Abstract: Virtual routers within a single physical router share a centralized data plane containing a centralized switch fabric and a plurality of physical network interfaces, each assigned to only one virtual router. Using a logical cut-through device between a pair of virtual routers designated respectively client and server, packet forwarding information from the server is imported into the client, which creates, allocates, and maintains a data structure for the imported information, which then resides on the client interfaces. This imported forwarding information is then integrated into a single forwarding table that is used to recognize an incoming packet at the client and forward it appropriately out through a server interface with a single packet forwarding decision in a single transit through the switch fabric. Within a physical router, a client virtual router can communicate with multiple servers and can concurrently function as a server to multiple clients.

Abstract: A contents filtering method is capable of allowing use of network resources to be filtered, within a predetermined allowable range. The contents filtering method monitors communications of contents on the network and determining whether the contents are regulated contents satisfying predefined regulatory requirements or not (step S1), and then counts the number of times that the regulated contents are communicated (step S2). The contents filtering method converts a loss caused by communicating the regulated contents into an incurred cost based on the counted number of times that the regulated contents are communicated (step S3), and, if the incurred cost is in excess of a preset permitted cost, inhibits subsequent communications of the regulated contents (step S4).

Abstract: A user operates a digital camera so as to attach a photographed image to an e-mail describing a user ID and space ID, and transmit the e-mail to a mail server. The mail server reads out the user ID, space ID, and attached image data from the received e-mail. After setting a frame ID for a frame to exhibit the image data in a shared virtual space, the mail server transmits the image data, space ID, and frame ID to an AO server. The AO server stores the received data and also transmits the data to a CP server. The CP server transmits the received data to multiple client computers. The client computers display the received image at a predetermined location in the shared virtual space, specified by the frame ID. This allows the user to easily upload information.

Abstract: A continuous update method includes reading out data from a first data store via a data switch to satisfy client requests for data. A second data store is updated via the data switch to contain new updated information. When it is desired to satisfy client requests with the new data, the second data store is copied to a third data store and subsequent client requests are satisfied from the third data store. Further updates are made to the second data store. The process is repeated, but the roles of the third and first data stores are reversed. In another embodiment of the invention, subsequent client requests are satisfied from the second data store and further updates are made to the first data store.

Abstract: A cluster management unit provided in each of two servers carries out a state-transition in accordance with a state transition diagram both in cases where a fault occurs in at least one of the two servers and where the server is restored from the fault. A state writing processor provided in a server priority process unit of the each server stores, into a disk drive, a server priority determined based on a server state indicated by state change information. When faults occur in the two servers and at least one of the two servers is thereafter restored from the fault, a comparing processor in the server priority process unit of the one server determines whether or not the priority of the one server is higher than the priority of the other server, based on at least the priority of the one server. The cluster management unit of the one server carries out a corresponding state-transition based on this determination result and state transition diagram.

Abstract: The present invention relates to a method comprising improvements in transferring large data amounts e.g., large files associated with ‘new media’ like audio and video data which are streamed through the network. The present invention comprises basically to decouple the transfer and the rendering of data in a way that combines the strength, i.e., the advantages of the streaming paradigm with the flexibility and usability advantages of the store&forward paradigm. This is basically achieved by separating the application logic from the transport logic. The transfer/transport logic is covered by a novel transfer protocol whereas the player application logic can issue standard file access statements like fread, fseek in order to access and render the streamed data.
