Preface
A three-layer hierarchy is typically used in modern telecommunication systems in order to achieve high performance and reliability. The three layers, namely core, distribution, and access, perform different roles for service fulfillment. The core layer is also referred to as the network backbone, and it is responsible for the transfer of a large amount of traffic in a reliable and timely manner. The network devices (such as routers) in the core layer are vulnerable to hard-to-detect/hard-to-recover errors. For example, the cards that constitute core router systems and the components that constitute a card can encounter hardware failures. Moreover, connectors between cards and interconnects between different components inside a card are also subject to hard faults. Also, since the performance requirement
