Description
Technical Field
The present invention relates to the field of network communication technologies, and in particular, to a configuration method and a configuration device for an OpenFlow virtual switch.
Background
The network based on the IP protocol can guarantee the most basic network connectivity, but when the service has a requirement other than the network connectivity, for example, when the route selection is performed based on the source address, the device needs to be implemented in a special manner, and different implementation schemes of different device manufacturers are different, which easily results in an increase in the user investment cost.
In this context, the OpenFlow technique has emerged. OpenFlow is a network communication protocol for controlling the data plane of a network switch. In recent years, with the rapid rise of cloud computing and virtualization, based on the programmable characteristics brought to the Network by the OpenFlow protocol, an SDN (Software Defined Network) appears, the core of which is to separately forward and manage, so that a traditional switch and a traditional router are only responsible for forwarding a packet, and forwarding policies and rules of the packet are managed by a centralized controller.
With the development and wide application of the SDN application, the number of OpenFlow-based SDN network switching devices is increasing. The controller communicates with the configured switch according to the OpenFlow protocol. The configuration of the switch needs to be completed before normal operation, and the configuration is beyond the scope of the OpenFlow protocol specification and needs to be completed through other configuration protocols. In order to configure and manage an OpenFlow switch, an OF-CONFIG configuration management protocol is proposed by an Open Network Foundation (ONF), which is a network management protocol for an OpenFlow switch.
In the existing virtual switch configuration method, the virtual switch can be configured by combining a YANG model and a NETCONF protocol. Among them, the YANG model is called YetAnother Next Generation model.
However, because the custom YANG model and the NETCONF protocol are used in the existing method and do not conform to the OF-CONFIG protocol specification, only basic configuration, such as adding/deleting a bridge and configuring an IP address OF a switch, can be performed in the process OF configuring the OpenFlow virtual switch, and thus the richer functions OF the OpenFlow virtual switch cannot be realized.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a configuration method for an OpenFlow virtual switch, where the configuration method may include the following steps:
s101, obtaining configuration data of parameters to be configured in the OpenFlow virtual switch to be configured.
In the embodiment of the present invention, the OpenFlow virtual switch to be configured refers to an OpenFlow virtual switch that is not configured yet, and in an SDN network environment, if a function of the virtual switch is to be implemented, the virtual switch needs to be configured. The OpenFlow virtual switch refers to a virtual switch operating based on an OpenFlow network communication protocol, for example, an ovs (open vswitch) virtual switch.
The OpenFlow virtual switch may be configured by a configuration parameter, for example, the virtual switch may be named by a configuration parameter of virtual-switch-id (local-switches-id). Of course, the above example is only one of the configuration parameters of the OpenFlow virtual switch. It is easy to understand that when a configuration parameter is not set, it can be called a parameter to be configured. Generally, the configuration data of the parameters to be configured may be set manually, so that the server may obtain the configuration data of the parameters to be configured.
As an optional implementation manner of the embodiment of the present invention, the configuration method of the OpenFlow virtual switch according to the embodiment of the present invention may be implemented based on a B/S (Browser/Server) architecture, that is, a setting interface is displayed in a Browser of a user end device, where the setting interface shows each parameter to be configured in the OpenFlow virtual switch, and a user may complete configuration parameter setting by inputting configuration data, for example, in a local-switches-id option of the parameter to be configured, the user inputs a name switch 1 of the virtual switch, and thus may complete setting of an id of the virtual switch. Then, the configuration data is transmitted to the server through the network, and the server acquires the configuration data input by the user. The configuration data typically includes simple english, letters, and numbers.
And S102, generating a configuration file by using the acquired configuration data of the parameters to be configured.
After the server obtains the configuration data of the parameters to be configured, a configuration file can be generated, and various configuration parameters of the OpenFlow virtual switch to be configured are recorded in the configuration file.
As an optional implementation manner OF the embodiment OF the present invention, the format OF the generated configuration file may be an XML (Extensible Markup Language) format, which is a simple data storage Language, and is widely applied to the fields OF data storage and data transmission, and may be used to describe a data structure OF a NETCONF or OF-CONFIG protocol. As can be seen from the foregoing, since the configuration data usually contains simple english, letters, and numbers, the configuration data can be easily written into the configuration file in the XML format.
And S103, sending the configuration file to the OpenFlow virtual switch to be configured so that the OpenFlow virtual switch to be configured is configured according to the configuration file.
As shown in fig. 2, which is a system architecture diagram according to an embodiment of the present invention, a server may be connected to multiple client devices, and the server may also be connected to multiple OpenFlow virtual switches to be configured, so as to send a configuration file to the OpenFlow virtual switches to be configured.
After receiving the configuration file, the OpenFlow virtual switch to be configured can analyze configuration data OF each configuration parameter in the configuration file, and configure by using the configuration data, so that each function OF the OpenFlow virtual switch is realized.
The specific configuration process may be that the server connects to the OpenFlow virtual switch using a connect command; the server sends the xml-type configuration file to the OpenFlow virtual switch through an edge-config command to complete corresponding configuration; after configuration is complete, the server disconnects using a disconnect command.
As an optional implementation manner of the embodiment of the present invention, before step S103, the server may be connected to the host where the OpenFlow virtual switch is located in an SSH (Secure Shell, Secure Shell protocol) public key password-free authentication manner, so that a password may not be input in a subsequent automatic configuration.
As can be seen from the above, different configuration parameters may implement different functions of the OpenFlow virtual switch, where the functions at least include: logical switch management functions, port management functions, controller management functions, and switch setup backup functions. Also, these functions may include multiple sub-functions.
The logical switch management function in the embodiment of the present invention may include: the logical switch creates a sub-function, the logical switch modifies the sub-function, and the logical switch removes the sub-function.
Each sub-work may correspond to a plurality of configuration parameters, and the configuration parameters may be further divided into required configuration parameters and non-required configuration parameters. The required configuration parameters are parameters which are required to be used when the OpenFlow virtual switch is configured, and lack of the required configuration parameters may cause unsuccessful configuration of the OpenFlow virtual switch; the non-essential configuration parameters refer to parameters which are not essential when the OpenFlow virtual switch is configured, and the absence of the non-essential configuration parameters does not cause the configuration of the OpenFlow virtual switch to be unsuccessful.

In addition, according to the embodiment of the invention, the configuration file can be automatically generated according to the acquired configuration data, so that the convenience in configuration of the OpenFlow virtual switch is improved.
An embodiment of the present invention further provides a configuration method for an OpenFlow virtual switch, and as shown in fig. 3, the configuration method may include the following steps:
s201, obtaining configuration data of parameters to be configured in the OpenFlow virtual switch to be configured.
S202, generating a configuration file by using the acquired configuration data of the parameters to be configured.
And S203, sending the configuration file to the OpenFlow virtual switch to be configured so that the OpenFlow virtual switch to be configured is configured according to the configuration file.
