Abstract: According to the application environment of embedded video-phone，this paper analyzed conference-model based on P2P and high-discrete addresses condition.Aiming at the application level multicast problem about the distributed-conference model，an evaluation expression with constraints of bandwidth，delay and process cost is formed.Complying with the strategy that excellence gene is more derive，a kind of genetic algorithm of multicast with degree and delay constraints，which arises from FMPH and SPH algorithm result，is proposed.The simulations prove that the algorithm has nice stability and nice astringency.It provides an optimal multicast routing solution for the conference-model based on P2P.The problems about mutability of bandwidth and delay are still pending.
