Network routers for parallel enterprise servers need faulttolerance as well as high performance to support a seamless value chain of e-business. This paper introduces a new cut-through flow control method, called the pathfinder, which provides an efficient restarting capability without the extra header delivery overhead for normal non-faulty routes.
