Implementing Multiparty Interactions on a Network ComputerRafael Corchuelo, David Ruiz, Miguel Toro, Antonio RuizClassical client/server interaction primitives such as remote procedure call or rendezvous} are not adequate when we need to describe the behavior of three or more processes that need to collaborate simultaneously in order to solve a problem. Multiparty interactions are the key to describe these problems, and there are several languages that use them for the description of reactive systems. In this paper, we show and compare two different fair implementations of this mechanism and also outline the research we are carrying out in an effort to improve them.
