Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flowchart illustrating steps of a method for network communication according to an embodiment of the present invention is applied to a first inter-network data processing service located in a first network area in a non-IP network.
In an example, the non-IP network may be a heterogeneous network with the IP network, in which a plurality of independent network areas (the network areas may also be referred to as autonomous domains) may be disposed, for example, the non-IP network may be a video network, which is a real-time high-speed transmission network based on ethernet hardware, and a private network for transmitting high-definition video and a private protocol.
In one example, an inter-network data processing service may be used to handle protocol conversion between IP network data packets and non-IP network data packets, such as an inter-network data processing service being a protocol conversion service.
Specifically, the method comprises the following steps:
step 101, based on the first IP network connection, receiving an IP network packet sent by a first end located in the first network area, and converting the IP network packet into a non-IP network packet.
The first end and the second end may be communication ends where application programs based on the IP network protocol are located, that is, the operation of the first end and the second end depends on the IP network protocol, and the first end and the second end can only generate and process IP network data packets.
In an example, the communication end may be a client (e.g., a client deployed in an internet of view terminal), a server (e.g., a server deployed in an internet of view server), for example, the first end is a client and the second end is a server, or the first end is a server and the second end is a client, or the first end is a client and the second end is a client, or the first end is a server and the second end is a server.
It should be noted that, although the first end and the second end are communication ends where the application program based on the IP network protocol is located, the first end and the second end are located in a non-IP network, not in an IP network, and the first end and the second end cannot use the IP network for communication.
In an example, the IP network protocol may be TCP (Transmission Control Protocol ), HTTP (Hypertext Transfer Protocol, hypertext transfer protocol), the IP network connection may be a TCP connection, an HTTP connection, the IP network packet may be a TCP packet, an HTTP packet, or any other IP network-based protocol.
When the IP network protocol is HTTP, one of the first and second ends is a browser, and the other end is a WEB site, which may be a browser at the first end and a WEB site at the second end, or may be a WEB site at the first end and a browser at the second end.
The first end may be located in a first network area of the non-IP network, the second end may be located in a second network area of the non-IP network, and the first network area and the second network area may be independent network areas.
When a first end in a first network area is to communicate with a second end in a second network area, that is, a cross-domain communication service is to be performed between different network areas, the first end can generate an IP network data packet based on an IP network protocol, the IP network data packet adopts an IP network protocol packet header, and a destination address of the IP network data packet is an IP address and a port of the second end.
Because the first end and the second end cannot communicate through the IP network, and the non-IP network cannot be compatible with the IP network data packet generated by the first end, the first end may send the generated IP network data packet to the first inter-network data processing service in the first network area where the first end is located.
In an example, since the first inter-network data processing service and the first end are located in the same network area, the first inter-network data processing service and the first end may use an IP local area network for communication, and of course, if the first inter-network data processing service and the first end are located in the same server, the first inter-network data processing service and the first end may also directly perform data transmission inside the server.
In a specific implementation, the first end may establish a first IP network connection with the first inter-network data processing service, and then may send an IP network packet to the first inter-network data processing service through the established first IP network connection. After receiving the IP network data packet, the first inter-network data processing service may convert the IP network data packet into a non-IP network data packet based on a non-IP network protocol. Specifically, the first inter-network data processing service may generate a non-IP network protocol packet header, and then use the IP network data packet as a packet body, so as to generate a non-IP network data packet.
In an example, where the non-IP network is a video network, the non-IP network protocol may be a full-network transparent protocol of the video network, in which a full-network address is used in the video network, and a message may be sent to any terminal or server accessing the video network.
Step 102, the non-IP network data packet is sent to a second inter-network data processing service located in a second network area in the non-IP network, so that the second inter-network data processing service converts the non-IP network data packet into an IP network data packet, and sends the IP network data packet to a second end of the second network area based on a second IP network connection.
After generating the non-IP network data packet, the non-IP network data packet may be transmitted in the non-IP network, and the first inter-network data processing service may send the non-IP network data packet to a second inter-network data processing service located in a second network area in the non-IP network.
After receiving the non-IP network data packet, the second inter-network data processing service may convert the non-IP network data into an IP network data packet because the data is to be transmitted to the second end, which is a communication end where the application program based on the IP network protocol is located, and only the IP network data packet can be processed.
In an example, since the second inter-network data processing service and the second end are located in the same network area, the second inter-network data processing service and the second end may use an IP local area network to perform communication, and of course, if the second inter-network data processing service and the second end are located in the same server, the second inter-network data processing service and the second end may also directly perform data transmission inside the server.
After generating the IP network data packet, the second inter-network data processing service may send the IP network data packet to the second end through the established second IP network connection, and the second end may obtain the IP network data packet, and further may process the IP network data packet, to complete the cross-domain service.
In an example, the second end may also send a feedback message to the first end, where the feedback message generated by the second end may also be an IP network packet, and the transmission process may be the same as or similar to the process that the first end sends the IP network packet to the second end, and may refer to the process that the first end sends the IP network packet to the second end.
In an embodiment of the present invention, before the receiving, based on the first IP network connection, an IP network packet sent by a first end located in the first network area, the method further includes:
Receiving an IP network connection request sent by the first end; and responding to the IP network connection request, establishing a first IP network connection with the first end, and sending a request to the second inter-network data processing service so as to enable the second inter-network data processing service to establish a second IP network connection with the second end.
Before transmitting the IP network data packet, the first end may send an IP network connection request to the first inter-network data processing service, where the first inter-network data processing service establishes a first IP network connection with the first end after receiving the IP network connection request, e.g. establishes an IP network connection through a handshake interaction procedure.
Since the destination address of the IP network packet is the second end in the second network area, the first inter-network data processing service may send a request to the second inter-network data processing service located in the second network area.
After receiving the request sent by the first inter-network data processing service, the second inter-network data processing service may establish a second IP network connection with the second end, e.g., through a handshake interaction procedure.
In one embodiment of the present invention, before sending a request to a second inter-network data processing service to enable the second inter-network data processing service to establish a second IP network connection with the second end, the method further includes:
Configuring a data forwarding rule; the data forwarding rule comprises a mapping relation between a target local service port and the second inter-network data processing service and the second end.
In practical application, the first inter-network data processing service has a plurality of local service ports, and different local service ports may correspond to different communication opposite ends, so that a data forwarding rule may be preconfigured, where the data forwarding rule may include a mapping relationship between the local service ports and the communication opposite ends, that is, indicates to which communication opposite end the data received through which local service port is to be forwarded.
In an example, the mapping relationship between the destination local service port and the second inter-network data processing service, the second end includes: and mapping relation between the port number of the destination local service port and the non-IP network address of the second inter-network data processing service, the IP address of the second end and the port number.
In an embodiment of the present invention, the sending a request to the second inter-network data processing service to enable the second inter-network data processing service to establish a second IP network connection with the second end includes:
And determining a second inter-network data processing service and a second end which are mapped by the target local service port and receive the IP network connection request based on the data forwarding rule, and sending a request to the second inter-network data processing service so as to enable the second inter-network data processing service to establish a second IP network connection with the second end.
In a specific implementation, the IP network connection request sent by the first end to the first inter-network data processing service may be a request sent by the first end to a destination local service port of the first inter-network data processing service, where the first inter-network data processing service may search, in a data forwarding rule, a communication opposite end mapped by the destination local service port as a second end, where the second end is located, and the inter-network data processing service of the second network area is a second inter-network data processing service.
After determining that the opposite communication end is the second end, the first inter-network data processing service may send a request to a second inter-network data processing service of a second network area where the second end is located, where the second inter-network data processing service may establish a second IP network connection with the second end, for example, establish an IP network connection through a handshake interaction procedure.
In an example, the request may be a request based on a non-IP network protocol, where the request may carry information about the second end, such as an IP address and a port of the second end.
In one embodiment of the present invention, the first network area has a first area service and the second network area has a second area service, which may be used to communicate with other network areas, also referred to as autonomous services.
Because the first inter-network data processing service and the second inter-network data processing service are located in different network areas, the first inter-network data processing service and the second inter-network data processing service can communicate through the first area service and the second area service, specifically, the first inter-network data processing service sends a data packet to the first area service, the first area service sends the data packet to the second area service, and the second area service sends the data packet to the second inter-network data processing service.
In an example, the first area service and the second area service communicate based on a non-IP network protocol, such as a full network transparent transmission protocol of the internet of view in a case that the non-IP network is the internet of view.
In an embodiment of the present invention, because of different network access modes, different connection modes may be adopted between the inter-network data processing service and the regional service in the same network region, and the inter-network data processing service and the regional service may be connected through an IP network or a non-IP network.
For the first inter-network data processing service, the first inter-network data processing service may communicate with the first area service based on the IP network connection, that is, the first inter-network data processing service may directly send the IP network data packet to the first area service, and send the non-IP network data packet by the first area service. The communication with the first regional service may also be based on a non-IP network protocol, that is, the first inter-network data processing service may send the non-IP network data packet to the first regional service, and directly forward by the first regional service.
For the second inter-network data processing service, the second inter-network data processing service may communicate with the second area service based on the IP network connection, that is, the second inter-network data processing service may directly send the IP network data packet to the second area service, and send the non-IP network data packet out by the second area service. The second inter-network data processing service may also communicate with the second regional service based on a non-IP network protocol, that is, the second inter-network data processing service may send non-IP network data packets to the second regional service for direct forwarding by the second regional service.
For example, in the internet of view, an autonomous network provides two ways of network access:
1. The inter-network data processing service logs on a core server through a virtual terminal number (ensuring that the core server is connected to the network), and is further connected to the regional service through the core server, and the protocol conversion service, the core server and the regional service are communicated through a full-network transparent transmission protocol;
2. The inter-network data processing service is directly connected to the regional service through the autonomous user number by using TCP, communication is carried out between the protocol conversion service and the regional service through TCP, and a TCP data packet carries a data packet of a full-network transparent transmission protocol (the data packet is obtained by converting the inter-network data processing service).
In the embodiment of the invention, the IP network data packet sent by the first end of the first network area is received based on the first IP network connection, the IP network data packet is converted into the non-IP network data packet, the non-IP network data packet is sent to the second inter-network data processing service of the second network area in the non-IP network, so that the second inter-network data processing service converts the non-IP network data packet into the IP network data packet, and the IP network data packet is sent to the second end of the second network area based on the second IP network connection, thereby realizing the transmission of the IP network data packet between different network areas of the non-IP network without modifying codes of application programs based on IP network protocols, and improving the compatibility and communication convenience of the non-IP network.
Referring to fig. 2, a flowchart of steps of another method for network communication according to an embodiment of the present invention is shown, applied to a second inter-network data processing service located in a second network area in a non-IP network.
Specifically, the method comprises the following steps:
Step 201, receiving a non-IP network data packet sent by a first inter-network data processing service located in a first network area in a non-IP network; the non-IP network data packet is obtained by converting the first inter-network data processing service into an IP network data packet, and the IP network data packet is obtained by converting the first inter-network data processing service into the IP network data packet based on a first IP network connection and is received by a first end of the first network area.
When a first end in a first network area is to communicate with a second end in a second network area, that is, a cross-domain communication service is to be performed between different network areas, the first end can generate an IP network data packet based on an IP network protocol, the IP network data packet adopts an IP network protocol packet header, and a destination address of the IP network data packet is an IP address and a port of the second end.
Because the first end and the second end cannot communicate through the IP network, and the non-IP network cannot be compatible with the IP network data packet generated by the first end, the first end may send the generated IP network data packet to the first inter-network data processing service in the first network area where the first end is located.
In a specific implementation, the first end may establish a first IP network connection with the first inter-network data processing service, and then may send an IP network packet to the first inter-network data processing service through the established first IP network connection. After receiving the IP network data packet, the first inter-network data processing service may convert the IP network data packet into a non-IP network data packet based on a non-IP network protocol. Specifically, the first inter-network data processing service may generate a non-IP network protocol packet header, and then use the IP network data packet as a packet body, so as to generate a non-IP network data packet.
After generating the non-IP network data packet, the non-IP network data packet may be transmitted in the non-IP network, and the first inter-network data processing service may send the non-IP network data packet to a second inter-network data processing service located in a second network area in the non-IP network.
Step 202, converting the non-IP network data packet into an IP network data packet, and transmitting the IP network data packet to the second end of the second network area based on the second IP network connection.
After receiving the non-IP network data packet, the second inter-network data processing service may convert the non-IP network data into an IP network data packet because the data is to be transmitted to the second end, which is a communication end where the application program based on the IP network protocol is located, and only the IP network data packet can be processed.
After generating the IP network data packet, the second inter-network data processing service may send the IP network data packet to the second end through the established second IP network connection, and the second end may obtain the IP network data packet, and further may process the IP network data packet, to complete the cross-domain service.
In an embodiment of the present invention, before the sending the IP network packet to the second end of the second network area based on the second IP network connection, the method further includes:
and receiving a request sent by the first inter-network data processing service, and establishing a second IP network connection with the second end in response to the request of the first inter-network data processing service.
Before transmitting the IP network data packet, the first end may send an IP network connection request to the first inter-network data processing service, where the first inter-network data processing service establishes a first IP network connection with the first end after receiving the IP network connection request, e.g. establishes an IP network connection through a handshake interaction procedure.
Since the destination address of the IP network packet is the second end in the second network area, the first inter-network data processing service may send a request to the second inter-network data processing service located in the second network area.
After receiving the request sent by the first inter-network data processing service, the second inter-network data processing service may establish a second IP network connection with the second end, e.g., through a handshake interaction procedure.
