Mastering Python Networking

Overview of this book

This book begins with a review of the TCP/ IP protocol suite and a refresher of the core elements of the Python language. Next, you will start using Python and supported libraries to automate network tasks from the current major network vendors. We will look at automating traditional network devices based on the command-line interface, as well as newer devices with API support, with hands-on labs. We will then learn the concepts and practical use cases of the Ansible framework in order to achieve your network goals. We will then move on to using Python for DevOps, starting with using open source tools to test, secure, and analyze your network. Then, we will focus on network monitoring and visualization. We will learn how to retrieve network information using a polling mechanism, ?ow-based monitoring, and visualizing the data programmatically. Next, we will learn how to use the Python framework to build your own customized network web services. In the last module, you will use Python for SDN, where you will use a Python-based controller with OpenFlow in a hands-on lab to learn its concepts and applications. We will compare and contrast OpenFlow, OpenStack, OpenDaylight, and NFV. Finally, you will use everything you’ve learned in the book to construct a migration plan to go from a legacy to a scalable SDN-based network.

In this chapter, we took a grand tour of the open source automation framework of Ansible. Unlike Pexpect-based and API-driven network automation scripts, Ansible provides a higher layer abstraction called the playbook to automate your network devices.

Ansible was originally constructed to manage servers and was later extended to network devices; therefore we took a look at a server example. Then, we compared and contrasted the differences when it came to network management playbooks. Later, we looked at the example playbooks for Cisco IOS, Juniper JUNOS, and Arista EOS devices.

In the next chapter, we will leverage the knowledge we gained in this chapter and start to look at some of the more advanced features of Ansible.
