It addressesdifferent use cases of ALTO such as peer-to-peer file sharing andContent Delivery Networks (CDNs) and presents corresponding examples.The document also includes recommendations for network administratorsand application designers planning to deploy ALTO, such asrecommendations on how to generate ALTO map information.
