Method and network device for measuring delay

Abstract

The present application provides a method for measuring time delay and a network device. The method includes: a first network device receives a first service flow; the first network device determines a first A time delay value, where the first time delay value is a time difference between the first moment and the second moment when the first measurement code block is detected in the first network device. Based on the above technical solution, the network device can determine the delay value of the service flow by measuring the delay value of the measurement code block in the service flow.

Description

Technical field [0001] The present application relates to the field of information technology, and more particularly, to a method and a network delay measurement devices. Background technique [0002] Interleaving virtual sub-layer (virtual interleaving sub-layer, VIS) technology in itself is a time division multiplexing media access control layer (media access control, MAC) or less, the MAC layer below the slotted channel. After slotted, can be transmitted using the low-speed industrial Ethernet service slotted channel. But slotted bring common way delay uncertainties that business relations random arrival time and transmission time slots, resulting in service delays uncertain. [0003] When the service is mapped to the VIS in the slot, export business mapping and caching will delay the introduction of uncertainty. With the increase in the number of cascaded devices, uncertainty will delay cumulative, resulting in lowering the communication efficiency. Inventive content [0004...
