Assessing service survivability under failure conditions in reliable multipath network testbed

Abstract

This study reports that the expected capacity guaranteed routing (ECGR) testbed was built and the face recognition service was provided in the testbed. ECGR, which guarantees that the expected capacity calculated based on link failure probability exceeds the requested capacity of flows, has been proposed. On the ECGR testbed, we verify that the assigned expected capacity meets the required capacity. Fault tolerance experiments were conducted to evaluate the impact of not only single link failure but also multiple link failures on the service. From these evaluations, we verified that it is possible to provide highly reliable services on the ECGR.
