Fault models are constituted by analyzing various network faults.A new distributed fault tolerance scheduling algorithm based on credit scheme was proposed to convert the various network faults into the impacts on different input stage queues.Using credit scheme not only induces traffic to steer clear of the fault-impact areas,but also distributes the load balance among availability centre stage switches.Theoretical analysis shows that the algorithm can tolerate at least m-n(m,n is the port number of input and output of input stage switch module) network faults.Simulation analysis shows that the algorithm can keep the system throughout above 95% under various network faults.
