Abstract: Using the ALTO Service, networking applications can request through the ALTO protocol information about the underlying network topology from the ISP or Content Provider. The ALTO Service provides information such as preferences of network resources with the goal of modifying network resource consumption patterns while maintaining or improving application performance. This document describes, in one example, an ALTO server that intersects network and cost maps for a first network with network and cost maps for a second network to generate a master cost map that includes one or more master cost entries that each represent a cost to traverse a network from an endpoint in the first network to an endpoint in the second network. Using the master cost map, a redirector may select a preferred node in the first network with which to service a content request received from a host in the second network.

Abstract translation: 使用ALTO服务，网络应用程序可以通过ALTO协议向ISP或内容提供商请求关于底层网络拓扑的信息。 ALTO服务提供诸如网络资源的偏好的信息，目的是在维护或提高应用程序性能的同时修改网络资源消耗模式。 在一个示例中，该文档描述了与第一网络的网络和成本图相交的ALTO服务器，其具有用于第二网络的网络和成本图，以生成主成本图，其包括一个或多个主成本条目，每个代表成本表示成本 将网络从第一网络中的端点穿过到第二网络中的端点。 使用主成本图，重定向器可以选择第一网络中的优选节点，用于服务于从第二网络中的主机接收的内容请求。
