Abstract: Examples described herein relate to systems and methods for tiered updating of configuration data. Updated configuration data is transmitted to different tiers of nodes. The nodes of a first tier are commanded to use the updated configuration data. After waiting to see if any nodes of the first tier communicate a fault after using the updated configuration data, for each of the additional tiers in the CDN it is sequentially repeated to: transmit a command to the nodes of that additional tier to use the updated configuration data; and after waiting to see if any nodes of any tier communicate a fault after using the updated configuration data, transmitting a command to the nodes of another additional tier to use the updated configuration data.

Abstract: Systems and methods for managing configuration changes to a network are provided. In examples, the configuration rules are received and stored in a staging directory. If the configuration rules are validated, the rules are moved to a running directory. Thereafter a request to make a change to a configuration parameter is received. The request may comprise a configuration change object, and the configuration change object may be stored in the staging directory. The configuration change object may be evaluated against the rule (and other rules of the network), and it may be moved to the running directory only after satisfying all applicable rules. In some examples, applying the rule(s) may include determining whether the configuration change exceeds a network limit on changes of a particular type with a preset time period.

Abstract: Examples described herein relate to standardizing content requests and responses in a content delivery network (CDN). An edge node receives a control object including sets of instructions each implementing portions of a customer's business logic. The edge node may receive, from a client, a content request identifying a content item, and may apply a set of the instructions which causes the edge node to (i) determine whether any changes are needed for the benefit of a cache server and whether any changes are need for the benefit of an origin server, and (ii) generate a processed client request identifying the content item and including, if needed, any changes for the benefit of the cache server and the origin server. The edge node transmits the processed client request to the cache server, receives a response from the cache server, and transmits a processed client response to the client.

Abstract: A content delivery network has at least a first tier of servers. A content delivery method includes, at a first server in the first tier of servers, obtaining a request from a client for a resource. If the resource is available at the first server or at a peer of the first server, then the resource is served to the client from the first server. Otherwise, it is determined whether the resource is popular, and if the resource is determined to be popular, then the first server obtains the resource and the first server serves the resource to the client. If the resource is determined not to be popular, the server contacts a second server to obtain the resource, not in the first tier of servers, and the second server provides the resource to the first server. The first server is instructed not to cache the unpopular content.
