Abstract: A transmission apparatus operation method for optimizing a virtual private network operates by defragmenting and de-duplicating transfer of variable sized blocks. A large data object is converted to a plurality of data paragraphs by a fingerprinting method. Each data paragraph is cached and hashed. The hashes are transmitted to at least one satellite apparatus. Only data paragraphs which were not previously cached at each satellite are transferred.
