In an open Web service market, a large number of services may spread in different areas and belong to different business organizations. How to manage QoS (Quality of Service) and provide a reliable environment for users to employ services becomes a crucial problem in Web service research. In literature, QoS management is conducted by centralized brokers, which is able to manage services in a certain domain. However, Web services from different management domains are supposed to interact with each other, but the cross-domain QoS management problem has not been substantially studied yet. In this paper, we propose a distributed QoS management architecture for Web services, called Q-Peer. Q-Peer is the supporting platform for our previously proposed distributed management approaches. Q-Peer is formed by a number of QoS brokers where each broker manages a set of Web services. Cross-domain management capabilities are performed by coordinating of peers. The management capabilities are deployed on peers as application modules. The Q-Peer architecture is extensible in term of management domain as well as management capability.
