Hi,

Did you consider fault-tolerant TCP/IP connections to multiple servers?i was thinking about implementing Robust TCP/IP connections .. but somebody told me that is not very consistent , and i think so also ,
See these : This one is heavy-weight, whole process wrapping etc. Also the implementation is on Linux. Engineering fault-tolerant TCP/IP servers using FT-TCP. D. Zagorodnov, K. Marzullo, L. Alvisi, and T.C. Bressoud. In Proc. IEEE Intl. Conf. on Dependable Systems and Networks (DSN),

This one is lightweight(in place logging), works for TCP/IP and for pipes and the implementation is on FreeBSD. Service Continuations: An Operating System Mechanism for Dynamic Migration of Internet Service Sessions. F. Sultan, A. Bohra, L. Iftode.

I did not know of them.
Thanks!

Cheers Aniruddha
This would make it very easy to implement fault-tolerant systems with FreeBSD if the communication is TCP/IP based.
