Performance evaluation of the simple control transmission protocol (SCTP)

A new protocol which could be used for the transport of telecommunication signalling messages over an IP-based network is currently being discussed within the IETF. The protocol is called stream control transmission protocol (SCTP). We describe SCTP and an implementation of SCTP. Furthermore, we evaluate how the protocol performs in a wide area network, especially when competing with TCP. The results were obtained in a test-bed consisting of two local networks which are interconnected via an emulator of a wide area network.
