    Abstract: Techniques for configuring/learning the link aggregation groups (LAGs) of a port extender (PE) at the time the PE joins an extended bridge are provided. According to one embodiment, a first network device in a system of network devices (e.g., an extended bridge) can receive a join message from a second network device in the system, where the join message includes a LAG configuration for one or more LAGs programmed on the second network device. The first network device can further determine whether a provisional LAG configuration for the one or more LAGs of the second network device exists on the first network device. If a provisional LAG configuration does not exist on the first network device, the first network device can learn the LAG configuration included in the join message and can integrate the second network device into the system based on the learned LAG configuration.

    Abstract: Systems, methods, apparatus and computer-readable medium are described for improving efficiency and robustness for processing network packets at a network device, such as a customer premises equipment (CPE). The network device may include a plurality of physical network interfaces for receiving and transmitting network packets, and one or more processing entities. The one or more processing entities may provide a first router for providing routing functionality, wherein the first router is not virtualized, enable a virtual machine to execute a second router for providing routing functionality and forward a network packet using the first router or the second router from the device. The one or more processors may be configured to execute instructions associated with the first router from user space.

    Abstract: One embodiment of the present invention provides a switch 101, 102, 103, 104, 105 in a network 100. The switch includes a virtual network module and a forwarding module. The virtual network module includes a global virtual local area network (VLAN) tag in a packet. The global VLAN tag is mapped to an edge VLAN tag in the packet and is associated with a datacenter domain 172, 174, wherein a VLAN 152, 154 associated with a packet received from an edge port of the switch can be referred to as an edge VLAN and a corresponding identifier or tag can be referred to as an edge VLAN tag. The datacenter domain indicates a set of ports associated with a datacenter 120 130. The forwarding module identifies an egress edge port for the packet based on the global VLAN tag. Preferably, the global VLAN tag is mapped to an internal virtual identifier (IVID), which is internal and local to the switch. Moreover, the forwarding module preferably is further adapted to identify the egress edge port based on a mapping between the egress port and the internal virtual identifier. The global VLAN tag may be mapped to a media access control (MAC) address in the packet. In an embodiment, the switch is member of a TRILL network 100 (Transparent Interconnection of Lots of Links) and the global VLAN tag can be included in an encapsulation header such as a TRILL header.

    Abstract: One embodiment of the present invention provides a switch. The switch is configurable to be a member of a first fabric switch. The switch includes a link aggregation module. During operation, the link aggregation module marks an ingress-switch field of a frame with a virtual switch identifier. This virtual switch identifier is associated with the switch and a second switch, which is a member of a second fabric switch, and is from a range of identifier associated with the first fabric switch and the second fabric switch. Each of the first fabric switch and the second fabric switch is operable to accommodate a plurality of switches and operate as a single switch.
