Abstract
A method for detecting communication failures on a network comprising a server computer connected to multiple client computers, said server and client computers communicating through the transmission of data packets via the network. The method includes the step of periodically sending an echo request message from the server computer to the client computers. Each client computer, following receipt of the echo request message, sends an echo reply message back to the server computer. The method further includes the steps of monitoring the rate at which data packets are received by the server computer; and reducing the frequency at which echo request messages are sent from the server computer to the client computers during periods when the rate at which data packets are received by the server computer exceeds a re-configurable rate value. The frequency at which the echo request messages are sent is dependent upon the rate at which data packets are received by said server computer.
