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 implements enhancements to the ALTO service to enable initiating incremental updates of network and cost maps to ALTO clients upon receiving status information from a content delivery network (CDN) node.

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，本文档描述了实现对ALTO服务的增强的ALTO服务器，以便在从内容传送网络（CDN）节点接收到状态信息时，启动对ALTO客户端的网络和成本映射的增量更新。
