Introduction to Stream Control Transmission Protocol

The first in a series on SCTP and how to migrate TCP applications.

SCTP has full support out of the box for IPv6 as well as IPv4. You simply need to use IPv6 socket addresses instead of IPv4 socket addresses. If you create an IPv4 socket, SCTP will deal only with IPv4 addresses. But, if you create an IPv6 socket, SCTP will handle both IPv4 and IPv6 addresses.


This article provides a brief introduction to the IETF Stream Control Transmission Protocol and explains how it can be used as a replacement for TCP. In future articles, we will examine additional features of SCTP and show their use.
