Research of mutual exclusion algorithm in distribution systems

It′s very important to use a fair and easy implementation distributed mutual exclusion algorithm to ensure the data,1ogic and time consistency of a distributed system,and mutual exclusion is a very important issue in the distribution systems.The mutual exclusion problem(mutex) means how to solve the clash problem that one processes request to enter a critical section at the same time.Mutual exclusion between courses in distributed system are expatiated detailedly in this paper.Some kinds of algorithms are discussed and their characters are also analyzed,and finally this article gives K-mutual exclusion algorithm,and at the same time introduces satisfied condition and how to implement k-mutual exclusion algorithm.
