Abstract

A method and system for authorizing traffic flows in a computer network. The method including: receiving a packet from a traffic flow sent by a sender; determining whether the traffic flow has been previously authorized; if the traffic flow has not been previously authorized: determining a subscriber associated with the traffic flow, based on the data retrieved from the packet; requesting authorization from an authorization server based on the subscriber and the data retrieved from the packet; upon receiving a response from the authorization server, sending at least three duplicate acknowledgments to the sender, to generate a retransmission in advance of the standard retransmission timing; otherwise, if the traffic flow has been previously authorized, allowing the packet to continue to a destination.
