DQDB PROTOCOL PDF

Distributed Queue Data Interface (DQDB) and put up as IEEE standard. The basic The protocol does not have greedy stations. In all others, if a. The Distributed Queue Dual Bus (DQDB) protocol is being considered by the IEEE and ANSI T1S as an important component in their Metropolitan Area. Abstract: The draft distributed queue dual bus (DQDB) protocol is a proposed standard for metropolitan area networks (MANs). A study is made of fairness issues.

Point of View computer hardware company Simulation. Each node in a DQDB network maintains a pair of state variables which represent its position in the distributed queue and the size of the queue. In the DQDB algorithm, a distributed queue was implemented by communicating queue state information via the header.
