Abstract
A system and method for handling stale messages is presented. A first message is transmitted to a peer entity. The first message includes a first timestamp. A second message is received from the peer entity. The second message is related to the first message and includes a second timestamp. A third message is received from the peer entity. The third message includes a third timestamp. A staleness of the third message is determined using the first timestamp, second timestamp, and third timestamp. When the third message is stale, the third message is at least one of ignored and discarded. When the third message is not stale, the third message may be processed.
