Abstract

Dynamic reconfiguration of high speed switched network is the process of changing from one routing function to another while the network remains in running mode. Current distributed switch-based interconnected systems require high performance, reliability and availability. These systems changes their topologies due to hot expansion of components, link or node activation and deactivation. Therefore, in order to support hard real-time and distributed multimedia applications over a high speed network we need to avoid discarding packets when the topology changes. Thus, a dynamic reconfiguration algorithm updates the routing tables of these interconnected switches according to new changed topology without stopping the traffic. Here, we propose an improved deadlock-free partial progressive reconfiguration (PPR) technique based on UP/DOWN routing algorithm that assigns the directions to various links of high-speed switched networks based on pre-order traversal of computed spanning tree. This improved technique gives better performance as compared to traditional PPR by minimizing the path length of packets to be transmitted. Moreover, the proposed reconfiguration strategy makes the optimize use of all operational links and reduces the traffic congestion in the network. The simulated results are compared with traditional PPR.
