query is discovery of PCE supporting specific capabilities. 2.Provide data format in TXT record used for storing additional PCE information. 3.Link PCE domain with DNS domain name to allow a NAPTR query for a server in a PCE domain associated with DNS domain-name, e.g., discover PCE server in a specific PCE domain. The diff is: http://www.ietf.org/rfcdiff?url2=draft-wu-pce-dns-pce-discovery-03 Dan: Please check if comments you raised on the list are addressed.

Title : Path Computation Element (PCE) Discovery using Domain Name System(DNS) Author(s) : Qin Wu Dhruv Dhody Daniel King Diego R. Lopez Filename : draft-wu-pce-dns-pce-discovery-03.txt Pages : 23 Date : 2013-10-10 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 type and capability discovery via DNS.
