A method of controlling a local process that forms part of a first processing entity, where the first processing entity maintains a plurality of associations with a plurality of remote processes in a second processing entity, comprises receiving a failure message from a remote process indicating a fault affecting an association linking the local process with that remote process; queueing data messages destined for that remote process; controlling the transmission of an acknowledgement of the failure message so that data messages pending on the association are received at that remote process before the acknowledgment of the failure message; and initiating a traffic diversion to set up an alternate path between the first processing entity and the second processing entity for queued data messages.

Methods and apparatus for controlling processing entities, such as distributed signalling gateways

A signalling gateway for connecting a first network to a second network, the signalling gateway being operable to, receive a signalling message from the first network, the message comprising destination information, read the destination information and, where the destination information corresponds to a predetermined value, forward the message to one of a first entity on the first network and a second entity on the second network in accordance with a distribution rule.

Systems and methods for a signalling gateway for connecting networks

A method of providing a routing key interpreter for a signalling gateway, the method comprising the steps of generating an input file comprising a plurality of input expressions and a plurality of routing keys corresponding to the input expression, supplying the input file to a lexical analyser generator to generate a lexical analyser, and implementing the routing key interpreter using the lexical analyser.
