Method and apparatus for pushing data in a content-centric networking (CCN) network

A method for pushing data in a Content-Centric Networking (CCN) network, the method comprising:

• receiving a message from a source at an input interface of a node device in the CCN network, the message based on a CCN protocol, wherein a content object in the CCN protocol is represented according to one or more fields;
• determining that the message is received as an interest-notification message according to a Type field, a Content Name field, and a Cacheable Object field included in the message, the Type field indicating that the received message is for pushing data within the CCN network, the Content Name field associating a hierarchical name to the data being pushed within the CCN network, the Cacheable Object field including the one or more fields for a cacheable object representing the data being pushed within the CCN network;
• extracting the cacheable object from the received message in response to the received message determined to be the interest-notification message;
• and
• placing the cacheable object in a cache at the node device for retrieval by an interest message.

An apparatus for pushing data in a Content-Centric Networking (CCN) network, the apparatus comprising:

• an input interface configured to receive a message from a source, the message based on a CCN protocol, wherein a content object in the CCN protocol is represented according to one or more fields;
• a memory configured to store data and instruction code;
• a processor, upon executing the instruction code, configured to:
• determine that the message is received as an interest-notification message according to a Type field, a Content Name field, and a Cacheable Object field included in the message, the Type field indicating that the received message is for pushing data within the CCN network, the Content Name field associating a hierarchical name to the data being pushed within the CCN network, the Cacheable Object field including the one or more fields for a cacheable object representing the data being pushed within the CCN network,
• extract the cacheable object from the received message in response to the received message determined to be the interest-notification message;
• and
• a content store configured to receive and cache the cacheable object for retrieval by an interest message.
