Abstract:

Locating suitable services within a dynamic distributed system is a computationally intensive process, with no guarantee of quality and suitability of the discovered services. This is especially true for transient services, i.e. services which are likely to exist over short time frames. A significant effort has already been spent on developing distributed registry systems – such as the UDDI registry in Web services – to enable services to be published, and subsequently discovered. Regardless of the type of registry being used, it is nevertheless important to categorise services based on their particular properties – a process that should also aid the subsequent discovery of the service. A mechanism for grouping services based on a particular set of properties is investigated here – leading to the formation of service communities. Each such community is based on the existence of common parameter values being shared by members of the community. The structure of such a community is described, and a particular type of community established on the basis of Quality of Service properties is subsequently developed.
