Research feature - SCTP: a proposed standard for robust internet data transport

Abstract

The stream control transmission protocol is a new standard for generalpurpose transport proposed by the Internet Engineering Task Force. SCTP addresses application and security gaps left open by its predecessors, TCP and UDP.

Retransmission policies for multihomed transport protocols

“…We evaluate the retransmission policies using University of Delaware's SCTP module [8] for the ns-2 network simulator [3]. Fig.…”

“…Two recent transport layer protocols, the Stream Control Transmission Protocol (SCTP) [23,9] and the Datagram Congestion Control Protocol (DCCP) [18] support multihoming at the transport layer. The motivation for multihoming in DCCP is mobility [17], while SCTP is driven by a broader and more generic application base-fault tolerance.…”

Managing PI-resources in 4G wireless systems: the opportunistic way

“…This implies short handover times; integration of authentication, authorization and accounting (AAA) procedures to allow for one-time sign in; and mobility management. The fact that the UE has several IP addresses (at least one per RAN) introduces a problem different from the multi-homing [3] or the multi-connection [4] problems. These latter problems are mainly related with redundancy of networks connections and the choice of network paths are mainly done by the network without any intervention of the applications.…”

SCTP-PF: A Quick Failover Algorithm for the Stream Control Transmission Protocol

“…With the procedures specified in [RFC4960], SCTP will (after a failover from the primary path) switch back to use the primary path for data transfer as soon as this path becomes available again. From a performance perspective, such a forced switchback of the data transmission path can be suboptimal as the Congestion Window (CWND) towards the original primary destination address has to be rebuilt once data transfer resumes, [CARO02]. As an optional alternative to the switchback operation of [RFC4960], this document specifies an alternative Primary Path Switchover procedure that avoids such forced switchbacks of the data transfer path.…”
