Abstract: A network management apparatus and method for determining the topology of a network 1 is described. The present invention uses data relating to discovered devices on the network 1, typically network management address table data, to build a network tree. Due to the presence of unsupported or unmanaged connecting network devices, some branches of the resulting tree may not be resolved. In order to address this, for each unresolved branch of the network tree, the present invention attempts to determine the type of each of the discovered network devices on the branch, and if the type of every discovered network device on the branch is determined to be an endstation type, the present invention determines that an undiscovered connecting device is present on the branch.

Abstract: An information processing method and apparatus for enabling more prompt sign-up. A network management server at step S62 received am equipment serial number from an information processing apparatus and, at step s63, references a database to retrieve a received equipment serial number. If the equipment serial number has not been found, the program moves to step S16 where a command for initiating manual setting is sent to an information processing apparatus. If the equipment serial number has been found, the program moves to step S81 to verify whether or not the admittance made or admittance not as yet made, recorded in the database in association with the equipment serial number received is admittance made. If the verified result indicates admittance not as yet made, the program moves to step S82 where the network management server sends an automatic setting initiating command to the information processing apparatus.

Abstract: An online machine data collection and archiving process generates a machine data profile of a customer computer accessing a transaction form of a merchant web site and links the machine data profile and a transaction record with customer identifying information using a unique transaction identification string. The process preferably captures parameters typically communicated as a part of web accesses, such as an IP address, an HTTP header, and cookie information. The process additionally causes the customer computer to process self-identification routines by processing coding within the merchant transaction form, the self-identification routines yielding further profile parameters. The process further includes a routine for bypassing an intervening proxy to the merchant web site to reveal the true IP address of the customer computer.

Abstract: A system for preventing timeout of a client interface accessing a main Java Servlet executing in a first thread which monitors an application executing in a second thread. A task status object is accessed by the application to post its completion state and by the client interface responsive to a state refresh request to post a state refresh response including the completion state to the client. The state refresh response selectively includes a refresh attribute instructing the client to periodically post the state refresh request. Upon the application going to completion or error state, subsequent state refresh responses do not include the refresh attribute.

Abstract: A server receives an acquisition request for visual content, such as desired text or image content, from a client terminal via a communication network, and retrieves, from a database, data of the visual content requested by the client terminal. Then, by analyzing the visual content, by referring to an appropriate table or otherwise, the server determines music content or effect tone content to be imparted to the requested visual content in associated relation to specific substance of the requested visual content. Then, the server retrieves data of the determined music content or effect tone content from a database, and transmits the data of the visual content, along with the data of the music content or effect tone content, to the client terminal. On the basis of the data transmitted by the server, the client terminal can not only visually display the requested visual content but also audibly reproduce the music content or effect tone content.

Abstract: One embodiment of the present invention provides a system for distributing files across a network. During operation, the system receives a request at a server to download a file to a client. If the server is not currently downloading the file, the system commences a download stream for the file on a multicast port. If the server is currently downloading the file, the system remembers a marked location on the file, wherein the marked location relates to a current packet number of the download stream on the multicast port. The system then continues downloading the file until the end of the file, thereby allowing the client to receive the remainder of the file. Next, the system downloads the file from the beginning of the file to the marked location, thereby allowing the client to receive previously transmitted portions of the file.

Abstract: The present invention provides a technique for efficiently looking up address-routing information in an intermediate network node, such as a router. To that end, the node locates routing information stored in its memory using one or more “lookup” tables (LUT) which can be searched using a small, bounded number of dependent lookups, thereby reducing the number of dependent lookups conventionally performed. The LUTs are arranged so each table provides routing information for network addresses whose subnet mask lengths are within a different range (“stride”) of mask lengths. According to the technique, the node locates a network address's routing information by searching the LUTs, in order of decreasing prefix lengths, until the routing information is found. Preferably, several tables are searched in parallel. A match in a LUT may further point to a small MTRIE that enables the final bits of a prefix to be matched. That final MTRIE is searched using a relatively small, bounded number of dependent lookups.

Abstract: Asynchronous messages are used to prefetch and/or relinquish tokens used in providing locking of shared resources. A message is sent to prefetch one or more tokens, and prior to receiving a reply for the message, another message (e.g., an acquire) is sent for at least one of those tokens. Similarly, a message is sent indicating a voluntary relinquish of one or more tokens and without having acknowledgment that the relinquish request was processed, a further message (e.g., an acquire) is sent for at least one of the tokens. Multiple tokens may be acquired and/or relinquished in a single message to the token server. This reduces message delays and overall message traffic.

Abstract: A self-configuring server system is disclosed. In this system, a plurality of nodes are linked together in a primary loop. Each node includes an external communication interface coupled to the loop, a command module for controlling the node and an internal interface. The internal interface, for each node, is in turn coupled to an internal loop associated with that node, the internal loop defining operation of that node. Messages and data circulate around the primary loop until reaching an appropriate node, where the message or data is acted upon. In some instances the messages or data is client-related, and in other instances the messages or data provide for dynamic reconfiguration of the system. In yet other instances, the messages or data is transmitted from one or more nodes in order to provide operational data about the node/nodes to a plurality of system controllers.
