Abstract: In a network management system performing a fault management process in a hierarchical network, an upper layer fault manager performs a fault management of an upper layer of a hierarchical network, a lower layer fault manager performs a fault management of a lower layer of the network, an inter-layer node connecting information storage portion manages connecting information between packet switching nodes composing the upper layer and link offering nodes composing the lower layer, and an inter-layer fault notifying portion notifies the upper layer fault manager, upon receiving a notification of a link fault which has occurred on a link between the link offering nodes from the lower layer fault manager, that the packet switching nodes affected by the fault are faulted, based on the connecting information.

Abstract: A group of network devices, such as Ethernet switches, are logically configured as a single cluster, with one commander device and one or more expansion devices. Each device in the cluster contains an embedded HTML server that facilitates configuration and management of the network device via a management station running a Web browser. Each device in the cluster is identified by a unique Universal Resource Locator (“URL”). However, only the cluster commander is required to have an IP address. The cluster commander redirects and translates configuration and management requests from the Web browser on the management station so that requests are processed by the appropriate device in the cluster. The exchange of information between the Web browser on the management station and the devices in a cluster is accomplished via redirection of HTTP GET and POST methods. This provides a consistent, device-independent interface between the device and the Web browser on the management station.

Abstract: A secure agent system for communicating with a secure remote access system is disclosed. The agent system is suitable for execution on a base device which is configured to be coupled to the internet. The agent system initiates data communication with the remote access system by sending requests and receiving replies from the remote access system. The replies may include requests to retrieve, store, update, and/or delete data associated with the base device, which the agent system carries out. The agent system further provides reply data to such requests to the remote access system.

Abstract: An information processing apparatus includes a channel selection task. The channel selection task controls an application program interface (API) to load a detecting microcode into a transport stream processor. The transport stream processor detects a transport stream based on the microcode, and outputs a signal representing detection of the transport stream to an interruption handler. The interruption handler outputs a semaphore signal to the channel selection task. The channel selection task controls the API to output an audiovisual microcode to the transport stream processor. The transport stream processor acquires program-specification information based on the microcode. The transport stream processor performs direct memory access transfer of the information to a memory 28, and outputs an interruption signal representing completion of the transfer to a software driver. The interruption handler outputs a semaphore signal representing completion of the transfer to the channel selection task.

Abstract: A network address for an object device is corrected. A recorded network address and a recorded unique enduring identification for the object device are read from a record. The recorded network address is queried for a returned unique enduring identification. The recorded network address is queried by performing an SNMP Get call to the recorded network address or addressing a unique enduring identification query to the recorded network address and receiving the response to the query. The returned unique enduring identification is compared with the recorded unique enduring identification. Responsive to a mismatch between the returned unique enduring identification and the recorded unique enduring identification, a current network address for the object device is resolved and the recorded network address is replaced with the current network address.

Abstract: A system and method are disclosed for a host platform interface (HPI), which defines a common set of functions implementing the native methods of Component Peer classes within the Java AWT. This allows the diverse native method implementations currently used in different versions of the AWT to be combined into a single body of source code, greatly improving code maintainability. Since the same source code defines a Component Peer class for each supported platform, changes or bug fixes need only be made in one body of code.

Abstract: A method and system for preventing a timeout from reaching a network host when bringing up a down link that is slow to waken. The method generally comprises receiving a request to access an information.

Abstract: A method for initializing a new node in a network. The network has multiple nodes arranged in a virtual tree format. The new node is a node of the tree, and each node of the tree has a set of attributes and a set of rolled up attributes to identify each node. A query is automatically sent to the nodes to determine what contents to download. The contents are then stored as block files in the nodes. The query contains the set of attributes and rolled up attributes for the new node. The query receives replies from a subset of the nodes that have the contents needed for the new node. Each reply identifies what subset of the block files is available and the performance characteristics of that replying node. Then the desired contents from the subset of the block files from nodes that are least congested is downloaded.
