Abstract:
1. A method of aging a data session in a network device, comprising: receiving, by an interface of the network device, a first data unit associated with the data session; storing, by a processor of the network device, a session identifier associated with the data session in a first list of a memory device in the network device; initiating, by the processor, a first timer upon storing the session identifier in the first list, where initiating the first timer includes: storing, by the processor, the session identifier in a second list, of the memory device, subsequent to expiration of the first timer; initiating, by the processor, a second timer upon storing the session identifier in the second list; and aging, by the processor, the data session based on whether another data unit associated with the data session is received prior to expiration of the second timer.
