The access control systems (ACS) are useful to improve the Quality of Service solutions. These systems are generally based on delay, jitter or packet loss, employing more of these criteria to maintain the required quality of service requiring for voice or video sessions. We propose an ACS that employs packet loss between probes that send an end-to-end test stream before accepting additional sessions. We used Ethernet as our transport network because the 803.3ae is widely used in metropolitan area networks. This paper presents how the ACS will interoperate with MPLS and describe the improvements related to its use in a metropolitan Ethernet network.
