ABSTRACT:
The present invention concerns load balancing for control plane traffic of a network element comprising multiple CPU nodes assigned to a common external IP address in a packet data enabled telecommunication network. IP messages addressed to the network element are received, and received IP messages comprising GTP-C messages are identified. A TEID-C value of a GTP-C message is identified and the GTP-C message is forwarded to a CPU node based on its identified TEID-C value, if its identified TEID-C value does not equal zero.
