Content router notification

A method for communicating an outgoing command from a content router to a content node using a gateway, the method comprising, at the gateway:

• receiving, from the command memory of the content router, a notification signal, wherein the received notification signal indicates a content type of an outgoing command in the command memory of the content router available for the content node;
• sending, to the command memory of the content router, a request for the outgoing command, the request including the content type;
• receiving, from the command memory of the content router, a response including the outgoing command;
• preparing, in response to receiving the outgoing command, an outgoing message including the outgoing command;
• and
• sending, to the content node, the message including the outgoing command in a notification signal to the content node.

A computer-readable storage medium comprising program code for use in a gateway including processing logic for communicating an outgoing command from a content router to a content node, the computer-readable storage medium comprising:

• program code for receiving, from the command memory of the content router, a notification signal, wherein the received notification signal indicates a content type of an outgoing command in the command memory of the content router available for the content node;
• program code for sending, to the command memory of the content router, a request for the outgoing command, the request including the content type;
• program code for receiving, from the command memory of the content router, a response including the outgoing command;
• program code for preparing, in response to receiving the outgoing command, an outgoing message including the outgoing command;
• and
• program code for sending, to the content node, the message including the outgoing command in a notification signal to the content node.

A content router for communicating outgoing commands from the content router to a plurality of content nodes, the content router comprising:

• command memory for holding incoming and outgoing commands;
• and
• processing logic, coupled to the command memory, for:
• saving to the command memory an incoming command received from a first content node and associated with a content type;
• selecting a set of destination content nodes based on the content type and one or more routing parameters;
• and
• for each of the selected destination content nodes:
• saving an outgoing command to the command memory;
• sending, to a gateway, a notification signal, wherein the sent notification signal indicates the content type of the outgoing command in the command memory available for the destination content node;
• receiving, from the gateway, a request for the outgoing command, the request including the content type;
• sending, to the gateway, a response including the outgoing command;
• receiving, from the gateway, a request including an acknowledgement indicating that the outgoing command may be discarded;
• removing the outgoing command from the command memory;
• and
• sending, to the gateway, a response including an indication that the request including the acknowledgement was received by the content router.

A method for communicating an outgoing command from a content router to a content node, the method comprising, at the content router:

• sending, to a gateway, a notification signal, wherein the sent notification signal indicates a content type of an outgoing command in the content router available for the content node;
• receiving, from the gateway, a request for the outgoing command, the request including the content type;
• sending, to the gateway, a response including the outgoing command;
• receiving, from the gateway, a request including an acknowledgement indicating that the outgoing command may be discarded;
• and
• sending, to the gateway, a response including an indication that the request including the acknowledgement was received by the content router.

• program code for sending, to the gateway, a response including the outgoing command;
• program code for receiving, from the gateway, a request including an acknowledgement indicating that the outgoing command may be discarded;
• and
• program code for sending, to the gateway, a response including an indication that the request including the acknowledgement was received by the content router.
