Abstract
Methods and systems for classifying incoming and/or outgoing packets to sessions in a media gateway store session identifiers for active sessions in a media gateway in a memory. Each session identifier is a combination of a local network address, a local port number, a remote network address, and a remote port number for the session. Alternatively, each session identifier is a combination of a local network address and a local port number. An incoming and/or outgoing packet is classified to one of the active sessions by using network address and port number information from the packet to perform a lookup for a corresponding session identifier in the memory.
