abstract
A key challenge in computer networking is how to organize network topology effectively among a large number of servers in the cloud storage system. In a cloud environment, the topology, which is different from the underlying topology, may be established in any form at any potential edge peers. The cloud content delivery network (CDN) always faces problems of complex distributed path creation, cache update, load balancing, etc. To address the problem as a static content delivery, we propose an Improved Heuristic Genetic Algorithm for Static Content Delivery in Cloud Storage (IHGA-SCDCS) based on a resource management model and cost model. The static content delivery in cloud storage is abstracted into mathematical model for set solving problem, which is then solved by an improved Genetic Algorithm (GA). Finally, the optimal solution is reduced to an optimal content delivery program. The simulation experiment, based on CloudSim, shows that IHGA-SCDCS can effectively obtain optimal solution while reducing delivery cost.
Conclusion
In this paper, a resource management model and a cost model for cloud storage were proposed. Based on the models, an improved genetic algorithm for static content delivery set covering problem was constructed and a validated simulation experiment was undertaken. The experiment results showed that the IHGA-SCDCS can solve static content delivery problem in cloud storage. In the future, the research will be focused on problems of metadata copy storage and life cycle to ensure the consistency and integrity of all cache copies in the network.
