20150365268 | COMMUNICATION SYSTEM AND METHOD OF CONTROLLING THE SAME - A relay server generates a search condition in accordance with a connection request from the first terminal, and requests so that a management server searches for a state of the first terminal; when device information of the first terminal which is transmitted from the management server in response to the request is obtained, generates relay information and transmits the relay information to the first terminal; and controls communication between the first terminal and the second terminal in accordance with the relay information. The management server searches for state information of the first terminal in accordance with the requested search condition, and communicates the state information to the relay server as the device information; and in accordance with receiving the relay information from the first terminal, transmits the relay information to the second terminal. | 2015-12-17 |
20150365269 | USAGE OF MAPPING JUMPER PINS OR DIP SWITCH SETTING TO DEFINE NODE'S IP ADDRESS TO IDENTIFY NODE'S LOCATION - A method for identifying the location of a server node in a cloud computing room includes determining IO level definition of IO ports according to an IP-Mapping table containing a physical location, an IP address, and an IO level definition for each server node, powering on all the server nodes, retrieving the IO level definition from high/low states of the IO ports, defining the IP address according to the IO level definition retrieved and the IP-Mapping table, detecting hardware or software errors and sending event alert messages when errors are detected in a particular server node, reinstalling or resetting the particular server node when diagnosing, and locating the server node from the IP address of the particular server node and the IP-Mapping table. | 2015-12-17 |
20150365270 | ACTIVE IP FORWARDING IN AN EVENT DRIVEN VIRTUAL LINK AGGREGATION (VLAG) SYSTEM - In one embodiment, a networking switch includes an interswitch link (ISL) interface configured to communicate with a second networking switch via an ISL and a networking port configured to connect to an access switch in Layer-2 (L2) via a virtual link aggregation (vLAG) with the second networking switch. The networking switch includes a virtual router redundancy protocol (VRRP) module configured to perform active interact protocol (IP) forwarding. Moreover, the VRRP module is configured to indicate a status of the networking switch to the second networking switch via the ISL. The status is one of: initialization when the networking switch is not currently active (INIT), back-up status when the networking switch is acting as a back-up switch (BACK-UP), or master status when the networking switch is acting as a master switch (MASTER). In addition, the networking switch is positioned at a boundary between L2 and Layer-3 (L3). | 2015-12-17 |
20150365271 | OPTIMIZATION TO EXPAND IS-IS LEAF NODES DURING LFA COMPUTATION - A method and system implemented by a network device, where the network device is in a network having a plurality of nodes. The method computes a loop free alternative (LFA) next hop as a backup for a primary path next hop for intermediate system-intermediate system (IS-IS). The method improves LFA computation efficiency by minimizing expansion of prefixes. The method includes expanding all prefixes of the next LFA shortest path first (SPF) destination node and inheriting a next candidate next hop as a current LFA next hop where the next candidate next hop provides link or node protection and better protection than the current LFA next hop. | 2015-12-17 |
20150365272 | Control System, Control Method of a Control System, and Control Device - In a control system in which a terminal with a browser and a control device communicate through a network, the system and control device are made compatible with a configuration in which the devices communicate through a network. | 2015-12-17 |
