一种基于软件定义网络的服务功能链优化部署机制.

For the software-defined networking environment, the existing service function chain deployment method failed to fully consider the resource utilization of the entire network, this paper proposed a service chain optimal deployment mechanism based on the efficient heuristic algorithm. Firstly, this mechanism gave the overall structure of the service chaining deployment, and introduced an integer linear programming model. Secondly, this paper proposed an efficient heuristic algorithm, which ran in first sort after greed manner and effectively used network resources and balanced load under the constraints of resource and delay. The obtained simulation results show that compared to other deployment algorithms, the proposed algorithm reduces the load balancing and time complexity while improving the request acceptance rate.
