摘要： Network interconnection apparatus and method capable of efficiently guaranteeing optimum QoS suited to the status of actual traffic and network, whereby high-performance network interconnection is achieved without entailing lost calls. Routing information managing means manages routing information of an ATM network, and statistical information managing means manages statistical information on the traffic of a LAN. QoS setting means sets QoS which the ATM network ought to guarantee, based on the statistical information, and QoS guarantee determining means determines based on the routing information whether or not the set QoS can be guaranteed. If it is judged that the QoS cannot be guaranteed, QoS adjusting means adjusts the QoS so that the QoS can be guaranteed. Call connection control means connects call according to the QoS which can be guaranteed.

摘要： In a node device having a function of recognizing route information of a network, a route selector selects a connection setting route based on the dynamic route information of the network, and generates a reservation request of a predetermined optimum route unless the connection setting route is the predetermined optimum route, a route switchover reservation portion monitors whether or not the predetermined optimum route becomes available based on the route information during the communication, and makes switchover instructions toward the predetermined optimum route to a call processor. The call processor sets a connection in a selected connection setting route, and sets another connection in the predetermined optimum route by the switchover instructions.

摘要： A routing system includes a route information management unit for managing standardized network route information, an event processing unit for managing event information obtained by detecting and statistically processing events in a local node, and a routing unit for designating an optimum route for a call connection request based on the standardized network route information managed by the route information management unit and the event information managed by the event processing unit. Hence, the routing system can designate a higher-quality route than that designated only by the route information managed by the route information management unit and the convenience of the node can be improved.

摘要： A sending probe sends a quality measurement packet to a receiving probe, and increments a sent packet counter every time the quality measurement packet is sent. A receiving probe receives the quality measurement packet from the sending probe, and attaches a received packet counter to the quality measurement packet and returns the quality measurement packet to the sending probe. The sending probe receives a returned quality measurement packet, extracts a received packet count from the quality measurement packet, and calculates a packet loss rate by using a difference between the sent packet counter and the received packet counter and a difference between the received packet counter and the returned packed counter.

摘要： In an exchange system which performs a communication based on personal identification information for identifying respective subscribers, the invention has an object of providing a system which can flexibly accommodate a change of the communication terminal of actual use by a movement, for instance, of a calling-side subscriber or a call-receiving-side subscriber. A camp-on communication managing apparatus of the invention has a personal position registration table in which terminal identification information for identifying a communication terminal registered to a subscriber for each personal identification information for identifying the subscriber is registered, and manages communication terminals used by respective subscribers. Thus, a camp-on communication can be established even where a camp-on-registered subscriber changes his communication terminal of actual use.

摘要： A control PVC is set up on a line connecting between exchange units, and periodic communication is performed between the exchange units using the control PVC. The periodic communication is monitored at each exchange unit for detection of a line failure and, at each exchange unit, a connection on the line is automatically switched over to a reserve connection in the event of a line failure. For manual switchover of a connection set up between the exchange units, a manual switchover request is issued from a maintenance console connected to one of the exchange units and, in response to the request, switchover request information is sent to the other exchange unit. The exchange unit that received the switchover request information switches the connection over to a reserve connection, and returns a switchover completion notification. The exchange unit that received the switchover completion notification switches the connection over to a reserve connection.
