the public network client sends a websocket connection request to the public network server, and when the connection request is sent, permission verification information needs to be attached. And the verification information is prepared without error, and the public network server and the public network client establish websocket connection.
When the intranet server and the public network server are installed and deployed, an open port configuration is performed on the firewall, for example, an 8080 port is selected as a communication port between the public network and the intranet, and after the port is opened, a high-speed full-duplex communication channel is established between the public network and the intranet based on a websocket communication protocol to perform real-time communication.
The intranet is connected with a real-time picture or a structured data stream generated by the image and video acquisition equipment information, and pushes data to a public network server side in real time through a websocket full-duplex communication channel of the public network.
The plurality of public network service terminals form a public network service terminal cluster, data transmitted from the internal network are subjected to real-time service processing, and are pushed to the public network client terminal in real time under the control of the public network service terminal websocket communication control module.
As shown in fig. 3, the public network server has a plurality of topics for publishing/subscribing, the public network client establishes a websocket channel to the public network server with the client unique identifier client _ id through a certain topic1, and sets the subscription identifier is _ sub _ flag to true through the channel to send the subscription identifier is _ sub _ flag. The public network server side assembles client _ id and is _ sub _ flag into a subscription client object subObject which is stored in a subscription client queue of the topic1, when a message which belongs to the topic1 from an internal network arrives, the public network server side can take out all objects in the subscription client queue of the topic1, and when the is _ sub _ flow of a certain object is true, the public network server side sends the message through a websocket connecting channel which is established by the topic1+ the client terminal and uniquely identifies the client _ id. When a client wants to unsubscribe, the client sets the is _ sub _ flag to be false and sends the is _ sub _ flag through a websocket connection channel established by the topic1 and the client-side unique identification client _ id, and the public network server sets the is _ sub _ flag of the client-side object subscribed by the client _ id to be false and then unsubscribes.
A peer-to-peer message pushing module, as shown in fig. 4, a client of the public network sets a topic _ p2p for pushing a specific message peer-to-peer and a type identifier type _ id of a plurality of specific messages, the client of the public network establishes a websocket connection channel with a client unique identifier client _ id1 through the topic _ p2p, the type identifier type _ id1 of the specific message to be received is sent through the channel, the server of the public network takes the type _ id1 as a key, the client _ id1 is stored in the map, when the specific message with the type identifier type _ id1 from the internal network arrives, the client _ id1 is taken out according to the type _ id1, and the specific peer-to-peer message pushing is realized through a websocket channel established by the topic _ p2p and the client unique identifier client _ id 1.
In the embodiment, based on the websocket cross-domain communication technology, message subscription/publishing and point-to-point message pushing are realized. Because the service module and the full-duplex communication module are fused on one server, service and a firewall port do not need to be separately deployed for full-duplex communication, and an additional communication assembly does not need to be integrated.
