Abstract
A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.
Claims (28)
1. A computer-implemented method comprising:
obtaining, at a Domain Name System (DNS) server, a DNS query from a client computing device, wherein the DNS query is associated with a requested resource and corresponds to a uniform resource locator (URL);
determining a class of the client computing device associated with the DNS query, wherein the class is included in the URL;
selecting a cache component for providing the requested resource based on routing information for the class; and
causing transmission of identification information for the cache component to the client computing device in response to the DNS query.
2. The computer-implemented method as recited in claim 1 further comprising monitoring performance associated with delivery of the requested resource using the cache component.
3. The computer-implemented method as recited in claim 2 further comprising modifying the routing information for the class based on the delivery performance of the requested resource using the cache component.
4. The computer-implemented method as recited in claim 3 , wherein modifying the routing information for the class comprises modifying a list of cache components for processing the resource request for the class.
5. The computer-implemented method as recited in claim 4 , wherein modifying the routing information for the class comprises modifying probabilities of selection of particular cache components used for processing the resource request for the class.
6. The computer-implemented method as recited in claim 1 , wherein the routing information includes identification of a plurality of cache components.
7. The computer-implemented method as recited in claim 6 , wherein the routing information includes information associated with a probability of selection of individual cache components.
8. The computer-implemented method as recited in claim 7 , wherein selecting the cache component comprises selecting the cache component having a lower probability of selection.
9. The computer-implemented method as recited in claim 1 , wherein the routing information includes a probability of selection of an individual cache component for delivery of the requested resource.
10. The computer-implemented method as recited in claim 1 , wherein selecting the cache component is further based on load balancing criteria.
11. A system comprising:
a first network point of presence (POP) of a content delivery network (CDN) service, wherein the first network POP includes a first Domain Name System (DNS) server that receives a first DNS query from a client computing device, wherein the first DNS query is associated with a requested resource and corresponds to a uniform resource locator (URL), and wherein the first DNS server in the first network POP is associated with a memory and operative for:
determining a class of the client computing device associated with the first DNS query, wherein information identifying the class is included in the URL;
selecting a cache component for providing the requested resource based on routing information for the class; and
causing transmission of identification information for the cache component to the client computing device in response to the first DNS query.
12. The system as recited in claim 11 further comprising monitoring performance associated with delivery of the requested resource using the cache component.
13. The system as recited in claim 12 further comprising modifying the routing information for the class based on the delivery performance of the requested resource using the cache component.
14. The system as recited in claim 13 , wherein modifying the routing information for the class comprises modifying a list of cache components for processing the resource request for the class.
15. The system as recited in claim 14 , wherein modifying the routing information for the class comprises modifying probabilities of selection of particular cache components used for processing the resource request for the class.
16. The system as recited in claim 11 , wherein the routing information includes identification of a plurality of cache components.
17. The system as recited in claim 16 , wherein the routing information includes information associated with a probability of selection of individual cache components.
18. The system as recited in claim 17 , wherein selecting the cache component comprises selecting the cache component having a lower probability of selection.
19. The system as recited in claim 11 , wherein the routing information includes a probability of selection of an individual cache component for delivery of the requested resource.
20. The system as recited in claim 11 , wherein selecting the cache component is further based on load balancing criteria.
