WebbLike TCP, SCTP provides reliability, sequencing, flow control, and full-duplex data transfer. Unlike TCP, SCTP provides: Association instead of "connection": An association refers to a communication between two systems, which may involve more than two addresses due to multihoming. Message-oriented: provides sequenced delivery of individual records. Webbone SCTP stream, and the SCTP association/stream should not be changed during the communication of the UE-associated signalling unless TNL binding update is performed. Transport network redundancy may be achieved by SCTP multi-homing between two end-points, of which one or both is assigned with multiple IP addresses.
