SCTP protocol in Mobile Networks
SCTP (Stream Control Transmission Protocol) is a transport layer protocol that is an alternative to TCP (Transmission Control Protocol) and UDP (User Datagram Protocol). It can provide reliable, message-oriented communication, with support for multi-homing.
SCTP is widely used as the transport protocol for signalling in mobile networks. As its multi-homing capabilities, allow mobile network elements to have multiple IP addresses. This enables load balancing, and provides redundancy in case of network or device failures.
