1. A method implemented in a computer system network for data object routing based on a named data object request in a named data network including a plurality of routers, the method comprising: receiving at a first one of the routers the named data object request; determining by the first router if the data object named by the named data object request is in a cache of the first router; if the data object named by the named data object request is in the cache of the first router, responding by the first router with the data object; if the data object named by the named data object request is not in the cache of the first router, determining by the first router if an alias copy of the data object named by an alias associated with the named data object is in the cache of the first router; if the data object named by the named data object request is not in the cache of the first router and if an alias copy of the data object named by an alias associated with the named data object is in a cache of the first router, responding by the first router with the alias copy; if the data object named by the named data object request is not in the cache of the first router and if an alias copy of the data object named by an alias associated with the named data object is not in the cache of the first router, determining by the first router if a location of an alias copy of the data object at a second one of the routers is known; and if the data object named by the named data object request is not in the cache of the first router and if an alias copy of the data object named by an alias associated with the named data object is not in the cache of the first router and if the location of the alias copy of the data object at the second one of the routers is known, routing by the first router the named data object request towards the location of the second router.
