Abstract: Network traffic may be logged and analyzed to perform accounting on amount of a chargeable network resource that is consumed fulfilling requests for different clients or for different servers. A network device may report network traffic to a server through NetFlow data records. The network traffic records may be generated by monitoring traffic through either the ingress ports or the egress ports of a network device. Monitoring only ingress or egress ports reduces or eliminates duplication of network traffic counting. Two-directional network traffic may be monitored by transmitting traffic in one direction through a first interface and in a second direction through a second interface.

Abstract: Network traffic may be logged and analyzed to perform accounting on amount of a chargeable network resource that is consumed fulfilling requests for different clients or for different servers. A network device may report network traffic to a server through NetFlow data records. The NetFlow data records may then be analyzed to remove or correct packets containing an incorrect physical address, such as when the logged packets have a recorded physical address equal to the physical address of the network device logging the traffic.

Abstract: Network traffic may be logged and analyzed to perform accounting on amount of a chargeable network resource that is consumed fulfilling requests for different clients or for different servers. A network device may report network traffic to a server through NetFlow data records. The network traffic may be analyzed by identifying physical addresses recorded for transmitted data in the NetFlow data records. The physical addresses may be correlated to computer names, which are then billed for the network traffic.
