  • Publication number: 20080043617
    Abstract: A method for determining service availability using a plurality of weighted monitoring agents includes: establishing, by an appliance, a plurality of agents, the plurality of agents monitoring a service executing on a server, and each agent having an assigned weight; computing, by the appliance, a sum of the assigned weights of the agents reporting the service as currently operational; determining, by the appliance, the sum falls below a given threshold; and transmitting, by the appliance, an indication that the service is unusable. Corresponding systems are also described.

  • Publication number: 20080034072
    Abstract: Methods for redirecting, on a client, a communication of the client to a server to upon determining the server is not useable to communicate to the client include the steps of: establishing, by an client agent on a client, a transport layer connection between the client and an intermediary appliance, the intermediary appliance providing access to one or more servers; receiving, by the client agent from the intermediary appliance, address information identifying at least one of the one or more servers available to communicate; determining, by the client agent, the transport layer connection is unusable to communicate; establishing, by the client agent, a second transport layer connection between the client and one of the identified available servers to bypass the appliance. Corresponding systems are also described.

  • Publication number: 20080034110
    Abstract: Methods for using a client agent to route client requests among a plurality of appliances using transport layer information include the steps of: establishing, by a client agent executing on a client, a first transport layer connection with a first appliance of a plurality of appliances, the first appliance providing access to one or more servers; establishing, by a client agent executing on the client, a second transport layer connection with a second appliance of a plurality of appliances, the second appliance providing access to one or more servers; intercepting, by the client agent, a packet transmitted by the client; selecting, by the client agent, one of the connections to transmit the intercepted packet based on a characteristic of at least one of: the transport layer connections, the plurality of appliances, or the servers; and transmitting the intercepted packet via the selected connection.

  • Publication number: 20080034119
    Abstract: Systems and methods are disclosed for communicating compressed and uncompressed content over a transport layer connection established by an appliance between a client and a server. One method comprises the steps of: establishing, by an appliance, a transport layer connection between a client and a server, and receiving, by the appliance, a first response from the server to a first client request, and a second response from the server to a second client request The first response and the second response has uncompressed data. The method includes transmitting, by the appliance, the first response to the client. The appliance identifies first type of compression from a plurality of compression types for compressing the second response to the client, compresses the second response based on the identified compression type, and transmits the compressed second response to the client.

  • Publication number: 20060253605
    Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment. The client-side acceleration functionality is provided by an acceleration program that performs a plurality of the following acceleration techniques in an integrated and efficient manner: 1) multi-protocol compression 2) transport control protocol pooling, 3) transport control protocol multiplexing 4) transport control protocol buffering, and 5) caching. The acceleration program establishes a transport layer connection between the client and server, and intercepts network packets at the transport layer.

  • Publication number: 20060248581
    Abstract: The present invention is directed towards systems and methods for dynamically redirecting on a client communications of the client with a server to bypass an intermediary that is determined to be unavailable for such communications. An acceleration program on the client establishes a transport layer connection between the client and server, and intercepts communications of the client to the server. The transport layer connection may be established via an intermediary, such as a gateway, proxy or appliance. If the client-side acceleration program determines the intermediary is not available for communicating by the client to the server, the acceleration program automatically establishes a second transport layer connection to the server in order to bypass the intermediary. The acceleration program then transmits the intercepted communications of the client via the second transport layer connection to the server.

  • Publication number: 20060200849
    Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment, the client-side acceleration functionality is provided by an acceleration program that performs a transport layer connection pooling technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server that can be used by multiple applications on the client, or that is otherwise shared among applications of the client. The acceleration program maintains the transport layer connection open to reduce the number of transport layer connection requests and number of transport layer connections established with the server for an application or multiple applications running on the client.

  • Publication number: 20060195605
    Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment, the client-side acceleration functionality is provided by an acceleration program that performs a transport layer connection buffering technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server and buffers requests of the client based on determining a difference between a rate of consumption of responses received by the client from a server and a rate of production of requests transmitted by the client to the server. As such, the acceleration program can throttle transmissions of the client if the client's rate of consumption falls behind the rate of submission of requests.

  • Publication number: 20060195840
    Abstract: The present invention is directed towards systems and methods for dynamically deploying and executing an acceleration program on a client to improve the performance and delivery of remotely accessed applications. The acceleration program of the present invention is automatically installed and executed on a client in a manner transparent to and seamless with the operation of the client. An appliance may intercept a request of the client to establish a communication session or connection with a server, and transmit the acceleration program to the client. In some cases, the appliance determines whether the application being accessed by the client can be accelerated and only provides the acceleration program if the application can be accelerated. Upon receipt of the acceleration program, the client automatically performs a silent installation of the acceleration program and executes the acceleration program upon completion of the installation.
