Successive to a preceding study about Service Discovery, this thesis covers the topics Service Description and Service Access. Starting with an analysis and comparison of existing technologies, a new protocol for the service access was developed and an operating
environment, capable of accessing services of any type was programmed. Thereby emphasis is placed on high scalability, extensibility, modularity and comprehensive documentation, to provide easy association with existing or future works. The first part deals with the various versions of Service Descriptions, followed by a description of the service access methods and concluding with a comprising comparison. All technologies or protocols qualified for Service Discovery and Access discovered
during this diploma thesis are discussed. The main part comprises the software implementation which was written in Java, including
a comprehensive documentation containing, among others, the protocol specification, software architecture, an user guide and proposals for advancements.
