Application ID: 15213838

Base Claim:
1. A computer readable storage medium, tangibly embodying a program of instructions executable by the computer for data object routing based on a named data object request in a named data network including a plurality of routers, the program of instructions, when executing, performing the following steps: 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.

Claim 2:
2. The computer readable storage medium of claim 1 , wherein the program of instructions, when executing, further performs the steps of: 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 a location of the data object named by the named data object request at a third one of the routers is known; wherein, if the location of the data object named by the named data object request at the third one of the routers is known and if the location of the third router is closer to the first router than the location of the second router, then: routing by the first router the named data object request towards the location of the third router instead of the location of the second router.
