Dear all, This is to solicit your input on the new draft "Relayed CSPF for Multi-Area Multi-AS PCE".
For LSPs that span across multiple areas or multiple autonomous systems (AS), the path computation element (PCE) in each area or each AS can cooperate and conclude the optimal results if so exist. An upstream PCE, though incapable to carry out the path computation for the tailend outside of its domain, can provide the history of the computation to its downstream PCEs which will assume the computation job till it is accomplished or relay the baton to the next runner. We will have a presentation on Thursday 11/11/2010 PCE WG meeting. Please find the draft at http://tools.ietf.org/html/draft-lu-relayed-cspf-00 Your review and comments are greatly appreciated. Thank you, -wenhu
