令牌总线:
令牌总线网络是一种标准,其中令牌沿虚拟环传递。在令牌总线网络中,总线拓扑被用作物理介质。

在这种情况下,虚拟环由站创建,因此令牌随后在具有该虚拟环的序列期间从站传递。令牌总线网络中的每个站或节点都知道其前任站和后继站的地址。一个节点(站)可以传输数据当且仅当它有一个令牌。它的工作规则类似于令牌环网络。

令牌环:
它由 IEEE 802.5 标准定义。在令牌环网络中,令牌通过物理环而不是虚拟环传递。

在这种情况下,令牌是一个特殊的帧,当且仅当它有令牌时,站点才能传输数据帧。并且在成功接收到数据帧时发出令牌。

让我们看看令牌总线和令牌环之间的区别:-

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.
