Abstract
Signature-based latency extraction systems and related methods are disclosed for network packet communications. Disclosed embodiments generate packet signatures (e.g., hash values) for packets received with respect to points within a network packet communication system. For each received packet, its packet signature is compared to packet signatures stored for previously received packets. If no match is found, the packet signature and a timestamp associated with the newly received packet are stored within one or more packet data tables. If a match is found, then the difference between the timestamp associated with the newly received packet and a timestamp stored with the matching packet signature are used to determine a latency value. The latency values can then be used to determine a variety of latency-related parameters for the network infrastructure being measured, and classification information can also be used to generate latency-related histograms. A variety of embodiments can be implemented.
