Abstract: Various embodiments of the present disclosure relate to a computer-implemented method of receiving an invalidation command that includes a first asset identifier, and a set of extension value fields, identifying a first file that is stored in a first cache device and is associated with an identifier matching the first asset identifier, comparing attributes of the first file to the set of extension value fields, and upon determining that, for each extension value field, at least one attribute of the first file matches at least one value of the extension value field, causing the first file in the first cache device to be preserved, or upon determining that, for at least one extension value, at least one attribute of the first file does not match at least one value of the extension value field, causing the first file to be invalidated.

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: Aspects of the present disclosure involve provisioning customers of an aggregator, such as a reseller, of a content delivery network (CDN). In one aspect, content requests to the CDN are processed in accordance with the virtual IP (VIP) address at which the request was received, according to a property template bound to the VIP where the template is selected by the customer and only involves discrete parameters for the reseller. In another aspect, cache fills of the network are processed without direct knowledge of the customer origin through a combination of some request attribute, e.g., alias host of the customer, and an attribute of the reseller to make a DNS request to a name server outside the CDN. Another aspect involves receiving a property template selection, an origin and an alias from a customer of the reseller, and providing appropriate DNS entries to validate the customer and provide origin information to the CDN.

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.

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.
