Abstract

The concept of using an overlay protocol packet embedded as the payload in a network control protocol to measure and calculate the overall, end-to-end latency of network control protocol messages between two nodes in a network is introduced. Example embodiments can be used as a generic solution to efficiently determine the overall, end-to-end latency of almost any network control protocol. By embedding an overlay protocol packet inside a network control protocol, the embedded overlay protocol packet travels the same path and experiences the same network conditions (latency, etc.) as any other network control protocol message. Thus, the measured/calculated latency accounts for any “host” layer latencies not normally captured by tools that merely measure the “IP” latency (i.e. the latency of network control protocol packets from the “IP” layer of one network node to the “IP” layer of another network node).
