<p>A method and server system providing overload control in application layer session routing. A centralised server system 12, 18 is arranged to monitor overload restriction requirements of session control nodes 21A-D within a large VoIP and Multimedia network 20 in order to handle session set-up requests. An overload status module 38 in the server system receives overload status messages 22 from the session control nodes and based on these messages and the demand on each destination session control node derived from session routing requests, the server system 12, 18 selects which session control nodes 21A-D as well as which of their associated interconnects to other networks to include in a routing response 6 to a routing request 5 from a source session control node 21A-D.</p> |
