C. interim broadcast node server is with the live broadcast stream media program of P2P protocol function to the client transmissions request of follow-up connection on it.
In steps A, comparatively stable live broadcast stream media server can be retrieved and select to the website Control Server, sets up the relatively stable streaming media server of the live source of media of some accesses in case of necessity, removes user's blindness from and select.Certainly streaming media server is a plurality of, and live program also is a plurality of, selects by the website Control Server, or is set up separately by the website.
When setting first interim broadcast node server, as shown in Figure 2, in step B, client is landed the website by the Internet, and first sends the request of playing programme televised live to Control Server, and Control Server receives the solicited message that client sends, register the performance index of this requesting client simultaneously, its index can be the bandwidth in RAM capacity, cpu performance, client network broadband, promptly as shown in Figure 5, and R, C, D.
When Control Server detects current no interim broadcasting server, with regard to do not have selectively will this current request client be set at interim broadcast node server, and will be installed in automatically with the plug-in unit of P2P protocol conversion module on the client of this request, this client is connected on the streaming media server that includes its live broadcast stream media programme information of asking in the steps A simultaneously, the live broadcast stream media program that the request of reception is play, make, the client of this request can be on this machine the live broadcast stream media program of playing request, and it again can be with the live broadcast stream media program of P2P server capability to subsequent user conveyer belt P2P agreement.
Follow-up connection is also clicked the client of playing identical programme televised live, except that will being set to standby interim broadcast node server, all being connected to first sets under the interim broadcast node server with in the P2P transmission form sub-network, and Control Server judges whether the client of this subsequent request is the one-level sub level client 28 of interim broadcast node server, if then keep this client registers information, then abandon client registers information if not.Interim broadcast node server is by predefined bearing load requirement, when its sub-network 31 volume change amounts acquire a certain degree, can be to Control Server feedback states information, such as refreshing its information on load etc., and Control Server detects and receives this information and judge whether interim clothes are in and exceed bearing load.The register information of above-mentioned reservation one-level sub level client, mainly be the abnormality information that can detect interim broadcast node server for Control Server at any time, the improper interrupting information of particularly interim broadcast node server is so that the real-time processing of Control Server.
For preventing that interim broadcast node server from interrupting causing the interruption that other users connect under its sub-network because of connecting, Control Server need be set several vacant standby interim broadcast node servers.Standby interim broadcast node server, its setting principle and the mode of watching programme televised live are identical with interim broadcast node server, and when situation such as interruption just not occurring at interim broadcast node server, standby broadcast node server does not connect the sub level client.
The quantity of standby interim broadcast node server, general view network capacity and deciding, and when setting interim broadcast node server, and then set standby interim broadcast node server, usually standby interim broadcast node server ground quantity reaches 20 and can satisfy network demand, avoids large tracts of land to connect the appearance of interrupting storm.When standby interim broadcast node server former thereby when reducing because of withdrawing from (interruption) or changing interim broadcast node server etc. over to, the quantity of then supplying standby staging server.Be that Control Server judges that whether current standby interim broadcast node server satisfies the quantity of predetermined (being generally 20), promptly set by step among the B step b described.
The interruption of interim broadcast node server generally has two kinds of situations, and a kind of is normal interruption, and a kind of is non-normal interruption.
During normal interruption, Control Server is according to the state information of the feedback of interim broadcast node server, when detection receives the interrupting information of interim broadcast node server, Control Server will this interim broadcast node server under the sub-network transference to the standby interim broadcast node server nearby of playing identical programme televised live, promptly substitute the interim broadcast node server that interrupts by standby interim broadcast node server.
During improper interruption, Control Server is according to the immediate feedback information of the one-level sub level of interim broadcast node server, when detection receives the interrupting information of interim broadcast node server, Control Server with sub-network transference under the interim broadcast node server to the standby interim broadcast node server nearby of playing identical programme televised live.
The sub level client that connects in the sub-network of certain interim broadcast node server in the network withdraws from, when staging server no longer includes client and is connected with it, when promptly this interim broadcast node server has been in vacant state, if the quantity backlog demand of current standby interim broadcast node server, then keep this interim broadcast node server, as standby interim broadcast node server; If the quantity of current standby interim broadcast node server meets the demands, then cancel the setting of this interim broadcast node server, transfer general requesting client to, and select an interim broadcast node server or a standby interim broadcast node server connection of playing identical programme televised live for it.
The present invention adopts that dynamic broadcast node server mode replaces fixing, the dedicated broadcast node server, make full use of Internet resources, reduce hardware investment, simultaneously the dynamic broadcast node technology is applied to P2P live on, utilized the resource-sharing of P2P principle better.
