为实现大规模仿真网络拓扑自动映射到有限物理硬件资源,针对求解网络拓扑子网分割最优解这一难题,提出了一种充分考虑物理节点处理能力强、硬件环境一致性好等的情况,采用模拟退火算法进行子网分隔,以求解近似最优解.此外,提出采用网络拓扑分层预处理的方式简化复杂网络结构模型,以减少模拟退火算法中节点映射规模,提高网络子网分割和拓扑映射的效率.
In order to realize the automatic mapping of large-scale simulation network topology to limited physical hardware resources, aiming at the problem of solving the optimal sub-network segmentation in network topology, this paper presents a situation that fully considers the physical node processing ability and the hardware environment consistency, The simulated annealing algorithm is used to divide the sub-networks to find the approximate optimal solution.In addition, a hierarchical network preprocessing method is proposed to simplify the complex network structure model to reduce the node mapping scale in the simulated annealing algorithm and improve the network sub-network segmentation and Topology mapping efficiency.
