Abstract
A transmission apparatus for optimizing a virtual private network operates by defragmenting and deduplicating 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 are not previously cached at each satellite are transferred.
