A method and server system for providing application layer session routing based on network element availability. A server system 12, 18 is arranged to monitor the abilities of session control edge nodes 21A-D within a large VolP and Multimedia transit network 20 to handle session set-up requests. A status module 38 in the server system receives status messages 22, 24 from the edge nodes and based on these messages a selection and modification module 40, 41 selects which edge nodes 21A-D as well as which of their associated interconnects to other networks to include in a response 5 to a routing request 4 from a source node 21A-D. |
