Systems and methods for content delivery control in a cooperative delivery system are disclosed. A rules repository stores control parameters. A content delivery network is configured to receive a request for a content object from an end-user system; receive from the rules repository a control parameter where the control parameter provides information about delivery and/or caching the content object; insert a string into a uniform resource identifier (URI) or response header for the content object; and transmit the response to or through a terminal network. The terminal network receives the response; identifies the string; identifies the control parameter; and processes delivery or storage of the content object based on the control parameter.

Delivery control for cooperative delivery systems

Techniques for modifying the performance of a transport layer protocol in response to a request for content are disclosed. A connection can be established between a content distribution server and an end user computer according to preconfigured parameters. When a request for content is received over the connection, the content distribution server can determine one or more parameters relating to the performance of the connection using information from the request. The content distribution server can modify the connection at the transport layer according to the one or more parameters. Thereafter, the transport layer can manage delivery of the requested content to the end user computer in accordance with the modified parameters. In various embodiments, the content distribution server includes a modified TCP protocol stack which adjusts timing, pacing, and buffer allocation associated with a connection in response to requests from an application-layer data source.

Conditional protocol control

In one embodiment, a system for adapting the interoperation of nodes in an information processing system is disclosed. The system includes a protocol handler, a protocol attribute information store and a protocol attribute selector. The protocol handler manages a first connection and a second connection over the network using a protocol. The protocol attribute information store holds a plurality of attributes. The protocol attribute selector evaluates first information related to a first connection, utilizes the protocol attribute information store to determine first protocol attributes corresponding to the first connection, and communicates the first attributes for the first connection to the protocol handler. Additionally, the protocol attribute selector evaluates second information related to a second connection, utilizes the protocol attribute information store to determine second attributes corresponding to the second connection, and communicates the second attributes for the second connection the protocol handler. The protocol handler uses first attributes for the first connection and second attributes for the second connection.
