Abstract

A system and method for handling network overload includes receiving one or more requests, wherein an originating client originates the one or more requests. It is determined if a network element handling the one or more requests is overloaded. If the network element is overloaded, a pushback message associated with a specific request of the one or more requests is generated. The pushback message is sent to the originating client.
