Abstract
For each node, elapsed periodic time intervals are provided and counted since the transmission of a link integrity indication frame, a frame which can be received by all other nodes on the network and which contains a source identifier. Frames are received from a sending node and a node state status and a current received frame source address are maintained during each periodic time interval. Upon expiration of the periodic time interval, if the node state status is not indicative of network traffic and a count of the elapsed periodic time intervals since transmission of a link integrity indication frame is greater than a predefined count limit, a link integrity indication frame is transmitted.
