摘要： Forwarding Ethernet packets is disclosed, including: receiving an incoming packet; determining a value based at least in part on performing a hash operation on at least a portion of a destination Internet Protocol (IP) address included in the incoming packet; comparing the value against a pre-established look-up table to determine whether a corresponding index value is found, wherein the pre-established look-up table stores index values and corresponding data sets to respective ones of the index values; determining a destination media access control (MAC) address associated with the incoming packet based at least in part on whether the corresponding index value is found in the pre-established look-up table; and forwarding the incoming packet to a virtual machine associated with the determined destination MAC address.

摘要： Multiple virtual MAC addresses may be added to WGA devices that may have different traffic streams to another device that requires different services, thus creating distinct MAC and device level implications. Beamforming training can be done at the device level for all virtual MAC addresses. Wakeup, doze, and ATIM power save can be done at the device level depending on the frames received. Authentication, deauthentication, association, and deassociation can be done variously at both levels. Further MSDUs can be aggregated for the multiple MAC addresses.

摘要： A managed network provides unique network addresses that are assigned to nodes such that no two nodes will have the same address in the managed network and such that each node will always have the same network address regardless of changing its location or changing the network to which it is joined. The nodes, communicating together, comprise a mesh network. Remote management and control of the nodes is possible from the host server, which is located outside of the mesh network, even if a node is located behind a firewall or network address translator (NAT), because server management messages are encapsulated within headers so that a persistent connection between the node and the external host server is maintained once the node sends a message to the host.

摘要： This is directed to providing Fiber Channel over Ethernet communication. For example a Fiber Channel over Ethernet (FCoE) enabled device (such as a computer) may include a Fiber Channel over Ethernet Adapter (FCoEA). The FCoEA may include an HBA module. The HBA module may be configured to communicate over the Fiber Channel protocol. The FCoE enabled device may process and encapsulate the HBA module's communication in order to send them over an Ethernet network instead. The FCoE enabled device may process communications directed to various Fiber Channel fabric services by utilizing existing Ethernet services, such as an iSNS server. Thus, the FCoE enabled device can emulate a Fiber Channel network for the HBA module using the Ethernet network and one or more Existing Ethernet services/servers.

摘要： A method for forwarding data in a layer-2 network is provided. A first node receives a first data packet including a customer destination MAC address and customer data; generates a second data packet including a source virtual MAC address, a destination virtual MAC address and at least part of the first data packet. The at least part of the first data packet includes the customer destination MAC address and the customer data. The source virtual MAC address is a virtual MAC address assigned to the first node, and the destination virtual MAC address corresponds to the customer destination MAC address. The virtual MAC address assigned to the first node includes a first virtual MAC address segment with a first mask, which indicates a virtual MAC address space including virtual MAC addresses of child nodes of the first node. Then the first node forwards the second data packet.

摘要： In general, techniques are described for synchronizing gateway layer two (L2) addresses of routers that cooperate to provide interconnectivity to multiple, separate L2 networks. In one example, a router includes a VPLS module that establishes a VPLS instance to provide L2 connectivity between a local L2 network for the router and a remote L2 network for the router, wherein the router is addressable by a gateway L2 address. A synchronization module receives a gateway L2 address synchronization message that includes an additional gateway L2 address for an additional router. An integrated routing and bridging (IRB) interface of the router receives a L2 PDU from the local L2 network on an attachment circuit for the VPLS instance attached to the interface card, and a forwarding unit routes a layer three (L3) packet carried by the PDU when the PDU has an L2 destination address that matches the additional gateway L2 address.
