From Wikipedia, the free encyclopedia.
In a ring network, such as a Token ring network, the ring latency is the time required for a signal to propagate once around the ring.
Ring latency may be measured in seconds or in bits at the data transmission rate.
Ring latency includes signal propagation delays in (a) the ring medium, (b) the drop cables, and (c) the data stations connected to the ring network.
