  • Patent number: 7613131
    Abstract: 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.

  • Publication number: 20090234947
    Abstract: A method and apparatus for displaying locally stored content objects is disclosed. In one embodiment, the method comprises receiving a message containing one or more parameters indicative of one or more characteristics of a client, and sending one of a plurality of groups of one or more content objects from a set of content objects to the client based on the one or more parameters, wherein each of the plurality of groups is suited for use with clients having a different set of one or more parameters.

  • Publication number: 20090234966
    Abstract: 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.

  • Patent number: 7581005
    Abstract: The solution of the present invention provides systems and methods for preserving transport layer header options traversing network devices that terminate transport layer connections. The solution described herein provides a bi-directional intelligent proxying system by which a proxy client exchanges transport layer option information with a proxy server via an application layer protocol. The proxy server, which may be in the form of an appliance, re-injects the transport layer options received from the client into the appropriate network packets communicated on the intended network. Likewise, the proxying appliance can inform the proxy client of transport layer options received from the network, such as via a server. With this solution, devices that transmit control information, exchange communications or other functionality via transport layer options may continue to operate in conjunction with transport layer terminating devices.

  • Publication number: 20090067440
    Abstract: 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.
