Systems and methods of storing previously transmitted data and using it to reduce bandwidth usage and accelerate future communications are described. By using algorithms to identify long compression history matches, a network device may improve compression efficiently and speed. A network device may...http://www.google.de/patents/US20090234966?utm_source=gb-gplus-sharePatent US20090234966 - SYSTEMS AND METHODS FOR SHARING COMPRESSION HISTORIES BETWEEN MULTIPLE DEVICES
