20090113068 | Content delivery system, cache server, and cache control server - In a cache control assuming plural user terminals accessing identical content, cache delete priority assignment is performed from a position where a user finished playback based on whether the user intends to view the content later. A cache control server is provided, and a cache delete inhibit span is determined based on a playback stop position or a normal speed playback time. A cache server deletes the cache based on the delete inhibit span received from the cache control server. Traffic of the core network due to re-cache can thus be reduced. | 04-30-2009 |
20100115565 | CONTENT AND CM DELIVERY SYSTEM AND CONTENT INFORMATION SERVER - In a content delivery system comprising a content information server, a content delivery server, and a terminal information server all located within a communications carrier network, the content information server obtains location information of a content requesting terminal from the location information server and generates a play list per terminal for inserting local CM content into main stream content depending on the terminal location. The content delivery server delivers the main stream content and the local CM content to the requesting terminal according to content identifiers specified in time sequential based on the play list per terminal by the content information server. | 05-06-2010 |
20100322072 | Packet Transfer System, Network Management Apparatus, and Edge Node - A packet transport system to which the present invention is applied includes an edge node accommodating an access network at an edge, and a core node of carrying out a processing of assorting a frame gathered from a plurality of the edge nodes, the edge node provides a label to the frame flowing in from the access network, and the packet transport system transmits the frame in reference to the label. The edge node includes a priority information providing portion of changing a piece of priority information provided to the frame flowing in from the access network in accordance with a congested state of the core node, and a priority previously set to a path specified by the label. | 12-23-2010 |
20120163384 | Packet Transport Node - A packet transport node that composes a transport network, the transport network transports networks that is composed with a communication protocol, the network transports networks is established logical paths used a routing protocol. The packet transport node forwards a user data packet and a routing protocol packet to an appropriate destination. The packet transport node learns correspondence between a logical path of a transport network and a MAC address based on a MAC header of a received packet and learns correspondence between a logical path of a transport network and a logical path used in other network by snooping a routing protocol packet. | 06-28-2012 |
20120294307 | Apparatus and Method for Identifier Management - An identifier management apparatus capable of setting identifier conversion information of a new user without affecting identifier conversion processings of other users, and an identifier management method. The identifier management apparatus converts an identifier given to communication data. Its memory stores multiple hash functions, output values of the hash functions corresponding to the respective plurality of hash functions, multiple entry tables that manage the identifier conversion information indicating a correspondence between the input identifier being an input value of the hash function and an output identifier obtained by converting the input identifier, and a management table for managing a setting status of the identifier conversion information in each entry table. When registering the new identifier conversion information in any entry table, its processor selects an entry table that should register new identifier conversion information depending on setting statuses of the identifier conversion information in the entry tables. | 11-22-2012 |
20130272116 | COMMUNICATION SYSTEM, COMMUNICATION METHOD AND NETWORK MANAGEMENT APPARATUS - In an example of the invention, network devices are classified into areas. Each of the areas includes edge nodes. A network management apparatus retains fault information including values each indicating whether or not a fault has occurred in each of the areas, retains detour path information including values indicating edge nodes, values indicating alternative areas to the areas and priorities assigned to the alternative areas, identifies, when determined that a fault has occurred in a first area based on the fault information, an alternative area to the first area based on the detour path information, determines, when determined that the fault has not occurred in the identified alternative area, the identified alternative area as a second area through which the active path passes, determines two edge nodes included in the second area, and detect network devices through which the active path passes between the two edge nodes. | 10-17-2013 |
20130329547 | COMMUNICATION DEVICE AND METHOD OF CONTROLLING THE SAME - Provided is a communication device including a plurality of physical ports, the communication device holding information for associating each of at least one logical port and at least two physical ports, the communication device being configured to: identify, when any one of the plurality of physical ports receives data including user data, one of the at least one logical port as an output destination of the data based on destination information included in the received data; select, based on the data, one of the at least two physical ports associated with the identified logical port as an destination of the data; generate coupling check data relating to one of the plurality of physical ports; transmit the coupling check data from the one of the plurality of physical ports; and transmit data including the user data from the physical port selected by a first processing unit as the output destination. | 12-12-2013 |

20110248788 | GLASS SUBSTRATE POLISHING METHOD, PACKAGE MANUFACTURING METHOD, PIEZOELECTRIC VIBRATOR, OSCILLATOR, ELECTRONIC DEVICE AND RADIO TIMEPIECE - A glass substrate polishing method having polishing processes for polishing a glass substrate surface while supplying a polishing agent. The glass substrate polishing method is characterized in that the polishing processes include a first polishing process in which the surface of the glass substrate is polished using a first polishing pad made from a polishing cloth and a second polishing process in which the surface of the glass substrate is polished using a second polishing pad made from urethane foam. | 10-13-2011 |
20110249533 | GLASS SUBSTRATE POLISHING METHOD, PACKAGE MANUFACTURING METHOD, PIEZOELECTRIC VIBRATOR, OSCILLATOR, ELECTRONIC DEVICE AND RADIO TIMEPIECE - A glass substrate polishing method for polishing a glass substrate using a polishing device is provided. The glass substrate polishing method is characterized in that the polishing device includes a surface plate that is rotationally driven around a first central axis, a plate that is rotatable around a second central axis eccentric from the first central axis and presses the glass substrate toward the surface plate, and a work holder that is formed on the plate and restricts movement of the glass substrate in a surface direction while holding the glass substrate in a state in which a central axis of the glass substrate is eccentric from the second central axis. The glass substrate is polished by rotating the surface plate while the glass substrate is rotatably held in the work holder in a state in which an abrasive is interposed between the glass substrate and the surface plate. | 10-13-2011 |
