  • Transmission apparatus operation for VPN optimization by defragmentation and deduplication method
    Patent number: 8831030
    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.
    Type: Grant
    Filed: August 6, 2013
    Date of Patent: September 9, 2014
    Assignee: Barracuda Networks, Inc.
    Inventors: Subrahmanyam Ongole, Sridhar Srinivasan

  • Reception apparatus for VPN optimization by defragmentation and deduplication and method
    Patent number: 8571042
    Abstract: A reception 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 from a primary apparatus. Only data paragraphs which are not previously cached at satellite are received. The data object is integrated from stored and newly transmitted data paragraphs and transmitted to its destination IP address.

  • VPN optimization by defragmentation and deduplication apparatus and method
    Patent number: 8050251
    Abstract: An 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 between a primary and a satellite apparatus. Only data paragraphs which are not cached at both the primary and satellite are transferred. The data object is integrated from data paragraphs stored in cache and transmitted to its destination IP address.
