Introducing effect of different factors on Multi-homing Abstract
The main purpose of designing the Stream Control Protocol (SCTP) was to offer a robust transfer of traffic between the hosts over the networks. For this reason SCTP multi-homing feature was designed, in which an SCTP sender can access destination host with multiple IP addresses in the same session. If the primary path between the source and the destination is down, the traffic may still be sent to the destination by utilizing redundant path. And SCTP multi-homing also supports for the concurrent multipath transfer of traffic. This paper introduces the effect of different network factors like concurrent cross traffic, congestion control algorithms and SACK timers on multi-homing feature of SCTP. Throughput and end-to-end packet delay were used as performance metrics to introduce the effect of these factors. From the study it was introduced that concurrent cross traffic in the network behaves same on multi-homed interfaces and both interfaces were affected almost same. It was concluded that congestion control algorithms also affects on multi-homing, the RED congestion control algorithm reduced delay and improved throughput of the SCTP multi-homing. In RFC4960 recommended SACK timer is 200ms, but when 100ms SACK timer was used with concurrent multipath transfer in SCTP (CMT-SCTP) multi-homing, the high throughput and low delay was achieved as compared with 200ms and 300ms, which indicated that different SACK timers affects on multi-homing feature of SCTP. All the simulation works have been conducted in NS2 network simulator.
