Abstract
Methods and systems for encapsulating and de-encapsulating a customer frame component of a Provider Backbone Bridging header are provided. The customer frame component includes a customer local area network identifier and a customer destination address. The customer frame component can be received at an ingress port of a network device for transmission. Header information can be determined from the customer local area network identifier and the customer destination address. A key can be set in the header information to a predefined value for a Provider Backbone Bridging protocol. A backbone service instance identifier can be determined from the customer local area network identifier. The header information and backbone service instance identifier can be concatenated with the customer frame component to form a frame. The frame can be provided to an egress port of the network device for transmission, where the egress port is determined from the header information.
