Abstract
The invention discloses a network real-time communication method and a system thereof, relating to the field of network communication. The network real-time communication method comprises the following steps: the communication software of the equipment 1 collects video and audio signals and encodes the video and audio signals into video stream data; sending out video stream data through the data relay equipment 1; the data relay device 2 receives the video stream data and transmits the data to the device 2; the device 2 converts the coded video stream data into audio and video for playing through communication software. The two data relay devices of the invention both need to support MPTCP protocol, are compatible with IPV4 and IPV6 protocols, and need to have independent public network IP, and communication software also needs to support IPV6 for access. The communication equipment and the data relay equipment can be connected in various ways (such as USB line connection, WIFI connection, Bluetooth connection and the like). On the premise of not upgrading any hardware and system firmware of two devices for real-time communication, the invention solves the problems of disconnection caused by unstable signals, unsafe data transmission process, possibility of interception and utilization by illegal persons and the like in the traditional network real-time communication process in a low-cost mode.

Background
Most of network real-time communication software at present, when providing a real-time communication function, both ends of communication are often required to be connected to a communication software server, most of domestic communication software servers and client devices do not support IPV6, and IP address resources provided by IPV4 are also consumed, most of client devices do not have a stable available IP address, all data generated by communication need to be forwarded on the server, and IPV4 data packets are transmitted in plaintext, data security cannot be guaranteed, and the conventional TCP connection mode only supports one link at present, once a user or a communication server network fluctuates or fails, the whole communication card is suspended or even interrupted.
Disclosure of Invention
The invention mainly aims to provide a network real-time communication method and a system thereof, which are used for solving the problems of low safety and poor stability of the conventional communication system.
In order to achieve the above object, the present invention provides a network real-time communication method, which comprises the following steps:
the device 1 opens communication software to collect video and audio signals and encodes the video and audio signals into video stream data;
sending out video stream data through the data relay equipment 1;
the relay device 2 receives the video stream data and transmits the data to the device 2;
the device 2 converts the coded video stream data into audio and video for playing through communication software.
Wherein, both data relay devices need to support the MPTCP protocol, are compatible with the IPV4 and IPV6 protocols, and need to have independent public network IP.
The communication software needs to support an IPV6 protocol, can send and receive data through the IPV6 protocol, and supports real-time encoding and decoding of audio and video data.
When two client devices communicate, all communication data do not need to pass through a third-party server, but are directly transmitted through the IPV6 network.
The invention also provides a network real-time communication method system, and the communication system comprises the client equipment 1, the client equipment 2, the data relay equipment 1, the data relay equipment 2 and a communication software server.
The data relay device may include multiple network cards and support the MPTCP protocol; any two network cards of two data relay devices can establish a TCP sub-link, and an MPTCP link comprises a plurality of TCP sub-links.
The MPTCP link supports seamless flow switching, and when a sub-link under the MTTCP is disconnected due to a problem, the flow is automatically switched to other normal sub-links.
The communication among any TCP sub-link is based on an IPV6 protocol, the communication content is encrypted and transmitted in a network layer, and the security of the transmission process is ensured.
The invention realizes the real-time communication function of point-to-point in the network by adding a data relay device without any upgrading and transformation of user equipment, and solves the problems of data security and communication quality stability under the condition of network fluctuation in the real-time communication process of the traditional network with ultralow cost.

(2) The client device 2 connects to the communication software server and transmits the IPV6 address of the data relay device 2 connected to the client device 2, and the connection between the client device 1 and the communication software server may be a normal TCP connection based on IPV 4.
(3) The client device 1 requests the server to obtain the IPV6 address provided by the client device 2 with which it wants to communicate, each client has its corresponding unique identifier in the communication software server, and two communicating clients should store as friends in the communication software.
(4) The client device 1 controls the data relay device 1 to connect with the data relay device 2 through the obtained IPV6 address, where the connection is a point-to-point connection between two clients, and no other device is needed to provide services, including a communication software server.
(5) The connection between the data relay device 1 and the data relay device 2 is based on the MPTCP protocol, and each of the two data relay devices includes a plurality of network cards and establishes a plurality of sub-links, as shown in fig. 2.
(6) If a certain network card or some sub-links have problems in the communication process, the MPTCP protocol can automatically and seamlessly switch the flow to the normal sub-links, so that the data transmission is not influenced by the overall communication stability due to network faults in a certain small range.
(7) And the two data relay devices receive and transmit video stream data generated by real-time coding of the communication software to finish the communication process.
