Abstract
This invention discloses a method for delay monitoring, policing and billing the data packet traffic in a packet switching network where the switches maintain a common time reference. This invention enables designated points inside the network to ascertain the level of packet traffic in predefine time intervals, and control the flow of packets and bring it back to predetermined levels in cases where the traffic volume exceeds predetermined levels. The information collected by the designated points facilitates billing for Internet services based on network usage, and identification of faulty conditions and malicious forwarding of packets that cause excessive delay beyond predetermined value.
