As shown in fig. 2, the present invention aims to provide a new solution for implementing a network scenario that a device (such as an AP, a camera, a switch, a NAS, etc.) does not support remote access but needs to be remotely accessed by adding an access agent to a router device that has been accessed remotely, directly accessing a web interface of an intranet device and an upper device thereof through the remote agent, without supporting the remote access function for a remote web server that is reachable by a router.
The invention relates to a remote access system, which is characterized in that from the perspective of a remote architecture, the whole remote access system consists of a first network device supporting remote web access, a plurality of target devices which are connected with the first network device and do not support remote access, a cloud server for device management and a remote access terminal for remote access, wherein the four parts together complete remote access, the first network device, the plurality of target devices connected with the first network device and the first network device thereof are all arranged in a local area network 2, a remote access terminal of a user A is arranged in another local area network 1, and the user A realizes the access of the target devices which do not support remote access function in the local area network 2 through the cloud server. The treatment process of the invention is as follows:
1. the first network device (in this example, a router) at the device end of the local area network 2 obtains the information of the device of the object (in this example, AP device, camera, NAS server, intranet web server, etc.) hung below the first network device (in this example, a switch) through the second network device (in this example, a switch) of the embedded client, and adds the information of the corresponding protocol and port, etc. at the super remote interface, so that the access can be directly jumped through the jump link.
2. And the cloud server forwards the request to the equipment which is accessed to the cloud service and corresponds to the equipment according to the link ID of the request.
3. After the router equipment receives the request, the configuration information of the corresponding equipment is found according to the ID information, and the information of the equipment is used for initiating an agent request to realize remote access agent.
The second network device in this example also belongs to the destination device, and the function of the second network device switch is mainly to expand the functions of port/POE power supply, so as to implement the connection and remote communication functions of the multi-terminal device, and it may also apply for the address of the local area network, where the local area network address is uniformly distributed by the router.
The first network device in this example is used for establishing connection with the cloud server, so that the first network device is not limited to being placed at an outlet and can be used for proxy, and is nested in a multi-layer local area network, and the first network device can also be used for proxy.
If the router is placed in a nested local area network, the router is the first superior device of the destination device relative to the destination device, the address of the destination device is distributed by the router device of the proxy, and the proxy router forwards the address to the destination device when the remote access is received.
As shown in fig. 3, in the remote access process of the present invention, the first network device (which may be a gateway or an exchange) with the capability of the super remote proxy is a bridge connecting the user and the intranet destination device, and through the super remote proxy of the device, the user forwards the remote access of the intranet device of the device, and returns the data returned by the intranet device to the access user, so that the user achieves the same effect as the web server of the access device of the local area network, and does not need any modification and change of the intranet device. Specifically, the method for providing remote access for the equipment which does not support the remote access service comprises the following steps:
s1: and adding destination device information which is connected with the first network device and is to realize remote access through a super remote proxy function.
The destination device information in this example includes information such as protocol, port, and IP address, where the IP address may be manually IP or automatically matched from a DHCP list via a MAC address.
The newly added remote access device configuration interface and the added super remote interface are respectively shown in fig. 4 and fig. 5, and the newly added remote access device configuration interface of the present example supports the user to configure http/https protocol, supports the user to configure the custom port number when the server port is custom, supports the DHCP list IP synchronization through the MAC address, and also supports the manual IP address.
S2: after the addition is successful, the first network equipment generates a unique identification code for the target equipment in the local area network, and then the unique identification code is spliced with the remote access link of the first network equipment to generate a unique access link corresponding to the target equipment;
s3: after the first network device receives the access request of the cloud server, analyzing whether the access link has a unique identification field, if so, executing a step S4, and if not, accessing the first network device;
s4: searching whether corresponding configuration information exists or not according to the analyzed unique identification code field, if so, replacing a request head corresponding to the target equipment according to the configuration information, and initiating a proxy request to the target equipment in the local area network;
s5: and after receiving the response returned by the target equipment, the first network equipment replaces the response head of the target equipment with the related information of the original access request and returns the information to the cloud server.
In step S2 of this example, the unique identification code is an ID prefix, after generating the ID prefix corresponding to the destination device, the first network device generates a jump link to a display operation interface of the remote access terminal, and after the remote access terminal obtains the jump operation of the user, the remote access terminal sends the remote access request to the cloud server.
When a user clicks a jump link of a remote access terminal, the operation flow of the jump link is almost similar to that of the first network device which directly operates, after the cloud server receives the remote access request, the first network device which is correspondingly accessed to the cloud server is found by matching a link ID field, the request link is filled in a host field which is forwarded to a router request head, and the jump link is forwarded to the first network device through a tunnel established between the first network device and the cloud server.
After the first network device takes the data, if the ID of the destination device does not exist, the first network device is described as accessing the first network device, if the ID of the destination device is carried, the first network device is described as needing to be forwarded to the local area network destination device corresponding to the ID, therefore, the first network device replaces a request head according to the configuration information, and then the modified access request is forwarded to the corresponding destination device.
After the method and the device are used, all devices are not required to be connected with the server, only one connection is required to be established by the proxy device, and the resource occupation of the cloud server is reduced.
The above embodiments are preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, which includes but is not limited to the embodiments, and equivalent modifications according to the present invention are within the scope of the present invention.
