Abstract: One embodiment provides a system for facilitating scheduling of interests in a CCN. The system determines, by a scheduler component, network properties associated with name prefixes of interests transmitted by a plurality of local applications, 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, and wherein a name prefix includes one or more contiguous name components. The system generates a first interest which indicates a command to set a window size for a transport stack associated with a respective local application based on the network properties. The system transmits the first interest to a component associated with the transport stack, which causes the component to set the window size for the transport stack, thereby facilitating scheduling of interests based on the network properties.

Abstract: One embodiment provides a system that facilitates a secure encryption proxy in a content centric network. During operation, the system receives, by an intermediate router from a content-consuming computing device, a first interest that includes a first name, signaling information encrypted based on a signaling key, and an inner interest encrypted based on an encryption key. The inner interest includes a name for a manifest that represents a collection of data. The intermediate router does not possess the encryption key. The system generates one or more interests for the data represented by the manifest. The system transmits to the content-consuming computing device a content object received in response to a generated interest, wherein the intermediate router transmits the responsive content object without receiving a corresponding interest from the content-consuming computing device, thereby facilitating reduced network between the content-consuming computing device and the intermediate router.

Abstract: One embodiment provides a transport-framework system that facilitates command messages to be communicated in a layer-agnostic manner. During operation, the system generates, by a component of a stack of communication modules, a first command message for a target entity. The first command message includes a name unique to the target entity, and the stack does not require a respective communication module to communicate only with a layer above or below thereof. The component sends the first command message to the target entity by inserting the first command message into a queue corresponding to the component. The component can also receive a second command message from a sending entity via a queue corresponding to the sending entity, and the second command message includes a name unique to the component. This facilitates command messages to be communicated in a layer-agnostic manner.

Abstract: One embodiment provides a system that facilitates efficient communication based on a forwarding information base (FIB). The system receives, by an intermediate node, a first interest which includes a name and maximum interest information which indicates whether to forward a subsequent interest with a same name prefix as the first interest. In response to obtaining a first entry from a FIB based on the name for the first interest, the system adds to the first entry, for an outgoing interface corresponding to an arrival interface of the first interest, the maximum interest information included in the first interest as an interest limit for the first entry. In response to determining that the interest limit for the first entry is reached, the system refrains from forwarding the subsequent interest, thereby facilitating the intermediate node to manage traffic based on information in the forwarding information base provided by a content producer.

Abstract: One embodiment provides a system that facilitates routable prefix queries in a CCN. During operation, the system generates, by a client computing device, a query for one or more indices based on a name for an interest, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. An index indicates a number of the contiguous name components beginning from the most general level that represent a routable prefix needed to route the interest to a content producing device that can satisfy the interest. In response to the query, the system receives the one or more indices, which allows the client computing device to determine a remaining number of name components of the interest name which can be encrypted, thereby facilitating protection of private communication in a content centric network.

Abstract: One embodiment provides a system for facilitating efficient communication of a collection of interests. During operation, the system receives, by an intermediate node, a first packet which has a name and a first nonce, wherein the first packet indicates a set of member interests, wherein a member interest has a name. In response to not obtaining a matching entry in a pending interest table based on the name for the first packet, the system creates a new entry in the pending interest table, wherein an entry includes a second nonce, a reference count, and a set of arrival nonces and corresponding arrival interfaces. The system sets the new entry's second nonce to a new nonce, and sets the new entry's reference count to a number of member interests indicated in the first packet. The system forwards the first packet, wherein the first nonce is replaced with the new nonce.

Abstract: 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.

Abstract: 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.
