摘要： In an IP packet communication apparatus, an operation and maintenance function capable of monitoring a transmission path is provided to a layer used to process a packet, which corresponds to an upper layer of an optical network. As one method for applying the operation and maintenance function to the packet layer, in the case of IP over PPP over WDM, an operation/maintenance frame is defined to a PPP frame so as to realize the operation/maintenance function of a PPP connection. In the case that a plurality of connections are multiplexed on the same transmission path, a maintenance frame is conducted in order to operate/manage these connections by being grouped, so that a fault occurring in the optical network is monitored. As another method for applying the operation and maintenance function to the packet layer, an operation/maintenance frame is defined to an IP packet so as to realize an operation and maintenance function of an IP flow. Also, since a plurality of flows are multiplexed on the same transmission path, a management packet is defined to operate/manage these flows to be grouped, so that a fault occurring the in the optical network is monitored.

摘要： A communication system including two layers, each having a switching function. The two layers includes lower-layer apparatuses which are connected with communication lines of a lower layer and communication lines of an upper layer and upper-layer apparatuses which are connected with the communication lines of the upper layer. Line failure in the lower and upper communication lines is detected and line switching is coordinated by the line-switching function of the lower and upper-layer apparatuses by using failure information on the lower and upper-layer communication lines.

摘要： An input interface segments a variable length packet into plurality of fixed length cells and generates an internal switching information based on the header information of the variable length packet. The input interface transmits the information to a switch and, after that, transmits the cells as the following cells of the information to the switch. The switch performs switching processing to the succeeding cells based on the information. Therefore, the information is not added to the cells. When an input interface starts to transmit cells generated from a packet to its destination output interface through the switch, the switch is reserved until all the cells arrive at the output interfaces.
摘要翻译： 输入接口将可变长度分组划分成多个固定长度单元，并且基于可变长度分组的报头信息生成内部切换信息。 输入接口将信息发送给交换机，然后将信元作为信息的下列单元发送给交换机。 交换机根据该信息对后续的小区进行切换处理。 因此，信息不会添加到单元格中。 当输入接口开始通过交换机将从数据包生成的单元传输到其目标输出接口时，保留交换机直到所有单元到达输出接口。
