Point of presence management in request routing

Abstract

A system and method for the management of client computing device DNS queries and subsequent resource requests within a content delivery network service provider domain are provided. The management of the DNS queries can include the selection of computing devices corresponding to various Point of Presence locations for processing DNS queries. Additionally, the management of the content requests can include the selection of computing devices corresponding to resource cache components corresponding to various Point of Presence locations for providing requested content. The selection of the computing devices can incorporate logic related to geographic criteria, testing criteria, and the like.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 892,819, entitled “POINT OF PRESENCE MANAGEMENT IN REQUEST ROUTING” and filed on Sep. 28, 2010, the disclosure of which is herein incorporated by reference.BACKGROUND[0002]Generally described, computing devices and communication networks can be utilized to exchange information. In a common application, a computing device can request content from another computing device via a communication network. For example, a user at a personal computing device can utilize a software browser application to request a Web page from a server computing device via the Internet. In such embodiments, the user computing device can be referred to as a client computing device and the server computing device can be referred to as a content provider.[0003]Content providers are generally motivated to provide requested content to client computing devices, often with consideration of efficient...

AI Technical Summary

Benefits of technology

The patent text describes a system for managing the delivery of requested content to client computing devices through a content delivery network service provider. The system takes into consideration factors such as efficient transmission of requested content and cost associated with the transmission of content to provide the best service to client computing devices. The technical effects of the patent text include improved efficiency in managing content requests and reducing latency in delivering requested content.

Problems solved by technology

For larger scale implementations, a content provider may receive content requests from a high volume of client computing devices, which can place a strain on the content provider's computing resources.

Additionally, the content requested by the client computing devices may have a number of components, which can further place additional strain on the content provider's computing resources.
