[0020] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, and various details of the embodiments of the present disclosure are included to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and mechanisms are omitted in the following description.

[0021] Figure 1 Schematic diagram of the first embodiment of the present disclosure. Figure 1 As shown, the method for providing HTTP services in this embodiment is applied to a full-cone edge sub-device and specifically includes the following steps:

[0022] S101. Sending a registration request to a detection keepalive server through a Transmission Control Protocol (TCP) socket in client mode established on a target port, wherein the registration request is used to register the full-cone edge sub-device in the detection keepalive server;

[0023] S102: After receiving the registration response message sent by the detection keep-alive server through the TCP socket in the client mode, establish a TCP socket in the server mode on the target port;

[0024] S103: After receiving a first keep-alive message regularly sent by the detection keep-alive server through the TCP socket in the server mode, extracting a public network address from the first keep-alive message;

[0025] S104: Register the HTTP service provided by the full-cone edge sub-device according to the public network address, so that the client accesses the full-cone edge sub-device through the public network address to use the HTTP service.

[0026] The executor of the method for providing HTTP service in this embodiment is a full cone edge sub-device. The full cone edge sub-device adopts the method of establishing a TCP socket in client mode and a TCP socket in server mode on a target port respectively, so as to achieve the purpose of obtaining its own public network address by detecting the keep-alive server and then providing HTTP service. The full cone edge sub-device connects to the client and transmits data based on the TCP protocol, thereby improving the success rate of establishing a connection between the full cone edge sub-device and the client and enhancing the stability of data transmission between the full cone edge sub-device and the client.

[0027] The full-cone edge sub-device in this embodiment may also be referred to as a NAT1 edge sub-device, which is one of four NAT (Network Address Translation) types. The full-cone edge sub-device in this embodiment may be a server from a third-party manufacturer.

[0028] In this embodiment, the full-cone edge sub-device executes S101 to send a registration request to the detection keep-alive server, which may also include identification information of the full-cone edge sub-device. The identification information may be a device ID, a device name, and the like.

[0029] Therefore, the detection keep-alive server of this embodiment registers the full-cone edge sub-device, that is, the detection keep-alive server records the correspondence between different edge sub-devices and different identification information.

[0030] When the full-cone edge sub-device of this embodiment executes S101 to send a registration request to the detection keep-alive server through the client mode TCP socket, it can first send the registration request to the edge master device (such as an edge gateway, edge router, etc.) through the client mode TCP socket established on the target port, and then the edge master device forwards the registration request to the detection keep-alive server; wherein, the edge master device is connected to at least one edge sub-device, and the edge master device can determine the public network address of each edge sub-device connected to it.

[0031] In this embodiment, when the edge master device forwards the registration request sent by the full-cone edge sub-device to the detection keep-alive server, it can also determine the public network address of the full-cone edge sub-device, add the public network address to the registration request, and then send the registration request to the detection keep-alive server.

[0032] After executing S101, the full-cone edge sub-device of this embodiment sends a registration request to the detection keep-alive server through the client mode TCP socket established on the target port, and executes S102, after receiving the registration response message sent by the detection keep-alive server through the client mode TCP socket, to establish a server mode TCP socket on the target port.

[0033] When the full-cone edge sub-device of this embodiment executes S102, if it receives a registration response message sent by the detection keep-alive server, it indicates that the detection keep-alive server has completed the registration of the full-cone edge sub-device; if the full-cone edge sub-device does not receive a registration response message within a period of time, it indicates that the registration is unsuccessful, and it can send a registration request to the detection keep-alive server again, and repeat this cycle until it receives a registration response message or the number of registration requests sent reaches a preset number.

[0034] When executing S102, the full-cone edge sub-device of this embodiment can receive the registration response message forwarded by the edge master device through the client mode TCP socket established on the target port; and the registration response message forwarded by the edge master device is sent to the edge master device after the detection keep-alive server completes the registration of the full-cone edge sub-device. The detection keep-alive server can add the public network address of the full-cone edge sub-device to the registration response message, so that the edge master device can accurately forward the registration response message according to the public network address in the registration response message.

[0035] After executing S102 and receiving the registration response message, the full-cone edge sub-device of this embodiment establishes a server mode TCP socket on the target port of the client mode TCP socket; the server mode TCP socket can communicate directly with the detection keep-alive server or client without going through the edge main device.

[0036] After executing S102 and receiving the registration response message sent by the detection keep-alive server, the full-cone edge sub-device of this embodiment may further execute the following: closing the client mode TCP socket established on the target port.

[0037] After executing S102 to establish a TCP socket in server mode on the target port, the full-cone edge sub-device of this embodiment executes S103 to extract the public network address from the first keep-alive message after receiving the first keep-alive message sent periodically by the detection keep-alive server through the TCP socket in server mode.

[0038] That is to say, the detection keep-alive server of this embodiment will continuously send the first keep-alive message to the full-cone edge sub-device at a certain time interval. If the full-cone edge sub-device can receive the first keep-alive message, it indicates that the full-cone edge sub-device can be accessed through TCP or HTTP, that is, it can provide HTTP service; if the full-cone edge sub-device does not receive the first keep-alive message, it indicates that the full-cone edge sub-device cannot provide HTTP service.

[0039] After executing S103 to extract the public network address from the first keep-alive message, the full-cone edge sub-device of this embodiment executes S104 to register with the HTTP service provided by the full-cone edge sub-device according to the public network address, so that the client can access the full-cone edge sub-device through the public network address to use the HTTP service.

[0040] The HTTP service in this embodiment is a service based on HTTP requests, such as a network disk service, a web page service, etc. Data can be stored and downloaded through the network disk service, and web pages can be browsed through the web page service.

[0041] When the full-cone edge sub-device of this embodiment executes S104 to register according to the public network address and the HTTP service provided by the full-cone edge sub-device, it can register in the domain name server or the address server, so that the correspondence between the public network address of the full-cone edge sub-device and the HTTP service provided by the full-cone edge sub-device is recorded in the domain name server or the address server.

[0042] After completing the registration of the public network address and HTTP service of the full-cone edge sub-device, the relevant client can query in the domain name server or address server according to the HTTP service to be used, and then access the corresponding full-cone edge sub-device according to the public network address obtained by the query. Specifically, it communicates with the TCP socket of the server mode of the full-cone edge sub-device based on the public network address, so as to perform related operations such as data storage or downloading, or browsing web pages.

[0043] Figure 2 Schematic diagram of the second embodiment of the present disclosure. Figure 2 As shown in , the method for providing HTTP services in this embodiment may further include the following contents:

[0044] S201, detecting whether the TCP socket in the client mode is closed;

[0045] S202. When it is determined that the TCP socket in the client mode is not closed, a second keep-alive message is periodically sent to the detection keep-alive server through the TCP socket in the client mode, so that the detection keep-alive server can register with the HTTP service provided by the full-cone edge sub-device according to the public network address of the full-cone edge sub-device after receiving the second keep-alive message periodically sent by the full-cone edge sub-device.

[0046] That is to say, the full-cone edge sub-device of this embodiment can also continuously send a second keep-alive message to the detection keep-alive server through the TCP socket at a certain time interval without closing the TCP socket in client mode, so that the detection keep-alive server can know that the full-cone edge sub-device is in a survival state, and then the detection keep-alive server executes the registration of the public network address and its corresponding HTTP service, which can improve registration efficiency.

[0047] When the full-cone edge sub-device of this embodiment executes S202 to periodically send the second keep-alive message to the detection keep-alive server through the TCP socket in client mode, it can first send the second keep-alive message to the edge master device through the TCP socket in client mode, and then the edge master device forwards the second keep-alive message to the detection keep-alive server.

[0048] Figure 3 Schematic diagram of the third embodiment of the present disclosure. Figure 3 As shown, the method for providing HTTP service in this embodiment is applied to detect a keep-alive server and specifically includes the following steps:

[0049] S301: After receiving a registration request sent by a Full Cone Edge sub-device, register the Full Cone Edge sub-device, where the registration request is sent by the Full Cone Edge sub-device through a TCP socket in client mode established on a target port;

[0050] S302: Generate a registration response message and send it to the Full-Cone Edge sub-device, where the registration response message is used by the Full-Cone Edge sub-device to establish a TCP socket in server mode on a target port.

[0051] S303: Periodically send a first keep-alive message to the full-cone edge sub-device, and the full-cone edge sub-device receives the first keep-alive message through the TCP socket in server mode, wherein the first keep-alive message includes the public network address corresponding to the full-cone edge sub-device.

[0052] The execution body of the method for providing HTTP service in this embodiment is located in the detection keep-alive server, which can support the reception and sending of TCP protocol messages. Through the interaction between the detection keep-alive server and the full-cone edge sub-device, the full-cone edge sub-device can obtain the public network address and then provide HTTP service.

[0053] When executing S301, the detection keep-alive server of this embodiment can obtain a registration request forwarded by the edge master device corresponding to the full-cone edge sub-device, and the registration request includes the identification information of the full-cone edge sub-device; when registering the full-cone edge sub-device, the detection keep-alive server of this embodiment specifically records the correspondence between the full-cone edge sub-device and the identification information.

[0054] After executing S301 to register the full-cone edge sub-device, the detection keep-alive server of this embodiment can also extract the public network address corresponding to the full-cone edge sub-device from the registration request. The public network address is added when the edge master device corresponding to the full-cone edge sub-device forwards the registration request to the detection keep-alive server.

[0055] After executing S301 to register the full-cone edge sub-device, the detection keep-alive server of this embodiment executes S302 to generate a registration response message and sends it to the full-cone edge sub-device.

[0056] It is understandable that, when executing S302 to generate the registration response message, the detection keep-alive server of this embodiment may also obtain the public network address corresponding to the full-cone edge sub-device, and then add the public network address to the registration response message.

[0057] When executing S302 to send the registration response message to the full-cone edge sub-device, the detection keep-alive server of this embodiment can first send the registration response message to the edge master device, and then the edge master device forwards the registration response message to the full-cone edge sub-device through the TCP socket in client mode.

[0058] After executing S302 to generate a registration response message and send it to the full-cone edge sub-device, the detection keep-alive server of this embodiment executes S303 to periodically send a first keep-alive message to the full-cone edge sub-device.

[0059] When executing S303 to periodically send the first keep-alive message to the full-cone edge sub-device, the detection keep-alive server of this embodiment can periodically send the first keep-alive message to the full-cone edge sub-device according to the public network address corresponding to the full-cone edge sub-device; wherein the first keep-alive message includes the public network address of the full-cone edge sub-device.

[0060] After executing S303 to periodically send the first keep-alive message to the full-cone edge sub-device, the detection keep-alive server of this embodiment may also include the following content: after receiving the second keep-alive message periodically sent by the full-cone edge sub-device, register with the HTTP service provided by the full-cone edge sub-device according to the public network address.

[0061] The second keep-alive message received by the detection keep-alive server of this embodiment is sent by the full-cone edge sub-device through the TCP socket in client mode; similarly, the detection keep-alive server can obtain the second keep-alive message forwarded by the edge master device.

[0062] Figure 4 is a schematic diagram according to a fourth embodiment of the present disclosure. Figure 4FIG4 shows an interaction diagram between the full-cone edge sub-device, the detection keep-alive server, the domain name or address server, and the client when providing HTTP service in this embodiment: S401, the full-cone edge sub-device establishes a TCP socket in client mode on the target port; S402, the full-cone edge sub-device sends a registration request to the registration keep-alive server through the TCP socket in client mode; S403, the detection keep-alive server registers the full-cone edge sub-device according to the registration request, and records the public network address of the full-cone edge sub-device; S404, the detection keep-alive server sends a registration response message to the full-cone edge sub-device, and the full-cone edge sub-device receives the registration response message through the TCP socket in client mode; S405, after receiving the registration response message, the full-cone edge sub-device closes the TCP socket in client mode and establishes a TCP socket in server mode on the target port; S406 6. The detection keep-alive server periodically sends the first keep-alive message to the full-cone edge sub-device, and the first keep-alive message includes the public network address corresponding to the full-cone edge sub-device; S407. After receiving the first keep-alive message sent by the detection keep-alive server through the TCP socket in server mode, the full-cone edge sub-device extracts the public network address from the first keep-alive message; S408. The full-cone edge sub-device registers in the domain name or address server according to the public network address and the HTTP service it provides; S409. The domain name or address server records the correspondence between the public network address of the full-cone edge sub-device and the HTTP service it provides; S410. The client accesses the domain name or address server to query the public network address corresponding to the HTTP service it needs; S411. The client accesses the full-cone edge sub-device according to the public network address obtained from the query to use the HTTP service provided by the full-cone edge sub-device.

[0063] Figure 5 Schematic diagram of the fifth embodiment of the present disclosure. Figure 5 As shown, the apparatus 500 for providing HTTP services in this embodiment is applied to a full-cone edge sub-device, including:

[0064] The first sending unit 501 is configured to send a registration request to a detection keepalive server through a Transmission Control Protocol TCP socket in client mode established on a target port, wherein the registration request is used to register the full-cone edge sub-device in the detection keepalive server;

[0065] An establishing unit 502 is configured to establish a TCP socket in server mode on the target port after receiving a registration response message sent by the detection keep-alive server through the TCP socket in client mode;

[0066] The processing unit 503 is configured to extract a public network address from a first keep-alive message sent periodically by the detection keep-alive server after receiving the first keep-alive message through the TCP socket in the server mode;

[0067] The second registration unit 504 is configured to register the HTTP service provided by the full-cone edge sub-device according to the public network address, so that the client accesses the full-cone edge sub-device through the public network address to use the HTTP service.

[0068] The registration request sent by the first sending unit 501 to the detection keep-alive server may further include identification information of the full-cone edge sub-device, and the identification information may be a device ID, a device name, and the like.

[0069] Therefore, the detection keep-alive server of this embodiment registers the full-cone edge sub-device, that is, the detection keep-alive server records the correspondence between different edge sub-devices and different identification information.

[0070] When the first sending unit 501 sends a registration request to the detection keep-alive server through a TCP socket in client mode, the registration request can be first sent to an edge master device (such as an edge gateway, edge router, etc.) through a TCP socket in client mode established on the target port, and then the edge master device forwards the registration request to the detection keep-alive server; wherein, the edge master device is connected to at least one edge sub-device, and the edge master device can determine the public network address of each edge sub-device connected to it.

[0071] In this embodiment, when the edge master device forwards the registration request sent by the full-cone edge sub-device to the detection keep-alive server, it can also determine the public network address of the full-cone edge sub-device, add the public network address to the registration request, and then send the registration request to the detection keep-alive server.

[0072] In this embodiment, after the first sending unit 501 sends a registration request to the detection keep-alive server through the client mode TCP socket established on the target port, the establishing unit 502 establishes a server mode TCP socket on the target port after receiving the registration response message sent by the detection keep-alive server through the client mode TCP socket.

[0073] If the establishment unit 502 receives a registration response message sent by the detection keep-alive server, it indicates that the detection keep-alive server has completed the registration of the full-cone edge sub-device; if the full-cone edge sub-device does not receive a registration response message within a period of time, it indicates that the registration is unsuccessful, and it can send a registration request to the detection keep-alive server again, and repeat this cycle until the registration response message is received or the number of registration requests sent reaches the preset number.

[0074] The establishment unit 502 can receive the registration response message forwarded by the edge master device through the client mode TCP socket established on the target port; and the registration response message forwarded by the edge master device is sent to the edge master device after the detection keep-alive server completes the registration of the full-cone edge sub-device. The detection keep-alive server can add the public network address of the full-cone edge sub-device to the registration response message, so that the edge master device can accurately forward the registration response message according to the public network address in the registration response message.

[0075] After receiving the registration response message, the establishment unit 502 establishes a server mode TCP socket on the target port of the client mode TCP socket; the server mode TCP socket can communicate directly with the detection keep-alive server or client without going through the edge master device.

[0076] After receiving the registration response message sent by the detection keep-alive server, the establishing unit 502 may further execute the following: closing the TCP socket in client mode established on the target port.

[0077] After the establishment unit 502 establishes a server mode TCP socket on the target port, the processing unit 503 of the full-cone edge sub-device of this embodiment extracts the public network address from the first keep-alive message after receiving the first keep-alive message sent periodically by the detection keep-alive server through the server mode TCP socket.

[0078] That is to say, the detection keep-alive server of this embodiment will continuously send the first keep-alive message to the full-cone edge sub-device at a certain time interval. If the full-cone edge sub-device can receive the first keep-alive message, it indicates that the full-cone edge sub-device can be accessed through TCP or HTTP, that is, it can provide HTTP service; if the full-cone edge sub-device does not receive the first keep-alive message, it indicates that the full-cone edge sub-device cannot provide HTTP service.

[0079] After the processing unit 503 extracts the public network address from the first keep-alive message, the second registration unit 504 registers the full-cone edge sub-device according to the public network address and the HTTP service provided by the full-cone edge sub-device in this embodiment, so that the client can access the full-cone edge sub-device through the public network address to use the HTTP service.

[0080] The HTTP service in this embodiment is a service based on HTTP requests, such as a network disk service, a web page service, etc. Data can be stored and downloaded through the network disk service, and web pages can be browsed through the web page service.

[0081] When registering based on the public network address and the HTTP service provided by the full-cone edge sub-device, the second registration unit 504 can be registered in the domain name server or the address server, so that the correspondence between the public network address of the full-cone edge sub-device and the HTTP service provided by the full-cone edge sub-device is recorded in the domain name server or the address server.

[0082] After completing the registration of the public network address and HTTP service of the full-cone edge sub-device, the relevant client can query the domain name server or address server according to the HTTP service to be used, and then access the corresponding full-cone edge sub-device according to the public network address obtained from the query to perform related operations such as data storage or downloading, or web browsing.

[0083] The device 500 for providing HTTP service in this embodiment may also include a third sending unit 505, which is used to perform the following contents: detecting whether the TCP socket in client mode is closed; when it is determined that the TCP socket in client mode is not closed, periodically sending a second keep-alive message to the detection keep-alive server through the TCP socket in client mode, so that after the detection keep-alive server receives the second keep-alive message periodically sent by the full-cone edge sub-device, it registers with the HTTP service provided by the full-cone edge sub-device according to the public network address of the full-cone edge sub-device.

[0084] That is to say, the third sending unit 505 can also continuously send the second keep-alive message to the detection keep-alive server through the TCP socket at a certain time interval without closing the TCP socket in client mode, so that the detection keep-alive server can know that the full-cone edge sub-device is in a survival state, and then the detection keep-alive server executes the registration of the public network address and its corresponding HTTP service, which can improve the registration efficiency.

[0085] When the third sending unit 505 periodically sends the second keep-alive message to the detection keep-alive server through the TCP socket in client mode, it can first send the second keep-alive message to the edge master device through the TCP socket in client mode, and then the edge master device forwards the second keep-alive message to the detection keep-alive server.

[0086] Figure 6 Schematic diagram of the sixth embodiment of the present disclosure. Figure 6 As shown, the apparatus 600 for providing HTTP service in this embodiment is applied to detect a keep-alive server, and includes:

[0087] A first registration unit 601 is configured to register the full-cone edge sub-device after receiving a registration request sent by the full-cone edge sub-device, wherein the registration request is sent by the full-cone edge sub-device through a TCP socket in client mode established on a target port;

[0088] The second sending unit 602 is configured to generate a registration response message and send it to the Full Cone Edge sub-device, where the registration response message is used by the Full Cone Edge sub-device to establish a TCP socket in server mode on a target port.

[0089] The fourth sending unit 603 is used to periodically send a first keep-alive message to the full-cone edge sub-device, and the full-cone edge sub-device receives the first keep-alive message through the TCP socket in the server mode. The first keep-alive message includes the public network address corresponding to the full-cone edge sub-device.

[0090] The first registration unit 601 can obtain a registration request forwarded by the edge master device corresponding to the full-cone edge sub-device, and the registration request includes the identification information of the full-cone edge sub-device; when the detection keep-alive server of this embodiment registers the full-cone edge sub-device, it specifically records the correspondence between the full-cone edge sub-device and the identification information.

[0091] After registering the full-cone edge sub-device, the first registration unit 601 can also extract the public network address corresponding to the full-cone edge sub-device from the registration request. The public network address is added when the edge master device corresponding to the full-cone edge sub-device forwards the registration request to the detection keep-alive server.

[0092] In this embodiment, after the first registration unit 601 registers the full-cone edge sub-device, the second sending unit 602 of the detection keep-alive server generates a registration response message and sends it to the full-cone edge sub-device.

[0093] It is understandable that, when generating the registration response message, the second sending unit 602 may further obtain the public network address corresponding to the full-cone edge sub-device, and then add the public network address to the registration response message.

[0094] In this embodiment, after the second sending unit 602 of the detection keepalive server generates a registration response message and sends it to the full-cone edge sub-device, the fourth sending unit 603 periodically sends a first keepalive message to the full-cone edge sub-device.

[0095] When the fourth sending unit 603 sends the first keep-alive message to the full-cone edge sub-device at regular intervals, it can send the first keep-alive message to the full-cone edge sub-device at regular intervals according to the public network address corresponding to the full-cone edge sub-device; wherein the first keep-alive message includes the public network address of the full-cone edge sub-device.

[0096] The apparatus 600 for providing HTTP services in this embodiment may further include a third registration unit 604 for performing the following operations: after receiving the second keep-alive message sent periodically by the full-cone edge sub-device, registering with the HTTP service provided by the full-cone edge sub-device according to the public network address.

[0097] The second keep-alive message received by the third registration unit 604 is sent by the full-cone edge sub-device through the TCP socket in client mode; similarly, the detection keep-alive server can obtain the second keep-alive message forwarded by the edge master device.
