The token bus network is a standard in which tokens are passed along a virtual ring. In the token bus network bus topology is used as physical media.
In this, the virtual ring is created with stations and therefore tokens are subsequently passed from a station during a sequence with this virtual ring. Every station or node in toke bus network knows the address of its predecessor station and its successor station. A node (station) can transmit the data if and only if it has a token. It’s working rule is analogous to the token ring network.
It is defined by the IEEE 802.5 standard. In the token ring network the token is passed over a physical ring instead of virtual ring.
In this a token is a special frame and a station can transmit the data frame if and only if it has a token. And The tokens are issued on successful receipt of the data frame.
Let’s see the difference between the token bus and the token ring:-
|S.NO||TOKEN BUS Network||TOKEN RING Network|
|1.||In the token bus network the token is passed along a virtual ring.||While in the token ring network the token is passed over a physical ring.|
|2.||The token bus network is simply designed for the large factories.||While the token ring network is designed for the offices.|
|3.||The token bus network is defined by the IEEE 802.4 standard.||While the token ring network is defined by the IEEE 802.5 standard.|
|4.||Token bus network provides better bandwidth.||While the token ring network does not provide better bandwidth as compared to token bus.|
|5.||In token bus network, Bus topology is used.||While in token ring network, Star topology is used.|
|6.||The maximum time it takes to reach the last station in a token bus network cannot be calculated.||While the maximum time to reach the last station in the token ring network can be calculated.|
