  • Obtaining high availability using TCP proxy devices
    Patent number: 8432799
    Abstract: The present invention relates to increasing performance of Wide Area Network (WAN) communications and in particular to a redundant proxy device associated with one end of a transport layer connection that monitors packet traffic and selectively reroutes packets to a proxy application.
    Type: Grant

  • Architecture for efficient utilization and optimum performance of a network
    Patent number: 7639700
    Abstract: An architecture for optimizing network communications that utilizes a device positioned at two edges of a constrained Wide Area Network (WAN) link. The device intercepts outgoing network packets and reroutes them to a proxy application. The proxy application uses persistent connections with a network accelerator device at the other end of the persistent connection. The proxy applications transmit the intercepted data after compressing it using a dictionary-based compression algorithm. Packet mangling may involve spoofing the connection request at each end node; a proxy-to-proxy communication protocol specifies a way to forward an original address, port, and original transport protocol information end to end. The packet mangling and proxy-to-proxy communication protocol assure network transparency.

  • Accelerating network performance by striping and parallelization of TCP connections
    Patent number: 7286476
    Abstract: An architecture for optimizing network communications that utilizes a device positioned at two edges of a constrained Wide Area Network (WAN) link. The device intercepts outgoing network packets and reroutes them to a proxy application. The proxy application uses multiple, preferably persistent connections with a network accelerator device at the other end of the persistent connection. The proxy applications transmit the intercepted data. Packet mangling may involve spoofing the connection request at each end node; a proxy-to-proxy communication protocol specifies a way to forward an original address, port, and original transport protocol information end to end. The packet mangling and proxy-to-proxy communication protocol assure network layer transparency.
