    Abstract: An Ethernet Metropolitan Area Network provides connectivity to one or more customer premises to packet-bases services, such as ATM, Frame Relay, or IP while advantageously providing a mechanism for assuring security and regulation of customer traffic. Upon receipt of each customer-generated information frame, an ingress Multi-Service Platform (MSP) “tags” the frame with a customer descriptor that specifically identifies the recipient customer. In practice, the MSP tags each frame by overwriting the Virtual Local Area Network (VLAN) identifier with the routing descriptor. Using the customer descriptor in each frame, a recipient Provider Edge Router (PER) or ATM switch can map the information as appropriate to direct the information to the specific customer. In addition, the customer descriptor may also include Quality of Service (QoS) allowing the recipient Provider Edge Router (PER) or ATM switch to vary the QoS level accordingly.

    Abstract: A new type of data transport service which uses a frame relay layer 2 data link connection identifier (DLCI) to select among various service types, feature sets, and/or closed user groups (CUGs). A layer 3 address may be extracted from a layer 2 frame, and the layer 3 address information may be used to route a data packet over a packet-switched network according to the service classes, feature sets, and/or CUGs selected. At the destination, the layer 3 data packet may again be enclosed in a layer 2 frame with a DLCI indicating the service classes, features sets, and/or CUGs. Because the use of conventional permanent virtual circuits (PVCs) is not required in aspects of the invention, new methods of measuring and managing network traffic are presented.
