A method, an apparatus, and a system for measuring a network delay are disclosed. The method includes: acquiring delay measurement information obtained by measuring a service flow by at least one target logical port TLP, where the delay measurement information includes: timestamp information, a service flow identifier, and a TLP identifier; and transmitting the delay measurement information to a measurement control point MCP, so that the MCP determines details about a network delay according to the timestamp information, the service flow identifier, and the TLP identifier. Embodiments of the present application further provide an apparatus and a system for measuring a network delay. Embodiments of the present application achieve direct and accurate delay measurement of a service flow in scenarios of point to point transmission or point to multipoint transmission on the network, and reflect details about a real delay of the service flow.

A communication method and an optical module are disclosed. In various embodiments the method includes generating, by an optical module, a first packet according to a service packet that passes through the optical module, wherein a source address of the first packet is the same as a source address of the service packet, and wherein a destination address of the first packet is the same as a destination address of the service packet; sending, the first packet in a transmission direction of the service packet; and receiving, a second packet sent by the network device, wherein the second packet indicates that the first transmission path from the optical module to the network device exists, and wherein the second packet instructs the optical module to communicate with a network management system by using the network device and the first transmission path.

Provided are a method, apparatus and system for measuring network packet loss, the method includes: acquiring data packet measurement information measured by at least one target logical port to a traffic stream, transmitting the data packet measurement information to a measurement control point, so that the measurement control point determine the condition of network packet loss according to the data packet measurement information. As a data collecting point acquires the data packet measurement information measured by at least one target logical port to the traffic stream, and uniformly transmits the data packet measurement information to the measurement control point, when multiple target logical ports respectively perform measurement to acquire respective data packet measurement information, the measurement control point uniformly determines condition of packet loss of the traffic stream. Therefore, accurate packet loss measurement can be performed on the traffic stream under the scenario of point-to-point, point-to-multipoint or multipoint-to-multipoint networks.

The present invention provides an Ethernet performance detection method and system and an optical network terminal. The method includes: receiving, by an ONT, a detection configuration instruction, and configuring a maintenance end point according to the detection configuration instruction; configuring a performance detection path from the MEP to the VMEP according to states of the virtual maintenance end points configured on a main node and a backup node, wherein the VMEP includes two virtual MEPs, the IDs of the two virtual MEPs are identical, at the same moment; and transmitting a message to a node corresponding to the virtual MEP with the main state. When the node states of the main node and backup node are switched, the optical network terminal may automatically switch the performance detection path to the node corresponding to the virtual MEP, in order to continue to perform the network performance detection.
