The SDPBloom automatic discovery algorithm can not judge Quality of Service(QoS)compatibility of endpoints in the participants discovery phase in advance,and it makes probably a large number of QoS incompatible endpoints information on the each node and the network,which consumes too much memory and network resources. To solve this problem,this paper proposes an automatic discovery algorithm based on Service Ability Vector(SAV),which can judge whether the topic name and type of endpoints are matched and QoS compatibility by the Bloom Filter Vector(BFV)and SAV to reduce unnecessary information transmission and storage. Experimental results show that the algorithm has lower memory resource and network transmission consumption than SDP_ADA algorithm and SDPBloom algorithm.
