What is Token Ring?
Token ring is a local area network technology that can host protocols in the data link portion of the OSI model. A special structure called "token," consisting of 3 bytes, circulates throughout the entire ring.
When no stations are sending data, the special token structure circulates in the network. When a station wants to send data, it converts the token structure into its data structure. Once the sent data structure returns to the station, it converts the structure back into a token. If there is a transmission error, a special station called an active monitor identifies the problem when there are issues such as the token structure not being in the network or multiple tokens circulating. Tokens are either deleted or re-added if they are crucial.
In a 4 Mbps token ring network, only one token can circulate, while in a 16 Mbps network, multiple tokens can circulate.
