Request routing using a popularity identifier at a DNS nameserver

A system comprising:

• a computing device, having a processor and a memory to present a first network point of presence associated with a content delivery network service provider,
• wherein the first network point of presence includes a first DNS nameserver component that receives a DNS query from a client computing device,
• wherein the DNS query corresponds to a resource associated with a first resource identifier,
• wherein a popularity identifier is included in a DNS portion of the first resource identifier accessible to the first DNS nameserver component,
• wherein the popularity identifier is associated with the resource, and
• wherein the first network point of presence is operative to:
• process the DNS query at the first DNS nameserver to obtain the popularity identifier;
• obtain an alternative resource identifier in response to the DNS query, wherein the alternative resource identifier is selected, at least in part, as a function of the popularity identifier;
• and
• transmit the alternative resource identifier to the client computing device.

A system comprising:

• a computing device, having a processor and a memory to present a first network point of presence associated with a content delivery network service provider,
• wherein the first network point of presence includes a first DNS nameserver component that receives a DNS query from a client computing device,
• wherein the DNS query corresponds to a resource associated with a first resource identifier,
• wherein a popularity identifier is included in a DNS portion of the first resource identifier accessible to the first DNS nameserver component, and
• wherein the first network point of presence is operative to:
• parse, by the first DNS nameserver component, at least a portion of the first resource identifier so as to obtain the popularity identifier for use in further obtaining popularity information regarding the resource, wherein the popularity information corresponds to the popularity identifier;
• generate a second resource identifier based at least upon at least a portion of the popularity information, wherein the second resource identifier resolves to a domain corresponding to the content delivery network service provider;
• and
• transmit the second resource identifier to the client computing device.

A non-transitory computer-readable storage medium storing computer-executable instructions that when executed by a processor perform operations comprising:

• receiving a DNS query from a client computing device by a computing device associated with a content delivery network service provider, wherein the DNS query corresponds to a resource associated with a first resource identifier, wherein a popularity identifier is included in a DNS portion of the first resource identifier accessible to a DNS nameserver component;
• parsing, by the DNS nameserver component, at least a portion of the first resource identifier so as to obtain the popularity identifier for use in further obtaining popularity information regarding the resource, wherein the popularity information corresponds to the popularity identifier;
• generating a second resource identifier based at least upon at least a portion of the popularity information, wherein the second resource identifier corresponds to a resource cache component of the content delivery network service provider;
• and
• transmitting the second resource identifier to the client computing device.
