WHAT ARE WE GOING TO TALK ABOUT? NEW FEATURES IN AOS 7. 3. 4 DESCRIPTION Event-Action Triggers execution of a python program when the specified trap occurs Python Interpreter Enables execution of Python programs RESTful API (Since 7. 3. 2) Web Services management interface to access the MIB as well as CLI in JSON or XML formats.

INTERNAL PYTHON • Internal Python program under AOS on the Omni. Switch • Three ways to execute Python Automatically, as an AOS “event-action” when a TRAP occurs Interactively, from the AOS console In a file executed by command from the AOS console • AOS Python includes standard Python 3 packages for OS access and issuing AOS commands AOS 7. 3. 4 Python script running on Omni. Switch Customer-written Python program Python 3 interpreter and standard Python packages are built into AOS 5 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED.

EXTERNAL PYTHON THROUGH RESTFUL API • External Python scripts run on a PC external to the Omni. Switch Requires python 2 or python 3 interpreter on PC/Linux/Mac. Easy to install from python. org. Python script on PC connects to AOS using HTTP/HTTPS and the AOS RESTful APIs. Sample Python code and libraries are available to demonstrate access to MIB variables in one or more AOS 7. 3. 4 switches. Sample library returns results in an easy-to-handle Python “dictionary” object Customer-written Python program Python script running on PC/Linux/Mac AOS 7. 3. 4 MIB variables accessible via Web Services Sample AOS REST library Python 2 or Python 3 interpreter/Py. Pi packages Web Services via HTTP/HTTPS 6 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. ALCATEL-LUCENT — INTERNAL PROPRIETARY — USE PURSUANT TO COMPANY INSTRUCTION

INTERNAL + EXTERNAL • Combine internal python scripts with external RESTful API • A python script can execute on the local switch and on the remote switch through the RESTful API • Can execute interactively from console, from a file or when a TRAP occurs.

SCENARIO AND DEMO

DEMO SCENARIO • The Microwave link provides high bandwidth at low cost however is susceptible to fading etc in bad weather. Central Site • The Telco link provides moderate bandwidth and high quality but the cost is high. • In normal circumstances, Internet traffic will use the Microwave link whilst Corporate traffic including VOIP will use the Telco link. • But when the quality of the Microwave link degrades, a Python App will divert Internet traffic to the Telco link and set a 1 Mbps bandwidth cap. Remote Site Corporate Traffic Internet Traffic • Internet traffic will automatically revert to using the Microwave link when the quality becomes acceptable. 9 COPYRIGHT © 2014 ALCATEL-LUCENT.
