SONET (Synchronous Optical NETwork) has provided the opportunity to implement standardized next generation optical communications networks. One of the most important aspects of these evolving networks is the ability to survive a catastrophic event. These catastrophic events include loss of communication between sites or the loss of an entire site. This paper will contrast various network survivability solutions with the emphasis on ring networks including operation advantages and disadvantages. An overview of several ring implementations will be discussed including two and four fiber rings concluding with a summary of the various survivability solutions.
