There is lack of clear description of QoS in the current web service described by OWL-S,which make it hard to get the optimal service.The QoS module to the web service discovery architecture is introduced,and a web service discovery architecture SWSDM-QoS that support QoS constraint is advanced.This model supports web service publish with QoS information,web service search with QoS-constrainted and feedback with QoS.And a web service selection algorithm based on QoS constraint is also provided.A prototype based on Microsoft.NET is implemented.
