Problems solved by technology

[0005] In the existing active / standby interface switchover, after receiving the request message, the management device decides whether to switch between the active / standby physical network ports according to its preset information and the conditions of the device where the active / standby interface is located. In this way, if After switching, the network between the main network port FE2 and the peer end for UDP transmission is unstable, which will make the transmission of UDP in the switched network unreliable

Embodiment 1

[0055] A method for switching between active and standby interfaces. In this embodiment, the active and standby physical network ports are on the same device, assuming that it is a UDP device, and the active and standby physical network ports in the UDP device are respectively connected to different transfer devices LI and L2. The process Figure such as figure 2 shown, including:

[0056] Step 101, the UDP device determines that the network where the active physical network port and the opposite end perform user data protocol UDP communication fails, and sends a request message to the management device to request switching of the active and standby physical network ports;

[0057] The active physical network port of the UDP device can use the active IP address IP_A1 and the active MAC layer address M1 to communicate with the peer through UDP, and the devices LI and L2 connected to the active and standby physical network ports of the UDP device respectively save the active and...

Embodiment 2

[0075] A method for switching between active and standby interfaces. In this embodiment, the active and standby FE physical network ports are not on the same device, assuming that they are UDP1 devices and UDP2 devices, and the active and standby physical network ports are respectively connected to different transit devices LI and L2. Flowchart such as image 3 shown, including:

[0076] Step 201, the UDP1 device determines that the network where the active physical network port communicates with the opposite end through UDP fails, and sends a request message to the management device to request switching of the active and standby physical network ports;

[0077] The primary physical network port of the UDP1 device can use the primary IP address IP_A1 and the primary MAC layer address M1 to perform UDP communication with the peer. The device LI connected to the primary physical network port of the UDP1 device stores the information of the primary physical network port The primar...

Embodiment 3

[0111] A device 3 based on the user data protocol, for example, can be a UDP device, and the general structural diagram of the device is as follows Figure 6 shown, including:

[0112] The second detection unit 30 is used to use the spare physical network port and the opposite end to carry out the user data protocol UDP communication address, and the spare media access layer address, and detect the quality of the user equipment protocol UDP communication between the spare physical network port and the opposite end information; the specific detection method is the same as the method embodiment above.

[0113] The second reporting unit 31 is configured to report the quality information detected by the second detection unit 30 to the management device, so that the management device receives a request to switch the active and standby physical network ports according to the The quality information determines whether it is possible to switch between the active and standby physical ...

Abstract

The embodiment of the invention discloses a method, equipment and a system for switching a main interface and a standby interface, applied to the technical field of communication. In switching of the main interface and the standby interface of the embodiment of the invention, since different addresses for user data protocol communication with an opposite terminal are bound on a main physical network port and a standby physical network port, the standby physical network port can detect the quality of a network for communication with the opposite terminal when the main physical network port carries out the user data protocol communication with the opposite terminal so that management equipment can decide whether to switch the main interface and the standby interface according to the quality of the network for the user data protocol communication between the standby physical network port and the opposite terminal and confirm to switch the main interface and the standby interface when the network has high quality. Accordingly, the invention improves the reliability of the user data protocol communication between the main physical network port and the opposite terminal after the main interface and the standby interface are switched.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method, device and system for switching between active and standby interfaces. Background technique [0002] In the current communication field, physical network ports (FE) are used to transmit UDP packets between devices based on User Data Protocol (UDP). There are active and standby physical network ports on UDP devices (that is, the active physical network Network port FE2), their corresponding media access (MAC) layer addresses are different, in general, only FE1 communicates with the peer end through the network protocol (IP) address and FE1's own MAC layer address; FE1 communicates with the peer end After the network fails, FE2 switches to the active interface, and communicates with the peer end through the IP address and FE2's own MAC layer address. [0003] The active and standby physical network ports in the UDP device are respectively connected to two switched...
