What is SIGTRAN?

SIGTRAN Signaling Transport (SIGTRAN) is an Internet Engineering Task Force (IETF) standard for transporting Public-Switched Telephone Network (PSTN) Signaling System 7 (SS7) traffic over IP networks.

SCTP in SIGTRAN SIGTRAN's transport protocol, Stream Control Transmission Protocol (SCTP), allows carriers to use the IP infrastructure to transport SS7 telephony traffic over an IP network.

Interoperability The generic design of SCTP provides a reliable transport delivery mechanism for various multimedia and wireless frameworks such as H.323, MGCP, H.248/MEGACO, SIP and 3G.

SIGTRAN & Gateways SCTP supports node-to-node transport of SS7/ISDN traffic between Signaling Gateways (SGs)/Media Gateways (MGs) and Media Gateway Controllers (MGCs).

SCTP Associations Stream Control Transmission Protocol works on the basic concept of associations and streams.

An SCTP Association: is similar to a TCP connection supports multiple IP addresses at either or both ends (multi-homing) supports multiple logical streams (multi- streaming) provides sequenced delivery for user datagrams within a single stream
