The network layer to be studied in this and the next unit provides host-to-host communication services to process-to-process communication services. It is the network layer that makes data flow correctly and efficiently across the entire Internet. This network layer is so important in the TCP/IP network protocol stack that it is studied over the course of two units. Unit 4 deals with the data plane of the network layer and illustrates how a transport layer segment is packed into packets for transmission from origin to destination. Unit 4 also covers IP forwarding, a basic function that every host and router on a network must have.</p> +</div> +<div class="col-12"><footer><!-- <p>© [Client] [Year]</p> --> <!-- <p><img src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/_assets/img/logo.png" alt="logo"></p> --></footer></div> +</div> +</div> +<p> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/jquery/jquery-3.4.1.min.js"> + </script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/popper-js/popper.min.js"> + </script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/thirdpartylib/bootstrap-4.3.1/js/bootstrap.min.js"> + </script> +</p> +<!-- Template JavaScript --> +<p> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/js/scripts.min.js"></script> +<script src="/shared/LCS_HTML_Templates/Athabasca_Template_2021/Template_Files/sample_pages/../../_assets/js/custom.js"></script> +</p></body></html>
