RTP Introduction

This introduction is meant for beginners. This beginners' made easy tutorial is to give a brief introduction to RTP before one ventures into the long RFC documents. However, if you are a veteran please go through this short tutorial and suggest modifications.

What is RTP?

Real-time Transfer Protocol (RTP) provides end-to-end delivery services for data (such as interactive audio and video) with real-time characteristics.
