Abstract: Transferring data in a network is disclosed. Transferring includes receiving a Provider Backbone Transport (PBT) frame, identifying a plurality of location specific identifiers in the PBT frame, mapping the PBT frame to a service based at least in part on the plurality of location specific identifiers, formatting the PBT frame according to the service to obtain a service frame, and transferring the service frame to a network associated with the service.

Abstract: One embodiment provides a system that facilitates bandwidth-profile enforcement. During operation, the system indicates a packet's compliance with a bandwidth profile based at least on available high-compliance tokens and medium-compliance tokens. The system further converts, within different classes of service (CoSs), an overflow high-compliance token to a medium-compliance token, in a top-down or bottom-up fashion with respect to different CoS priorities.

Abstract: One embodiment provides a system that facilitates bandwidth-profile enforcement. During operation, the system indicates a packet's compliance with a bandwidth profile based at least on available high-compliance tokens and medium-compliance tokens. The system further accounts for overflow tokens from a respective class of service (CoS) and distribute an overflow token to another CoS priority level based on the overflow token's CoS information.

Abstract: Frame contained destination information may be used by a switch to identify an appropriate output port for a given frame without performing a table access operation. This reduces the processing requirements of the switch to enable the switch to handle frames more efficiently. The frame contained destination information may be contained in the frame's local destination MAC addresses (DA) such that a portion of the DA directly indicates, for each switch that handles the frame, an output port for that switch. Different portions of the DA may be used by different switches, depending on where they are in the network hierarchy. Large switches may also use sub-fields within their allocated portion in the DA to identify internal switching components. A location resolution server may be provided to store and distribute IP and MAC addresses and respond to local ARP requests on the local domain.

Abstract: An E-Tree is disclosed which includes a root node associated with a Metro Ethernet network. The E-Tree includes a first Virtual Bridge (VB), associated with the root node, which is configured to process Ethernet traffic, and a second node associated with the Metro Ethernet network. The E-Tree includes a second VB, associated with the second node, configured to process Ethernet traffic and having a first connection between the first VB and the second VB. The second VB is configured to be able to send Ethernet traffic to the first VB via the first connection, if appropriate. In the event there is a second connection between the second VB and a third VB and the second connection has been assigned a down direction from the point of view of the second VB, the second VB is not permitted to send traffic received from the second connection to another connection which from the point of view of the second VB has been assigned a down direction.
