Study Guide

Objective

The goal of this workshop is to introduce the students to the concepts and techniques for programming a network device. Upon completion of the workshop, students will be able to:
- Understand the value, set-up and use of software concepts and tools relevant to network programmability (Python scripting, Git, JSON, Postman, APIs).
- Describe a different approach to software-defined networking (SDN), including central application policy control.
- Create simple applications in Python with REST APIs.
- Use the Cisco DevNet Sandbox to interact with programmable devices using real-world APIs on Cisco APIC-EM programmable controllers.
- Create a variety of programs to interact with the Cisco APIC-EM APIs.

Content scheduling

The goal of this course is to introduce the student to the programming related concepts and techniques often needed in the field of data networks and information security.

Upon completion of this course, students will be able to write small Python scripts to:
-Parse different kinds of data (JSON, log data etc.)
-Connect and query a database
-Query an external API for data and build a simple REST API of their own

The contents of the course:
-JSON format
-Using basic Python data structures to store data
-Parsing data in Python
-Basics of databases - concepts of relational and non-relational databases
-Querying databases with Python
-Concept of an API
-Querying an API with Python
-Building your own RESTful API
-Command line arguments and piping content to a Python script
-Accessing OS from scripts

Further information
