Dear sir
 
 i am a M.Tech student of IIT, Kharagpur currently working on my thesis titled " Fault tolerant Real time Multicast communication using Core based Trees". During my literature survey and correspondence with Tony Ballardie i had come to know that work on CBT  have been stopped after year 2000 and PIM-SM implementation commercially by CISCO routers.
 
 I have certain doubts and would be very greatful if u can throw somee light on these issues.
 
(i)     Firstly in  PIM-SM what is the fault tolerant mechanism incorporated for RP, link and node failures. 
 
(ii)   Secondly in PIM-SM, shared tree mode the RP is functioning similar to a core in CBT. So the inherent disadvantages of core being the bottleneck, congestion towards the core and adnt he end-to-end delay is greatet thatn SPT's, how this has been overcome in PIM-SM.
 
(iii) In NS2.28 version the implementation of PIM-SM protocols does it correspond to the revised ietm draft of PIM-SM.
 
lastly i would like to know how the protocol implementation in NS2 can be modified to incorporate fault tolerance mechanisms and also is it possible to build a CBT protocol from BST implementaion of PIM-SM in NS2.28.

keenly awaiting ur reply
 
regards
 
Parthiban
