WDM ring network is gaining acceptance as its flexibility, simple management and well survivability. This paper looks at several kinds of WDM ring protection networks and some problems, which we must pay attention to, and then analysis and compares their performance. Finally, we give some principles of design the WDM ring protection networks.
