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.

DQDB: Distributed Queue Dual Bus (Defined in IEEE ) – Network Protocols Handbook [Book]
This page was last edited on 16 Mayat KamalJohnny W. HullettRobert M. WongHossam S. 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. The algorithm was remarkable protocll its extreme simplicity.

The headers on the reverse bus communicated requests to be inserted in the protofol queue so that upstream nodes would know that they should allow DQDB cells to pass unused on the forward bus. Fairness in DQDB revisited: Topics Discussed in This Paper. The DQDB may be thought of as two token rings, one carrying data in each direction around the ring. Metropolitan area networks Local area networks Link protocols.

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.
