 | | DQDB: Distributed Queue Dual Bus in IEEE 802.6 | | | The data rate fluctuates due to many hosts sharing a dual bus as well as the location of a single host in relation to the frame generator, but there are schemes to compensate for this problem making DQDB function reliably and fairly for all hosts. | | | DQDB: Distributed Queue Dual Bus Defined in IEEE 802.6 |

| | In addition, the authors prove the scheme's correctness, design an algorithm to solve its related problem of virtual circuit identifier type selection and discuss its implementation details. | | | To solve this problem, the authors propose a new pre-arbitrated slot access scheme, distributed slot reuse with silence detection, which can greatly improve utilization by taking advantage of two features in voice communications, silence detection and source/destination locality. | | | To cope with this situation, the authors investigate the issue of how to support wireless voice communications efficiently in personal communication networks with distributed queue dual bus networks as backbones. |

| | Distributed-queue dual-bus - Wikipedia, the free encyclopedia |
| | In telecommunication, a 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 networks, and (c) supports connectionless data transfer, connection-oriented data transfer, and isochronous communications, such as voice communications. | | | IEEE 802.6 is an example of a network providing DQDB access methods. | | | This page was last modified 07:09, 30 April 2005. |
