摘要： Methods and devices for implementing Link Pass Through in a point-to-multipoint network in respect of the network reliability field are provided. Embodiments of the present invention are applicable to a network having an access gate, an access device, an aggregation device and a router. When a failure occurs in an active link between the access device and the aggregation device or between the aggregation device and the router, the access device breaks the connection between the access device and the access gate enables a standby link to conduct communication. Advantageously, when a failure occurs in the active link between the access device and the aggregation device or between the aggregation device and the router, the access device may break the connection between the access device and the access gate and the access gate may enable a standby link to conduct communication. Therefore, no matter what type of failure occurs, the embodiments of the present invention may enable a standby link to conduct communication, ensuring thereby communication reliability.
摘要翻译：提供了用于实施链接穿过一个点对多点网络中关于网络的可靠性字段的方法和装置。本发明的实施例适用于在存取栅极具有访问设备向所述聚合设备和路由器的网络。当在一个失败的接入设备与聚合设备之间或所述聚合设备和路由器之间的有效链路上发生时，接入设备打破了接入设备与存取栅极之间的连接使一个备用链路来进行通信。有利的是，当一个故障在接入设备与聚合设备之间或所述聚合设备和路由器之间的活动链路时，接入设备可以打破接入设备与存取栅极和存取栅极可以使待机之间的连接链接进行通信。因此，无论在什么发生类型的故障，本发明的实施例可以使得备份链路进行通信，从而确保通信的可靠性。

摘要： Embodiments of the present invention disclose a method for mapping a packet service onto an optical transport network, including: receiving a packet service message from an access side, and identifying the packet service message by using a first board number of a first line board in which a first egress is located and a first port number of the first egress; sending the packet service message to the first line board corresponding to the first board number; and encapsulating the packet service message that is sent to the first line board, mapping an encapsulated packet service message onto a first optical channel data unit ODU corresponding to the first port number, and sending the first ODU by using the first egress. According to the foregoing technical solutions, cross-connect scheduling of any bandwidth in any direction is implemented based on a packet service, and packet services on different tributary boards share different ODU timeslot or a same ODU timeslot on a same line board.
摘要翻译：本发明实施例公开了一种将分组业务映射到光传送网上的方法，包括：接收来自接入侧的分组业务消息，通过第一线路板的第一单板号识别分组业务消息，定位第一出口并确定第一出口的第一端口号; 向所述第一单板号对应的第一线路板发送所述分组业务消息; 将封装后的分组业务消息映射到与所述第一端口号对应的第一光通道数据单元ODU上，并通过所述第一出口发送所述第一ODU。根据上述技术方案，任意方向带宽的交叉调度都是基于分组业务实现的，不同支路板上的分组业务在同一个线路板上共用不同的ODU时隙或相同的ODU时隙。
