Abstract: A session for a mobile station is established by finding a route and determining the availability of resources on the route. Thereafter, active per-hop behaviors (PHB's) are distributed to ports along the route while inactive PHB's are distributed to ports near the route. The active and inactive PHB's provide information on how to route, transport, and process packets belonging to a session. In one embodiment, each of the PHB's indicates a priority level, forwarding port number, rules for discarding packets, rules for sending packets, etc. The packets are transported from one port to another in accordance with the active PHB's, thereby guaranteeing a level of quality of service (QoS). When the mobile station moves to a new location and changes the route, inactive PHB's are activated on the new route. This not only allows mobile stations to communicate at a certain level of QoS even after a move, but also minimizes the delay resulting from the move.

Abstract: For realizing a system for uniformly operating and managing a network system capable of managing a plurality of types of logical networks for one network entity composed of a plurality of objects, information on network topologies is collected from each of the plurality of objects. Display data is created for each of a plurality of types of logical network topologies for each object in accordance with the collected information on network topologies. A control is conducted in accordance with the created display data so as to display a physical connection relationship, a logical connection relationship, and a virtual connection relationship on a virtual screen.

Abstract: A network managing method which divides a network to be managed into a plurality of virtual closed area networks, and defines management information on the virtual closed area networks separately in a plurality of logical hierarchies. A virtual LAN/network space defines a connection state among closed area networks, a closed area space defines attribute information on nodes within a closed area network, and a virtual service defines logical arrangement information on nodes in the overall network. The management information is distributively stored in each node and utilized for communication control and so on. When the configuration of the network is changed due to movements of nodes and so on, an administrator inputs the contents of update from the manager of each layer, so that the manager communicates with a node containing corresponding management information to instruct the node to update the management information.

Abstract: In a network development support system, it is supported that logical hierarchic structure, physical parameters, and logical parameters of a network are integrally designed in an environment in which relationships therebetween can be confirmed. Definition of logical hierarchic structure of the network is accepted in the form of a tree of containers in a container tree window. Physical and logical parameters are accepted in physical and logical object windows, respectively. The physical and logical object windows are created in association with containers of the container trees.

Abstract: A network operating information setting system includes a design device, an automatic setting device and a network device. The design device has the function of producing a command chain of information which an operator designs using a GUI (Graphical User Interface) in order to store the command chain thus produced in a storage medium such as a floppy disk. In addition, the design device also has the function of reading out data from the storage medium in order to display the data thus read out. The automatic setting device has the function of reading out the command chain from the storage medium in order to transmit the command chain thus read out to the network device through a data transmission line. In this connection, an inverse command chain may be produced which is used to restore the network operating information to the original information in the network device.

Abstract: Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.

Abstract: An improved welding method for welding an inner seam of a longitudinally welded steel pipe along an inner groove by welding electrodes held by a boom which is supported by a tracing roller moving along the inner groove of the steel pipe. According to the invention, at least one metal plate is urged against at least one end of the steel pipe after tack welding the seam on an opposite side of the inner groove of the steel pipe to be welded. Lateral angular deformations of the end of the steel pipe are prevented on both sides of the seam. Such deformations are due to the load of the boom when the tracing roller leaves the end of the steel pipe for the metal plate. Thus, the invention provides for prevention of hot cracking at the end of the pipe.
