Genesis:a system for large-scale parallel network simulation

摘要: We describe a novel approach to scalability and efficiency of parallel network simulation that partitions the networks into domains time intervals. Each domain is simulated independently concurrently with others over same interval. At end each interval, packet delays drop rates for inter-domain flow are exchanged between simulators. The simulators iterate interval until information converges constant value within prescribed precision. After convergence, all progress next This allows parallelization infrequent synchronization.The biggest challenge this method ensure iteration convergence protocols, such as TCP, adjust source rate current conditions. main contribution paper demonstrate by judicious design processing exchange, proposed efficiently parallelizes TCP flows.
