Embodiment 1

[0146] The network communication system for cross-communication protocol data forwarding in this embodiment includes: a network unit, a client and a server; wherein the network unit includes a network service device;

[0147] Such as Figure 4 As shown, the computer 1 runs the program PA as the network service device, the computer 1 runs the program CA as the client, and an environmental control device D2 acts as the server; the environmental control device D2 is connected to the computer 1 through the USB interface and communicates with the program PA, The program PA opens a UDP port of the TCPIP communication protocol, the program CA is connected to the UDP port of the program PA, the UDP connection port number of the program CA is XXXX, the program CA sends a service request data packet, and the environmental control device D2 sends a service response data packet, the service request The data packet and the service response data packet both contain the service identificatio...

Embodiment 2

[0169] The network communication system for cross-communication protocol data forwarding in this embodiment adds a client and a server on the basis of the first embodiment.

[0170] The service request data packet and the service response data packet are added with data length information and an additional function code for additionally defining the service function code FID. A timing identifier is added to each record in the return routing table, and the timing identifier is updated when the service identifier S_INFO and the peer communication address peer_addr records are inserted and updated. The service request data packet and the service response data packet add multiple switch values ​​respectively: the second bit of the switch value is a multi-function switch, the third bit is a user switch, the fourth bit is a priority switch, and the fifth bit is a Delete switch, the 6th bit is a single switch, and the 7th bit is a serial number switch.

[0171] Since USB communicati...

Embodiment 3

[0239] Such as Figure 5 As shown, the network communication system for cross-communication protocol data forwarding in this embodiment is based on the second embodiment, adding multiple network service devices to form a three-layer network unit. Also add a visual manipulator on computer 1, the program PA opens a TCP port of the TCPIP communication protocol, the visual manipulator connects to the TCP port of the program PA through communication, and obtains the integer 4 as the server ID DID; the visual manipulator provides 4 service function codes FID, the integer 0x000A corresponds to the online test function, the integer 0x000B corresponds to the communication connection test function, the integer 0x1001 corresponds to the motion control function, and the integer 0x2000 corresponds to the video stream.

[0240] The network service device in the network unit is divided into three levels, including the first-level network service device at the highest level, the second-level ...

Abstract

The invention relates to a cross-communication protocol data forwarding network communication system, a method and a device thereof. A service identifier S_INFO in a service request data packet sent to a server side by a client side through a network service device comprises at least one of first addressing information of the server side and a plurality of service function codes FIDs provided in the server side; one or more network service devices forward the service request data packet to the server for the client; and a first corresponding relation is established between the service responsedata packet responded by the server and the service request data packet according to the service identifier S_INFO, and according to the first corresponding relation, the network service device searches a path of the corresponding service request data packet for the service response data packet to return the service response data packet to the client. The system provided by the invention can spana plurality of countries and regions to deploy network units of ten billion orders of magnitudes to form a complete system, so that any two endpoints in the system have a communication capability.

Description

technical field [0001] The invention relates to the technical fields of the Internet and the Internet of Things, in particular to a network communication system, method and device for data forwarding across communication protocols. Background technique [0002] The Internet connects the world based on the TCPIP protocol, and the emergence of the Internet of Things is because in many occasions, the TCPIP protocol is not applicable. The Internet of Things uses various communication protocols to form a network, and then connects to the Internet through the Internet of Things gateway. Contents of the invention [0003] The technical problem to be solved by the present invention is that there are various ways of communication between various device endpoints or program endpoints in the Internet and the Internet of Things, and it is impossible to ensure that any two endpoints have communication capabilities. The present invention provides a network communication system, method a...
