1. method that the control flows media data distributes on the marginal flow media server, in the streaming media service distributed structure/architecture that is applied to be formed by terminal use, Centroid device and connected center streaming media server, different fringe node device and connected marginal flow media server, it is characterized in that, may further comprise the steps:

  • (1) during initial condition,, in the streaming media server of described center, select part or full content to be published on the marginal flow media server that is connected with different fringe node devices by described Centroid device;

    (2) described marginal flow media server carries out term of validity judgement to the content that receives, if the content term of validity is also not yet due, then described marginal flow media server is preserved this content, and writes down the relevant parameter information of this content;

    If the content term of validity expires, then described marginal flow media server is deleted this content;

    (3) as described terminal use during to certain fringe node device request content, the marginal flow media server that is connected with this fringe node device judges whether certain content of the request of preserving, if there is this content, then this marginal flow media server is issued the terminal use with request content;

    If there is no this content, then this marginal flow media server is initiated this content of active request by coupled fringe node device to Centroid device or other fringe node devices, issues the terminal use again after obtaining this content;

    (4) take when surpassing certain threshold value when disk space in the described marginal flow media server, then described marginal flow media server is according to the relevant parameter information deletion partial content of recorded content.
