  • Patent number: 10015098
    Abstract: Various embodiments of the invention provide for an unparalleled scalable and reliable load distribution design for use in a large class of network applications, including cloud computing in modern data center networks and similar services, which can benefit from the invention by taking advantage of commonly available network components and systems. In particular, various embodiments of the invention extend a logical load distributor model to include distributed clusters of loosely coupled components. Certain embodiments accomplish this by combining existing silicon-based network components and functionalities with the scalability and reliability provided by virtualized processes in order to improve critical load distribution and load balancing performance without requiring costly upgrades to infrastructure and without negative structural impact on the overall network. Some embodiments take advantage of hierarchical designs to further increase scalability.

  • Patent number: 9954758
    Abstract: A virtualized network function (VNF) provisioning system includes a plurality of computing device that are provided in a physical topology and that are coupled to a network. A management device is coupled to the computing device through the network. The management device receives VNF system information for a VNF system through the network. The VNF system includes a plurality of VNFs that are provided in a virtual topology. The management device then determines a plurality of physical groups from the physical topology that each identify at least one computing device. The management device then determines a plurality of virtual groups from the virtual topology based on a ratio of traffic that will leave each virtual group and a number of VNFs in each virtual group. The management device then provides the VNFs in a first virtual group on the at least one computing device in a first physical group.

  • Patent number: 9749934
    Abstract: An information handling system is provided herein. The information handling system includes a controlling bridge having a plurality of bridge ports and at least one port extender coupled to one of the bridge ports of the controlling bridge to form an extended bridge. The port extender has a plurality of extension ports. The information handling system further includes an access point coupled to the port extender such that a wireless association between the access point and one or more stations appears as a logical bridge port to the controlling bridge and to an access controller system. The access point has a wireless transceiver to communication with the one or more stations. Associated methods are provided herein for providing wireless network access to a local area network.
