摘要： Methods and systems for storing and distributing content include executing storage rules against ingested content to determine in which of a plurality of storage systems to store the ingested content. A metadata collection that includes records corresponding to the stored content is maintained such that the content may be located by querying or otherwise searching the metadata collection. The metadata collection may be analyzed using various criteria to identify content to be migrated between different storage systems.

摘要： Aspects of the present disclosure involve systems, methods, computer program products, and the like, for providing failover and load clustering features to one or more proxy servers of a content delivery network (CDN). In one embodiment, one or more proxy servers may announce a virtual host internet protocol (IP) and, to provide a failover feature, two or more of the proxy servers may also announce a more generic virtual network IP address that includes a broader range of IP addresses associated with the virtual network IP address. In another embodiment, each of the proxy servers in communication with the router may announce a generic IP network address to the router. In response to receiving a request for content from an end user of the CDN, the router may select a proxy server and load balance the received requests among the proxy servers.

摘要： Aspects of the present disclosure include a content delivery network (CDN) for delivering content associated with a plurality of different types of applications/devices. Using a CDN flow application, a plurality of network flow parameters are generated for content delivery unique to different types of applications or devices. The network flow parameters include customized data transmission rates. The network flow parameters include predetermined settings for transmission control protocol (TCP) connections between the CDN and devices using a TCP flow control mechanism. Upon receiving a content request, the CDN fulfills the content request based upon first network flow parameters. The network flow parameters may be adjusted for each of the plurality of different types of applications/devices. The network flow parameters may be generated based upon requests or based upon the performance of each of the plurality of applications/devices.

摘要： 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.

摘要： A server in a content delivery (CD) network that distributes content on behalf of one or more subscribers. Responsive to a request from a client for a particular resource, if the particular resource is already in a cache on the server, serving the particular to the client from the cache; otherwise if the particular resource is not already cached on the server, when a count value exceeds a first threshold value, obtaining, caching, and serving the particular resource. When the count value is less than a second threshold value, obtaining and serving the particular resource. When the count value is: (i) not less than the second threshold value, and (ii) not greater than the first threshold value, then obtaining the particular resource and selectively caching the particular resource; and serving the particular resource to the client.

摘要： 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 an HTML document. Delivering, such as in response to request from a browser, the content resource with the modified embedded resource.

摘要： 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.
