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.

Fairness in DQDB revisited: This page was last edited on 16 Mayat In the DQDB algorithm, a distributed queue was implemented by communicating queue state information via the header. The headers on the reverse bus pdotocol requests to be inserted in the distributed queue so that upstream nodes would know that they should allow DQDB cells to pass unused on the forward bus.
