countdown counter (CC)

In Distributed Queue Dual Bus (DQDB), each network node has two counters: the Request Counter (RC) and the Countdown Counter (CC). While the Request Counter is an up counter for send requests, the Coubtdown Counter is a down counter. The Countdown Counter is loaded with a value and reduced by one step by each ResetSlot. It determines the time slot reserved by the own station on the transmit bus.
