CLIENT AND SERVER HAVING ENHANCED PERFORMANCE USING SELF-SYNCHRONIZATION PROCESS OF CLIENT GROUP

摘要

PURPOSE: A client and a server are provided to enhance a performance improvement capable of being obtained through an SIS(Server Independent Synchronize) group creation and make a plurality of information be exchanged through a direct communication of clients besides a synchronization process by making a reconfiguration of an SIS group free according to contents of a service. CONSTITUTION: Prerequisites adapted to a performance improvement necessary for an SIS group creation and a client expected for a performance improvement are provided by constituting a child client/server group in a client/server model. A processing condition makes a member client secede or participate freely in an SIS group maintenance and makes an SIS group reconfiguration of the next agent be synchronized at a client trouble and makes a service be connected freely. A server performer secedes an SIS group explicitly in an SIS group reconfiguration and a communication is interrupted caused by a communication trouble. Thus, a performance improvement is obtained analytically from a server internal load and a network load of a local network of the server.
