Configuration of rules in a network visibility system

Abstract:

Aspects of the present disclosure enable a router controller to maintain a default rules table indicating allocation of internet protocol (IP) addresses (of general packet radio service (GPRS) tunneling protocol (GTP) packets) to respective output ports. In an embodiment, the router controller receives information indicating the respective tunnel endpoint IP addresses of a control session and a data session. The router controller is configured to determine whether such IP addresses of the control session and the data session(s) are allocated to the same output port. In response to the IP addresses of the control session and the data session not being allocated to the same output port, the router controller is configured to generate a dynamic rule to forward packets of both the control session and the data session to the same output port.
