  • Patent number: 11329877
    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.

  • Patent number: 10924573
    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 client is directed to a second server, not in the first tier of servers, and the second server serves the resource to the client. The second server may be in a second tier of servers or it may be an origin server.

  • Publication number: 20210044652
    Abstract: A computer-implemented method, in a content delivery (CD) network that delivers content on behalf of multiple content providers. The method includes, at a server in the CDN, wherein the server is currently processing at least one other request in at least one other session: receiving a connection request from a client, the connection request being associated with a corresponding content request; determining whether handling the content request will cause the server to become overloaded; and, based on the determining in (B) and on information about the content request, conditionally (i) accepting the content request, and (ii) terminating or throttling at least one session on the server.

  • Patent number: 9749381
    Abstract: A content delivery (CD) service in a CDN maintains property invalidation information on said CD service including, for each property, a list of one or more group invalidation commands. New group invalidation commands are added by selectively merging one or more invalidation commands to form a merged invalidation command and inserting the merged invalidation command into said list, wherein the merging is based on a length of common prefix of elements in said list. A per property common prefix list is maintained for invalidation commands in each property list.
