Abstract

Virtual local area network (VLAN) identifications (VIDs) used in a local area network (LAN) are identified. The LAN is connected to a connection-oriented wide area network (WAN). Each VLAN supports multiple priorities. For each VID, each of the priorities is mapped to a service type available in the WAN. Virtual connections (VCs) are set up based using a combination of the VID and the mapping of the priorities to the service types.
