Problems solved by technology

[0004] In practice, it has been found that the periodic active heartbeating of the safety direct device will increase the load on the central processing unit (CPU) of the safe direct device, and the BYPASS device adopts the pure relay method to realize the link switching, which will also cause the renegotiation of the upstream and downstream ports. , so that the link switching time is too long, which may lead to the loss of important data of customers

Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] Embodiments of the present invention provide a link switching method and related devices and systems. The method, device and system do not need to renegotiate the upstream and downstream ports during link switching, and can realize fast link switching and avoid excessive link switching time. The long-term loss of important customer data can also save the safety direct device from periodically sending heartbeats, effectively reducing the CPU load of the s...

Abstract

The embodiment of the invention discloses a method and a related device for switching over links. The method comprises the following steps that bypass equipment receives a link switchover command sent by safe forthright equipment; the safe forthright equipment responds to the link switchover command, routes business dataflow input from a first-side Ethernet port to the bypass equipment; and the business dataflow is output from a second-side Ethernet port after being processed by the bypass equipment, wherein the bypass equipment and the safe forthright equipment share the first-side Ethernet port and the second-side Ethernet port.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a link switching method and related devices and systems. Background technique [0002] On the Internet, in order to effectively eliminate security risks such as viruses, Trojan horses, spam, and hacker attacks, Unified Threat Management (UTM), Intrusion Protection System (Intrusion Protection System, IPS), and distributed Security inline devices such as Distributed Denial of Service (DDOS) or Deep Packet Inspection (DPI). Deployed on network links, these secure inline devices can detect, analyze, and filter network traffic and other security services to ensure network security and reliability. However, the deployment of these secure IDC devices will also introduce new faulty nodes to the Internet. When these IDC devices fail or abnormally lose power, the network link will be interrupted, resulting in serious consequences. The introduction of bypass (BYPASS) equipme...
