On a method of reliable delivery and data source verification within a client–server interaction over an open communication channel

Two models of client–server interaction are considered: a model to describe reliable data delivery over an open channel and a model to describe data source verification. The models are formulated based on a set of rules to resolve the conflicts when several clients are connecting to one server. A computer-appliance is suggested for testing the functionality of the models either allowing several connections to the server from multiple clients or blocking connections from multiple clients.
