    摘要： In one embodiment, an access component of a local network edge device receives traffic, and generates a frame for the traffic that includes a remote context label that identifies an access component of the remote network edge device to which the traffic is to be forwarded upon arrival at the remote network edge device, and a virtual circuit label corresponding to a particular virtual service of the traffic. The local network edge device forwards the frame towards the remote network edge device. In another embodiment, the frame may be received at a core component of the remote network edge device, an in response to the remote context label identifying an access component of the remote network edge device, forwarded to the access component, which determines the particular virtual service, and forwards the traffic from the frame out the access component towards an endpoint for the traffic.

    摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with the coordinated updating of forwarding information bases (FIBs) in a multistage packet switching device, which performs at least lookup operations on multiple different FIBs in determining how to forward a packet. One embodiment uses lookup operations on two different FIBs, with these being an ingress FIB on an ingress line card and an egress FIB on an egress line card. In response to a change in the forwarding information for a stream of packets, the egress FIBs are first updated to include both the old and new forwarding information. After all egress FIBs have been updated, the ingress FIBs are updated to use the new forwarding information. This update procedure is designed to eliminate loss or duplication of packets induced during the updating of these FIBs to use the new forwarding information.

    摘要： A packet switching device maintains mappings of bridge identification values to line cards for each of multiple virtual bridges. When a packet is received that includes a bridge identification value, corresponding line card(s) are identified, with each being forwarded the packet. Each of these identified line cards, in response to receipt of the packet from the line card, determines whether to forward or drop the packet based on its maintained bridge table. In this manner, the original receiving line card does not need to maintain forwarding information based on destination addresses of received packets (e.g., does not need to maintain a bridge table for each virtual bridge), but rather forwards a packet to other line cards associated with the virtual bridge corresponding to the bridge identification value received in a packet.
