Hello, We are working on a program that sends UDP datagrams in a fast loop, using Debian Linux 3.0 (kernel 2.4.9-686-smp). The send() function does not block until it can send the datagram. Therefore the theorical throughput is very high (even higher than the physical network bandwidth), but most packets are lost. We would like to have a reasonable packet loss rate (although we need UDP and not TCP). Currently the only way to ensure the datagrams leave the host is to force the program to wait between two send() calls. Is there a way in Linux to make send() really block instead of dropping most datagrams ? Do you know other systems (*-BSD...) where send() behaves differently ?
