EXAMPLE III
Referring to fig. 7, a flowchart illustrating steps of message transmission methods according to a third embodiment of the present invention is shown.
The message transmission method of the embodiment of the invention can comprise the following steps:
in step 701, the gateway device receives terminal information reported by the th terminal.
The terminal information may include a video network MAC address and a video network number, and thus, the terminal information reported by the st terminal may include a video network MAC address of the st terminal and a video network number of the th terminal.
Step 702, after finding a second terminal waiting for establishment of a video networking tunnel with the th terminal, the gateway device obtains th tunnel information corresponding to the th terminal and second tunnel information corresponding to the second terminal, issues the th tunnel information to the th terminal, and issues the second tunnel information to the second terminal.
After receiving the terminal information reported by the th terminal, the gateway device searches whether a second terminal waiting for establishing a video networking tunnel with the th terminal exists.
In alternative embodiments, the gateway device may set a table (e.g., a Hash chain table) for storing terminal information and tunnel information (possibly or more tunnel information) of each terminal, and after receiving the terminal information reported by the th terminal, the gateway device may look up whether terminal information of other terminals already exists in the table, if so, take the other terminal as a second terminal (possibly or more second terminals) waiting for establishing a video networking tunnel with the th terminal, and if not, store the terminal information reported by the th terminal in the table, and continue to wait for the terminal information reported by the other terminals.
After finding out the second terminal waiting for establishing the video networking tunnel with the th terminal, the gateway device obtains the th tunnel information corresponding to the th terminal and the second tunnel information corresponding to the second terminal.
In alternative embodiments, the process of obtaining the th tunnel information corresponding to the th terminal and the second tunnel information corresponding to the second terminal may include steps a1 to A3:
step A1, allocating a corresponding th video network sub-number associated with the second terminal to the th terminal, allocating a corresponding second video network sub-number associated with the th terminal to the second terminal, and allocating a call role to the th terminal and the second terminal.
Selecting video network sub-numbers which are not allocated to the terminal from a plurality of preset video network sub-numbers to serve as video network sub-numbers which correspond to the terminal and are associated with the second terminal when the video network sub-numbers are allocated, selecting video network sub-numbers which are not allocated to the second terminal from the plurality of preset video network sub-numbers to serve as second video network sub-numbers which correspond to the terminal and are associated with the second terminal;
the number of the preset video networking sub-numbers can be set to be any suitable number according to the performance of the terminal, and the embodiment does not limit the number, for example, 200 video networking sub-numbers can be set, the video networking sub-numbers can be 0 to 199, and the like.
When the call role is allocated, allocating the call role as a calling party to the th terminal, allocating the call role as a called party to the current second terminal, and allocating the call role of each second terminal as a called party.
Step a2, obtaining the terminal information of the second terminal, the second video network sub-number corresponding to the second terminal and associated with the terminal, the video network sub-number corresponding to the terminal and associated with the second terminal, and the call role of the terminal, as the tunnel information corresponding to the terminal and corresponding to the second terminal.
Step A3, obtaining the terminal information of the terminal, the th video network sub-number corresponding to the th terminal and associated with the second terminal, the second video network sub-number corresponding to the second terminal and associated with the th terminal, and the call role of the second terminal, as the second tunnel information corresponding to the second terminal.
After acquiring the tunnel information corresponding to the th terminal and the second tunnel information corresponding to the second terminal, the gateway device issues the th tunnel information to the th terminal, and issues the second tunnel information to the second terminal.
In optional embodiments, for each second terminal, the gateway device issues the th tunnel information corresponding to the current second terminal to the th terminal, and issues the second tunnel information corresponding to the current second terminal.
Step 703, the th terminal sends a call request to the second terminal, and after the call is successful, establishes the internet-of-video tunnel between the th terminal and the second terminal according to the th tunnel information and the second tunnel information corresponding to the second terminal.
After the th terminal receives the th tunnel information, the th terminal sends a call request to the second terminal because the th terminal is the calling party.
The process that the terminal sends the call request to the second terminal can comprise that the terminal sends the call request carrying the video networking number of the second terminal to the video networking server after determining that the own call role is the calling, the video networking server can determine the second terminal according to the video networking number of the second terminal and forward the call request to the second terminal, and the terminal succeeds in calling after the second terminal accepts the call.
after the call is successful, because the 0 th tunnel information corresponding to the th terminal includes the video network MAC address of the second terminal, the video network number of the second terminal, the second video network sub-number corresponding to the second terminal, and the th video network sub-number corresponding to the 1 th terminal, and the second tunnel information corresponding to the second terminal includes the video network MAC address of the th terminal, the video network number of the th terminal, the th video network sub-number corresponding to the th terminal, and the second video network sub-number corresponding to the second terminal, and the video network sub-numbers correspond to the ports on the terminals, the video network tunnel between the th terminal and the second terminal can be established according to the th tunnel information corresponding to the th terminal and the second tunnel information corresponding to the second terminal.
Step 704, after the th terminal obtains the video networking message to be transmitted to the second terminal, the destination video networking MAC address in the video networking message is replaced by the video networking MAC address of the second terminal, and the video networking tunnel is used to transmit the replaced video networking message to the second terminal.
After the video network tunnel between the th terminal and the second terminal is successfully established, the th terminal and the second terminal can interact video network messages through the video network tunnel.
The internet message is driven by the system, the video network message is firstly uploaded to a socket to a kernel mode protocol stack, the protocol stack finds a data packet in a corresponding port and sends the data packet out in a routing or bridge forwarding mode, the data is sent to the kernel mode through the socket, and the kernel mode sends the data out through the protocol stack.
Therefore, the terminal may obtain the internet packet from the protocol stack, and then encapsulate the internet packet into the video networking packet in an original manner, but because the video networking packet in the original manner is to be forwarded by the video networking server, a destination video networking MAC address in the video networking packet is the video networking MAC address of the video networking server at this time.
When the replaced video network message is transmitted by using the video network tunnel, the th terminal transmits the replaced video network message to a port corresponding to the second video network sub-number on the second terminal through a port corresponding to the th video network sub-number on the th terminal according to the video network MAC address of the second terminal, the video network number of the second terminal and the second video network sub-number.
The embodiment of the invention is provided with the gateway equipment, the video network tunnel between the th terminal and the second terminal can be established through the gateway equipment, and the video network messages transmitted between the th terminal and the second terminal can be directly transmitted through the video network tunnel without being forwarded by the video network server, so that the transmission efficiency of the video network messages can be improved, the video network messages are not influenced by the performance of the video network server and the bandwidth of a network port, and the load of the video network server is reduced.
