The present invention provides a system and method for establishing a data
transmission rate in a communication network for data transmission from a
first communication module to a second communication module. Generally,
the method comprises: (a) reading at the first module a predetermined
data reception rate limit of the second module; and (b) for the data at
the first module to be transmitted to the second module, establishing a
first module data transmission rate in dependence upon the predetermined
data reception rate limit read in step (a).
