Abstract: In one embodiment, a caching resolver receives a name server query from an end device for an Internet Protocol (IP) address for a hostname, and determines whether the hostname requested is in an access control list (ACL). In response to the hostname being in the ACL, the caching resolver examines a received response to the name server query for the hostname, wherein the received response contains a particular IP address for the hostname, and adds the particular IP address for the hostname to the ACL. In one embodiment, the ACL is local to the caching resolver, while in another embodiment, adding the particular IP address for the hostname to the ACL comprises sending a message to a remote ACL-maintaining device that maintains the ACL.

Abstract: One embodiment provides a system that facilitates synchronization collections of data between a local and a remote node by using exact match names. During operation, a local node receives an advertisement corresponding to a remote manifest at a remote node. A manifest represents a collection of content objects at a node. In some embodiments, a manifest corresponds to a root hash value that identifies the content objects of the collection. The local node determines that the local manifest and the remote manifest both indicate the same collection of content objects. The local node then determines if the content of the collections are different by comparing the root hash value of the local manifest with the root hash value of the remote manifest. Responsive to determining that the root hash values of the manifests are different, the local node retrieves the remote manifest by sending a request for the remote manifest.

Abstract: One embodiment provides a system that facilitates efficient aggregation of multiple interest messages for the same content from multiple predecessors. During operation, an intermediate node receives a first interest message from a predecessor node. The first interest indicates a name for a content object and a lifetime associated with the first interest. The intermediate node identifies an entry in a pending interest table that corresponds to the first interest and determines that the entry has not expired. The intermediate node determines whether a second interest message which indicates a same content object name as the first interest message has been received from the predecessor node. If so, it forwards the first interest. If not, it adds information associated with the predecessor node to the entry. The intermediate node determines a predecessor lifetime associated with the entry and also determines a maximum lifetime associated with the entry.

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.
