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.

该项目提出了一种全面的负载平衡解决方案，以最大限度地缩短客户端响应时间并降低广域网中托管服务的系统成本。该系统称为 Aster*x，使用服务器负载和网络拥塞的全局状态，并通过使用项目人员开发的负载平衡算法计算的适当（服务器和路径）对动态路由请求。 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 的逻辑集中控制器来获取全局网络状态和各种粒度的路由流。它将使用基于 PlanetLab 和 ProtoGENI 的计算基底来托管复制的 Web 服务并生成来自多个位置的客户端请求。该项目将为四所大学的学生提供一个机会，在GENI上合作并建立一个相对较大的实验系统。
