The attached sample chapter from Distributed Network Systems: From Concepts to Implementations (Jia, W. and Zhou, W.,2005) is designed to introduce the client-server model and its role in the development of distributed network systems.
The chapter discusses the cooperation between clients and servers/group servers in distributed network systems, and addresses extensions to the client-server model. Service discovery, which is of crucial importance for achieving transparency in distributed network systems, is also elaborated in this chapter.
