Problems solved by technology

The traditional solution to time synchronization in the mobile bearer network is to connect a time server to each base station to achieve time synchronization. However, this solution requires the deployment of a large number of time servers and GPS, which is costly and difficult to deploy. Another One solution is to deploy one or several time servers in the bearer network, and the time server transparently transmits time information to the base station through the bearer network. This solution requires that each device in the bearer network must support the precise clock synchronization protocol (English : Precision Time Protocol, PTP) message processing capabilities, and complex protocol state machine operations, which lead to more complex configuration, management and maintenance

Abstract

The present application provides a method and device for compensating time delay. The device determines a first delay value for a first data flow from a first physical port of the device to a second physical port of the device and a second data flow from the second physical port to the first physical port The second delay value, wherein the first delay value is smaller than the second delay value. The device determines a first target latency value based on the first latency value and the second latency value. The device adjusts the delay value of the first data stream to the first target delay value. Through the above method, the device can control the delay value of the bidirectional data flow.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for compensating time delay. Background technique [0002] With the diversification of Internet Protocol (English: Internet Protocol, IP for short) network applications and services, the development of IP networks often needs to meet the demand for higher bandwidth under the existing Ethernet interface rate level. Flexible Ethernet (English: Flexible Ethernet, referred to as: FlexE) technology provides a general mechanism to support multiple Ethernet media access control (English: Media Access Control, referred to as: MAC) rates, and its speed is no longer limited by the physical layer Rate limit, which can meet the needs of various business rates. [0003] In order to solve the problem of ultra-low latency, FlexE cross-connect, as an emerging Ethernet switching technology, is used in scenarios such as 5G mobile service bearing and power relay p...
