摘要

With the enormous increase in the usage of communication networks, protection against node and link failures became essential in the deployment of reliable networks. To manage loss of data due to node failures, we design a network protection strategy that aims to withstand such failures. In this paper we propose a protection strategy against any single node failure in the network. We deploy network coding and reduced capacity in this strategy without adding extra working paths to the readily available connection paths. The strategy is based on representing node failures by the failure of multiple links, and hence is transformed into a protection against multiple link failures. Consequently, the protection strategies proposed in [2], [8] can also be applied for protection against node failures. In addition, we demonstrate the implementation aspects of the premeditated protection strategies.
