Abstract

Communications networks are evolving towards a scenario where there is a pervasive deployment of end user nodes capable of accessing multiple underlying networks concurrently. Concurrent access to multiple, often diverse, networks within a single end-to-end association is known as multi-homing. Through the use of multi-homing end user nodes have the potential to overcome many of the limitations caused by unreliable or incorrectly dimensioned communications networks. Such a technology is particularly required when supporting bandwidth intensive eLearning sessions which employ multi-media streaming technologies. The integrity of multimedia streams can be significantly improved when utilising a multi-homed transport protocol such as the Stream Control Transmission Protocol (SCTP) which facilitates path handover in the event of network failure. This paper investigates the effectiveness of SCTP to support multimedia streaming eLearning applications, such as Centra Symposium, in the situation where an underlying network suffers catastrophic network failure as a result of, for example, inappropriate network dimensioning. The results presented indicate that a multimedia stream received by an end user node that experiences a catastrophic network failure during transmission has comparable quality to a multimedia stream received by an end user node that did not experience network failure during transmission.
