===== Communications Model =====

The **Communications Model** underlying the network [[ddsf:public:guidebook:06_append:glossary:m:midware|middleware]] is the most important factor in how applications communicate. The communications model impacts the [[ddsf:public:guidebook:06_append:glossary:p:performance|performance]], the ease to accomplish different communication transactions, the nature of detecting errors, and the robustness to different error conditions. Unfortunately, there is no “one size fits all” approach to [[ddsf:public:guidebook:06_append:glossary:d:dapp|distributed applications]]. Different communications models are better suited to handle different classes of application domains.

We commonly discuss three main types of network communications models:

  * [[ddsf:public:guidebook:06_append:glossary:p:point-to-point]]
  * [[ddsf:public:guidebook:06_append:glossary:c:client-server]]
  * [[ddsf:public:guidebook:06_append:glossary:p:publish-subscribe]]
