20130060966 | METHOD AND APPARATUS FOR FORMING A TIERED WIRELESS LOCAL AREA NETWORK (WLAN) SERVER TOPOLOGY - A method, apparatus and computer program product for forming a tiered Wireless Local Area Network (WLAN) server topology is presented. A Wireless Local Area Network (WLAN) having a plurality of Mobile Virtual Local Area Network (MVLAN) servers is broken into a plurality of zones, each zone including at least one MVLAN server. An Identifier (ID) is assigned to each zone. A MVLAN server in each zone is designated as a MVLAN gateway server, wherein MVLAN servers within a zone communicate with each other within the zone, wherein the MVLAN servers within a zone communicate directly with the MVLAN gateway sever within the zone, wherein MVLAN gateway servers communicate directly with each other, and wherein a MVLAN server within a first zone communicates with a MVLAN server in a second zone by way of the MVLAN gateway sever of the first zone and the MVLAN gateway server of the second zone. | 03-07-2013 |
20130124750 | NETWORK VIRTUALIZATION WITHOUT GATEWAY FUNCTION - A local network, such as a data center, includes a plurality of servers each of which are linked to a network switch. Some of the plurality of servers are network virtualization capable and some are not. The network virtualization capable servers include functionality that encapsulates a data frame, generated by one network virtualization servers that is to be sent to another network virtualization capable server, with a network virtualization identity. In the event that a network virtualization server generates a data frame for transmission to a server that is not capable of network virtualization, the network virtualization capable server does not encapsulate the data frame with the network virtualization identity. | 05-16-2013 |
20130322441 | SCALING UP/OUT THE NUMBER OF BROADCAST DOMAINS IN NETWORK VIRTUALIZATION ENVIRONMENTS - A method for handling multicast traffic is presented. A method of handling multicast traffic according to some embodiments of the present invention includes forming IP multicast (IPMC) groups of hypervisors based on broadcast domains; and directing multicast traffic from a broadcast domain on a source hypervisor to hypervisors that are members of the IPMC group. | 12-05-2013 |
20140192804 | SYSTEMS AND METHODS FOR PROVIDING MULTICAST ROUTING IN AN OVERLAY NETWORK - 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. | 07-10-2014 |
20140254406 | SYSTEM AND METHOD FOR VIRTUAL PRIVATE APPLICATION NETWORKS - A system and method for virtual private application networks includes receiving a first packet associated with a first network flow at a network device, determining one or more first characteristics of the first network flow based on information associated with the first packet, determining one or more second characteristics of a first virtual private application network (VPAN) based on information associated with the one or more first characteristics, assigning the first network flow to the first VPAN, selecting one or more first network switching devices to be associated with the first VPAN, and transmitting one or more first flow control messages to the selected one or more first network switching devices. The one or more first flow control messages provide forwarding instructions for network traffic associated with the first network flow to the selected one or more first network switching devices. | 09-11-2014 |
20140254605 | SYSTEM AND METHOD FOR STORING FLOW ENTRIES IN HARDWARE TABLES - A system and method for storing flow entries in hardware tables includes one or more controllers, memory, a first flow table for storing first flow entries, and a second flow table for storing second flow entries that override the first flow entries. The first flow table implements a fixed priority and the second flow table a flexible priority. The one or more controllers is configured to add a third flow entry with a first priority to the first table when the first priority is consistent with priorities of all overlapping first flow entries, move selected overlapping first flow entries to the second table and add the third flow entry to the first table when moving the selected first flow entries removes any priority inconsistencies in the first table when the third flow entry is added to the first table, and otherwise add the third flow entry to the second table. | 09-11-2014 |
20140269252 | SYSTEMS AND METHODS FOR MANAGING SWITCHING DEVICES IN AN INFORMATION HANDLING SYSTEM - Systems and methods are provided that allow for the management of switching devices in an information handling system without having to access the switching device. An information handling system as provided herein includes at least one switching device and a controlling device in communication with the at least one switching device. The controlling device includes a network interface component configured to receive a request from the at least one switching device, and one or more processors. The one or more processors are configured to provide configuration settings and an operating system to the at least one switching device in response to the received request, record network traffic of the at least one switching device, provide the recorded traffic to an analytics engine, and debug the at least one switching device based on information received from the analytics engine. | 09-18-2014 |
20140269295 | SYSTEM AND METHOD FOR MANAGEMENT OF VIRTUAL SUB-NETWORKS - A system and method for management of virtual sub-networks includes a network controller including a control unit and one or more ports coupled to the control unit. The network controller is configured to receive a first admit request from a network switching device on a first virtual sub-network, form a first admit response based on information associated with the first admit request, transmit the first admit response to the network switching device on the first virtual sub-network, form one or more first flow control messages including configuration information for coupling the network controller and the network switching device using a second virtual sub-network, transmit the one or more first flow control messages, transmit a first migrate message to the network switching device, and exchange management traffic with the network switching device using the second virtual sub-network. | 09-18-2014 |
