CPCQ-an alternative to DQDB

The authors present a new protocol, referred to as CPCQ (counteracting priority coupled queue). It may be viewed as a simpler alternative to DQDB (distributed queue dual bus). It can operate quite effectively in the high-speed fiber-optic environment. In addition, it is analytically more tractable and can be enhanced to allow for assignable privileges. CPCQ is simpler to implement because the protocol requires only limited sensing. Nodes need not constantly monitor the channel to track the number of outstanding requests for downstream nodes.<
