Hello Krishna, I couldn't find any attachments in your previous emails regarding TCP Vs TIPC performance numbers. It would be interesting to look at the number.
Not sure whether tipc-discussion mailing list forwards the attachments or not. If possible could you please forward them and a description about the performance tests that you have conducted over your network. Thanks, Jaya. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, June 08, 2007 12:05 PM To: [email protected] Subject: tipc-discussion Digest, Vol 13, Issue 5 Send tipc-discussion mailing list submissions to [email protected] To subscribe or unsubscribe via the World Wide Web, visit https://lists.sourceforge.net/lists/listinfo/tipc-discussion or, via email, send a message with subject or body 'help' to [EMAIL PROTECTED] You can reach the person managing the list at [EMAIL PROTECTED] When replying, please edit your Subject line so it is more specific than "Re: Contents of tipc-discussion digest..."

We would be interested in understanding the performance roadmap as envisaged by the TIPC team. It would be of great help if you could specify a time frame, at the end of which, we can expect the improvements in the 4K+ range too.
