Background
A software defined network (Software Defined Network, SDN) is a new network architecture, the core idea being to control the distributed forwarding network device plane by means of controller software.
In SDN-defined networks, where high-load access traffic is involved, load balancing is typically employed to split the access traffic to multiple service providers (e.g., background servers). For load balancing, there is usually pure software, such as LVS, nginx, HA-Proxy, etc., and pure hardware, such as F5, a10, deep belief, etc., each of which has advantages and disadvantages.
For the load balancing software, because the SDN controller can only receive one load balancing software, when a new demand occurs to a user, because the protocols supported by the load balancing software are limited, if the load balancing software cannot support the protocols in the new demand, the load balancing software cannot be used continuously, so that when the load balancing software is received by the SDN controller, the new demand of the user cannot be met timely, and the receiving efficiency is low.
Meanwhile, under the condition of only one type of load balancing software, the actual requirement of a user is not considered, for example, the load balancing software needs to meet the performance of high concurrent traffic at first, but if the later user has access service with low concurrent traffic, the load balancing software is adopted to perform load balancing, so that the performance of the load balancing software is wasted.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Some embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a load balancing software nanotube method based on SDN according to an embodiment of the present application. The method can be applied to different business fields, such as the internet financial business field, the electric business field, the instant messaging business field, the game business field, the public business field and the like. Some input parameters or intermediate results in the flow allow for manual intervention adjustments to help improve accuracy.
Currently, more and more services have been clouded, and the clouded services run in virtual machines. But single virtual machines have weak concurrent access. In public cloud environments or larger scale private cloud environments, there are portions of concurrent operations that need to support high data volumes, thousands, even hundreds of millions, of concurrent access requests per second. In this case, the cloud environment generally processes the concurrent service by copying a plurality of virtual machines running the service, but this method needs to deploy a set of load balancing in front of a plurality of virtual machines running the service, and distributes the original access to the same service to the virtual machines running the service for processing after a certain algorithm.
However, at present, an SDN scheme in public cloud or private cloud generally uses a network virtualization scheme in an area, and only one load balancing scheme is available. Therefore, in a region, if multiple services face concurrent access requirements of different magnitudes, the same load balancing scheme is used to cope with the concurrent access requirements, for example, when the services are provided by using the same load balancing software in the face of different concurrent volume requirements, high concurrent performance of the software may be wasted, and access bottlenecks may be caused by insufficient concurrent performance of the software. And in the face of the load balancing concurrent service requirement of a new protocol, when the existing load balancing software does not support the service requirement, the scheme of single load balancing software has no way to deal with. Based on the above, in order to solve the above problems, the present application provides a load balancing software nanotube method based on SDN.
The flow in fig. 1 may include the steps of:
s102: the SDN controller obtains the access request of the user. The access request comprises access parameters and access services required by the user during access.
S104: and creating an initial virtual network and an initial folder through an encapsulation isolation technology.
S106: respectively matching preset identifiers of the load balancing software of the plurality of nanotubes with the access parameters to determine the load balancing software to be started; and the preset identifier is used for representing a supporting protocol of the load balancing software and supporting concurrent traffic.
The method comprises the steps that a user tags load balancing software in advance, concurrent flow which can be supported by the load balancing software is identified, protocol is supported, and aspects of adequacy are supported, so that preset identification of the load balancing software is obtained.
Specifically, the communication protocol in the access parameters is first determined, then the supporting protocols of the plurality of managed load balancing software are respectively matched with the communication protocol, and the effective load balancing software is determined.
Then, concurrent traffic in the access parameters is determined, and a difference between the supported concurrent traffic of the payload balancing software and the concurrent traffic in the access parameters is determined. For example, the difference between the supported concurrent traffic of the payload balancing software and the concurrent traffic in the access parameters is calculated by a preset formula. And finally, taking the effective load balancing software with the smallest difference value as the load balancing software to be started. Thus, the concurrent access requirement of the specific communication protocol is realized, and only the service of the specific protocol is provided.
S108: and calling a preset configuration template of the load balancing software to be started, and generating a configuration file of the load balancing software to be started according to the preset configuration template and the access parameters.
The preset configuration template comprises a virtual IP address, a virtual network port number and the like of the load balancing software to be started.
S110: and creating a virtual network port and a process space by using an encapsulation isolation technology.
S112: and adding the virtual network port into the initial virtual network to obtain a starting virtual network, and adding the configuration file into the initial folder to obtain a starting file.
S114: and starting the load balancing software to be started according to the starting virtual network, the starting file and the process space.
In some embodiments of the present application, after starting load balancing software to be started, a load balancer is obtained according to the software to be started, and then, based on a preset load balancing model, a virtual machine server to be provided with an access service is determined among a plurality of virtual machine servers. Then, the access request is forwarded to the virtual machine server that is to provide the access service through the switch according to the preset virtual IP address.
More intuitively, fig. 2 is a system structure diagram of an SDN-based load balancing software nanotube provided by the present application. As shown in fig. 2, the network server includes a load balancer 1, an sdn controller nanotube and two load balancing software, and both load balancing software are started to obtain the load balancer 1 and the load balancer 2 respectively.
For the access between the internal networks, the VM3 in the left virtual machine server initiates an access request to the load balancer 1, and the load balancer 1 is connected with the VM1 of the right virtual machine server through the network 1 and the switch, that is, the VM1 of the right virtual machine server is the virtual machine server that will provide the access service, and the VM1 of the right virtual machine server returns the access result to the VM3 of the left virtual machine server.
Meanwhile, for the access to the external network, the load balancer 2 is connected to the VM3 of the right virtual machine server through the network 2 and the switch, that is, the VM3 of the right virtual machine server is the virtual machine server that is to provide the access service. At the same time, VM3 in the right virtual machine server returns the access result to the client that initiated the access request.
Further, based on a preset load balancing algorithm, when a virtual machine server providing the access service is to be provided in the plurality of virtual machine servers, load information corresponding to the plurality of virtual machine servers is acquired. Wherein the load information includes at least one of: CPU utilization information and memory utilization information.
And then, determining the request type of the access request, and searching a load balancing model corresponding to the request type in a preset load balancing model database. That is, different request types correspond to different load balancing models. And finally, determining the virtual machine server to be provided with the access service according to the load balancing model and the load information.
Further, when determining the virtual machine server to be provided with the access service according to the load balancing model and the load information, the plurality of virtual machine servers are respectively ordered according to the load information to determine the priority level of each virtual machine server. And then, determining the virtual machine server to be provided with the access service according to the preset scheduling rule corresponding to the load balancing model and the priority level of the virtual machine server. Wherein, the higher the priority level, the smaller the load pressure of the virtual machine server. For example, a plurality of priority levels of a virtual machine server that is to provide an access service are first determined, and then concurrent traffic in an access parameter is divided into a plurality of sets of concurrent traffic corresponding to the plurality of priority levels, that is, one priority level corresponds to each set of concurrent traffic. Each set of concurrent traffic is then evenly distributed to the virtual machine servers of the same priority level.
In some embodiments of the present application, after the load balancing software to be started is started, an update access request that is re-uploaded by the user is obtained. Wherein the update access request includes update access parameters required by the user at the time of access. And then, according to the update access parameters, updating the load balancing software to be started, and generating an update configuration file corresponding to the updated load balancing software to be started. And then deleting the starting file, and adding the updating configuration file into the initial folder to obtain the updating starting file.
And finally, starting the updated load balancing software to be started according to the starting virtual network, the updated starting file and the process space. That is, when the user modifies the load balancing service required by the user, the content of the above steps is updated again according to the new parameters required by the user.
By adding the identifier to the load balancing software through the method of fig. 1, the capacity of the SDN controller for identifying a plurality of load balancing software, such as supporting a protocol, supporting concurrent traffic, and the like, can be realized, so that a plurality of load balancing software of the nano tube can be realized, and the load balancing software matched with the concurrent traffic of different orders and different communication protocols can be automatically selected in time to provide services, so that the nano tube efficiency is improved, and the performance waste of the load balancing software is avoided.
And based on the encapsulation isolation linux nasespace technology, the process, the configuration file and the network port of the newly started load balancing service on the network server are isolated in each nasespace, are isolated and invisible from each other, and cannot influence each other.
It should be noted that, although the embodiment of the present application is described with reference to fig. 1 for sequentially describing steps S102 to S114, this does not represent that steps S102 to S114 must be performed in strict sequence. The steps S102 to S114 are sequentially described according to the sequence shown in fig. 1 according to the embodiment of the present application, so as to facilitate the understanding of the technical solution of the embodiment of the present application by those skilled in the art. In other words, in the embodiment of the present application, the sequence between the steps S102 to S114 may be appropriately adjusted according to the actual needs.
Based on the same thought, some embodiments of the present application further provide an apparatus, a device, and a non-volatile computer storage medium corresponding to the above method.
