Patent ID: 8571042

Claim:
A method for operation of a reception apparatus to receive defragmented and de-duplicated data object packets, the apparatus comprising: at least one network interface, a primary cache store, a primary transfer diary store, and a data object integrator; the method comprising: receiving and storing into primary cache store at least one data paragraph corresponding to a hash; storing into primary transfer diary store a source of the data paragraph corresponding to the hash and a time of most recent usage; and receiving a data object integration packet containing at least one hash and a remainder; integrating a data object by reading data paragraphs from the primary cache store and concatenating the data paragraphs and the remainder; delivering the reconstituted data object to its destination; and within a circuit for reception of a pending transfer: receiving a hash from a pending transfer transmitter corresponding to a data paragraph, determining from a primary transfer diary store that the hash is already stored in a primary cache store, and transmitting to a satellite transfer store an update on the status of the hash, whereby the satellite transfer diary store changes the status of a pending transfer from pending to past and utilization of a communications channel is optimized by de-duplication.
