Abstract

Techniques for determination of packet retransmission using a time threshold are described. In at least some embodiments, information for a packet that is received is compared to information for previously received packets. If the information for the packet matches a previously received packet, a receive time for the packet is compared to a timestamp for the previously received packet to determine if the packet is a retransmission of the previously received packet. In at least some embodiments, packet information associated with different senders can be stored, e.g., to enable packet information comparison for purpose of retransmission detection. An amount of packet information that is stored can be limited to a certain number of senders to control the impact of packet information storage on memory resources.
