Abstract: 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.

Abstract: Embodiments of this application disclose a data transmission method and a communication apparatus. The method may be applied to a data transmission or data distribution scenario in a peer-to-peer P2P network. The method includes: A first end node sends delayed transmission information to a second end node, where the delayed transmission information indicates time information at which the first end node delays sending first data to the second end node. When determining that the second end node accepts the delayed transmission information, the first end node delays sending the first data to the second end node, to alleviate a load of the first end node, so that a network congestion problem caused by a large-scale concurrent data request can be resolved.

Abstract: A method for implementing a GRE tunnel is provided. The access device obtains an address of an aggregation gateway group including at least one aggregation gateway. The access device sends a tunnel setup request in which an address of the access device is encapsulated by using the address of the aggregation gateway group as a destination address. The tunnel setup request is used to request for setting up a GRE tunnel. The access device receives a tunnel setup accept response sent back by an aggregation gateway and obtains an address of the aggregation gateway from the response. The aggregation gateway belongs to the aggregation gateway group. The access device configures the address of the aggregation gateway as a network side destination address of the GRE tunnel. A dynamic setup of a GRE tunnel on an access network that uses an aggregation technology is implemented.

Abstract: In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.
