Therefore, a second protocol directly connected with the bottom layer is not needed, the difference of service data of the first protocol is shielded, and the later maintenance cost is reduced.
Referring to fig. 1, a step flow chart of a data transmission method provided by an embodiment of the present invention is shown, where the method is applied to a client, and the client is provided with an intermediate layer including a plurality of first preset ports; the middle layer is used for packaging the service data by adopting a first protocol; the client is in communication connection with the server, and the method specifically comprises the following steps:
step 101, determining a corresponding target port from the plurality of first preset ports according to the service type of the service data to be transmitted and the first preset corresponding relation of the middle layer.
In the embodiment of the invention, the client can be a command line client, the server can be a command line server, the client can be installed and operated on a Linux PC, the video network is accessed by a virtual terminal mode, the server can be installed and operated in a Linux server, and the video network is accessed by a virtual terminal mode. As shown in fig. 2, a block diagram of a device connection structure provided by an embodiment of the present invention is shown, where a client of a conference room area, a client of an operation and maintenance area, and a server are respectively connected with a switch, and the switch is connected with an internet of vision. The clients of the meeting area are used for users, and the clients of the operation and maintenance area are used for maintenance of the system and the clients by operation and maintenance personnel.
In the embodiment of the present application, the service data may be service data of a first protocol, and before the client determines the corresponding target port according to the service type of the service data, the communication connection between the client and the server may be established, and the communication connection between the client and the server may be established by the following manner: acquiring address information and a video networking number of a server; and establishing communication connection with the corresponding server according to the address information and the video networking number. Specific: the user can send a request instruction to the server through the client, the request instruction can comprise address information and an internet-of-view number of the server which needs to generate communication connection, and the server generates communication connection with the client in response to the request instruction after receiving the request instruction. The client may send the request command to the switch, and the switch forwards the request command to the server.
After the communication connection between the client and the server is established, the client may start to acquire service data to be transmitted, where the service data may be ssh (remote connection service), telnet (remote login service), ftp (file transfer service), or may be third party service data. The content of the service data can be set according to actual requirements, and the application is not particularly limited herein.
In the embodiment of the invention, the client may be provided with an intermediate layer, the intermediate layer may be provided with a plurality of first preset ports, a first preset corresponding relationship is further provided in the intermediate layer, the first preset corresponding relationship may be a corresponding relationship between a service type of service data and the first preset ports, and the intermediate layer may be websocket. The invention can determine the target port corresponding to the service type from a plurality of first preset ports according to the service type of the service data to be transmitted and the first preset correspondence. For example: the service type of the service data to be transmitted is ssh, then a port corresponding to the service type of ssh may be determined from a plurality of first preset ports according to the first preset corresponding relationship, and the determined port is determined as the port for transmitting the service data with the service type of ssh.
And 102, sending the service data to the middle layer through the target port, and packaging the service data through the middle layer to obtain a first packaging data packet of the first protocol.
In the embodiment of the invention, after the corresponding target port is determined from the plurality of first preset ports, the service data can be sent to the middle layer through the target port. For example: and transmitting the service data with the service type of ssh to the middle layer by determining the port with the service type of ssh. The middle layer may then encapsulate the traffic data. In the middle layer of the invention, the business data can be encapsulated by adopting a first protocol, so as to obtain a first encapsulated data packet of the first protocol. The first protocol in the present invention may be a TCP/IP (Transmission Control Protocol/Internet Protocol ) protocol.
In an example, the service data of the present invention may include data of different service types, and when the service data is encapsulated, the service data of the same service type may be encapsulated into the same data packet according to the service type of the service data, so as to obtain first encapsulated data packets of a plurality of first protocols. For example: the service data is 5 groups of data, wherein the first group and the second group are data with the same service type, the third group and the fourth group are data with the same service type, and the fifth group is data with another service type, so that the data of the first group and the second group can be packaged into the same data packet, the data of the third group and the fourth group are packaged into the same data packet, and the data of the fifth group is packaged into one data packet, thereby obtaining first packaged data packets of three first protocols.
Step 103, converting the first encapsulated data packet into a second encapsulated data packet of a second protocol.
In the embodiment of the invention, after the client obtains the first encapsulated data packet of the first protocol, the client can convert the first encapsulated data packet into the second encapsulated data packet of the second protocol. The second protocol in the present invention may be a V2V protocol. The first encapsulated packet may be converted to a second encapsulated packet of a second protocol by a conversion layer in the client, which may be a lwip (Light Weight) TCP/IP protocol transceiver module. The lwip transceiver module may convert the first encapsulated packet of the TCP/IP protocol into a second encapsulated packet of the V2V protocol.
104, transmitting the second encapsulated data packet to the server, so that the server receives the second encapsulated data packet of the second protocol sent by the client, converts the second encapsulated data packet into a first encapsulated data packet of the first protocol, and decapsulates the first encapsulated data packet to obtain the service data; determining a corresponding service port from a plurality of second preset ports according to the service type of the service data and a second preset corresponding relation, and sending the service data to the service port so that the service port provides corresponding service for the service data; the second preset corresponding relation is a corresponding relation between the service type and the second preset port.
In the embodiment of the present invention, after converting the first encapsulated packet into the second encapsulated packet of the second protocol, the client may transmit the second encapsulated packet to the server based on a preset interface, where the preset interface may be a transceiver interface of the V2V protocol. For example, after the lwip transceiver module converts the first encapsulated data packet of the TCP/IP protocol into the second encapsulated data packet of the V2V protocol, the transceiver interface of the V2V protocol may be mobilized to send the second encapsulated data packet to the server, and after receiving the second encapsulated data packet, the server may convert the second encapsulated data packet into the first encapsulated data packet, and decapsulate the first encapsulated data packet to obtain service data. For example: after receiving the second encapsulated data packet of the V2V protocol, the server may convert the second encapsulated data packet into a first encapsulated data packet of the TCP/IP protocol, and then decapsulate the first encapsulated data packet of the TCP/IP protocol, thereby obtaining service data. The service end can determine the corresponding service port from the second preset ports according to the service type of the service data and the second preset corresponding relation, and send the service data to the service port, so that the service port provides corresponding service for the service data. The second preset corresponding relation is a corresponding relation between the service type and the second preset port. Therefore, when the service or data of the third party application is migrated to the second protocol network environment, the second protocol of the bottom layer of the second protocol network is not required to be docked, only the middle layer of the client is required to be docked, and for later maintenance, only the unified preset interface in the middle layer is required, so that the maintenance cost is effectively reduced.
Referring to fig. 3, a step flowchart of another data transmission method provided by an embodiment of the present invention is shown, where the method is applied to a server, and the server includes a plurality of second preset ports; the service end is in communication connection with the client end, and the method specifically comprises the following steps:
step 301, receiving a second encapsulated packet of a second protocol sent by the client; the second encapsulation data packet is obtained by determining a corresponding target port from a plurality of first preset ports by the client according to the service type of the service data to be transmitted and a first preset corresponding relation of an intermediate layer, sending the service data to the intermediate layer through the target port, encapsulating the service data through the intermediate layer to obtain a first encapsulation data packet of a first protocol, and converting the first encapsulation data packet by the client; the client is provided with the middle layer comprising a plurality of first preset ports; the middle layer is used for packaging the service data by adopting a first protocol; the first preset corresponding relation is the corresponding relation between the service type of the business data and the first preset port.
In the embodiment of the invention, before receiving the second encapsulated data packet of the second protocol sent by the client, the server can establish communication connection with the client according to the address information and the video networking number corresponding to the server. Specific: the user can send a request instruction to the server through the client, the request instruction can comprise address information and an internet-of-view number of the server which needs to generate communication connection, and the server generates communication connection with the client in response to the request instruction after receiving the request instruction. The client may send the request command to the switch, and the switch forwards the request command to the server.
After the communication connection between the server and the client is established, the server may receive a second encapsulated packet of a second protocol sent by the client.
In the invention, the second encapsulated data packet can be determined by the client from a plurality of first preset ports according to the service type of the service data to be transmitted and the first preset corresponding relation of the middle layer, then the service data is sent to the middle layer through the target ports, then the service data is encapsulated through the middle layer to obtain the first encapsulated data packet of the first protocol, and the client converts the first encapsulated data packet to obtain the second encapsulated data packet. Wherein, the client may be provided with an intermediate layer comprising a plurality of first preset ports; the middle layer can adopt a first protocol to package service data; the first preset corresponding relation is the corresponding relation between the service type of the business data and the first preset port.
Step 302, converting the second encapsulated data packet into a first encapsulated data packet of a first protocol.
In the embodiment of the invention, after receiving the second encapsulated data, the server may convert the second encapsulated data packet into the first encapsulated data packet of the first protocol. In the invention, a V2V network card (vvnecard) can be arranged in the service end, and the received second encapsulated data packet of the two protocols can be converted into the first encapsulated data packet of the first protocol through the V2V network card. For example: after the V2V network card receives the second encapsulated packet of the V2V protocol, the second encapsulated packet of the V2V protocol may be converted into the first encapsulated packet of the TCP/IP protocol.
Step 303, decapsulating the first encapsulated data packet to obtain service data of the first protocol.
In the embodiment of the invention, the server side converts the second encapsulated data packet into the first encapsulated data packet of the first protocol, and can perform decapsulation processing on the first encapsulated data packet. In the invention, the websocket agent can be provided by a third party and is arranged in the server so as to generate a processing process, the websocket in the client and the websocket agent in the server have a corresponding relation, and the ports arranged in the websocket of the client can be arranged according to the ports arranged in the service ports by the websocket agent so as to form a corresponding relation.
Step 304, determining a corresponding service port from the second preset ports according to the service type and the second preset corresponding relation of the service data, and sending the service data to the service port, so that the service port provides corresponding service for the service data; the second preset corresponding relation is a corresponding relation between the service type and the second preset port.
In the embodiment of the invention, after the service end obtains the service data of the first protocol by decapsulating the first encapsulated data packet, the service data can be forwarded to the corresponding service port. In the invention, a plurality of second preset ports and a second preset corresponding relation can be arranged in the service end. The second preset corresponding relation may be a corresponding relation between the service type and the second preset port. The second preset port and the second preset corresponding relation may be set in a websocket. The service end can determine the corresponding service port from the second preset ports according to the service type of the service data and the second preset corresponding relation, and send the service data to the service port, so that the service port provides corresponding service for the service data. For example: and if the service type of the service data is ssh, determining a port corresponding to the service type of ssh from a plurality of second preset ports according to the second preset corresponding relation. Then, the service data with the service type of ssh can be sent to the service port corresponding to the service type of ssh, so that the port corresponding to the service type of ssh provides corresponding service for the service data with the service type of ssh.
In an example, after obtaining the service data of the first protocol, the server may parse the service data to obtain parsed data and a corresponding service type; determining a corresponding service port from a plurality of second preset ports according to the service type and the second preset corresponding relation; and forwarding the analysis data to a corresponding service port so that the service port provides corresponding business service for the analysis data. For example: after the service data of the first protocol is obtained, the service data is analyzed, and service types corresponding to the analyzed data are ssh, telnet, ftp respectively, so that the data with the service type of ssh analysis can be forwarded to the sshd port, the data with the service type of telnet analysis can be forwarded to the telnet port, and the data with the service type of ftp analysis can be forwarded to the vsftpd port, thereby enabling the service port to provide corresponding service for the service data. Therefore, when the service or data of the third party application is migrated to the second protocol network environment, the second protocol of the bottom layer is not required to be directly docked, only websocket of the client is required to be docked, and for later maintenance, only unified preset interfaces are required to be maintained, so that the maintenance cost is effectively reduced.
