Abstract: A system and method for forwarding network traffic includes receiving a first flow of network traffic at an ingress port on a switch, collecting flow control metrics for a plurality of egress ports assigned to a link aggregation group of the switch, selecting a first egress port from the plurality of egress ports using a hashing strategy based on at least information associated with the flow control metrics, assigning the first flow to the first egress port, directing the first flow to the first egress port, and transmitting network traffic associated with the first flow using the first egress port.

Abstract: An information handling system is provided. The information handling system includes a first hypervisor running on a first host and a second hypervisor running on a second host. The first hypervisor managing a first virtual switch, and the second hypervisor managing a second virtual switch. The information handling system also includes a plurality of virtual machines (VMs), including a first VM, which is part of a first tenant, running on the first host, and a second VM, part of a second tenant, running on the second host. The first virtual switch has a mapping in memory that maps a customer-specific multicast IP address, used by the plurality of VMs to indicate a multicast group that includes VMs on the first and second tenants, to a global multicast IP address used by the first and second hosts.

Abstract: An information handling system is provided. The information handling system includes a plurality of forwarding processors, the plurality of forwarding processors each including a memory having a forwarding host table and a forwarding route table. The information handling system also includes at least one switching device coupled to the plurality of forwarding processors, the at least one switching device including a memory having a destination module and port table, a switching device host table and a switching device route table, wherein the at least one switching device is configured to perform an extended lookup in at least one of the switching device host table and switching device route table based on values included in a fabric header of information routed to the switching device to determine a destination of the information. A method for extending lookup tables is also provided that adds lookup tables in a switching device.

Abstract: A packet switch receives a management packet sent for discovery on a data flow's path through a network. The switch creates a test packet (310T) which looks like a packet belonging to the data flow of interest. The test packet is processed by the switch like the data flow of interest except that the test packet is not necessarily transmitted. The processing results may include the egress ports for the test packet, and if the ports are part of a LAG or ECMP group, the results provide the group and the group members associated with the egress ports. Firewall actions and other information can be included. The switch may forward the results to the originator of the management packet. The switch may insert the results into the management packet and forward the management packet on the ports determined as egress ports for the test packet. Other features are also provided.

Abstract: An information handling system is provided. The information handling system includes a plurality of routing bridges coupled to at least one node. The node may be multihomed and logically coupled to the rest of the information handling system through a virtual routing bridge. Methods and systems are provided to allow multicast packets originating behind the virtual routing bridge to be properly handled to comply with reverse path forwarding. This may be accomplished by creating and selectively using a plurality of routing trees that include the paths between the virtual routing bridge and neighboring physical routing bridges.

Abstract: A network switch is comprised of a control processor and one or more line cards. The control processor includes functionality to register interest with a hypervisor, operating in conjunction with a network host connected to the switch, in data object attributes maintained on the network host by the hypervisor. The hypervisor associated with the network host sends changes in the host attributes to the switch which the switch maintains in a listing of attributes. The switch traps and copies particular packets to the switch control processor where a provisioning function operates on the attribute information in the list with source information included in the packet header in order to configure a forwarding table on the line card.

Abstract: A provided information handling system includes a plurality of aggregation devices configured to distribute information in a virtual link trunk and a plurality of nodes coupled to the aggregation devices. When an aggregation device receives a reboot command, that aggregation device is configured to transmit a first message to the nodes indicating that the aggregation device is rebooting, and receive a first acknowledgement message from the nodes indicating that they will not send any information to the rebooting aggregation device. The aggregation device is then configured to reboot, receive a second message from the nodes indicating the nodes are ready to receive information from the rebooted aggregation device, transmit a second acknowledgement message to the nodes indicating that the rebooted aggregation device has rebooted and is capable of receiving information, and receive information from one of the nodes for transmission to another node.

Abstract: A computing environment is provided with the ability to at least contribute to the persistent naming of the divided sub-paths, including their edges and vertices, of a continuous path of an intermittent fillet weld bead, including the determination of an invariant weld bead generation direction.
