Provided are a
Web service Quality of Service (QoS) distributed measurement
system and method. The
Web service quality distributed measurement
system is provided with a center node and a plurality of measurement nodes. The
Web service QoS distributed measurement method is characterized in that
network coordinates of user hosts, the plurality of measurement nodes and Web service deployment hosts, namely service deployment nodes, in an abstract network coordinate
system are respectively calculated by aid of the network
positioning technology according to a Web service QoS
estimation model, and similarity of the user hosts and the measurement nodes is calculated so as to estimate QoS attribute values capable of being obtained by users. The Web service QoS distributed measurement method and system can fast and accurately estimate Web service QoS capable of being obtained by the user sides in different regions and / or different network environments, and the Web service QoS includes
response time and reliability. The Web service QoS distributed measurement method has strong instantaneity and does not depend on historical QoS data of the users, dost not add additional load to the users, and is transparent in the
estimation process. The Web service QoS distributed measurement method and system are characterized in that the network system is mapped into the multi-dimensional coordinate system,
response time and reliability of Web service and capable of being obtained by the user sides can be estimated by combining similarity of the user hosts and the measurement nodes, and true and credible data can be obtained.
