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.

Abstract: A content delivery method including the operations of receiving a uniform resource locator resolution request at an authoritative name server for a domain where the uniform resource resolution request is received based, at least in part, on a host name of the uniform resource resolution request where the host name is uniquely related to a resource associated with the uniform resource resolution request. The method further including the operation of tracking a popularity of the resource based on the host name uniquely related to the resource and providing a location within a network capable of delivering the resource where the provided location is based on the popularity of the resource.

Abstract: A content delivery network (CDN) includes multiple cluster sites, including sites with streaming media servers, caching servers and storage devices accessible to the caching servers for storing streaming content. Interface software is configured to initiate retrieval, by a caching server, of electronic streaming resources from the one or more storage devices in response to requests for the electronic streaming resource received by the streaming media server.

Abstract: Provided are methods and systems for dynamic binding in the context of content delivery. For example, the methods and systems may be implemented as a dynamic binding process that maps a content provider to a first set of content servers in a content distribution network. The dynamic binding process may then facilitate the content to be received from the content provider so that the content can be distributed by the first set of content servers in the content distribution network. The dynamic binding process further monitors network traffic associated with the content from the content provider and determines at least one metric associated with the network traffic. Additionally, the dynamic binding process can remap the content provider to a second set of content servers in the content distribution network based on at least one of the metrics.

Abstract: Examples described herein relate to apparatuses and methods for associating a first account with a second account, the first account being hosted by a first server, the second account being hosted by a second server, including but not limited to, authenticating, by the first server, first login credentials associated with the first account, wherein the first login credentials are received from a user device, receiving, by the first server from the user device, second login credentials associated with the second account, sending, by the first server, the second login credentials to the second server for authentication, in response to determining that the second login credentials are authenticated by the second server, associating, by the first server, the first account with the second account, and connecting, by the first server to the second server, to allow the user device to access services commensurate with the second account without prompting the user device for the second login credentials.

Abstract: A content delivery (CD) network delivers content on behalf of multiple content providers. A method includes determining that certain content is trending in a first geographic region during a first time period; and, based on the determining, causing the certain content to be prefetched by the CDN in a second geographic region by a given time after said first time period, wherein, during the first time period, the time in the second geographic region is earlier than the time in the first geographic region.

Abstract: Embodiments provide system and methods for a DDoS service using a mix of mitigation systems (also called scrubbing centers) and non-mitigation systems. The non-mitigation systems are less expensive and thus can be placed at or near a customer's network resource (e.g., a computer, cluster of computers, or entire network). Under normal conditions, traffic for a customer's resource can go through a mitigation system or a non-mitigation system. When an attack is detected, traffic that would have otherwise gone through a non-mitigation system is re-routed to a mitigation system. Thus, the non-mitigation systems can be used to reduce latency and provide more efficient access to the customer's network resource during normal conditions. Since the non-mitigation servers are not equipped to respond to an attack, the non-mitigation systems are not used during an attack, thereby still providing protection to the customer network resource using the mitigation systems.

Abstract: A content delivery method, and related apparatus, that involves the operations of receiving a request for a content resource including at least one embedded resource with a tag. Upon identification of the tag, using at least one delivery parameter to generate a modified embedded resource. Embedding the modified embedded resource in a content resource, such as as an HTML document. Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.

Abstract: A computer-implemented method is operable in a network comprising multiple delivery service endpoints running on a plurality of devices where each of the delivery service endpoints is constructed and adapted to deliver resources. A plurality of the delivery service endpoints comprise a group, wherein each node in the group has at least one kind of responsibility relating to delivery of resources. The method includes receiving a request at a node; and, based on what kind of responsibility the node has for the request, attempting to process the request outside the group.
