System, device, and method for sending keep-alive messages in a communication network

摘要

A system, device, and method for sending keep-alive messages in a communication network involves determining a reliability factor for communicating with a neighbor and setting the frequency for sending keep-alive messages to the neighbor based upon the reliability factor. The reliability factor is determined based upon the reliability of the neighbor as well as the reliability of the communication link to the neighbor. The frequency for sending keep-alive messages to the neighbor is relatively high if the reliability factor is low. The frequency for sending keep-alive messages to the neighbor is relatively low if the reliability factor is high. The frequency for sending keep-alive messages to the neighbor is dynamically adjusted based upon an updated reliability factor.
