Abstract: A method and an apparatus for determining a data flow rate on a service access port are provided. The method includes: acquiring data traffic information of existing service access ports; classifying the service access ports according to the data traffic information of the service access ports, and determining a data traffic model of a service access port of each class; and when it is determined that a new service access port is to be added to a network, determining a data traffic model corresponding to the new service access port that is to be added, and determining, according to the data traffic model corresponding to the new service access port that is to be added, a data flow rate on the new service access port that is to be added, thus costs of determining a data flow rate on a new service data port to be added can be reduced.

Abstract: A first network device receives a first data packet through an ingress port, and when a first forwarding path corresponding to the first data packet is faulty and there is no redundant path of the first forwarding path on the first network device, sends, through the ingress port of the first data packet, a first notification packet notifying that the first forwarding path is faulty. The first notification packet is generated by a data plane of the first network device, and the first notification packet is a data plane packet. Therefore, a network device that receives the first notification packet processes the first notification packet through a data plane. Then the network device can process a received data packet based on obtained fault information.

Abstract: A link status measurement method includes: A first OLT sends first indication information to a first ONU through a first port. The first ONU is one of at least one ONU included in a PON, and the first indication information indicates a measurement window for measuring the first ONU. The first OLT obtains quality of a signal corresponding to the first ONU. The quality of the signal is quality of a signal received by a second port on a second OLT from a first PON channel in a measurement window, and the first PON channel is a channel carried on a link between the second port and the first ONU. The first OLT determines a status of a backbone link based on quality of a signal corresponding to each ONU in the PON. The backbone link is a common part of a link from the second port to each ONU.
