A direct-link quality monitoring method to monitor a quality of a direct link between a local device and a peer device in a communication network, wherein the method comprises: determining, by the local device, whether a quantity of neighbors of the local device is the same as a quantity of neighbors of the peer device; if the quantity of neighbors of the local device is different from the quantity of neighbors of the peer device, electing one device, either the local device or the peer device, with a larger quantity of neighbors as a measurement control point, MCP, of the direct link between the local device and the peer device, executing, by the local device, a corresponding monitoring operation, according to whether the local device is the MCP of the direct link, to monitor the quality of the direct link between the local device and the peer device, wherein the monitoring operation comprises: periodically acquiring first data that is generated in a process in which the local device operates in an outbound direction and in an inbound direction of the direct link; and if the local device is the MCP of the direct link, then receiving second data that is of the peer device operating in an outbound direction and in an inbound direction of the direct link and that is periodically sent by the peer device; collecting statistics on the first data and the second data, whereby an operating data of the direct link is obtained; and periodically sending the operating data of the direct link to a network management device; and if the peer device is the MCP of the direct link, then periodically sending the first data to the peer device. determining, by the local device, whether a quantity of neighbors of the local device is the same as a quantity of neighbors of the peer device; if the quantity of neighbors of the local device is different from the quantity of neighbors of the peer device, electing one device, either the local device or the peer device, with a larger quantity of neighbors as a measurement control point, MCP, of the direct link between the local device and the peer device, executing, by the local device, a corresponding monitoring operation, according to whether the local device is the MCP of the direct link, to monitor the quality of the direct link between the local device and the peer device, wherein the monitoring operation comprises: periodically acquiring first data that is generated in a process in which the local device operates in an outbound direction and in an inbound direction of the direct link; and if the local device is the MCP of the direct link, then periodically acquiring first data that is generated in a process in which the local device operates in an outbound direction and in an inbound direction of the direct link; and if the local device is the MCP of the direct link, then receiving second data that is of the peer device operating in an outbound direction and in an inbound direction of the direct link and that is periodically sent by the peer device; collecting statistics on the first data and the second data, whereby an operating data of the direct link is obtained; and periodically sending the operating data of the direct link to a network management device; and if the peer device is the MCP of the direct link, then periodically sending the first data to the peer device.
