摘要： The present invention provides a delay measurement method of a network node device, a delay measurement apparatus, and the network node device. The delay measurement apparatus separately performs corresponding delay measurement on a node delay value generated when a packet is transmitted from an ingress port of the network node device to an egress port of the network node device. Serviceability, availability, and reliability of delay performance of the network node device can be evaluated based on obtained delay measurement data. Therefore, precise quantitative evaluation and monitoring of delay reliability of the network node device can be completed based on comprehensive delay measurement data.

摘要： This application discloses a delay measurement method and device. A physical layer chip of a first physical port of a network device receives a packet and sends a first time stamp and the packet to a Media Access Control MAC chip of the first physical port. The MAC chip of the first physical port adds the first time stamp to the packet and sends the packet. A MAC chip of a second physical port receives the packet, extracts the first time stamp of the packet, and sends the packet to a physical layer chip of the second physical port. The MAC control chip of the second physical port receives a second time stamp of the packet. The network device calculates a processing delay for the packet. The processing delay is a value obtained by subtracting the first time stamp from the second time stamp. In this way, the delay used by the network device for processing the packet is accurately measured.

摘要： This application provides a latency-based transmission path control method, an apparatus, and a system. Device latencies of network node devices on an active transmission path, device latencies of network node devices on a standby transmission path, latencies of links between the network node devices on the active transmission path, and latencies of links between the network node devices on the active transmission path are obtained, and calculation is performed based on the respective device latencies and link latencies to obtain an active transmission path latency and a standby transmission path latency. Then, based on a latency-based switching mechanism, when the active transmission path latency is greater than a switching threshold and the standby transmission path latency is less than the switching threshold, an active-to-standby path switching command is generated, and a packet is switched from the active transmission path to the standby transmission path for transmission based on the active-to-standby path switching command. In this way, protection is provided for a transmission path of a latency-sensitive service, thereby ensuring a service requirement of a service transmission path on a latency.
