摘要： One embodiment provides a system that facilitates content negotiation in a content centric network. During operation, the system receives, by a content producing device, a packet that corresponds to a first interest, wherein an encoded name for the interest indicates a plurality of qualifiers for acceptable types of requested content, and wherein a name is a hierarchically structured variable length identifier which comprises contiguous name components. The system generates a first content object that satisfies one of the indicated plurality of qualifiers, wherein a name for the content object is the encoded name, and wherein a content object indicates data and a content type corresponding to the satisfied qualifier.

摘要： One embodiment provides a system that facilitates efficient and secure flow control based on a fragmentation protocol. During operation, the system receives, by an intermediate node, a first fragment which is a fragment of a content object that is fragmented into a plurality of fragments, wherein the plurality of fragments includes at least one named fragment, which indicates a name associated with the content object, the name being a hierarchically structured variable-length identifier that comprises contiguous name components ordered from a most general level to a most specific level. The intermediate node detects a congestion, and sets an indicator for congestion notification in the received fragment. The intermediate node forwards the received fragment, and drops a second fragment received after the forwarded fragment.

摘要： One embodiment provides a system that facilitates an efficient transport protocol. During operation, the system receives a first interest which indicates a query for optimal transport parameters, wherein a name for an interest is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level, wherein the query is based on a name prefix that includes one or more contiguous name components. The system computes the optimal parameters based on historical information associated with the name prefix. The system transmits a first response which includes the computed optimal parameters to a requesting entity, thereby facilitating a transport protocol which increases network efficiency.

摘要： One embodiment provides a system that facilitates a single interface for file I/O and network communication. During operation, the system receives from a local application a first command to create content. The first command includes a content name and access control information that indicates how the content may be accessed. The content name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. The system creates a first manifest which is a content object that indicates a set of content objects by a name and a digest. The first manifest name is the content name corresponding to the first command, and access to the manifest is based on the access control information included in the first command. The system transmits to the local application the first manifest and an indicator of success for creating the first manifest.

摘要： One embodiment provides a system that deletes cached content. During operation, the system generates, by a content producing device, a content object packet that includes a name for the content object and a deletion identifier that is used to verify a subsequent deletion command. The system receives a notification message that includes a routable prefix for a router and indicates that the router has cached the content object packet. The system stores in a data structure a mapping between the routable prefix, the name, and a previously generated deletion token which is used as a pre-image of the deletion identifier. In response to determining a condition to delete the cached content object packet, the system transmits a deletion command based on the routable prefix, wherein the deletion command includes the deletion token and the name for the cached copy of the content object packet to be deleted.
