Sigtran extension for network management and association changeover.

Dear folks,

We submitted two drafts about the sigtran extension, 
Although the Sigtran WG has been concluded, I still would like to 
talk about these topics in sigtran list before the discussion in tsvwg list.

The drafts may be found by

Abstract: 
   Sigtran is widely applied in the telecommunication network but there 
   are still some issues. This document briefly describes some concerned 
   scenarios and presents the association changeover and Sigtran routing 
   management problems. The goal of this document is to analyse the 
   existing shortage of Sigtran and discuss the desirable improvements.

Abstract:
   Sigtran specifies association-level reliable transport for signaling 
   using SCTP, but in some scenarios a single association failure's 
   reliability mechanism is not sufficient to achieve telco reliability. 
   This document specifies procedures for an SCTP association changeover 
   solution which will enable applications to meet a higher degree of 
   availability. Two generic changeover solutions are presented in this 
   document. One is implemented inside the SCTP protocol stack and the 
   other requires SCTP and ULP to work in collaboration. 

These extensions are expected to improve the performance of sigtran 
network, especially for telecommunication network, what do you think
about them?

Any comments are appreciated!

Thanks and best regards
