What is SIGTRAN?
2
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.
3
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.
4
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.
5
SIGTRAN & Gateways SCTP supports node-to-node transport of SS7/ISDN traffic between Signaling Gateways (SGs)/Media Gateways (MGs) and Media Gateway Controllers (MGCs).
6
SCTP Associations Stream Control Transmission Protocol works on the basic concept of associations and streams.
7
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
