Abstract: failure scenario. However, since the failure of network components is probabilistic, the single-failure model may not well fit some large networks. On the other hand, different applications or end users need different levels of fault tolerance, and differ in how much they are willing to pay for the service they get. In this thesis, we assume a probabilistic failure environment and choose the connection reliability as a QoS parameter to denote the different levels of fault tolerance. We investigate the use of segmented protection to improve network resource efficiency while performing dynamic routing of reliability-differentiated connection. We also consider incorporating backup sharing in such probabilistic failure environment. In addition, we present a resource-efficient approach to dynamically route connections with differentiated joint-QoS requirements: reliability and recovery time.
