Tperf version 1.5 now supports UDP multicasting. In UDP multicast mode, each sender process sends datagrams to multiple hosts in specified order. On receiver side, each receiver process automatically multiplexes UDP streams from multiple processes.
Tperf is a very simple TCP/UDP bandwidth measurement tool written in standard C and UNIX socket API. It reports bandwidth on both of sender side and receiver side, UDP datagram loss statistics, etc.
