摘要： Various embodiments relate to a method performed by a router. The method may include: receiving, at a first line card of the router, a request for content having a content identifier; determining a second line card that is responsible for the content identifier; switching the request for content to the second line card; and updating a pending interest table at the second line card based on the request for content. Various embodiments relate to a router for content based routing that receives a plurality of requests for contents including a content identifier. The router may include: a fabric switch; and a plurality of line cards interconnected by the fabric switch, each line card includes a network processor and a pending interest table configured to store entries for a subset of the requests defined by the content identifier.

摘要： A method for reducing content redundancy in CCN includes distributing named media content or another type of content from sources to consumers through host devices and intermediate devices via a communication network using object messages that carry fingerprint names and data chunks. The named content is divisible into data chunks represented by fingerprint names such that a content fingerprint list for content identifies data chunks for the content using fingerprint names. The fingerprint names are based on content data in the data chunk such that data chunks with the same content data for the named content and for other content are represented by the same fingerprint name and data chunks with different content data are represented by different fingerprint names. A subsystem associated with the method includes consumer and source communication modules; a local storage device; message routing, fingerprint list processing, and object caching modules; and a message processing controller.
