Embedded TCP/IP Networking Basics

Introduction

The page links below aim to provide a brief introduction to the concepts and terminology of TCP/IP and UDP/IP networks, and how they relate to the FreeRTOS+TCP implementation. The pages do nothing more than provide a top level overview of subjects that could be comprehensive topics in their own right, so links to external references are also provided where appropriate.

Do not be put off by the apparent complexity of the subject. FreeRTOS+TCP takes care of implementing the protocols. FreeRTOS+TCP users only need to know enough to understand the FreeRTOS+TCP configuration options, and how to use the standard Berkeley sockets interface to send and receive data. A FreeRTOS+TCP networking tutorial with simple worked examples and an API reference are provided on this website.

The following links provide a glossary of networking terminology, and are best read in order:
