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.NOToken Bus NetworkToken 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.
7In a token bus network, coaxial cable is usedIn token ring network, twisted pair and fiber optic is used.
8In 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.
