Long-distance IP networks are becoming the universal infrastructure to carry all the communication services. These services have different assurance requirements, in terms of availability and serveability and it becomes important an IP network able to offer at the same time both carrier-class and lower quality availability levels. This paper investigates possible strategies that allow reaching these goals, specifically analyzing the cost/benefit ratio of each strategy. In doing that we pay attention to solutions that can be applied to present state-of-the art IP over Optics networks.
