Stream Control Transmission Protocol (SCTP) Associations

 in
This second in a series of articles on the SCTP network protocol examines associations and connections.
Conclusion

This article has discussed a feature novel to SCTP, streams. A stream allows multiple data channels on a single association. This avoids a major problem of TCP, head-of-line blocking, but it also allows applications that deal with multiple logical streams to be written more easily. The next and final article will look at how SCTP can handle multiple associations at once, simplifying the TCP model and also offering improvements over the UDP connection model.
