I installed FreeBSD-v5 on my machine. It sounds that that didnot includes UDP-lite, I also checked the IPv6 package of 5-current version. It should be there are some specification for describing how to use UDP-lite to generate a UDP-lite socket. I am sure UDP-lite or similar protocol for future video communication is very useful. And I want to build a testbed for that. I also read some papers about the using of UDP-lite. BUT a little difficulty to get UDP-lite using information. It is most appreciated that if you or anyone can give me any hint about it.
