Traffic forwarding method, device, equipment, medium and program product

By selecting the next-hop device that supports ECN through the pre-established explicit congestion notification neighbor list, ECN tags are added to the data packets, solving the problems of low traffic forwarding efficiency and high latency caused by devices that do not support ECN in the network path, and achieving efficient congestion control and stable transmission.

AI Technical Summary

Technical Problem

When there are some intermediate devices that do not support ECN in the network path, the receiving end cannot obtain congestion information. The sending end is forced to fall back to the traditional packet loss congestion control mechanism if it does not receive the ECN-Echo signal for a long time, resulting in low traffic forwarding efficiency and high forwarding delay.

Method used

The system selects a next-hop device that supports ECN through a pre-established explicit congestion notification neighbor list, adds an ECN tag to the data packet, and sends it to the target next-hop device, ensuring that congestion information can be effectively transmitted to the receiving end. After the receiving end feedbacks, the sending end reduces the sending speed.

Benefits of technology

This improves traffic forwarding efficiency, reduces forwarding latency, maintains stable network operation, and avoids ECN mechanism failure caused by the presence of non-ECN-supported devices in the path.

Abstract

The invention provides a traffic forwarding method and device, equipment, a medium and a program product, and relates to the field of computer networks and communication, and the method comprises the steps: obtaining a data packet corresponding to a traffic forwarding request in response to the traffic forwarding request; detecting whether network congestion exists; if it is determined that network congestion exists, target next-hop equipment is determined based on a pre-established explicit congestion notification neighbor list; adding an explicit congestion notification mark for the data packet; sending the data packet added with the explicit congestion notification mark to a target next hop device; according to the method provided by the invention, the technical effects of improving the traffic forwarding efficiency and reducing the forwarding delay are achieved.
