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.
摘要翻译：在初始化时，在边缘节点之间建立一个VPC。每个节点的控制处理器使用IP路由信息和地址映射表来映射IP地址和ATM地址之间的对应关系并由网络管理系统提供的IP地址/ VPC映射表。网关为每个输入到网络的数据包分配一个VCC。发送侧边缘节点通过参考IP地址/ VPC映射表将分组输入到与其目的地对应的VPC。传输节点通过VP执行分组交换。接收侧边缘节点将每个分组传送到与其目的地相对应的网关。如果一系列分组满足给定边缘节点的预定条件，则其控制处理器向边缘节点的输入接口发送VCC信息，使得分组由边缘节点中的ATM交换机切换，而无需控制处理器的干预。

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.
