Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, these embodiments are provided to explain the principles of the invention and its practical application to thereby enable others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to the particular use contemplated.

Fig. 2 is a flowchart of step S100 according to an embodiment of the present invention. Fig. 3 is a flowchart of step S120 according to an embodiment of the present invention.
Referring to fig. 1, a method for adjusting a network bandwidth of a container according to an embodiment of the present invention includes the steps of:
s100, distributing the network bandwidth m of a system comprising a plurality of containers to each container so as to enable each container to obtain the distributed network bandwidth;
s200, acquiring the actual network bandwidth of each container, and judging whether the actual network bandwidth of each container exceeds the respective preset network bandwidth, wherein the preset network bandwidth of each container is smaller than the respective allocated network bandwidth;
s300, acquiring the number of containers with actual network bandwidth exceeding the preset network bandwidth, and judging whether the acquired number exceeds the preset number; if yes, after the step S400 is executed, returning to the step S100; if not, directly returning to the step S100;
and S400, enabling the network bandwidth m of the system to be m × n, wherein n is a lifting coefficient larger than 1.
Specifically, the system comprises a server, hardware, a plurality of containers and the like, and in order to meet customers in different resource demand fields, a cloud provider integrates a plurality of customers on the same hardware to share resources in order to improve resource utilization rate, that is, the plurality of containers share the server and the hardware resources. Although a significant cost saving is possible, this also brings with it a problem: the containers have the same resource, and are easily interfered when the workload of the containers is large, so that performance interference and low resource utilization rate are caused, the interference is more serious and the performance is more severely reduced along with the increase of the number of the containers which work together at the same time.
In order to prevent the container from reaching the interference critical point, the embodiment of the invention periodically detects the actual network bandwidth of each container of the system, and when the network bandwidths of a plurality of containers of the system exceed the preset network bandwidth, the overall network bandwidth of the system is increased, the network bandwidth of the container is improved, and the container is prevented from reaching the interference critical point.
Referring to fig. 2, the step S100 specifically includes the steps of:
s110, setting an initial weight value for each container in the system;
specifically, in step S110, a weight value is set to each container of the system according to actual needs, so as to allocate a required network bandwidth to each container.
S120, dynamically adjusting the weight value of each container in the system;
and S130, distributing the network bandwidth m of the system to each container according to the weight value of each container.
In order to prevent the containers with high network IO loads and low disk IO loads from affecting the performance of other containers, step S120 further adjusts the weight values of the containers with high network IO loads and low disk IO loads. Step S120 specifically includes the steps of:
s121, detecting disk IO data in a system and network IO data of each container;
s122, judging whether the network IO data of each container is larger than or equal to preset network IO data or not, and meanwhile judging whether the disk IO data is smaller than or equal to preset disk IO data or not; if the network IO data of the container is greater than or equal to the preset network IO data and the disk IO data is less than or equal to the preset disk IO data, performing step S123; if the network IO data of the container is smaller than the preset network IO data and/or the disk IO data is larger than the preset disk IO data, directly performing step S130;
s123, dynamically adjusting the weight value of the container to limit the network bandwidth to which the container is allocated.
As an embodiment of the present invention, the preset number acquiring method in step S300 includes:
when the IO data of the system is larger than the preset IO data, loading the data by different quantities of containers simultaneously;
detecting the average interference strength of containers when different numbers of containers load data simultaneously;
and setting the number of the containers which load data simultaneously when the average interference strength exceeds the preset interference strength as the preset number.
Fig. 4 is a diagram illustrating average interference strength when acquiring different numbers of container loading data for a preset number according to an embodiment of the present invention. FIG. 5 is a graph illustrating average throughput rates for different numbers of container loads at a preset number of times according to an embodiment of the invention. FIG. 6 is a schematic diagram of runtime when a different number of container load data is obtained for a preset number according to an embodiment of the present invention.
As an embodiment of the present invention, for example, in the system of the embodiment of the present invention, different numbers of containers are allowed to simultaneously load data, that is, data is loaded into the database; as can be seen from fig. 4, when the number of containers simultaneously loading data is 6, the average interference strength of the containers exceeds 80%, in this embodiment, the preset interference strength is 80%, that is, in this embodiment, when the number of containers simultaneously loading data reaches 6, the containers are greatly interfered, as can be seen from fig. 5 and 6, when the number of containers simultaneously loading data reaches 6, the average throughput rate of the containers is reduced by 50% compared with that of 5 containers, and the operation time of the containers is increased by 1 time; that is, in the present embodiment, when the number of containers loaded with data at the same time reaches 6, the interference critical point of the containers is reached, and the performance of the containers is seriously affected.
As an embodiment of the present invention, the boosting factor n may take a value of 2, and when a bandwidth increase condition is satisfied, that is, when the number of containers whose actual network bandwidth exceeds the preset number, the network bandwidth M ═ M × n of the system is increased, in this embodiment, the initial system network bandwidth is 1M/s, and the boosting factor is 2. In a first detection period, if a bandwidth condition is met, the network bandwidth of the system is increased to 2M/s; if the second detection period also meets the bandwidth condition, the network bandwidth of the system is increased to 4M/s, and so on, the network bandwidth increased each time is increased by an exponential law of a lifting coefficient, so that the network bandwidth can be quickly restored to a normal level when the whole network bandwidth is greatly reduced.
In this embodiment, the disk IO data, the network IO data, and the system IO data refer to read-write data volume of the disk, read-write data volume of the network, and read-write data volume of the system, and may also be referred to as a disk IO load, a network IO load, and an IO load of the system.
The invention dynamically adjusts the network bandwidth of the container based on the weight value, avoids the container from reaching an interference critical point, and can quickly recover to a normal level when the network bandwidth of the container is wholly and greatly reduced.
