The technical solutions proposed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The network regulation and control method based on the SDN is applied to a network regulation and control system based on the SDN, the system comprises an SDN access management module, an SDN control module, an access end device and a network bearing device, and management Internet Protocols (IP) among all module devices of the system can reach each other.
Fig. 1 is a flowchart of a network regulation and control method based on an SDN according to an embodiment of the present application. As shown in fig. 1, a network regulation and control method based on an SDN provided in an embodiment of the present application mainly includes the following steps:
s101: and recording the first configuration information of the access terminal equipment into an SDN access management module so that the SDN access management module manages the access terminal equipment.
The server inputs a user name, a password, an IP address, a Simple Network Management Protocol (SNMP) and a Secure Shell Protocol (SSH) which are configured in advance by the access terminal equipment into the SDN access Management module, wherein the access terminal equipment refers to an access terminal switch or an access terminal wireless router. Based on the management network, the SDN access management module verifies the input IP address through the SNMP protocol and the SSH protocol, and if the access terminal equipment is successfully accessed according to the IP address, the SDN access management module successfully manages the access terminal equipment. The SDN access management module also acquires configuration information and state information of the access terminal equipment through an SNMP protocol and stores the configuration information and the state information to an SDN memory. The method and the device can manage the equipment through the module, so that flexible management of the network can be facilitated.
S102: and performing user registration based on the SDN access management module so as to bind a user using the access terminal equipment and a use terminal corresponding to the user.
The server performs user registration through a user registration function of the SDN access management module, so that registered users can acquire state information and configuration modification information of the switch in the network. The server determines a relevant interface which is in butt joint with third-party network management software or a wireless router plug-in through the SDN access management module, acquires terminal information used by a user through the relevant interface, and synchronizes user information to the SDN control module or management software used by the user through a user information interface. Meanwhile, the server binds the user using the access terminal device with the user terminal corresponding to the user, so as to perform network management on the user terminal under the user name.
In an embodiment of the present application, after the server binds the user using the access end device with the user terminal corresponding to the user, each user terminal using the access end device is monitored. The server determines a user corresponding to a new user terminal by monitoring and determining that the new user terminal uses the access terminal device, and simultaneously acquires the use time, the MAC address and the Internet protocol IP address of the new user terminal, and adds the use time, the MAC address and the Internet protocol IP address to a user name corresponding to the new user terminal so as to perform network management on the user terminal under the user name in the follow-up process.
In an embodiment of the application, after a server binds a user using an access terminal device with a user terminal corresponding to the user, the server controls the access terminal device to detect each user terminal at intervals of a first preset time period. The server enables the access terminal device to initiate ping operation to the on-line user terminal through an Interface or a corresponding device management Application Program Interface (API) or the like, so as to detect whether the user terminal is reachable. Wherein, the state of the user terminal using the access terminal device is defaulted to the online state. If the server determines that the response times of the user terminal are smaller than a preset threshold value, marking the state of the user terminal as an offline state, and synchronizing the offline state information to the SDN control module so that the SDN control module processes the user terminal. The preset threshold value can be determined according to actual conditions, and the preset threshold value is not limited in the application.
Specifically, the preset threshold value in the application is defaulted to 3 times, if the server determines that the used terminal is unreachable in a three-time period, the state of the used terminal is marked as an offline state, and the offline state information is synchronized to the SDN control module, so that the SDN control module changes the network configuration of the SDN control module. Therefore, the terminal which is not used for a long time can be offline, so that the network bandwidth corresponding to the used terminal is released, and the network load is optimized.
S103: and respectively carrying out priority marking and bandwidth configuration on each using terminal, and storing the priority marking and the bandwidth configuration into an SDN memory.
The server marks the priority of each user terminal through an SDN access management module, configures guaranteed bandwidth and suggested bandwidth for each user terminal, and stores the priority, guaranteed bandwidth and suggested bandwidth corresponding to each user terminal to an SDN memory.
For example, the priority flag ranges from 0 to 255, and the higher the number, the higher the priority of using the terminal. The default priority of the on-line using terminal is 1, the priority of the using terminal with guaranteed bandwidth is 255, the priority of the off-line using terminal is 0, and the off-line using terminal does not participate in the allocation of network bandwidth.
The guaranteed bandwidth refers to the lowest bandwidth for completing a certain service, and the server configures the guaranteed bandwidth for the terminal for performing the important service so as to ensure that the bandwidth of the important service is not affected. Meanwhile, the server also determines that the guaranteed bandwidth does not exceed the maximum bandwidth of the network, so that the rationality of the guaranteed bandwidth is ensured. On the basis of ensuring that the service of the using terminal with the guaranteed bandwidth parameter is not influenced, when the residual bandwidth is not enough to bear other services, the server can sequentially downwards adjust the network bandwidth corresponding to each using terminal according to the priority of each using terminal based on the suggested bandwidth of each using terminal.
S104: and inputting the second configuration information of the network bearing equipment into the SDN control module so that the SDN control module manages the network bearing equipment, and configuring a resource pool according to the scale and the number of the access terminal equipment and the network bearing equipment.
The server inputs a user name, a password, an IP address, an SNMP protocol and an SSH protocol which are configured in advance by the network bearing equipment into the SDN control module, wherein the network bearing equipment refers to a service network bearing exchanger or a service network bearing encryption card. Based on the management network, the SDN control module verifies the input IP address of the network bearing equipment through the SNMP protocol and the SSH protocol, and if the network bearing equipment is successfully accessed according to the IP address, the SDN control module successfully manages the network bearing equipment. And the SDN control module acquires the configuration information and the state information of the network bearing equipment through an SNMP protocol and stores the configuration information and the state information into an SDN memory. And the server also configures a resource pool according to the scale and the number of the access terminal equipment and the network bearing equipment for subsequent automatic management. According to the method and the system, the SDN control module realizes automatic network control according to the configuration information in the resource pool in a resource pool configuration mode, so that human resources are saved, and the cost of network control is reduced.
In one embodiment of the present application, the network scope of the resource pool is a VLAN scope, or VXLAN L2 and VXLAN L3 scope, and the resource pool includes a routing protocol resource pool, a service network resource pool, an alarm configuration resource pool, an NTP resource pool, and a user information resource pool.
The server configures routing protocols corresponding to the services through a routing protocol resource pool, the contents of the resource pool may be different among different routing protocols, and the routing protocol resource pool is mainly determined according to the routing protocol used by the data center; configuring a service address of network bearing equipment through a service network resource pool, and establishing a plurality of service network resource pools aiming at a multi-region management scene; configuring a reporting address of the alarm information of the access terminal equipment through an alarm configuration resource pool; the NTP service address of the SDN control module is configured through the NTP resource pool, so that the synchronous time of the switch is ensured; and configuring the name, the user name and the password of the network bearing equipment, supporting a login protocol and a simple network management protocol through the user information resource pool.
In addition, the server needs to take into account future scalability of the switch, such as increasing the device scaling. If the corresponding resource pool is configured only according to the requirements of the current equipment, the scale expansion of the switch at the later stage may exceed the range of the resource pool, so that the expansibility is considered when the resource pool is configured, and a larger resource pool is configured, so that the resource pool can have a redundant part.
S105: and based on the SDN control module, sending a corresponding communication protocol according to the protocol configuration parameters in the resource pool to complete the underlying network configuration of the nano-tube network bearing equipment.
The server automatically issues corresponding communication protocols, such as a border gateway protocol, an open shortest path first protocol and the like, according to relevant parameters of protocol configuration in the resource pool, so that the SDN control module completes the configuration of the underlying network of the nanotube network bearing equipment, and is convenient for bearing the service network of the upper layer.
In an embodiment of the application, the SDN control module and the SDN access management module both have an administrator and a user identity authority by default, and have an administrator authority account by default. The server may create an administrator or user account using an administrator authority account of the SDN control module or the SDN access management module and configure a user name and a login password for it. The server starts the binding permission of the SDN access management module by using an account with administrator authority at the SDN control module, or starts the binding permission of the SDN control module by using the account with administrator authority at the SDN access management module, and randomly generates a 16-bit access module binding password by using components such as an Open Secure Sockets Layer (OpenSSL). The server confirms the correctness of the binding password through the management network, if the verification is correct and the IP verification can be achieved, the binding is successful, the SDN access management module and the SDN control module are bound through the binding password, and the information after the binding is interacted through the management network.
In addition, after the generation time of the binding password exceeds a second preset time period, the binding password is invalid, and the server needs to regenerate the binding password corresponding to the binding module. The second preset time period in the present application is 24 hours, and the second preset time period may be determined according to an actual situation, which is not limited in the present application.
S106: and acquiring the priority of each using terminal in the SDN memory through the management network so as to adjust the network bandwidth of each using terminal according to the priority.
The server obtains the priority of each use terminal in the SDN memory through the management network, and enables the SDN control module to sequentially and downwards adjust the network bandwidth of each use terminal according to the priority according to the suggested bandwidth of each use terminal on the basis of ensuring that the service with guaranteed bandwidth parameters is not influenced, so that the network load is optimized.
In an embodiment of the application, after the SDN access management module and the SDN control module are bound by the server, in the SDN control module, the server acquires the configuration parameters in the resource pool and the attributes such as the priority of each user terminal through the management network, so as to randomly acquire different VXLAN identifiers from the network range of the resource pool according to the acquired information, and then creates different VXLAN networks for each user terminal on the network bearing device through an OpenFlow table or a corresponding control application program interface API manner, so that each user terminal accesses a specified service network, and the VXLAN networks used by each user terminal are ensured not to be repeated. The application ensures the independence of the terminal network through the VXLAN network.
In an embodiment of the present application, when the server creates a related service network on the network bearer device according to information of each user terminal, data sent by each user terminal is encrypted through a heterogeneous accelerator card deployed on the service network and a preset Advanced Encryption Standard (AES) Encryption algorithm, so as to ensure security of the service network.
In an embodiment of the present application, after the server marks the state of the user terminal as an offline state, in a case that it is detected that the user terminal in the offline state uses the access terminal device again, the server needs to verify that the MAC address of the user terminal in the current offline state is the MAC address of the user terminal corresponding to the user. And in the case of determining that the MAC addresses of the two are the same, marking the using terminal as an online state, and updating the access time of the using terminal. And meanwhile, the server synchronizes the information to the SDN control module so that the SDN control module randomly acquires a unique VXLAN identifier from the network range of the resource pool through a management network, and then creates a new VXLAN network for the user terminal on the network bearing equipment in an OpenFlow flow table or corresponding control Application Program Interface (API) mode, thereby ensuring that the networks used when the user terminal is accessed each time are different as much as possible.

As shown in fig. 2, the present application provides a network regulation and control method based on SDN, which is applied to a network regulation and control system based on SDN, and the system includes an SDN access management module, an SDN control module, an access device, and a network bearer device. The user terminal, the access terminal switch or the wireless router, the network bearing switch or the encryption card and the service terminal device in fig. 2 communicate with each other through the service network. The server manages an access terminal switch or a wireless router through the SDN access management module, and manages a network loading switch or an encryption card through the SDN control module.
