Abstract
By using an extended bitmap window and arrival sequence numbers, a multiprocessor system may perform anti-replay checks on incoming packets in a similar order as a single processor system. In one implementation, a device may provide an anti-replay check window that includes an original window and an extension window, the original window being contiguous to the extension window. In addition, the device may receive a packet with an anti-replay sequence number and receive another packet whose anti-replay sequence number is within a range of the original window. In addition, the device may determine if the packet has arrived before the other packet by less than a threshold if the anti-replay sequence number of the packet falls within a range of the extension window. Further, the device may retain the packet if the packet has arrived before the other packet by less than the threshold.
