OverSim:可扩展的应用层组播网络仿真框架
OverSim: A Scalable Application-Layer Multicast Network Simulation Framework
摘要
Abstract
As a viable alternative of IP multicast, application-layer multicast is increasingly becoming a hot research topic of Internet applications. How to simulate large-scale, dynamic application-layer multicast overlay network has become a common problem faced by the application layer multicast scheme researchers. Based on the analysis of several mainstream network simulators, this paper proposes the OMNet++ based overlay network simulation framework OverSim in order to simulate the large-scale and dynamic application layer multicast overlay network, and further analyzes the solution of scalable application layer multicast. At last, we simulate the application-layer multicast protocol Scribe on the OverSim and analyze the simulation results. The simulation results show that the OverSim can steadily simulate overlay network with thousands of nodes under the limited hardware environment. Besides, the simulation consumes low system memory that is linearly related with the overlay network scale.关键词
