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. The local node determines which content objects identified in the remote manifest are different from the content objects identified in the local manifest. The local node transmits a set of interests for the content objects that are different and receives the requested set of content objects, thereby facilitating synchronization of content objects associated with the manifests at both the local and remote node. |
