    摘要： A router apparatus 5 is provided with an ATM switch, an IP controller for performing routing control as a controller for layer 3, plural kinds of interfaces which are individually provided to plural transmission paths in which various communications are performed, and a cell multiplexing/demultiplexing unit, and manages the cell communications between respective parts on the basis of identification information. The input packet is subjected to IP processing in an interface to be converted to a cell in a common format, and the cell is serially multiplexed with a cell from another interface on a cell basis, and transmitted to the ATM switch at the cell multiplexing/demultiplexing unit. Each interface and each cell multiplexing/demultiplexing unit sets and switches the identification information for the header portion of the packet and the cell to be communicated by using a table in which the corresponding relationship of the identification information is registered.

    摘要： In a system in which communication is performed among a plurality of devices having a mechanism of disassembling a packet into ATM cells to send them and a plurality of devices having a mechanism of assembling the received ATM cells into the packet, a frame is prevented from being lost owing to change of virtual connections in the course of transferring the frame, improving reliability of the communication on the packet level. When the switch receives a request for change of switching, it does not processes that request at once, but confirms that the cell located at the boundary of the frame has been processed, before processing the change request, so as to protect the frame. When the switch receives a request for change of switching, it protects a frame by multicasting the cells to both destinations before change and after change, for a given period of time.

    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。
