An Optimized Congestion Control and Path Management Scheme for SCTP
نویسندگان
چکیده
In this paper, a new SCTP congestion control mechanism is introduced in multi-homing mode. Congestion in each route can be avoided or can be controlled, based on an Active Queue Management (AQM) method. Also, routers compute probability of congestion for the sources on the paths and then notify them. Therefore, the sources can adjust their sending rates on each path effectively and if necessary, can switch to an alternate path to prevent congestion. Simulations have been conducted with Opnet linked with MATLAB. The simulation shows that the new method can decrease packet loss, increase the amount of transmissions and stabilize queue length, as compared with standard SCTP.

An Adaptive SCTP Congestion Control Scheme Based on Receiver Available Bandwidth Estimation
Streaming control transmission protocol (SCTP) is one kind of new generation transport layer protocol, is a little modification form TCP. Like TCP, the congestion control mechanism of current SCTP relies on packet loss as an indicator of network congestion. When congestion been detected the sender will reduce congestion window size to half to avoid congestion. In wire/wireless network environme...

Stream Control Transmission Protocol (SCTP) is newly emerged protocol, which combined good qualities of TCP and UDP. It is a reliable message oriented protocol providing Multistreaming and Multihoming as well. The congestion control scheme of SCTP is more or less similar to that of TCP with the exception of the Fast Recovery algorithm. The performance of SCTP over the Internet and satellite lin...
متن کاملTheoretical Analysis of an Ideal Startup Scheme in Multihomed SCTP
SCTP congestion control includes the slow start mechanism to probe the network for available bandwidth. In case of path swap in a multihomed association, this mechanism may cause a sudden drop in throughput and increased message delays. By estimating the available bandwidth on the alternate path it is possible to utilize a more efficient startup scheme. In this paper, we analytically compare an...

The currently rather heterogeneous wireless landscape makes handover between different network technologies, so-called vertical handover, a key to a continued success for wireless Internet access. Recently, an extension to the Stream Control Transmission Protocol (SCTP) – the Dynamic Address Reconfiguration (DAR) extension – was standardized by IETF. This extension enables the use of SCTP for v...
