3.Specific requirements, covering functional, non-functional and interface requirements

• document external interfaces,
• describe system functionality and performance
• specify logical database requirements,
• design constraints,
• emergent system properties and quality characteristics.

3.1 Requirement X.Y.Z (in Structured Natural Language)

Function: To dynamically updates the public IP address of a host on a DNS server whenever the host is mobile and is located in a foreign network

Description: Implement an open source dynamic DNS server and demon to run on various device (PC, laptop, Android tablet etc)

Inputs: Dynamic IPs

Source: Users who host their websites or depositories behind a router/modem with dynamic IP

Outputs: Dynamic DNS updates

Destination: Open DynDNS server

Action:

• Open DynDNS client must notify OpenDynDNS server whenever it detects a change in IP adress on the host
• Open DynDNS server updates shall not be modified by non-recognizable device

Non functional requirements:

• Open DynDNS client may be run on various device such as a laptop, PC or an Android tablet.

Pre-condition:

• Hardware

- Raspberry PI - Android tablette (Nexus 10) - 2 machine running on Linux

• Software

- Ubuntu desktop - MQTT sensors - Flask API and Flask REST-ful - Kivy - Liclipse for Python

Post-condition:

• User must be situated in a foreign network with different public IP address before launching the daemon

Side-effects:
