Vehicle-mounted network load balancing method based on TBOX and mobile phone

Abstract

The invention discloses a vehicle-mounted network load balancing method based on a TBOX and a mobile phone. Connection is established between a mobile phone and a cloud server, between a TBOX and themobile phone, and between the TBOX and the cloud server. The mobile phone reports a local redundant bandwidth to the TBOX, and meanwhile, the mobile phone receives and installs an encryption program sent by the TBOX; the TBOX configures a routing rule and a QoS strategy; and when the TBOX monitors a condition of triggering load balancing, the vehicle condition big data of partial flow is routed toa mobile phone according to the QoS strategy, and the data is uploaded to a cloud server by the mobile phone through the encryption program. According to the invention, the data transmission link isestablished among the TBOX, the mobile phone and the cloud server, and the load balancing of the uploading of the vehicle-mounted big data is realized on the link layer, thereby greatly reducing the expenditure of the hardware and kernel resources of the TBOX, and providing high reliability, stability and real-time guarantee for the data interaction between the vehicle end and the cloud end.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a load balancing method for a vehicle network based on a TBOX and a mobile phone. Background technique [0002] With the deployment and application of Internet of Vehicles, intelligent network and intelligent driving, the amount of data that needs to be interacted with the network side in the car is increasing. These data directly determine the judgment of vehicle health, driver's physiological condition and intelligent driving decision-making. And execution directly affects the driving status of the vehicle and the personal safety of the occupants. In this context, the integrity and timeliness of data transmission in the vehicle must be guaranteed. [0003] At present, TBOX, as the only network node, bears the data transmission between the Internet of Vehicles and the vehicle terminal. At the same time, it also undertakes important functions such as remote contro...

AI Technical Summary

Problems solved by technology

The uplink bandwidth of the 5G module is much higher than the processing speed at which TBOX reads data from the hardware link and then performs data routing at the kernel or application layer. The processing of data inside TBOX becomes the efficiency bottleneck on this complete transmission link. In the case of massive data transmission concurrently with the above-mentioned other services, it is bound to bring huge pressure on the network bandwidth occupancy rate and CPU occupancy rate of TBOX. In the case that these two resources cannot be guaranteed, the stability and integrity of data transmission It is also difficult to guarantee timeliness, and other concurrent functions also face the risk of being terminated abnormally due to insufficient resources, which affects various decisions and calculations based on vehicle data in the entire Internet of Vehicles solution.
