This paper presents a novel lossless data compression device that extends enterprise network to branch offices by integrating multiple communication technologies. The presented device incorporates Gigabit Ethernet, STM1/STM4/STM16 interfaces for WAN connectivity, fiber channel interfaces for storage area network and 10G Ethernet interface for enterprise network connectivity. The device implements a novel architecture that implements the LZ77 lossless data compression algorithm in hardware. The high throughput data compression architecture enables the interfacing of the diverse high-speed communication technologies besides preserving the channel bandwidth for accommodating multiple applications. The device finds consumer applications to optimize WAN bandwidth, healthcare, media&broadcasting and storage area networks (SAN).
