Please refer to fig. 3, which is a flowchart illustrating a network quality testing method applied to the network quality testing apparatus shown in fig. 2 according to a preferred embodiment of the present invention. The specific flow shown in fig. 3 will be described in detail below.

Step S101, a network quality measurement request of a data link between two target network devices in a plurality of network devices is initiated.

In the embodiment of the present invention, when a network quality test needs to be performed on any two network devices 300 of the plurality of network devices 300, the first network controller 100 may initiate a network quality measurement request for a data link between the two target network devices.

Specifically, the first network controller 100 may preset to automatically perform the network quality test on any two target network devices in the plurality of network devices 300 at predetermined time intervals. In operation, the first network controller 100 automatically initiates a network quality measurement request for a data link between any two target network devices at predetermined time intervals.

The first network manager 100 may also be responsive to a triggering event to initiate a request for data link network quality measurements between any two target network devices of the plurality of network devices 300. For example, a network administrator may access the first network hypervisor 100 through a terminal device (e.g., a computer), and send a control instruction to the first network hypervisor 100, where the control instruction indicates to test the network quality of a data link between two target network devices, and the first network hypervisor 100 initiates the network quality measurement request according to the control instruction. For another example, when the path for sending the message needs to be recalculated, the first network manager 100 may also initiate a network quality measurement request for a data link between two target network devices of the plurality of network devices 300.

In an embodiment of the present invention, a network quality measurement request for a data link between two target network devices of the plurality of network devices 300 is initiated by the first network hypervisor 100. It will be appreciated that in other embodiments, a network quality measurement request for a data link between two target network devices of the plurality of network devices 300 may also be initiated by the second network hypervisor 200. Triggering and constructing a special test message, sending the special test message to the network device 300 through the first network management controller 100 or the second network management controller 200, driving the network device 300 to send the test message to the destination network device 300 according to the network quality measurement request, and forwarding the message to the first network management controller 100 or the second network management controller 200 to calculate the network parameters of the link after the destination network device 300 receives the message.

And step S102, obtaining the network quality of a data link between two target network devices according to the obtained network parameters.

After initiating the network quality measurement request, the first network controller 100 obtains the network parameters and performs a comprehensive operation according to the obtained network parameters to obtain the network quality of the data link between the two target network devices. The network parameters include network parameters of ports of the network device 300 and network parameters of links of the network device 300.

The first network controller 100 is communicatively connected to each network device 300, and therefore can directly or indirectly obtain the network parameters of the ports of all the network devices 300. The network parameters include at least one of link media of the network device 300, port modes (such as rate, full duplex/half duplex, optical/electrical interface, etc.), maximum bandwidth, real-time used bandwidth, and data packet statistics (including number/byte of transmitted packets, number/byte of received packets, number/byte of unicast packets, number/byte of multicast packets, number/byte of broadcast packets, number/byte of error packets, etc.). The port modes, the maximum bandwidth, and the real-time used bandwidth of the network device 300 may be directly obtained, and the size distribution of the data packets may be obtained by analyzing the transmission condition of the data packets over a period of time.

Through the process of constructing the dedicated test packet and transmitting the dedicated test packet from one network device 300 to another network device 300 at least once, the obtained information of the network link, such as delay, jitter, packet loss, throughput of a specific UDP/TCP protocol, and the like, is used as the network parameter of the link.

After the network parameters of the ports and the links of all the network devices 300 are obtained, the first network controller 100 performs a comprehensive operation according to the network parameters of the ports and the links of all the network devices 300 to obtain the network quality data of the data link between the two target network devices. For example, if there are 10 data links from the target network device a to the target network device B, the network quality of the data link between the two target network devices may be 10, and each data link corresponds to one data link. Or the first network manager 100 selects the network quality of several data links with better network quality as the network quality of the data link between the two target network devices. The network quality comprises parameters such as network delay, jitter, packet loss rate, throughput of a specific UDP/TCP protocol, port network parameter statistics and the like.

In the embodiment of the present invention, after obtaining the network quality of the data link between the two target network devices, the first network controller 100 may further send the network quality of the data link between the two target network devices to a terminal device at a network administrator side for the network administrator to use.

Step S103, obtaining a data communication path between the two target network devices according to the network quality of the data link between the two target network devices.

After the network quality of the data link between the two target network devices is obtained, the first network controller 100 performs path calculation in the control protocol on the network quality of the data link between the two target network devices, so as to obtain a communication path with excellent data communication capability between the two target network devices.

It is understood that in other embodiments, the first network hypervisor 100 may also send the network quality of the data link between the two target network devices to the second network hypervisor 200 for use by the second network hypervisor 200 in performing path computations in the control protocol.

Step S104, when the management and control of the function of at least one of the network devices satisfies the management and control switching condition, loading/handing over the management and control of the function satisfying the condition.

In the embodiment of the present invention, the first network controller 100 may control all the network devices 300, and the second network controller 200 may control the corresponding network devices 300. The first network manager 100 and the second network manager 200 can select a function of the same network device 300 to manage. For example, the first network hypervisor 100 and one of the second network hypervisors 200 together govern 10 functions of a target network device, wherein the first network hypervisor 100 governs 7 functions of the target network device, and the second network hypervisor 200 governs the remaining 3 functions of the target network device.

When the first network controller 100 fails to control a certain function of at least one network device 300, the first network controller 100 transfers the control authority of the certain function to the second network controller 200 corresponding to the network device 300 with the failed function for control. When the second network controller 200 fails to control a function of the corresponding network device 300, the first network controller 100 loads the failed function of the network device 300.

For example, in the process of managing a certain network device 300, the function X of the network device 300 is originally managed and controlled by the first network controller 100, when the second network controller 200 corresponding to the network device 300 detects that the management and control of the function X of the first network controller 100 is failed, the second network controller 200 corresponding to the network device 300 acquires a function and data list for operating the function X at this time, and loads and operates the function and data list after acquiring the function list, thereby completing the handover of the management and control authority.

For another example, when measuring the network quality of a data link between network devices 300 near a second network controller 200, the right of the network device 300 originally managed by the first network controller 100 may be handed over to the second network controller 200 of the network device 300, that is, the second network controller 200 constructs a dedicated test packet, the dedicated test packet is sent to the network device 300 through the second network controller 200, the network device 300 is driven to send the test packet to the destination network device 300 according to the network quality measurement request, and the destination network device 300 receives the dedicated test packet and forwards the dedicated test packet to the first network controller 100 or the second network controller 200 to calculate the network parameters of the link.

In the embodiment of the present invention, for example, when one of the network hypervisors sends an ICMP message to a certain network device 300, the policing authority of the function is also handed over according to the situation. Specifically, the location restrictions of the two network managers may be given, and the handover of the management authority may also be operated based on the consideration of the processing efficiency. For example, when the load of one of the network managers is excessive, the sending control authority of the ICMP message may be handed over to the network manager with a lighter load; the control authority of the ICMP function may also be handed over to a network controller closer to the network device 300 to save the bandwidth resource of the network.

In this way, by handing over the authority for controlling the functions of the network device 300, it is ensured that the most suitable network controller controls the network device 300 in real time.

In the embodiment of the present invention, the first network controller 100 and the second network controller 200 have the same functions. Therefore, the method described above in the embodiment of the present invention may also be executed by the second network controller 200, and a detailed description thereof is omitted in this embodiment.

The right management module 115 is configured to, when the management of the function of at least one of the network devices satisfies the management switching condition, load/hand over the management of the function satisfying the condition.
