IEEE 802.6 DQDB PDF

It can be defined as a high speed shared medium access control protocol that is used over a bus network. It has two unidirectional buses, for controlling purposes, where the bus can carry data, video, and voice over a network with bandwidth being allocated as per time slots. The advantage of using the paired bus is that it is used to tackles failure configuration. It can be extended up to 30 miles at Mbps. The start of the bus being represented as a square and the end of the bus being represented as a triangle Fig. Bus A traffic moves from right to left i.

In this context, MAC addresses are used in the medium access control protocol sublayer. It is a switching service that provides data transmission in the range between 1. To date, he has supervised 75 PhDs to completion and currently mentors 18 advisees, mainly PhD students. References McDysan, David E. Technical experts from all over the world participate in the development of IEEE standards.

Isochronouswhere data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also out of the scope of this standard.

As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or no separator see Notational conventions below.

Jump to navigation Jump to search 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 The DQDB may be thought of as two token rings, one carrying data in each direction around the ring. They both settled on essentially a byte data frame with a 5-byte header.
