EAGER: Collaborative: Aster*x: Load-Balancing Web Traffic Over Wide-Area Networks

该项目提出了一个全面的负载平衡解决方案，以最大限度地减少客户端响应时间，并降低广域网中托管服务的系统成本。该系统名为Aster*x，使用服务器负载和网络拥塞的全局状态，并通过适当的（服务器和路径）对动态路由请求，使用项目人员开发的负载平衡算法计算。GENI网络基础设施将用于Aster*x的广泛部署、评估和演示。Aster*x利用OpenFlow？的逻辑集中控制器，获取全局网络状态和各种粒度的路由流。它将使用PlanetLab和基于ProtoGENI的计算基底来托管复制的Web服务，并从多个位置生成客户端请求。该项目将为四所大学的学生提供一个合作的机会，并在GENI上建立一个相对较大的实验系统。

This project proposes a comprehensive load-balancing solution to minimize client response time and reduce system costs for services hosted in wide-area networks. The system, called Aster*x, uses the global state of server load and network congestion, and dynamically routes the requests over appropriate (server and path) pairs, calculated using the load-balancing algorithms developed by project staff. The GENI network infrastructure will be used for extensive deployment, evaluation, and demonstration of Aster*x. Aster*x exploits OpenFlow?s logically centralized controller to obtain the global network state and route flows of various granularities. It will use the PlanetLab and ProtoGENI-based computation substrate to host the replicated web service and to generate client requests from multiple locations. The project will provide an opportunity for students across four universities to collaborate and build a relatively large experimental system on GENI.
