摘要： An ATM switch and a congestion control method are provided to handle connection setup requests from other ATM devices. In the ATM switch, a congestion detecting process detects congestion of a class that has a number of the connection setup requests stored by class in the buffer equal to T(x), a predetermined number of the connection setup requests to be stored for each of the classes. A message discarding process discards the received connection setup request if it belongs to the congested class. Furthermore, a priority control method for receiving connection setup requests is provided to establish connections more efficiently. A branching process detects a port to which the connection setup request is inputted, identifies a priority class which corresponds to the port using a priority table, and stores the connection setup request in one of queues which are provided for each priority class. An extracting process extracts the connection setup request from the queue of the priority class to be extracted according to a predetermined algorithm.

摘要： Switches create and manage routes with route control protocols such as BGP-4, PNNI, etc. and a route management apparatus is notified of the information of the routes, created by these protocols, and the route management apparatus verifies the validity of a route of which the apparatus is notified by a switch based on the route information of the whole network composed of the plurality of pieces of information given by respective switches and the management policy set by a network manager. In the verification of validity, it is confirmed that the transmitted data are able to arrive at the destination securely and the set route is not against the management policy, and the route-usage-permission-notice of a route confirmed of its validity by the route management apparatus is transmitted to respective switches. Thereby, in the route control of a network using a route control protocol, it is made possible to prevent the occurrence of an abnormal route caused by the difference in the speed of operations of respective switches or an erroneous setting of a switch.

摘要： The object of the present invention is to provide a communication network system that reduces the burden of entering settings for the network system. A service directory server in the communication network system provides unified management of the service information of the service-providing server installed in the network. The service information managed by the service directory server is distributed to the communication nodes either automatically or in response to requests from a communication node. The communication nodes receive packets and, for received packets that are addressed to itself, a service-providing server destination is determined based on the service information provided by the service directory server and the packet is transferred to the server to receive the service.

摘要： In a packet transmission router used in a VRRP (Virtual Router Redundancy Protocol) network having a VR (Virtual Router) function, when virtual routers VR are realized by the VRRP, the routing control information that each VR manages is prevented from being mixed with that of other VR. When an active packet transmission router transmits a VRRP packet to a standby packet transmission router, an identifier indicating which virtual router belongs to the VRRP packet is added to the VRRP packet before the transmission of the VRRP packet.

摘要： An object of the present invention is to solve a problem that when multicast is utilized in a network configured with virtual routers, traffic in the relay network is increased. According to the present invention, the number of multicast packets via the relay network is reduced by performing a multicast packet transfer across the virtual routers within the same router. Specifically, it is allowed to register in a multicast routing table held by each virtual router, a line interface identifier of another virtual router as outgoing line interface information, whereby multicast packet transfer from a virtual router to another virtual router is made possible. In order to specify a virtual router to share the multicast packet, each virtual router holds information to specify a virtual router having a line interface to receive the multicast traffic indicated by the multicast group address.

摘要： In a broadband access network, calls can be kept active even when a telephone network fails. A voice gateway function captures callee telephone number information sent from a caller subscriber telephone to the telephone network and, when the telephone network fails, keeps the call active by retaining the connection between the caller and the callee. Furthermore, when the telephone network fails, the operation mode of the voice gateway and all ONTs is switched from an H.248 gateway mode to an SIP softswitch mode, allowing the voice gateway function to relay communication packets between ONTs and new call connections to be made in the broadband access network.
