Patent number: 9210081Abstract: The solution described herein provides systems and methods for the interoperability of network processing programs that process network packets at different levels of the network stack. This solution bridges the communications of a network packet between a first network processing program operating at a first level of a network stack in an intermediary and a second network processing program operating at a second level of the network stack of the intermediary. The first network processing program may modify an incoming network packet so that the packet may traverse the network stack to an upper level of the stack to the second network processing program. After processing the network packet at the upper layers of the stack or by the second network processing program, the first network processing program modifies the network pack in order to transmit the packet to the intended destination while traversing the intermediary.Type: GrantFiled: October 24, 2014Date of Patent: December 8, 2015Assignee: CITRIX SYSTEMS, INC.Inventors: Sanjay Chadda, Allen R. Samuels, Dan S. Decasper, Zubin Dittia, Shiva Ankam

Patent number: 8786473Abstract: 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 also use application specific parsing to improve the length and number of compression history matches. Further, by sharing compression histories and compression history indexes across multiple devices, devices can utilize data previously transmitted to other devices to compress network traffic. Any combination of the systems and methods may be used to efficiently find long matches to stored data, synchronize the storage of previously sent data, and share previously sent data among one or more other devices.Type: GrantFiled: October 18, 2011Date of Patent: July 22, 2014Assignee: Citrix Systems, Inc.Inventors: Allen R.

Patent number: 7876712Abstract: A method and apparatus for processing an overlay network infrastructure. In one embodiment, the method comprises a plurality of transparent access points (TAPs). Each TAP is communicably coupled between one or more clients and servers and a wide area network (WAN) to enable the one or more clients to communicate with the one or more servers, and is coupled to other of the TAPs via permanently, established secure links. The overlay network also comprises a controller coupled to each of the TAPs via a secure connection to configure the TAPs with information to enable each TAP to know what services are available and from which of the TAPs each of the services can be accessed.Type: GrantFiled: September 23, 2009Date of Patent: January 25, 2011Assignee: Citrix Systems, Inc.Inventors: Dan Decasper, Zubin Dittia, Prashanth Mundkur, Rajib Ghosh
