Synchronization cloud network data transmission control method and control system thereof

Abstract

The invention relates to the cloud network communication technology field and discloses a synchronization cloud network data transmission control method and a control system thereof. The method comprises steps that timing business is sent by a cloud server to a cloud terminal so as to correct a local clock of the cloud terminal according to a message of the timing business, and the cloud server stops sending a timing synchronization message to the cloud terminal when the timing business is sent by the cloud server to the cloud terminal; when the cloud server has no timing business to sent to the cloud terminal, the timing synchronization message is sent to the cloud terminal by the cloud server for at least one time so as to correct the local clock of the cloud terminal according to the timing synchronization message. The method is advantaged in that the timing information is recovered by the cloud terminal through utilizing the characteristics of the timing business, and problems of cloud network terminal synchronization and large transmission cost are solved.

Description

technical field [0001] The invention relates to the technical field of cloud network communication, in particular to the field of synchronous cloud network data transmission. Background technique [0002] In the cloud network, when certain real-time services are transmitted between each cloud server and cloud terminal equipment, such as voice, video and streaming media, etc., it is often necessary to maintain the clock timing synchronization function between the server and the cloud terminal. The terminal needs to continuously transmit timing synchronization information (TSM) to the cloud terminal, so as to ensure that the delay jitter between the server and the cloud terminal is relatively small, and then ensure the service quality of the real-time service of the cloud server played on the cloud terminal. [0003] The general timing synchronization adopts the network timing protocol NTP (Network Timing Protocol), and the more precise timing synchronization is realized throu...

Problems solved by technology

However, NTP or IEEE 1588 transmits timing synchronization information (TSM) through messages. If the messages pass through complex network routing, it will cause clock timing jitter and asymmetrical uncontrollable, making it difficult to recover accurate information from the transmitted messages. The clock is used to ensure the timing accuracy requirements of the cloud terminal. In addition, both the NTP and IEEE 1588 protocols need to send timing synchronization information messages between the server and the cloud terminal in practical applications, which greatly occupies the network transmission bandwidth and improves the network performance. Additional overhead reduces the utilization and throughput of the cloud network's overall business
