Multipath state aware CMT using redundant transmission for SCTP multi homed hosts

Abstract

Advancement in networking technology has made it possible to transmit multimedia data in wired as well as wireless environments While the development of the Stream Control Transmission Protocol was directly motivated by the transportation of the Public Switched Telephone Network signaling messages across the Internet Protocol network SIGTRAN ensured that the design is also a good match for other applications with similar requirements The SCTP is a general purpose transport layer protocol for IP network data communications serving in a role analogous to the common protocols Transmission Control Protocol and User Datagram Protocol Two new major capabilities are designed into the SCTP the support for multihomed hosts and the support for multiple streams in a single SCTP association The built in support for multi homed hosts allows a single SCTP association to run across multiple links paths to achieve link path redundancy With this capability an SCTP association can be made to achieve fast failover from one link or path to another with little interruption to the data transfer service Multihomed SCTP end points might be less affected by network reconvergence because the lost packets are retransmitted to an alternative address The primary purpose of the SCTP is to provide a reliable end to end message transportation service over IP based networks The SCTP exploits the multihoming feature through newline
