Difference between Token Bus and Token Ring Network
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 the token 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. Its working rule is analogous to the token ring network.
Token Ring is defined by the IEEE 802.5 standard. In the token ring network, the token is passed over a physical ring instead of a 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.
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 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 the token bus.|
|5.||In a 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.|
|7||In a token bus network, coaxial cable is used||In token ring network, twisted pair and fiber optic is used.|
|8||In a token bus network, the cable length is 200m to 500m.||In a token ring network, the cable length is 50m to 1000m.|
|9.||In token bus network, distributed algorithm provide maintenance.||In a token ring network, a designated monitor station performs station maintenance.|
