MARKERS FOR COMMUNICATION SYSTEMS COMPRISING A PLURALITY OF SIP SERVERS

摘要

The invention relates to a communication system (S) capable of exchanging SIP signalling messages with a communication network (N), comprising a plurality of servers (S₁, S₂, S₃... S_n) for processing incoming messages (m_s) and generating outgoing messages, and a load distribution equipment (LB) for conveying an incoming message to a particular server according to load distribution rules (R, R_aff). The servers are provided with means for including a marker into the outgoing messages that is at least representative of itself, and the load distribution rules of the load distribution equipment include rules (R) for conveying an incoming message containing a marker to the server corresponding to that marker.
