Static vehicle-mounted Ethernet switch message forwarding method, system and computer

Abstract

The invention provides a static vehicle-mounted Ethernet switch message forwarding method and system and a computer, and the method comprises the steps: constructing a network topology model which comprises a total network, the total network comprises a plurality of network nodes, and the network nodes comprise switches; identifying VLAN ID information in a message sent by a vehicle-mounted Ethernet through a switch, and respectively setting a corresponding forwarding rule for data flow of each VLAN; and identifying a corresponding message type according to the VLAN ID information in the message, and statically forwarding the message data to a preset corresponding message target port according to the message type and the forwarding rule. According to the static vehicle-mounted Ethernet switch message forwarding method provided by the invention, the message data can be statically forwarded to the preset corresponding message target port according to the message type and the forwarding rule, so that the message can be rapidly, efficiently and reliably forwarded in the vehicle-mounted Ethernet.

Description

Technical field [0001] Technical Field The present invention relates to data processing, and particularly to a static vehicle Ethernet switch message forwarding method, system and computer. Background technique [0002] With the rapid development of electronic, intelligent and networked vehicles, scale and complexity of the in-vehicle electronic systems is growing. Among them, on-board Ethernet backbone network technology is expected to become the future intelligent vehicles. With the introduction of TSN and seamless redundancy technology, on-board Ethernet for network failure with a stronger fault tolerance. [0003] However, redundant links existing vehicle electronic system will lead to the interior of the Layer 2 network loops, and traditional packet forwarding mechanism during transmission, the broadcast storm problem prone, and thus render the network failure. Although the prior art introduced in the TSN seamless redundancy protocol in a new forwarding method can eliminate ...

AI Technical Summary

Problems solved by technology

[0003] However, the redundant links in the existing in-vehicle electronic system will cause loops in the internal two-layer network, and in the process of sending messages using the traditional forwarding mechanism, problems such as broadcast storms are prone to occur, thus causing the network to fail

Although the existing technology introduces a new forwarding method in the seamless redundancy protocol in TSN, which can eliminate the forwarding problem caused by redundant links in the network, it requires the hardware support of the switch, and it will also cause network traffic to appear. Unstable phenomenon, so it cannot be applied to existing in-vehicle networks
