Both protocols are used and are very similar. The IEEE 802.5 token ring technology provides for data transfer rates of either 4 or 16 megabits per second. Inserts a message and destination identifier in the frame. Frame examined by successive workstation. Workstation sees that it is the destination for the message.
Message is removed.
Frame continues to circulate empty. Process can start again . The token scheme can also be used with bus topology LANs. When either the destination device or LAN server reads the message the token is reset back to 0 allowing the continued use by another device. As all the devices are exacted the same opportunity to use the network when traffic increases this process remains extremely efficient.
