一种具有负载平衡的虚拟计算环境拓扑

摘要

Through analyzing the characteristics of the topology of the typical P2P systems, a new topology generating method which includes birth, growth and maturity of three stages and supports multi-node concurrent joining in the topology was proposed. The results show that iVCE topology generation method can produce stable structure, with load balancing capacity of the network topology. The degree of their super-node obeys a normal distribution law, the average path length between nodes show topological features with the small world. This method can support simulation of the research and design of practical iVCE system.%通过分析典型P2P系统的拓扑结构特征，提出一种包括产生、成长和成熟运行的三阶段支持多节点同时并行加入的iVCE拓扑生成方法。研究结果表明：该方法可以产生结构稳定、具有负载均衡能力的网络拓扑结构。其超级节点度呈现一种正态分布特征，平均节点间最短路径长度显示拓扑具有小世界特征；该拓扑生成方法可为研究、设计实际的iVCE系统仿真提供支持。
