SYSTEM AND METHOD FOR MANAGING BANDWIDTHS OF VPNS

摘要

PURPOSE: A system and a method for managing bandwidths of VPNs(Virtual Private Networks) are provided to control bandwidths of a data traffic over VPNs. CONSTITUTION: A data traffic of a VPN is classified into different flows(S10). Current bandwidth usage is monitored by at least one of the flows(S20). The current bandwidth usage is compared with a predetermined threshold of the flow(S30). If the current bandwidth usage exceeds the predetermined threshold of the flow, the bandwidth control operation for the flow is performed(S40).
