Example three:
for better understanding of the present invention, the present embodiment proposes a more specific example to illustrate the present invention;
in the related art, when the CPE has a multi-WAN (Wide Area Network) port characteristic, an application scenario of the multi-WAN port is based on a Network priority policy, a Network anomaly detection, and an automatic Network switching mechanism. For example, the 5G CPE supports 5G NR wireless communication, simultaneously supports a broadband mode, and when the 5G NR wireless coverage and the wired Ethernet WAN port exist, the priority strategy of the default WAN port is to preferentially use the wired Ethernet, and when the wired Ethernet is abnormal, the abnormality is automatically detected and the 5G NR wireless network is switched to. For an application scenario using TCP IP, such as an industrial automation control scenario, a control instruction may be interrupted, because a certain time is required for anomaly detection of a network, and a WAN port switching after an anomaly is detected is based on a hard switching mechanism, and an idle period without a network inevitably occurs. This idle period, in addition to possibly causing data loss, may also cause the TCP Connection of the application to be interrupted, requiring the application to reestablish the TCP Connection. For industrial automation scenarios, this interruption and data loss is unacceptable;
in order to solve the problems of network interruption and data loss of the terminal, in the embodiment, a layer of software component of a multi-WAN agent is added to a TCPIP protocol stack, and a data transmission method executed by the software component completes detection and management of a multi-WAN network card, copying of application data at a CPE side, and binding of multiple WANs; meanwhile, the Server side compares and combines the application data through the data transmission method to complete redundant data receiving and sending based on redundant WAN resources, and further, the reliability and stability of communication data are improved on the premise of not sacrificing communication bandwidth and speed. The method solves the problems of small probability data interruption, TCP Connection interruption and reconnection caused by network link instability. The user application layer can achieve the user experience of continuous connection.
In some examples, a software component of a "multi-WAN agent" is correspondingly a ba (binding agent) software component on the CPE side to perform a data transmission method, and a ca (combination agent) component on the Server side to perform a data reception method; for example, there are two communication entities, namely, a Hybrid CPE and a Hybrid Server, wherein the Hybrid CPE integrates a binding Agent software component, and the Hybrid Server integrates a combination Agent software component. The binding Agent software component comprises three modules of 'data receiving and backup', 'main path sending' and 'auxiliary path sending'. The Hybrid Server software component comprises three modules of 'data receiving and merging', 'primary receiving' and 'secondary receiving', wherein, the communication schematic diagram of the Hybrid CPE and the Hybrid Server is shown in FIG. 4, it should be understood that, the binding Agent and the combination Agent are collectively called 'multi-WAN Agent', and the position of the software component in the TCPIP protocol stack is shown in FIG. 5; the internal structure of the binding Agent and combination Agent is shown in FIG. 6. In some examples, the Hybrid CPE and the Hybrid Server perform a data transmission method, as shown in fig. 7, which includes but is not limited to:
s701, connecting the CPE to networks of different systems;
in some embodiments, the CPE has a plurality of network cards, wherein the CPE performs registration of the wireless cellular network after being powered on, the registration process may be registered to an LTE standard or an NR standard as a first standard network, the wireless network card corresponds to the WAN1 unit, and the CPE starts the wired network card, corresponds to the WAN2 unit, and is connected to the ethernet network as a second standard network.
S702, starting a Binding Agent (BA) unit at the CPE side; the Combination Agent (CA) unit is started on the Server side.
In some examples, the BA unit includes a data receiving and backup module, a primary transmission module, and a secondary transmission module to thereby be able to perform the steps of the data transmission method. Correspondingly, the CA unit includes a data receiving and merging module, a main receiving module and a sub receiving module, and is further capable of executing the steps of the data transmission method.
S703, a data receiving and backup module of the BA unit receives an original data packet from a CPE application layer and performs copy operation on the original data packet;
in some examples, the original data packet is copied to obtain a backup data packet, and then the original data packet is sent to the primary route sending module, and the backup data packet is sent to the secondary route sending module.
S704, establishing a socket;
in some examples, the master transmitting module of the BA unit creates a socket1 based on the WAN1 network card and the connected first-format network and transmits the original data packet through the socket 1. And a secondary path sending module of the BA unit creates a socket2 based on the WAN2 network card and the connected second-system network and sends out the copied data packet through the socket 2. When the transport layer data is transmitted, socket1 and/or socket2 will have the same sequence number, which identifies the original data packet and the spare data packet.
S705, a CA unit receives data;
in some examples, the master receive module of the CA unit listens to socket1 and receives the original data packet from the BA unit master transmit module and transmits the original data to the data receive and merge module of the CA unit. The auxiliary receiving module of the CA unit monitors the socket2 and receives the standby data packet from the auxiliary transmitting module of the BA unit, and transmits the standby data packet to the data receiving and merging module of the CA unit.
S706, analyzing the original data packet and the standby data packet by the CA unit to obtain a complete data packet;
in some examples, the data receiving and merging module of the CA unit compares the original data packet and the spare data packet according to the packet sequence numbers, and performs the merging process. For example, data received by the master (source is socket1) may be stored in buffer1, data received by the slave (source is socket2) may be stored in buffer2, the buffer data may be analyzed to obtain the transport layer sequence numbers of socket1 and socket2, the buffer data of socket1 may be preferentially used when merging the data, and when the original packet is found to have sequence number interruption, the missing sequence number data may be copied from the buffer data of socket2, thereby forming complete merged data.
S707, the CA unit analyzes effective application data;
in some examples, the data receiving and merging module of the CA unit sends the merged data packet to the application layer of the Server, and the Server application layer parses out valid application data.
In the data transmission method provided by this embodiment, the CPE is connected to networks of different systems, and a Binding Agent (BA) unit is started at the CPE side; a Combination Agent (CA) unit is started on a Server side, a data receiving and backup module of the BA unit receives an original data packet from a CPE application layer, the original data packet is copied to establish a socket, the CA unit receives data, the CA unit analyzes the original data packet and a standby data packet to obtain a complete data packet, and the CA unit analyzes effective application data. And data redundancy operation is completed through data copying of the BA unit, and then redundant data sorting work is completed through data comparison and combination of the CA unit. Through the transmission of redundant data on a redundant network card resource WAN2 unit, the high-reliability transmission between a CPE application layer and a Server application layer is ensured, and the problem of short-time link interruption caused by WAN1 or WAN2 wireless link abnormity is solved.
