Abstract

A system and method for accelerating web page delivery is disclosed in one embodiment. Web content requests are made to an edge server of a first point of presence (POP) of a content delivery network (CDN). The web content has embedded resource links. The first POP can rewrite the embedded resource links to route requests for the embedded resource links to any POP in the CDN or even the origin server. In some embodiments, the first POP can decide if the first POP and/or another POP referenced in a rewritten embedded resource link should cache and/or accelerate the resource referenced in the embedded resource link.

Claims

1. A content delivery network (CDN) having a plurality of points of presence (POPs) to deliver content for a plurality of customer accounts, comprising:

one or more processors for executing instructions to;

receive a query from one of the customer accounts to gather analytics information related to delivery of content for the one of the customer accounts;

process the query into an analytics query to gather the analytics information;

gather a first part of the analytics information from a first POP of the plurality of POPs;

process the first part of the analytics information into one or more data cubes;

pass the one or more data cubes along a data bus;

gather a second part of the analytics information from a second POP of the plurality of POPs;

add the second part of the analytics information to the one or more data cubes;

determine that the one or more data cubes reach a predetermined threshold;

originate a message to shut down gathering of the second part of the analytics information; and

send the message to two or more of the plurality of POPs; and

one or more storage media for retaining the instructions.

2. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the first part of the analytics information gathered from the first POP is gathered by an edge server within the first POP.

3. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the one or more processors that execute the instructions that determine that the one or more data cubes reach a predetermined threshold, are within the first POP.

4. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the message to shut down gathering of the second part of the analytics information is sent through at least one server.

5. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the message to shut down gathering of the second part of the analytics information is sent according to a hierarchy of servers.

6. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the predetermined threshold is a measure of an amount of memory consumed by the one or more of the data cubes.

7. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein there are a plurality of predetermined thresholds that have differences among the plurality of customer accounts.

8. The CDN having a plurality of POPs to deliver content for a plurality of customer accounts as recited in claim 1, wherein the analytics information relates to addresses where the content was delivered for the one of the customer accounts.

9. A method for managing aggregation of one or more data cubes within a content delivery network (CDN) having a plurality of points of presence (POPs) that deliver content for a plurality of customer accounts, comprising utilizing a processor of the CDN for:

receiving a query from one of the customer accounts to gather analytic information related to delivery of content;

processing the query into a first analytics query, wherein the first analytics query identifies analytics information;

gathering a first part of the analytics information from a first POP of the plurality of POPs;

processing the first part of the analytics information into one or more data cubes;

passing the one or more data cubes along a data bus;

gathering a second part of the analytics information from a second POP of the plurality of POPs;

adding the second part of the analytics information to the one or more data cubes;

determining that the one or more data cubes reach a predetermined threshold;

originating a message to shut down gathering of the second part of the analytics information; and

sending the message to two or more of the plurality of POPs.

10. The method for managing aggregation of one or more data cubes within CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 9, further comprising utilizing the processor for relaying the notification from the first POP to the remainder of the plurality of POPs.

11. The method for managing aggregation of one or more data cubes within a CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 9, wherein the predetermined threshold is a measure of memory consumption on an edge server of one of the plurality of POPs.

12. The method for managing aggregation of one or more data cubes within a CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 9, wherein the predetermined threshold is a measure of processing resources consumed on an edge server of one of the plurality of POPs.

13. The method for managing aggregation of one or more data cubes within a CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 9, wherein a plurality of predetermined thresholds are related to respective ones of the plurality of customer accounts, and at least two of the plurality of predetermined thresholds are different from one another.

14. The method for managing aggregation of one or more data cubes within a CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 9, wherein at least one of the first and second analytics information relates to content delivery for the one of the customer accounts.

15. The method for managing aggregation of one or more data cubes within a CDN having a plurality of POPs that deliver content for a plurality of customer accounts as recited in claim 14, wherein the at least one of the first and second analytics information relates to addresses for content delivered for the one of the customer accounts.
