On the base of the timed-token Protocol, Which is applied in the Fiber Distribrted Data Interface(FDDI), this paper improves the token ring algorithm, a known mutual exclusion methods for a Process to access to critical region in distributed system, to provide principle base for the distinguishing of loss of token from a long time rotation by confining the rotation in a short time.

Research and Implement of Network Traffic Shaping Based on Leak Bucket Method and Token Bucket Algorithm;

Robustness of the token bucket algorithm is studied under the condition of different token banks and probability p.

According to this algorithm, the shortage of primary bucket algorithm and token bucket algorithm is overcome.

5 protocol is a famous international standard for Token-Ring local area network( LAN).

Train Monitor System based on token ring network topology;

, this paper gives a method about the implementation of token ring access control, sets up a queue model for token ring based on the method,and gives its mathematical analysis and performance analysis.

Implement of token ring bus in radar signal processor;

Unifying the serial bus and the token ring bus\'s characteristic,through the use of high performance chip and the reasonable high-speed design,the token ring network bus based on LVDS transmission technology is proposed in this paper.

Aiming at this situation,a new media access control(MAC) mechanism based on multiple token-rings was proposed.
