CISE Research Instrumentation: Emulate the Performance of Wide Area Networks

EIA-9911074Matt W.密歇根州立大学CISE研究仪器：模拟广域网的性能密歇根州立大学计算机科学与工程系将购买计算和网络设备。 该设备包括两个24端口机架式交换机、一个8端口路由器、用于网络仿真的PC、四个Web服务器、一个RAID服务器、六个带有无线网络组件的移动的计算设备、一个无线接入点以及机架、显示器和其他支持机架式系统的设备。 该设备将用于实现EMPOWER（模拟广域网性能）环境，该环境将致力于支持计算机科学和工程研究。 EMPOWER允许模拟任意网络拓扑，包括互连的主机和路由器，其中包含WAN端口和LAN端口。 除了仿真网络带宽、丢弃率和模式、延迟分布和后台流量之外，EMPOWER还提供了一个极好的环境来实现和评估不同的QoS方案（如区分服务）和标签交换方案（如MPLS）。 目前的研究包括仿真内核的设计，路由表的配置，网络统计数据的可视化，和GUI配置网络容易。

EIA-9911074Matt W. MutkaMichigan State UniversityCISE Research Instrumentation: Emulate the Performance of Wide Area NetworksThe Department of Computer Science and Engineering at Michigan State University will purchase computing and network equipment. This equipment includes two 24-port rackmount switches, an 8-port router, PCs for network emulation, four web servers, one RAID server, six mobile computing devices with wireless networking components, a wireless access point, and racks, monitors, and other devices to support the rackmounted system. This equipment will be used to implement the EMPOWER (EMulate the PerfOmance of WidE aRea networks) environment that will be dedicated to support research in computer science and engineering. EMPOWER enables the emulation of arbitrary network topologies, including interconnected host machines and routers contains both WAN ports and LAN ports. Beyond emulation of network bandwidth, drop rates and patterns, delay distributions, and background traffic, EMPOWER provides an excellent environment to implement and evaluate different QoS schemes (such as differentiated services) and label swapping schemes (such as MPLS). Current research includes emulation kernel design, routing table configuration, network statistics visualization, and GUI to configure the network easily.
