Abstract: Aspects of the present disclosure involve systems and methods for monitoring and quantifying the performance of a content delivery network (CDN) from a client side perspective based on server side events. In one particular embodiment, one or more content servers of the CDN may provide connectivity or other performance information to a collector device or site. This information may be reported by each of the content servers for each request for content received at the server. The collector site may then store the received performance information in a database for analysis by one or more 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: Aspects of the present disclosure involve systems, methods, computer program products, and the like, for a content delivery network (CDN) architecture utilizing one or more proxy cache devices between a requesting device and an edge cluster of the CDN. The proxy cache device is a relatively high speed device compared to various possible devices making up one or more edge clusters. Thus, if the proxy has cached the requested content, it is capable of directly servicing the client content request at a faster rate than providing the content from the edge cluster. Otherwise, the proxy cache may request the content from an edge cluster and store the content for quick retrieval in response to additional requests for the content. In one embodiment, the proxy cache may perform an analysis of the request or a series of requests to determine if the content is cached at the proxy cache device.

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.

Abstract: Provided is a content delivery method and architecture for ways to improve the caching of content at one or more content providing devices of a Content Delivery Network (CDN). In particular, systems and methods are disclosed that vary the requirements to store resources or content within a caching device using a dynamic popularity threshold. This popularity threshold may be varied based on a measured fullness of the storage capacity of the cache device. In another example, the dynamic popularity threshold may be further varied based on a cache pressure, which is an indication of how often the cache replaces stored items with new items. The adjustment to the popularity threshold for caching particular content at the caching device may thus be based on a number of requests for content received at the device to tune the caching procedure for a particular region of the CDN.

Abstract: A content delivery network with at least one first content server bound to a first domain associated with a first characteristic (e.g., popular) associated with content servable from the content delivery network. The content delivery network includes at least one second content server bound to a second domain associated with a second characteristic (e.g., unpopular) associated with content servable from the content delivery network. At least one processing device including computer executable instructions for receiving a request to provide an embedded resource including either a first host name associated with the first domain or a second host name associated with the second domain.
