Patent number: 8908700Abstract: 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: September 7, 2007Date of Patent: December 9, 2014Assignee: Citrix Systems, Inc.Inventors: Sanjay Chadda, Allen Samuels, Dan DeCasper, Zubin Dittia, Shiva Ankam

Patent number: 8352605Abstract: 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, compression history indexes and caches 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: December 29, 2010Date of Patent: January 8, 2013Assignee: Citrix Systems, Inc.Inventors: Allen Samuels, Richard Jensen, Zubin Dittia, Dan Decasper, Michael Osviannikov, Robert Plamondon

Publication number: 20120047339Abstract: A computing device executing a reliable cloud storage module divides data into a first data block and a second data block. The computing device stores the first data block in a first storage cloud provided by a first storage service, and stores the second data block in a second storage cloud provided by a second storage service. The computing device thereafter receives a command to read the data. In response, the computing device retrieves the first data block from the first storage cloud and the second data block from the second storage cloud. The computing device then reproduces the original data from the first data block and the second data block.Type: ApplicationFiled: August 20, 2010Publication date: February 23, 2012Inventors: Dan Decasper, Allen Samuels, Jonathan Stone

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

Patent number: 7664857Abstract: The solution of the present invention provides systems and methods for encoding information into an Internet Protocol identification field (IPID) of an IP layer header of a network packet in a manner acceptable to many or all of the network devices that encounter the encoded packet. In one embodiment, the solution described herein encodes the IP identification field of the IPID header with information to be communicated between devices. Appliances may use the encoded IP field as a signal or a means for a low-bandwidth subcarrier of data between the appliances that is transparent to any intervening network equipment. For example, the encoded field may be used to announce or probe the presence of a device, a functionality or capability of device or to indicate a type or speed of a network connection of a port on a device.Type: GrantFiled: March 12, 2007Date of Patent: February 16, 2010Assignee: Citrix Systems, Inc.Inventors: Mike Ovsiannikov, Dan Decasper, Robert Plamondon, Allen Samuels
