Proactive data object replication in named data networks

摘要

The present disclosure relates generally to the field of proactive data object replication in named data networks. In various examples, proactive data object replication may be implemented in one or more named data networks in the form of systems, methods and/or algorithms.

主权项

1. A computer readable storage device, tangibly embodying a program of instructions executable by the computer for replicating at least one data object that is hosted in a named data network, the program of instructions, when executing, performing the following steps:
determining, with the computer system, a popularity of the data object that is hosted in the named data network; determining, with the computer system, a number of replicas of the data object to be created, wherein the determination of the number of replicas to be created is based at least in part upon the determined popularity of the data object; and replicating, with the computer system, the data object to create the determined number of replicas; wherein the program of instructions, when executing, further selects a replication target pool based at least in part upon a congestion level of the named data network; wherein the replication target pool comprises possible elements of the named data network on which a respective replica may be placed; wherein the replication target pool comprises a subset of the elements of the named data network; wherein a replication target is one of the elements of the named data network in the replication target pool; and wherein a replication target for a respective replica is randomly selected from among the replication target pool.
