  • Method and apparatus to permit data transmission to traverse firewalls
    Patent number: 7602784
    Abstract: Currently data transmission over the Internet between two client computers where both client computers are protected by firewalls is problematic, since firewalls block incoming packets. A method is provided for permitting packet based data transmission between a first client computer C1 protected by a first NAPT or NAT firewall and a second client computer C2 protected by a second NAPT or NAT firewall to traverse the first and the second firewalls. The method can also be applied to other devices, such as routers, using NAT or NAPT.
    Type: Grant

  • Method and system for controlling the rate of transmission for data packets over a computer network
    Publication number: 20040017773
    Abstract: The present invention provides a window-based method for controlling the rate of data transmission for computer software applications transmitting data using packet switched protocols. The method is suitable for real-time applications, such as Internet video conferencing, which require low transmission latency, and which can tolerate some level of packet loss.
