| Summary: | The rapid growth of the Internet has made the issue of ensuring reliability and redundancy a big challenge. Studies of these issues using Traffic Engineering and simulation have been extensively done. There has been substantial interest from researchers in the development and contribution of modules in NS-2. Most studies have not taken into account real traffic parameters in their simulation models. Also, there is no comprehensive model consisting of Border Gateway Protocol (BGP) and Hot Potato (HP) routing in the NS-2 network simulator based on real networks. In this paper, Integrated Model is introduced consisting of HP algorithm and BGP integrated into the NS-2 network simulator. The integrated model is then used to simulate the infrastructure of a real production network using actual captured traffic data parameters. The network is modeled with a baseline topology where 5 main nodes were connected together, with redundant links for some nodes. The simulations were repeated for link failures. HP helps in improving the node which experiences a link failure to select shorter distance route to egress router. In the case of a link failure, HP switching time between the links is 0.05 seconds. The integrated model performance was evaluated by comparing trace file before and after link failure or by adding nodes (up to 32). The parameters used for comparison are the packets loss, delay and throughput. The integrated model error percentage obtained for packets loss is 0.025%, delay 0.013% and throughput 0.003%. |
