To that end, a first ring topology network configured in a ring shape has three or more expandable nodes (each have three or more Ethernet ports), and is connected to other networks through Ethernet ports that are not used for the formation of the first ring topology network among Ethernet ports of the expandable node. Thus, it is possible to add equipment without changing a ring topology network previously built and it is possible to integrate and manage networks of various shapes into a single network. | 05-08-2014 |
20160036602 | Internet Protocol Addressing of Devices Employing the Network Ring Topology - Aspects of the present invention provide a ring supervisor operating as a server for maintaining and allocating addresses for devices in a ring topology. The ring supervisor may obtain an ordered list of devices in the ring by sending a data collection frame that passes through each device around the ring with each device appending its preconfigured address information. The ring supervisor may then operate to apply the addressing provided by each device, or alternatively, allocate different addresses to each device from a separate pool. As a result, control program software for ring devices can he developed using a general pool of addresses without requiring specific knowledge of actual addresses. Also, if a device requires replacement, the device may be replaced without requiring modification to the control program to provide the address for the replacement device. | 02-04-2016 |

20120195321 | Method and Apparatus for Low-Latency Interconnection Networks Using Hierarchical Rings - An apparatus comprising a chip comprising a global ring network comprising a plurality of global routers configured in a unidirectional ring network, and a plurality of local ring networks directly connected to the global ring network. A method comprising transmitting a first flit from a first router to a second router, wherein a first ring network comprises the first and second routers, and transmitting a second flit from the first router to a third router, wherein a second ring network comprises the first and third routers, wherein the first and second ring networks are in a hierarchical relationship with each other, and wherein a chip comprises the first and second ring networks. | 08-02-2012 |
20120224589 | RELAY STATION AND RELAY METHOD - A relay station for relaying data between first and second ring networks, each of the first and the second ring networks including a plurality of stations includes a first transmission and receiving circuit transmitting and receiving data to and from the first ring network; a second transmission and receiving circuit transmitting and receiving the data to and from the second ring network; and a switch that, when a destination of the data received by the first transmission and receiving circuit is one of the stations included in the second ring network, inputs the data to the second transmission and receiving circuit, and, when a destination of the data received by the second transmission and receiving circuit is another of the stations included in the first ring network, inputs the data to the first transmission and receiving circuit. | 09-06-2012 |
20130016733 | METHODS AND APPARATUS FOR FIBRE CHANNEL INTERCONNECTION OF PRIVATE LOOP DEVICES - Methods and apparatus for communicating Fibre Channel frames between a private loop device and an Ethernet link through a Fibre Channel private loop device interconnect system. In the preferred embodiments, the Fibre Channel private loop device interconnect system is a fabric or an intelligent bridging hub. In one aspect of this invention, a Fibre Channel private loop device is storage device which contains JBODsd or RAIDs. Preferably, the interconnect system includes a routing filter to filter incoming Arbitrated Loop physical addresses (ALPAs) to determine which Fibre Channel frames must attempt to be routed through the fabric. Numerous topologies of interconnect systems may be achieved. | 01-17-2013 |
