20090063556 | ROOT NODE FOR CARRYING OUT FILE LEVEL VIRTUALIZATION AND MIGRATION - An object ID comprises share information denoting a share unit, which is a logical export unit, and which includes one or more objects. Migration determination information denoting whether or not migration has been completed for each share unit is provided. A root node maintains the object ID in the migration destination of a migrated file, and updates migration determination information to information denoting that the share unit comprising this file is a migrated share unit. The root node, upon receiving request data having the object ID, determines, by referencing the above-mentioned migration determination information, whether or not the share unit denoted by the share information inside this object ID is a migrated share unit, and if this unit is a migrated share unit and if the file identified from this object ID is a migrated file, transfers the request data having the migration-destination object ID corresponding to this file to the migration-destination node. | 03-05-2009 |

20110004623 | WEB PAGE RELAY APPARATUS - To inform a terminal whether linked URLs contained in a browsed Web page are subject to browsing restriction, without placing a high load on a URL information database, a relay apparatus acquires a Web page from a Web server in accordance with a request from a terminal, queries a URL database as to a linked URL contained in the Web page, creates link information containing a restriction level to which a linked Web page belongs and the in-page location of a link display, determines a link subject to browsing restriction based on the link information and a predetermined restriction level of the requesting terminal, changes the link display, and sends the Web page with the changed link display to the terminal. Further, the relay apparatus caches the link information. If link information about a Web page acquired in accordance with a request from the terminal exists in a cache, the relay apparatus does not query URL information but uses the link information. | 01-06-2011 |

20090172318 | Memory control device - A memory control device that can improve the speed of a memory interface. A packet disassembly section disassembles packet data into segments and detects packet quality information. A memory management section has an address management table and manages a state in which the packet data is stored according to the packet quality information. A segment/request information disassembler disassembles the segments into data by an access unit by which memories can be written/read, and generates write requests and read requests according to the access unit. A memory access controller avoids a bank access to which is prohibited because of a bank constraint, extracts a write request or a read request corresponding to an accessible bank from the write requests or the read requests generated, and gains write/read access to the memories. | 07-02-2009 |
