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.

The DQDB may be thought of as two token rings, one carrying data in each direction around the ring.

The headers on the reverse bus communicated 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.

In telecommunicationa distributed-queue dual-bus network DQDB is a distributed multi-access network that a supports integrated communications using a dual bus and distributed queuing, b provides access to local or metropolitan area networksand c supports connectionless data transferconnection -oriented data transfer, and isochronous communications, such as voice communications.
