http://www.webopedia.com/TERM/T/token_bus_network.html

A type of local-area network (LAN) that has a bus topology and uses a token -passing mechanism to regulate traffic on the bus. A token bus network is very similar to a token ring network, the main difference being that the endpoints of the bus do not meet to form a physical ring. Token bus networks are defined by the IEEE 802.4 standard.

doesn't sound like much difference
