Modeling the traffic demands accurately has important significance for network resource utilization and performance optimization. The uncertainty of demands has made the long term forecasting of traffic a particularly difficult problem. So the traffic model named as sliding scheduled lightpath demands (SSLDs) is considered in this paper. A timedisjointness maximizing algorithm is proposed, which is combined with simulated annealing (SA) algorithm to solve routing and resource assignment problem for SSLDs. This solution is evaluated and compared with two fixed routing algorithms. Simulation results show that SA algorithm has a better performance for routing and resource assignment.

Research P2P streaming media scheduling algorithm. Aim at how to make sure that the smaller number data blocks reach priorly, propose an evaluated priority based P2P streaming media scheduling algorithm(EPBSMSA). The algorithm calculates the data block priority according to its rarity, urgency and transmission time. Simulation proves that the algorithm is effective.
