Abstract
Apparatus and methods for epoch retransmission in a packet network device are described. In at least one embodiment, epoch receivers check received epoch data for errors. When an error is detected, a receiver is allowed to request that the entire epoch be retransmitted. All epoch senders retain transmitted epoch data until the time for requesting a retransmission of that data is past. If retransmission is requested by any receiver, the epoch is “replayed.” This approach mitigates the problem of dropping multiple packets (bundled in a large epoch) due to an intraswitch error with the epoch. Other embodiments are also described and claimed.
