Re: [PCE] About ASBR locate

[ZhangRenhai <[e-mail]>]

HI, Vijay

 

As you said,  the prime thought for this draft is to find out the
connectivity of the ASBRs, this information can be used for inter-AS TE, for
example, if an ERO contained an AS number as its next hop, how to discover
the tail end of the route segment in local AS for the inter-as TE lsp
computation.

 

I can fold your thought in future version

Mach,
A question regarding your I-D.

 

The mechanism you described only finds out the connectivity of the ASBRs. It
does not discover the TE characteristics of the inter-AS links, for ex. the
link bandwidth, colour etc. which may be needed to decide if an inter-AS
link can be used for TE paths.  


Regards,


Vijay

Hi folks,

 

We have posted a new I-D which is about how to get the ASBR info which are
used to compute TE LSP in an Inter-AS scenario.

 

Any feed-back and comments would be most welcome!

 

Best regards,

 

Mach

A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
 
 
  Title                : Locate ASBR in PCE 
  Author(s)          : R. Zhang, M. Chen
  Filename : draft-zhang-pce-locate-asbr-00.txt
  Pages              : 8
  Date                : 2006-10-12
  
   The ability to compute constrained shortest Traffic Engineering (TE) 
   Label Switched Paths (LSPs) in Multiprotocol Label Switching (MPLS) 
   and Generalized MPLS (GMPLS) networks across multiple domains has 
   been identified as a key requirement. This document specifies a 
   procedure for an inter-AS PCE to locate boundary node within its 
   domain dynamically, which is used for path computation.

  exhibit different behavior, especially when dealing with
  "multipart" MIME messages (i.e. documents which have been split
