Correlating and Load Balancing IMS Traffic in a Visibility Network

Techniques for correlating and load balancing IMS traffic in a visibility network are provided. According to one set of embodiments, a packet broker of the visibility network can receive IMS traffic replicated from an IMS core network and identify control/data packets in the IMS traffic that are part of the same IMS session based on FROM and TO user identities included in the packets. The packet broker can then generate a unique session identifier for the IMS session and add the generated session identifier to the packets. In certain embodiments, the packet broker can further provide the generated session identifier as input to a load balancing algorithm or rule set. The load balancing algorithm or rule set can output an egress port of the packet broker through which the control/data packets should be forwarded based on the session identifier.
