This thesis focused on SDH communication network protections.When some failures occur
some routes must be searched to build enough paths for restoration.At the same time
in building a communication network
we will spend the least spare resouce to satisfy the protection demand.The first step to solve this problem is presenting a mathematic model for it.It is also the most difficult and important step.When a mathematic model is built
the problem can be solve by mathematic algorithm.
