Disclosed is a first device and a second device each sending BFD echo request packets in an initial stage of establishing communication between the two devices. A method can include determining that a certain mode is detected, such as a low bandwidth mode. The method can be practiced by one or both of the devices or a separate network controller. Based on the detection of the certain mode or the communication link being in a certain mode, the method includes the first device or the second device electing to be a master or a slave. Upon establishing that one of the devices is the master and the other of the devices is a slave, only the master will send BFD echo request packets. 公开了第一设备和第二设备在这两个设备之间建立通信的初始阶段各自发送BFD回声请求分组。一种方法可以包括：确定检测到特定模式，例如低带宽模式。该方法可以由这些设备之一或两者或单独的网络控制器来实施。基于检测到特定模式或通信链路处于特定模式，该方法包括：第一设备或第二设备被选择作为主设备或从设备。在确定其中一个设备是主设备而另一个设备是从设备后，只有主设备将发送BFD回声请求分组。
