A method of controlling traffic in an intelligent communications network having a distributed processing environment using software objects corresponding to respective components of the network, wherein each object is associated with a respective service element parameter (SEP) and writes its SEP to a SEP field of each generated request, together with, in the event that the request is generated in response to receipt at the object of a request sent from another object, the contents of the SEP field of the received request. While an object is in overload state it rejects newly received requests if the contents of their SEP fields are less than a threshold. If the object is already handling a request, a newly received request will take priority if it has a higher SEP value. The request which gives way may be rejected, or may have its processing suspended.
