Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, for two terminals that belong in the different private networks, because their IP address can't be discerned on public network, serve as public servicer so increase a main frame that possesses public IP, as shown in Figure 1, wherein, initiate client and destination client and be the terminal that belongs under private network 1 and the private network 2, NAT1 is the server host of the band fire compartment wall of private network 1, NAT2 is the server host of the band fire compartment wall of private network 2, before initiating to set up the passage of transmission data between client and destination client, these two terminals all will realize the transmission of information by public servicer, in case passage is set up successfully, these two terminals just can realize point-to-point data communication by NAT separately.
Fig. 2 shows that the embodiment of the invention provides can firewall-penetrating the sequential flow process of multimedia network communication method, details are as follows:
1, at first initiates client and destination client and need send log messages, be used for registration to public servicer.
Initiate client and destination client and open three ports separately: control command port (as: cmdPort, Socket is cmdSockfd), transmit FPDP (as: sendPort, Socket is sendSockfd), receive FPDP (as: recvPort, Socket are recvSockfd).
When three ports all when public servicer sends log-in command, NAT server is separately passed through in the capital, therefore IP and port can be mapped to the IP and three different port numbers of corresponding NAT at the public servicer place, since public servicer can with each NAT server communication, so mailing to the data of issuing these three ports on the NAT server all can be received by client, certainly public servicer also can be noted these three through the port numbers after the NAT server mappings, has so just finished the registered task of each client.At this moment, initiating client can communicate by letter with public servicer with the destination client.
Directly send information to the destination client if 2 initiate client wants, he can obtain the public network address of destination client from public servicer there so.Concrete acquisition methods is as follows:
Initiate client and send a specific request to public servicer, as: the address information of obtaining all clients, public servicer will return to the initiation client to all client-side informations of registering so, initiates client like this and has just known the address information of destination client.
If initiate client and directly send information to the destination client 3 this moment, message can not be received in the destination client, because if send information like this, NAT2 can abandon this information (because such information is self-invited, for safety, most of NAT can carry out and abandon action).However, initiating client still wants directly to send information to the destination client earlier, the purpose of this step is the transmission record of initiating client in order to stay in NAT1, includes the information (comprising address, port etc.) of destination client in this recorded content.
4, next, send request by initiating client to public servicer, the request public servicer is forwarded to the destination client with information, also includes the address information of destination client in this solicited message.
5, public servicer is by resolving solicited message, know and initiate the information content that client sends, and the address information of destination client, can directly send information then to the destination client, include the address information (comprising IP and port) of initiating client in this information, the address information of initiating client also can be known in the destination client like this.
6, after the solicited message of public servicer forwarding is received in the destination client, its port can initiatively send information to the corresponding port of initiating client, for example, include the control command port of initiating client in the solicited message of receiving, then the control command port of destination client will initiatively send information to the control command port of initiating client; Include the transmission FPDP of initiating client in the solicited message of receiving, then the reception FPDP of destination client will initiatively send information to the transmission FPDP of initiating client; Include the reception FPDP of initiating client in the solicited message of receiving, then the transmission FPDP of destination client will initiatively send information to the reception FPDP of initiating client.
7, since before had the client of initiation among the NAT1 and sent recording of information to the destination client, information for the transmission of above-mentioned destination client, NAT1 can not abandon this information, but send to the initiation client, initiate so just to have set up communication line between the corresponding port of client and destination client, thereby can carry out the communication of multimedia messagess such as audio frequency and video, can not tackled by NAT fire compartment wall separately again.
In embodiments of the present invention, when initiating successfully to have set up 2 communication lines that can transmit audio/video data between client and the destination client, then can satisfy and initiate the mutual simultaneously audio/video data that sends of client and destination client, can realize dialogue function, Voice ﹠ Video data sharing communication line, the transmission of staggering the time.Simultaneously, can carry out real-time control and management to the communication lines of two transmission audio/video datas by the passage between the control command port of initiating client and destination client, as: stop/beginning transmitting data, real-time report switching between current state and operation, user or the like to the other side or system oneself.
Based on above principle method, can expand to a multimedia communication of initiating client to a plurality of destination clients, to communicate by letter with 2 destination clients is example, only need to set up communication line with the 2nd destination client and get final product initiating to open again on the client one group (3 ports), certainly this need be guaranteed with the network bandwidth be prerequisite.
Carry out multimedia communication between a plurality of clients for having, manage current all online client states by public servicer.In embodiments of the present invention, can regularly send pulse information by public servicer to each registered client, after receiving, client must return an acknowledgement command, if public servicer is not all received acknowledgement command under the situation that sends repeatedly (for example 3 times), prove that then this client is not online, just the deletion from the online client tabulation of this client; Otherwise prove that this client user is online.This state-detection process is used the control command passage, can not influence the transmission of multi-medium data.
The multimedia network communication method of the energy firewall-penetrating that the embodiment of the invention provides has the main frame of public IP as server by utilization, finish the foundation of the point-to-point communication circuit of the terminal room under the different private networks, have management function simultaneously concurrently to terminal, the multimedia realtime communication problem of two terminal rooms under different private networks be can well solve, the real-time Transmission of remote monitoring product, long-range audio frequency and video and Play System can be used for and other relates to a lot of application scenarios that penetrate network firewall.
