  • Patent number: 9258230
    Abstract: A system and method for reconfiguring a TCP window in a switch of a network system, where the size of the window is determined based on the operating speed of a work station to which data packets in the window are being sent and the size of the switch buffer. The algorithm includes establishing a connection between a server and the station, where the connection includes TCP data packets. The algorithm identifies a TCP window size requested by the station, and identifies the connection speed of the station in the switch. The algorithm then modifies the TCP window size of the connection if the identified TCP window size does not support the connection speed and the size of the buffer. The algorithm also changes the TCP check-sum based on the new TCP window size.

  • Patent number: 9049000
    Abstract: There exists a need to reduce re-transmission delays in real time feeds (such as video) by sending the packet with sufficient repair/recovery information inside the packet container so the relaying stations and/or the receiving devices can fix errors in transmission by perusing the contents of the packet and the repair information, and modify the packet and then relay it. By providing the relaying station the ability to fix the error, retransmission of the packet is avoided along each relay station along the network path from source to destination and also by receiving devices that would otherwise request a re-transmission. This application teaches a method so real time streams (e.g. video) may be more efficiently transported over a CSMA based network.
