Request routing utilizing cost information
First Claim
1. A computer-implemented method for request routing comprising:
- obtaining a DNS query from a client computing device at a first DNS nameserver, wherein the DNS query comprises a first uniform resource locator (URL), wherein the first DNS nameserver corresponds to a content delivery network (CDN) service provider, and wherein a domain portion of the first URL includes an identifier of the CDN service provider and an identifier of financial cost information attributable to an original content provider for providing services on behalf of the original content provider;
determining that the first URL is associated with an alternative URL as a function of the financial cost information included in the first URL;
transmitting the alternative URL to the client computing device, wherein the alternative URL includes information for causing a DNS query to resolve to a domain corresponding to the CDN service provider and wherein the alternative URL further includes supplemental request routing information not included in the first URL;
obtaining a subsequent DNS query from the client computing device at a second DNS nameserver, wherein the subsequent DNS query corresponds to the alternative URL provided by the CDN service provider and wherein the second DNS nameserver corresponds to the CDN service provider; and
resolving the subsequent DNS query, at the second DNS nameserver.

Abstract
A system, method and computer-readable medium for request routing based on cost information are provided. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of cost information. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat with the content delivery network service provider'"'"'s network until a DNS nameserver resolves a DNS query from the client computing device.

13. A system for request routing comprising:
-
one or more hardware processors to implement a first network point of presence associated with a content delivery network (CDN) service provider, wherein the first network point of presence includes a DNS nameserver that receives a DNS query from a client computing device, wherein the DNS query comprises a first uniform resource locator (URL), wherein a domain portion of the first URL includes an identifier of the CDN service provider and an identifier of financial cost information attributable to an original content provider for providing services on behalf of the original content provider, and wherein the DNS nameserver in the first network point of presence is operative to; determine that the first URL is associated with an alternative URL as a function of the financial cost information included in the first URL; and transmit the alternative URL to the client computing device, wherein the alternative URL includes information for causing a DNS query to resolve to a domain corresponding to the CDN service provider and wherein the alternative URL further includes supplemental request routing information not included in the first URL; one or more hardware processors to implement a second network point of presence associated with the CDN service provider, wherein the second network point of presence includes a DNS nameserver that receives a subsequent DNS query from a client computing device, wherein the subsequent DNS query corresponds to the alternative URL provided by the CDN service provider, and wherein the DNS nameserver in the second network point of presence is operative to; resolve the subsequent DNS query. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
