Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present invention in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1 to 3, a method for real-time terminal management and control under a wide area network includes the steps of:
Establishing unidirectional communication connection with a managed terminal under a wide area network, and receiving a communication request sent by the managed terminal;
If the communication request is an IPV6 communication request, acquiring and storing an IPV6 address in the IPV6 communication request;
and when a management and control instruction is to be sent to the managed and controlled terminal, the management and control instruction is sent to the managed and controlled terminal through the IPV6 address.
From the above description, the beneficial effects of the invention are as follows: under the wide area network, when the managed terminal supports IPV6 communication, the IPV6 address of the managed terminal is obtained and stored, so that when the management and control server side is to send a management and control instruction to the managed terminal, the management and control instruction is sent to the managed terminal through the IPV6 address, and the terminal responds in real time; meanwhile, the management and control server actively initiates control, so that resource waste of service performance caused by polling of the management and control server by the managed and control terminal can be reduced, the IPV6 address is huge, and the management and control server can manage more terminals, so that the requirements of reducing resource waste and realizing real-time management and control of the terminals can be met simultaneously under a wide area network.
Further, the receiving of the communication request sent by the managed terminal is specifically receiving the communication request sent by the managed terminal through the IPV4 address.
From the above description, it can be seen that the network environment supporting both IPV4 addresses and IPV6 addresses can provide control services continuously even when the network device is replaced excessively.
Further, after judging the communication mode corresponding to the communication request, recording the communication mode supported by the managed terminal.
Further, storing the IPV6 address specifically includes: binding the IPV6 address with the terminal identifier and then adding a communication address table;
When a management and control instruction is to be sent to a managed and controlled terminal, firstly inquiring a communication mode supported by the managed and controlled terminal, if the communication mode is IPV6 communication, inquiring the communication address table to obtain an IPV6 address of the managed and controlled terminal, and then sending the management and control instruction to the managed and controlled terminal through the IPV6 address.
From the above description, it can be known that by recording the communication mode supported by the controlled terminal, and then when the control instruction is sent, firstly querying the communication mode supported by the controlled terminal, and then correspondingly sending the control instruction, the sending of the control instruction is faster and more accurate.
Further, the method further comprises the following steps:
receiving a new IPV6 address actively reported by a managed and controlled terminal, and updating the communication address table; and/or
And sending an address updating instruction to the managed and controlled terminal, and updating the communication address table if a new IPV6 address returned by the managed and controlled terminal is received.
As can be seen from the above description, since the IPV6 address is temporary, when the IPV6 address of the managed terminal changes, the new IPV6 address must be reported to the management server, so that, in order to prevent the packet loss phenomenon of the IPV6 address reported by the managed terminal, the management server may request the new IPV6 address to the managed terminal, so as to ensure that the IPV6 address stored by the management server is effectively available.
Further, the method further comprises the following steps:
And polling all IPV6 addresses in the communication address table, and stopping issuing a management and control instruction to the managed and controlled terminal if the managed and controlled terminal corresponding to a certain IPV6 address does not return response information.
According to the description, through real-time polling of the management and control server, when the new IPV6 address is not received and the effective period of the IPV6 address is not received, the response information returned by the managed and control terminal is not received, so that the managed and control terminal is indicated to have downloaded, and therefore, the management and control instruction is stopped from being issued to the managed and control terminal, and resource waste of the management and control server is reduced.
Further, the sending the control instruction to the controlled terminal through the IPV6 address specifically includes:
And converting the management and control instruction into an IPV6 protocol and then sending the IPV6 protocol to a managed terminal through the IPV6 address.
Further, if the communication request is a long connection request, after establishing a long connection communication link with the managed terminal, issuing a management and control instruction to the managed terminal based on the long connection communication link.
Further, if the communication request is a message communication request, receiving and storing a unique message ID in the message communication request;
When a management and control instruction is to be sent to a managed and controlled terminal, firstly inquiring a communication mode supported by the managed and controlled terminal, and if the communication mode is message communication, inquiring to obtain a unique message ID of the managed and controlled terminal, packaging the management and control instruction into a message instruction according to the unique message ID, and then issuing the message instruction to a message queue, so that the managed and controlled terminal can acquire and execute the message instruction according to the unique message ID after subscribing the message queue.
From the above description, when the managed terminal does not support IPV6 communication, a long connection manner or a message communication manner may also be used to perform real-time management and control on the managed terminal, so that the scheme may adapt to different network environment frameworks, and a communication manner combining IPV4, IPV6, a message queue, and long connection is used to ensure that the management and control server can manage and control the terminal device in real time.
Referring to fig. 4, the management and control server includes a memory, a processor, and a computer program stored in the memory and capable of running on the processor, where the processor implements the steps in the above-mentioned method for real-time terminal management and control under the wide area network when executing the computer program.
