SCTP Analysis
The SCTP analysis module collects information on the chunk type found in SCTP (Stream Control Transmission Protocol) headers and posts this information to the Summary column of the Packets view of capture windows.
SCTP (rfc 2960) provides reliable simultaneous transmission of multiple data streams between two nodes on an IP network. Either or both of the end points may be multi-homed. The original purpose of SCTP was to make IP networks capable of establishing the types of connections required for telephone service. Telephone service relies on SS7 (Signalling System 7), which sends signalling information (that is, information about the connection) along with the voice or other data at the same time. Sometimes referred to as next generation TCP (TCPng), SCTP was designed for broad application, and is not limited to telephone service over IP.
