A DATA ACCESS, REPLICATION OR COMMUNICATION SYSTEM COMPRISING A MESSAGE QUEUING COMMUNICATIONS PLATFORM

摘要

The present invention envisages a data access, replication or communication system comprising a message queuing communications platform that enables delivery of a message over a network to be reliable, even if an unreliable transport protocol is used, in which the platform operates in a 'session independent' manner. It therefore challenges the orthodox bias in favour of session based systems. Session based systems tear down a session in various situations (e.g. when data transfer rates fall below a threshold or there is a period of inactivity (a timeout) or there is a change in PDP context such as switching from internet browsing to media messaging) and then initiate a new session. A 'session independent' platform however does not deliberately tear down a connection if data rates fall because of network performance in order to re-establish a new session with better performance.
