Detailed Description
In order to explain technical contents, achieved objects, and effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.
Referring to fig. 1 to 3, a method for real-time management and control of a terminal in a wide area network includes the steps of:
establishing one-way communication connection with a controlled terminal under a wide area network, and receiving a communication request sent by the controlled terminal;
if the communication request is an IPV6 communication request, acquiring and storing an IPV6 address in the IPV6 communication request;
when a management and control instruction is to be sent to a managed terminal, the management and control instruction is sent to the managed terminal through the IPV6 address.
From the above description, the beneficial effects of the present invention are: in a wide area network, when a controlled terminal supports IPV6 communication, an IPV6 address of the controlled terminal is obtained and stored, so that when a control server side sends a control instruction to the controlled terminal, the control instruction is sent to the controlled terminal through the IPV6 address, and the terminal responds in real time; meanwhile, the control server actively initiates control, resource waste of service performance caused by polling of the control server by the control terminal can be reduced, the IPV6 address is huge, and the control server can manage more terminals, so that the requirements of reducing resource waste and realizing real-time terminal control can be met under a wide area network.
Further, the receiving of the communication request sent by the regulated terminal is specifically receiving of the communication request sent by the regulated terminal through the IPV4 address.
From the above description, it can be known that the network environment supporting both IPV4 address and IPV6 address can provide management and control services continuously even when the network device is replaced excessively.
Further, after the communication mode corresponding to the communication request is judged, the communication mode supported by the managed and controlled terminal is recorded.
Further, storing the IPV6 address specifically includes: binding the IPV6 address with the terminal identification and then adding the binding into a communication address table;
when a management and control instruction is to be sent to a managed and controlled terminal, a communication mode supported by the managed and controlled terminal is firstly inquired, if the communication mode is IPV6 communication, the communication address table is inquired to obtain an IPV6 address of the managed and controlled terminal, and then the management and control instruction is sent to the managed and controlled terminal through the IPV6 address.
As can be seen from the above description, by recording the communication modes supported by the management and control terminal, and then when sending the management and control instruction, querying the communication modes supported by the management and control terminal, and then sending the management and control instruction correspondingly, the sending of the management and control instruction is faster and more accurate.
Further, still include:
receiving a new IPV6 address actively reported by a controlled terminal, and updating the communication address table; and/or
And issuing an address updating instruction to the managed terminal, and updating the communication address table if a new IPV6 address returned by the managed 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, a new IPV6 address must be reported to the management and control server, and in order to prevent the IPV6 address reported by the managed terminal from losing packets, the management and control server may request a new IPV6 address from the managed and control terminal, so as to ensure that the IPV6 address stored by the management and control server is valid and available.
Further, still include:
polling all IPV6 addresses in the communication address table, and stopping issuing a control instruction to a controlled terminal corresponding to a certain IPV6 address if the controlled terminal does not return response information.
As can be seen from the above description, by real-time polling of the management and control server, when the IPV6 address is valid and a new IPV6 address is not received, the response message returned by the managed terminal is not received, which indicates that the managed terminal has already downloaded, and therefore, the management and control instruction is stopped from being issued to the managed terminal, and resource waste of the management and control server is reduced.
Further, the sending the management and control instruction to the managed terminal through the IPV6 address specifically includes:
the management and control instruction is converted into an IPV6 protocol and then is sent to a managed terminal through the IPV6 address.
Further, if the communication request is a long connection request, after a long connection communication link is established with the controlled terminal, a control instruction is issued to the controlled 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 control instruction is to be sent to a controlled terminal, a communication mode supported by the controlled terminal is inquired first, if the communication mode is message communication, a unique message ID of the controlled terminal is inquired and obtained, the control instruction is packaged into a message instruction according to the unique message ID and then is issued to a message queue, and then the controlled terminal acquires and executes 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, the managed terminal may also be managed in real time by using a long connection manner or a message communication manner, so that the present solution may adapt to different network environment architectures, and a communication manner combining IPV4, IPV6, a message queue, and long connection is used to ensure that the management and control service end can manage and control terminal devices 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, and when the processor executes the computer program, the steps in the method for real-time management and control of the terminal in the wide area network are implemented.
From the above description, the beneficial effects of the present invention are: in a wide area network, when a controlled terminal supports IPV6 communication, an IPV6 address of the controlled terminal is obtained and stored, so that when a control server side sends a control instruction to the controlled terminal, the control instruction is sent to the controlled terminal through the IPV6 address, and the terminal responds in real time; meanwhile, the control server actively initiates control, resource waste of service performance caused by polling of the control server by the control terminal can be reduced, the IPV6 address is huge, and the control server can manage more terminals, so that the requirements of reducing resource waste and realizing real-time terminal control can be met under a wide area network.
