In this embodiment, referring to fig. 4, fig. 4 is a flowchart of a management-side problem solving process of a first embodiment of a network communication system in a limited environment of the present invention, breaking through network limitation and communication with a diagnostic server, and attempting network limitation problem solving again includes: a self-developed dynamic address acquisition protocol (Dynamic Address Acquisition Protocol) is used to acquire specific, temporary network address resources that can communicate with the diagnostic server, and the network address of the diagnostic server. Which can avoid paying attention to the validity of the current network configuration and address of the device. The dynamic address acquisition protocol comprises the following procedures and processes:
the system enables a network card promiscuous mode for the user equipment so that the user equipment can capture data packets in the local area network.
The diagnostic server (i.e., the diagnostic server module) maintains a pool of addresses that record valid borrowable network addresses that can be assigned to the user device.
Server broadcast mode: the server periodically broadcasts encrypted data with a specific identification, the data containing available address information in the address pool.
User self-discovery mode: and periodically transmitting the specific identification format data to the diagnosis server by the preset network equipment in the local area network where the system is located.
The system captures a data packet of a specific identifier of a server broadcast mode on user equipment through a network card, decrypts and selects a temporary available address and a diagnosis server address; or capturing and searching the preset network equipment with the specific identification by using the self-discovery mode of the user, and acquiring the address of the preset network equipment and the address of the opposite-end diagnosis server.
It should also be appreciated that the available network address resources are temporary network address resources.
In a further technical scheme, the server side comprises a diagnosis server module, the user equipment information is subjected to data encapsulation by using an Ethernet protocol based on IP/UDP and a self-defined data encapsulation technology, and the data encapsulation is sent to the diagnosis server through a network card to inform the system that the user equipment temporarily occupies a network address. The method comprises the following steps:
packaging data: and packaging the acquired relevant information of the equipment network environment according to a contracted protocol format.
Constructing a message: according to the customized encapsulation format, a buffer is created in the memory, and the encapsulated data is filled into the payload position of UDP according to the format.
Setting source and destination addresses: setting a source IP address as a temporary network address acquired by a dynamic address acquisition protocol in the previous process in the message, and setting a destination IP address as a network address of a diagnosis server.
Setting source and destination ports: source and destination port numbers are set in the message to identify the sender and receiver applications or services, these ports being agreed upon fixed ports.
And (3) sending a message: and calculating the filling checksum, and sending the constructed UDP message through the network card.
The diagnostic server receives: and receiving the UDP message through the designated port at the diagnosis server, analyzing, decrypting and judging the UDP message, acquiring the data of the user terminal, and using the address of the opposite terminal of the message when replying the data.
The diagnostic server marks that the network address used by the user has been occupied: and (3) setting the address unavailable state in the address pool or informing a preset network device in the local area network to stop sending the specific identification format data to the diagnosis server.
The proxy module (i.e., network proxy service) forwards the user traffic to provide proxy services for the user if it is subsequently required to provide normal network communication functions under temporary network constraints.
User equipment side data receiving: and capturing flow under the mixed mode network card, screening out a temporary network address with a destination address being the one obtained by the dynamic address obtaining protocol in the previous process, and obtaining data replied by the blocking server based on data analysis and extraction of the data encapsulation format, wherein the source address is a message of the network address of the diagnostic server.
The device network card is communicated with the diagnosis server through the effective address, and can establish communication with the diagnosis server in the available state of the device network card hardware, and the purpose of the communication is to report the identity information and the device network environment in the steps. This action is intended to inform the diagnostic server of more detailed device access information. The diagnostic server is typically deployed at a gateway or at a device node having network management rights.
It should be further noted that, breaking through the network limitation and communicating with the diagnostic server, attempting the network limitation problem again includes: determining network-limited problem attribution, the system has attempted to resolve the problem at the home device side at the user device side. At this time, the diagnosis server determines whether the problem belongs to the network management end, and if the diagnosis server can solve the problem, the diagnosis server solves the problem at the network management end. The technical scheme aims to solve the problem that active management is needed when new authorized equipment accesses to the network, the problem is attributed to the equipment network limitation condition caused by the management equipment limitation of a gateway, a route and the like, and the system detects as follows: configuring a static address binding network environment, and distributing new IP or adding static binding; in the network environment authorized to access, opening the network and unblocking; in a network environment requiring passive starting of DHCP, temporarily starting a DHCP service; routing table, routing policy, network address translation, firewall configuration errors; IP address conflict, DNS service configuration error, network congestion detection correction.
The server 2002 is configured to perform exception handling on the to-be-accessed ue according to a management-side network limitation detection result, and if the handling fails, enable the ue to perform network communication through a network proxy service provided by the network communication module.
Further, the server side comprises a diagnosis server module; the diagnosis server module performs exception processing on the user equipment to be accessed according to the network limited detection result of the management side, if the processing fails, the equipment end starts the network proxy service provided by the network communication module, and the open proxy port is used for receiving access request data; the service end obtains the access request data through the temporary network address and the proxy port based on the network proxy service provided by the network communication module, and performs network access according to the access request data.
In this embodiment, referring to fig. 5, fig. 5 is a temporary communication flow chart of a first embodiment of a network communication system in a limited environment of the present invention, temporarily providing normal network communication in a limited network includes: access device permission determination provides temporary available network access to devices that are compliant and in need of temporary communication. It is no longer concerned with the validity or otherwise of the current network address and configuration of the device and the system will allow the user device to temporarily use the temporary network address acquired by the previous dynamic address acquisition protocol, but this address is not visible to the user. The address, in addition to being used to communicate with the diagnostic server, will begin using the temporary available address at the detection and proxy module on the user device and provide a 9876 proxy port for the user device. All data forwarded to the port are sent to the diagnosis server in a packaged mode, at the moment, the network proxy service of the network communication module starts to work, the corresponding network request is accessed by a user instead, and the data are forwarded to provide proxy service for equipment.
The user may optionally set a system agent for the device or set a communication software agent port. All traffic forwarded to the proxy port will be sent to the destination and all returned traffic will be forwarded through the port to the corresponding user software without the need for proxy server setup in the traditional sense. In a further technical scheme, in the temporary equipment network access, the diagnosis server can carry out unexpected access restriction, and the purpose of management and restriction is to be carried out when the temporary equipment exceeds a limit, illegal access and traffic overrun.
Further, when the user equipment to be accessed temporarily does not meet the network access condition, the server binds the temporary network address as the long-acting network address with the user equipment to be accessed.
Referring to fig. 6, fig. 6 is a long-acting communication flow chart of the first embodiment of the network communication system in the limited environment of the present invention, and when it is determined that the network limitation is not resolved or a special problem (a problem on the device side and a problem on the management side) cannot be resolved, and when the device needs to be accessed and temporary access does not meet the requirements and settings, the device side detection and proxy module (i.e. network proxy service) will negotiate with the diagnostic server to provide a fixed proxy service for the device. The difference from the temporary proxy access is that in the distribution of the preset address resources by the diagnostic server, the address resources (i.e. temporary network addresses) will be transferred to a used state and bound with the corresponding device. For the actual problematic network environment of the device, the system will not attempt to solve any more, and through recording reporting, the subsequent solution and repair will be investigated and solved again by the corresponding network manager. During which the detection and proxy software provides a stable and reliable network communication service for the device. The diagnostic server will also determine the device identity again, which is the last procedure of the authentication scheme in this step.
Through two kinds of network-limited repair and two kinds of agents for providing normal communication under further network limitation, the embodiment still provides a usable communication scheme for the device even if the system cannot repair the network finally.
