I have been looking RTP (A Transport Protocol for Real Time Applications-RFC1889- http://www.cs.columbia.edu/~hgs/rtp), is used to send data in one direction with no acknowledgment, this protocol is supported in the applications, these are coded to add and recognize a new 12 byte header of RTP in each UDP datagram. I think that is desirable a RTP implementation in kernel available for several applications or for better performance. This implementation could be following the principles of Netgraph, it is to say encapsulating RTP how a Netgraph node or nodes into the BSD kernel. This implementation have sense? It is not clear what exactly one would implement in the kernel. Thanks for your opinions and comments. +-------------------------------+ | YONNY CARDENAS B. | | Systems Engineer | | | | Student M.Sc. | | UNIVERSIDAD DE LOS ANDES | | | | | +-------------------------------+ UNIX is BSD, and FreeBSD is an advanced 4.4BSD __________________________________________________ Do You Yahoo!?
