the management device 103 acquires information of each flow rate generation device 102, and transmits the information of each flow rate generation device 102 to the control device 101.
The network test platform traffic generation system of the embodiment of the present invention further includes a management device 103, and the management device 103 may be a processor having functions of acquiring information and processing information. The management device 103 can acquire information of each flow rate generation device 102 at regular time intervals and transmit the information of each flow rate generation device 102 to the control device 101. The information of the traffic generation device 102 includes: identification, address, port, CPU (Central Processing Unit/Processor) utilization, memory utilization, and bandwidth utilization, among others.
For example, the management apparatus acquires the CPU usage rate, the memory usage rate, and the bandwidth usage rate of each traffic generation apparatus 102 every 60 seconds, then updates original data in the database, and transmits the acquired information to the control apparatus 101.
Control means 101 for:

The control device 101 can manage the obtained information of each flow rate generation device 102. For example, an information table is created, and information of each traffic generation device 102 is stored in accordance with the identifier or number of the traffic generation device 102.
Upon receiving the traffic generation request, the control device 101 analyzes the traffic generation request to obtain parameter information included in the analyzed traffic generation request, and determines whether or not information of the target traffic generation device is included in each obtained parameter information. The information of the target traffic generating device may be an identifier of the target traffic generating device, an address of the target traffic generating device, or a port of the target traffic generating device. The target flow generating device is a flow generating device 102 designated to generate a target flow.

Before calculation, a flow generation device set included in the network test platform flow generation system according to the embodiment of the present invention may be preprocessed, where the preprocessing includes:
1) deleting a source flow generating device corresponding to a flow generating request sending end from a flow generating device set;
2) the traffic generating device set is traversed to see if the utilization of the CPU, memory, and bandwidth of each traffic generating device 102 exceeds the threshold (e.g., 80%) set by the network test platform traffic generating system. If a certain index item of the flow volume generation device 102 exceeds the threshold value, it means that the flow volume generation device 102 is in a high load state in some respect, and is not suitable as a generation target flow volume generation device, and therefore the flow volume generation device 102 is deleted from the flow volume generation device set.
Specifically, the load of each flow generating device 102 may be calculated using the following preset formula:
the preset formula is as follows:
Load＝x1×C+x2×M+x3×B
wherein Load represents the Load of the flow generating device 102; c represents the CPU utilization of the central processing unit of the flow generating device 102; m represents the memory usage of the traffic generating device 102; b represents the bandwidth usage of the traffic generating device 102; x is the number of1Indicating the proportion of the CPU index item of the flow volume generation device 102; x is the number of2Represents the proportion of the memory index item of the flow generating device 102; x is the number of3Indicates the proportion of the bandwidth index item of the flow generating device 102, and satisfies x1+x2+x3＝1。
The preset number of flow generation devices 102 having the lowest load is specified as a target flow generation device that generates a flow in response to the flow generation request.
In this step, assuming that a target flow needs to be generated in a network experiment platform flow generation system including M flow generation devices 102, a preset number N of target flow generation devices participating in generating the target flow is set (M > N ≧ 1), and a user can generate the target flow in the N target flow generation devices after wishing to initiate a flow generation request, where the flow generated by each target flow generation device is T.
The input of the algorithm is a flow generation device set VM ═ VM included in a flow generation system of a network test platform1,vm2,…,vmMWhere vm isi(i-1, 2, …, M) represents the ith flow rate generation device. The load of each flow generating device 102 is obtained by the above preset formula calculation. The loads of the traffic generation devices 102 are sorted from small to large, and N traffic generation devices 102 with low loads are selected from the queue and output as the target traffic generation device in the embodiment of the present invention. I.e. the set VM' of the target traffic generating device, { VM ═ VM1,vm2,…,vmNWhere vm isi(i-1, 2, …, N) represents the i-th target flow rate generation device.
And selecting a flow generation tool matched with each parameter information from a plurality of flow generation tools preset by the target flow generation device according to each parameter information obtained by analyzing the flow generation request as a target flow generation tool.
Optionally, the target traffic management device is specifically configured to receive the control file, and generate a target traffic corresponding to the traffic generation request by using a target traffic generation tool of the target traffic generation device.
Therefore, the embodiment of the invention can screen out each low-load target flow generation device for generating the target flow, and further generate the target flow through the target flow generation tool in the target flow generation device, thereby ensuring the reasonable use of the resources of the system and improving the performance of the system.
