Overview

What is POX?

POX is a Python-based framework for developing software-defined networking (SDN) control applications, particularly useful for creating and managing OpenFlow controllers. It provides developers with the tools necessary to build custom network management solutions.

Key differentiator

POX stands out as a highly flexible and customizable OpenFlow controller framework, ideal for developers who require extensive control over their network management solutions.

Strengths & Weaknesses

↑ Strengths

Flexible and extensible SDN control frameworkmedium

Support for OpenFlow protocol versions 1.0 to 1.5medium

Modular design allowing easy extension and customizationmedium

↓ Weaknesses

Steep learning curve for non-Python developershigh

API requires Python-specific patterns, TypeScript SDK is community-maintained

Frequent breaking changes between versionsmedium

v0.1 to v0.2 migration required rewriting chain definitions

Limited support for newer OpenFlow protocol versions (beyond 1.5)high

POX primarily supports OpenFlow up to version 1.5, missing out on features in later versions

Small and less active communitymedium

GitHub activity shows fewer contributors compared to other SDN frameworks like Ryu or Floodlight
