Preface

A distributed system is a collection of autonomous units able to make decisions locally. Through cooperation, these distributed units can solve global computational problems together. This book is dedicated to one of the most fundamental processes in operating a distributed system, referred to as the rendezvous process. Rendezvous takes place when the external ports belonging to two neighboring units become connected, and they can communicate and exchange information through this connection. There are five dimensions in which to define an instance of rendezvous. First of all, the a
