Workshop on Assurance of Networking Systems Dependability Service Level Agreements

Two main leading communication technologies co-exist in today's interconnected networking systems and are converging: switching and routing. These two technologies have two different and complementary levels of fault detection and recovery. Switching resiliency is focused on sensitivity to delays and connectivity whereas routing resiliency is focused on traffic losses and traffic integrity. This workshop investigates the issues and challenges of assuring that a multi-service converged networking system meet tight reliability requirements to meet service level agreements. In particular, the workshop will be focused on discussing and investigating the following questions: 1. What are the challenging issues of reflecting and estimating the contribution of the various network and protocol levels of resiliency to the service availability and reliability? 2. How to aggregate the complexity and interactions from four levels of networking functions (Physical, link, network and transport layers) and work with a viable model that reflects the networking system behavior from the service provider and the service user standpoints?
