4. Communications and Protocols
4.1. Overview
The elements that compose the architecture interact with each other using:
• HTTP(S) for all web interaction and across server's interaction.
• Socket IP across the modules within the same server
The High-level communication stack is summarized by the following schema:
Figure 4 HAS Communication Stack
The full schema of communications and protocols used is shown below:

(1) Port number may vary depending on IT policies. Given values are the default one.
(2) Recommended values for optimal performance
(3) The Dynamic port range used between HAS Server and the module is used only within the Server (localhost). No communication across servers is done with this port range.
