As shown in Figure 2, in the embodiment of the present invention, Streaming Media signaling method flow chart, its concrete processing procedure is as follows:
Step 21, in the P2P stream media system, the Tracker server receives the Streaming Media signaling that first terminal sends, and in this Streaming Media signaling, carries the terminal identification information of signaling type information and the second terminal;
Wherein, the terminal identification information of the second terminal that the Tracker server receives can be, but not limited to the identity information into address information or this second terminal of this second terminal, the address information of terminal comprises IP address and the port numbers of this terminal, and the identity information of terminal can be the unique identification code of this terminal.
In the embodiment of the present invention, the first terminal Streaming Media signaling of other-end of giving to be sent can be, but not limited to as following signaling:
Demand signalling is set up in session connection, session connection is set up and confirmed that demand signalling is removed in signaling, session connection or the confirmation signaling is removed in session connection.
At the Tracker server, receive before session connection that first terminal sends sets up demand signalling, can further include following step:
The terminal iidentification that receives the first terminal transmission obtains demand signalling, this terminal iidentification obtains in demand signalling the Resource Block identification information of the streaming media resource piece that carries the first terminal acquisition request, then according to the Resource Block identification information that receives, in the corresponding relation of Resource Block identification information and terminal identification information, search the terminal identification information of the terminal that stores this streaming media resource piece, the terminal identification information that finds is sent to first terminal.
if Y the Resource Block of first terminal acquisition request film X, the Resource Block identification information of the streaming media resource piece of first terminal acquisition request can be, but not limited to as (Movie X so, Chunk Y), first terminal sends and carries (Movie X to the Tracker server, Chunk Y) terminal iidentification obtains demand signalling, because each terminal in the P2P stream media system is all regularly issued the Resource Block information of the streaming media resource piece of self storing to the Tracker server, therefore in the Tracker server, just store the corresponding relation of Resource Block identification information and terminal identification information, the Tracker server is in above-mentioned corresponding relation, search the terminal identification information of the terminal of Y the Resource Block that stores film X, and each terminal identification information composition Peer List that will find sends to first terminal.
Wherein, for prevent first terminal directly and Peer List in terminal directly communicate, the embodiment of the present invention proposes, the terminal identification information that comprises in the Peer List that the Tracker server sends is the identity information of each terminal, rather than address information, therefore first terminal can not be directly and each terminal communicate, signaling must be passed through to the forwarding of Tracker server.
Terminal A can select arbitrarily a terminal to carry out transfer of data in Peer List, in addition, in order to make terminal A select the high terminal of transmission rate to carry out transfer of data, the Tracker server can also comprise each terminal transmission speed in sending to the Peer List of terminal A, terminal A, after receiving Peer List, selects the high terminal of transmission rate that the data of streaming media resource piece are provided for terminal A.
If the terminal identification information of the second terminal that the Tracker server receives is the address information of the second terminal, the Tracker server can, directly according to the address information of the second terminal, be transmitted to the second terminal by the Streaming Media signaling that receives so;
if the terminal identification information of the second terminal that the Tracker server receives is the identity information of the second terminal, the Tracker server need to first be determined the address information of the second terminal so, because terminal can periodically be notified the server to Tracker by the IP address of self and port, in the Tracker server, just store the address information of each terminal and the corresponding relation of identity information, therefore the Tracker server can be according to the identity information of the second terminal that receives, in above-mentioned corresponding relation, search the address information of the second terminal, again according to the address information that finds, the Streaming Media signaling that receives is transmitted to the second terminal.
first terminal comprises three parts to the Streaming Media signaling that the Tracker server sends, transmission head, heading and data segment, wherein in transmission head, comprise source node IP address and port (being IP address and the port of first terminal) and destination node IP address and port (being IP address and the port of Tracker server), in heading, comprise signaling type information, the terminal identification information of first terminal, the terminal identification information of the second terminal etc., the Resource Block identification information that comprises the streaming media resource piece of first terminal acquisition request in data segment, the address information of first terminal, the address information of Tracker server etc.
The Tracker server is according to the address information that finds, and the process that the Streaming Media signaling that receives is transmitted to the second terminal can be, but not limited to as following:
The address information of the first terminal that comprises in the data segment of the Streaming Media signaling that at first will receive, replace with the address information of Tracker server, and the address information of the Tracker server that comprises in the data segment of the Streaming Media signaling that will receive, replace with the address information of the second terminal that finds, then will be transmitted to the second terminal through the Streaming Media signaling that address information is replaced after processing.
Before Tracker server forwarding stream media signaling, by the source node IP address of the transmission head of the Streaming Media signaling that receives and IP address and the port that port replaces with self, then the IP address of destination node and port are replaced with to IP address and the port of the second terminal.
because some terminal in the P2P stream media system may be in LAN, therefore other-end or server need to communicate according to the private net address of this terminal, and in prior art, the Tracker server is in the Peer List of the terminal transmission of acquisition request streaming media resource piece, the address information of each terminal generally is the public network address information of terminal, if to corresponding terminal, send the Streaming Media signaling according to public network address information, may there is the failed problem that sends, and in embodiment of the present invention technical scheme, all Streaming Media signalings of terminal room forward by the Tracker server, and the Tracker server stores has the public network IP address of each terminal and the corresponding relation of private network IP address, therefore what the Tracker server can be by the success of Streaming Media signaling sends to the purpose terminal.
In addition, the Tracker server also, further according to the Streaming Media signaling that forwards, is monitored the transfer of data between first terminal and the second terminal, can be, but not limited to comprise following several monitoring mode:
To the data traffic of transmitting between first terminal and the second terminal add up, to transmission between first terminal and the second terminal during data, the average transmission rate of the second terminal is added up or the video-on-demand times of the streaming media resource piece of the data transmitted between carrying first terminal and the second terminal is added up.
