Abstract: PURPOSE: To provide equipment and its method for large capacity connectionless communication appliable to all the public and private networks. CONSTITUTION: This equipment is provided with a lot of terminal means 30 and 40 for performing the transformation and inverse transformation of connectionless frame transmitted from the network to a cell, requesting the setting of virtual connection when the frame is generated and outputting the cell while using the value of VCI showing the set connection when the connection is set and a lot of connectionless data service means 10 for setting the virtual connection according to the setting request of virtual connection from the terminal means, transmitting the value of set VCI through the terminal means and exchanging the cells transmitted from the terminal means.

Abstract: The terminal devices (30, 40) supply a virtual connection when the data block is produced and provide the cell using a representative channel value which indicates the constructed virtual connection. There are also several data service blocks (50) without connections. Each data service unit is coupled via a virtual path to a bidirectional cell transmitting facility with corresp. coupling selectors. The data service units are coupled together in the form of a complete grid network.

Abstract: The system (12) has a selective multiple transmission function. A cell sub-division device (33) separates and provides a data cell, an operation and management cell (OAM) and a control cell for analysis of applied cells. An OAM processor (35) performs processing of the OAM coming from the cell sub-division device and a connection control device (36) executes a connection command which conforms to the control cell provided by the cell sub-division device. An address header converter (32) is provided to produce a header value from the data cell coming from the cell sub-division device. This is achieved by conversion of this value into a virtual output connection identifier (VPI), a virtual channel identifier (VCI), a multiplex identifier (MID) and a multi-transmission indication value conforming to a destination address. A cell duplicator (37) receives and reproduces a multi-transmission cell having a group address value.

Abstract: A method for protection switching in an Ethernet ring network is provided to solve the problems about ineffective protection switching and settle a transition phenomenon that the quantity of traffic is overshot after the protection switching. A first node, which senses a failure of a link, generates a protection switching frame including an address list of a transfer table corresponding to a port connected to the failed link. Thereafter, the first node transmits the protection switching frame to a port in an opposite direction of the failed link. A second node, which receives the protection switching frame, deletes an address thereof from the address list included in the protection switching frame. Thereafter, the second node corrects a port number of an address, which is included in the address list of the protection switching frame, from addresses of the transfer table corresponding to the port receiving the protection switching frame, or deletes the port number.
Abstract translation: 提供了一种以太网环网中保护倒换的方法，解决了无效保护倒换的问题，解决了保护倒换后流量过大的过渡现象。 检测链路故障的第一节点产生包括与连接到故障链路的端口对应的传送表的地址列表的保护倒换帧。 此后，第一节点将保护倒换帧发送到与故障链路相反方向的端口。 接收保护切换帧的第二节点从包括在保护倒换帧中的地址列表中删除其地址。 此后，第二节点将包含在保护倒换帧的地址列表中的地址的端口号从对应于接收到保护倒换帧的端口的传送表的地址修改，或者删除端口号。
