Patent Images
1. A method of determining forwarding treatment for an Ethernet frame received at a node in a provider network comprising:
- determining, based on information in a header of the Ethernet frame, a Class of Service Identifier to associate with the Ethernet frame;
determining an identity of an Ethernet Virtual Connection (EVC) to associate with the Ethernet frame;
selecting, based on the identity of the EVC, a service class map from a plurality of service class maps, where each service class map associates forwarding treatments with Bandwidth Profiles; and
determining a forwarding treatment for the Ethernet frame based on the Class of Service Identifier.

Abstract
Numerous enhancements to metro Ethernet network (MEN) services include an enhancement of the overall MEN Quality of Service (QoS) architecture, an enhancement to classification at the provider edge, the use of Ethernet QoS classes, enhancements to policing and marking at ingress provider edge equipment, the provision of traffic management functions at egress provider edge equipment, the use of multiple Ethernet virtual connections (EVCs) and Aggregate EVCs, an enhancement to QoS across an external network-network interface and an enhancement to treatment of Ethernet service frames in a core network.
