    摘要: Upon initialization, a VPC is set up between edge nodes. A control processor of each node creates an IP address/VPC mapping table using IP routing information and an address mapping table mapping correspondence between IP addresses and ATM addresses and supplied by a network management system. A gateway assigns a VCC to each packet input to the network. A sending-side edge node inputs the packet to the VPC corresponding to its destination by referring to the IP address/VPC mapping table. A transit node performs packet switching over VP. A receiving-side edge node transfers each packet to the gateway corresponding to its destination. If a series of packets meet a predetermined condition in a given edge node, its control processor sends VCC information to input interfaces of the edge node so that the packets are switched by an ATM switch in the edge node without intervention of the control processor.

    摘要: Policing method and policing circuit for parallelly conducting a plurality of policing which are dependent on policing items in the policing for defining the traffic of an asynchronous transfer mode network are provided. A plurality of traffic monitor circuits 11 parallelly and independently conduct the traffic monitoring of a plurality of items for the input cell for the communication service to be provided by the asynchronous transfer mode network. Each monitor circuit monitors only the violation of the traffic independently and outputs the result. A total determination circuit determines whether to tag, discard or pass the input cell in accordance with a determination rule prescribed for the communication service based on a CLP value contained in a header of the input cell and the monitor result parallelly obtained from the respective monitor circuits to conduct the policing. Depending on the determination result, the traffic state of the input cell is updated by an update circuit or the result of the polishing is outputted to other apparatus. The policing of the high speed complex communication service provided by the asynchronous transfer mode network having dependency between the monitor items of the traffic and the determination order is attained. A delay burden of the network is reduced by the speed-up of the policing.

    摘要: An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed IP connection, and mobile network IP connection. By using this apparatus of the present invention, cost can be reduced and upgrading to advanced access networks and access services is easily carried out. Provision of the above access nodes implements upgrade-type network services common for diverse protocols. Each access node retains a pathfinding table to which input port, input tunnel identifier and input session identifier entries in a set are registered per session. When routing a packet, by looking up the set of these entries matching with the packet, the associated output port, output tunnel identifier, and output session identifier are obtained. After processing for the packet, appropriate for one of the plurality of access methods and network services, the node forwards the packet over the routed path.

    摘要: An access node run as a packet switching apparatus enables IP connection services for a plurality of access methods; e.g., relatively low-speed IP connection, high-speed 1P connection, and mobile network IP connection.

Provision of the above access nodes implements upgrade-type network services common for diverse protocols.
