Il possède les mêmes composants de base qu’un ordinateur de bureau standard. Il est doté d’un processeur (UC), de mémoire, d’un système de bus, ainsi que de diverses interfaces d’entrée/sortie. Cependant, les routeurs sont conçus pour assurer des fonctions très spécifiques que n’effectuent pas en général les ordinateurs de bureau. Par exemple, des routeurs peuvent se connecter, assurer la communication entre deux réseaux et déterminer le meilleur chemin pour les données à travers les réseaux connectés.<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></div><div class="MsoNormal" style="font-size: 12px; margin: 0px; padding: 0px; text-align: justify; text-indent: 35.4pt;"><span style="background-color: white; font-size: 12pt; margin: 0px; padding: 0px;"><span style="font-family: Trebuchet MS, sans-serif;"><br style="margin: 0px; padding: 0px;" /></span></span></div><div class="MsoNormal" style="font-size: 12px; margin: 0px; padding: 0px; text-align: justify;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><span style="font-size: 12pt; margin: 0px; padding: 0px;">À l’instar des ordinateurs qui ont besoin d’un système d’exploitation pour exécuter les applications, les routeurs doivent être équipés d’une plate-forme logicielle IOS (<b style="margin: 0px; padding: 0px;">Internetworking Operating Software</b>) pour exécuter les fichiers de configuration. Ces fichiers contiennent les instructions et les paramètres qui contrôlent le trafic entrant et sortant des routeurs. Plus précisément, en utilisant des protocoles de routage, les routeurs décident du meilleur chemin pour les paquets. Le fichier de configuration spécifie toutes les informations pour l’installation et l’utilisation correctes des protocoles de routage et routés- sélectionnés ou activés sur le routeur.</span><span style="margin: 0px; padding: 0px; text-indent: -18pt;">      <br /></span></span></span></div><h1 style="margin: 0px 0px 0px 36pt; padding: 0px; text-align: center; text-indent: -18pt;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><span style="font-size: 18pt; margin: 0px; padding: 0px;">   <span style="color: #6fa8dc;">1.<span style="font-size: 7pt; font-weight: normal; margin: 0px; padding: 0px;"> </span></span></span><span style="font-size: 18pt; margin: 0px; padding: 0px; text-indent: -18pt;"><span style="color: #6fa8dc;">Les principaux composants internes du routeur</span></span></span></span></h1><div style="font-size: 12px; margin: 0px; padding: 0px;"><div class="MsoNormal" style="margin: 0px; padding: 0px; text-align: center;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><br style="margin: 0px; padding: 0px;" /></span></span></div><table border="1" cellpadding="0" cellspacing="0" class="MsoTableGrid" style="border-collapse: collapse; border: none; margin: 0px; padding: 0px; text-align: center; width: 536px;"><tbody style="margin: 0px; padding: 0px;"><tr style="margin: 0px; padding: 0px;"><td style="border: 1pt solid windowtext; margin: 0px; padding: 0cm 5.4pt; width: 125.9pt;" valign="top" width="168"><div class="MsoNormal" style="margin: 0px 0px 0px 0cm; padding: 0px; text-align: left;"><b style="margin: 0px; padding: 0px;"><span style="background-color: white; font-size: 12pt; margin: 0px; padding: 0px;"><span style="font-family: Trebuchet MS, sans-serif;">Les composants<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></b></div></td><td style="border: 1pt solid windowtext; margin: 0px; padding: 0cm 5.4pt; width: 276.4pt;" valign="top" width="369"><div class="MsoNormal" style="margin: 0px 0px 0px 15.85pt; padding: 0px; text-align: justify;"><b style="margin: 0px; padding: 0px;"><span style="background-color: white; font-size: 12pt; margin: 0px; padding: 0px;"><span style="font-family: Trebuchet MS, sans-serif;">Les fonctions<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></b></div></td></tr><tr style="margin: 0px; padding: 0px;"><td style="border: 1pt solid windowtext; margin: 0px; padding: 0cm 5.4pt; width: 125.9pt;" valign="top" width="168"><div class="MsoNormal" style="margin: 0px 0px 0px 0cm; padding: 0px; text-align: left;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><br style="margin: 0px; padding: 0px;" /></span></span></div><div class="MsoNormal" style="margin: 0px 0px 0px 0cm; padding: 0px; text-align: left;"><b style="margin: 0px; padding: 0px;"><span style="background-color: white; font-size: 10pt; margin: 0px; padding: 0px;"><span style="font-family: Trebuchet MS, sans-serif;">Le processeur<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></b></div><div class="MsoNormal" style="margin: 0px 0px 0px 0cm; padding: 0px; text-align: left;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><br style="margin: 0px; padding: 0px;" /></span></span></div></td><td style="border-bottom-color: windowtext; border-bottom-width: 1pt; border-right-color: windowtext; border-right-width: 1pt; border-style: none solid solid none; margin: 0px; padding: 0cm 5.4pt; width: 276.4pt;" valign="top" width="369"><div class="MsoNormal" style="margin: 0px 0px 0px 15.85pt; padding: 0px; text-align: justify;"><span style="background-color: white; font-size: 12pt; margin: 0px; padding: 0px;"><span style="font-family: Trebuchet MS, sans-serif;">Le processeur (UC) exécute les instructions du système d’exploitation IOS.

Dans d’autres routeurs, l’IOS peut être exécuté directement à partir de la mémoire flash.

Les interfaces LAN permettent au routeur de se connecter au média de réseau local. Il s’agit habituellement d’une forme d’Ethernet. Cependant, cela pourrait être d'autres technologies LAN comme Token Ring ou FDDI.</span><o:p style="font-size: 12px; margin: 0px; padding: 0px;"></o:p><br style="font-size: 12px; margin: 0px; padding: 0px;" /></span></span><br /><div class="separator" style="clear: both; font-size: 12px; margin: 0px; padding: 0px; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpBVwldEcRqOfNccYobkVSL0PCIZfYEP-2wss7RWSmIbnM-b2dxeDKqvevctVW4BdHMYMPAzvHwnq2RcBNcbk3rjz3Bz2UPZA7lk3qlJgAEH-XYzfwTcvXjPDpHoSgQa_2IR6edkzhgVCI/s1600/01-09-2012+12-03-14.jpg" imageanchor="1" style="background-color: white; color: #0000dd; margin: 0px 1em; padding: 0px; text-decoration: none;"><span style="font-family: Trebuchet MS, sans-serif;"><img border="0" height="180" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgpBVwldEcRqOfNccYobkVSL0PCIZfYEP-2wss7RWSmIbnM-b2dxeDKqvevctVW4BdHMYMPAzvHwnq2RcBNcbk3rjz3Bz2UPZA7lk3qlJgAEH-XYzfwTcvXjPDpHoSgQa_2IR6edkzhgVCI/s400/01-09-2012+12-03-14.jpg" style="border: 0px; margin: 0px; padding: 0px;" width="400" /></span></a></div><div class="separator" style="clear: both; font-size: 12px; margin: 0px; padding: 0px; text-align: center;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><br style="margin: 0px; padding: 0px;" /></span></span></div><div class="separator" style="clear: both; font-size: 12px; margin: 0px; padding: 0px;"></div><div style="font-size: 12px; margin: 0px; padding: 0px; text-align: justify; text-indent: 35.4pt;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;">Les réseaux WAN fournissent des connexions à un site distant ou à l'Internet en utilisant les services d'un provider. Il peut s’agir de connexions série ou d'autres interfaces WAN. Avec certains types d’interfaces WAN, une unité externe, telle qu’une CSU, est nécessaire au niveau de la connexion locale du fournisseur d’accès. Dans d’autres cas, le routeur peut être connecté directement au réseau du fournisseur d’accès.<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></div><div style="font-size: 12px; margin: 0px; padding: 0px; text-align: justify; text-indent: 35.4pt;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;">La fonction des ports de gestion est différente de celle des autres connexions. Les connexions LAN et WAN fournissent un réseau de liens à travers lesquels les paquets sont transmis. Le port de gestion fournit une connexion de type texte pour la configuration et le dépannage du routeur. Les interfaces de gestion communes sont les ports console et les ports auxiliaires. Ce sont des ports série asynchrones EIA-232. Ils sont connectés à un port de communications sur un ordinateur. L’ordinateur doit exécuter un programme d’émulation de terminal pour fournir une session texte avec le routeur. Cette session permet à l’administrateur du réseau de gérer le routeur (ou l'équipement).<o:p style="margin: 0px; padding: 0px;"></o:p></span></span></div><h1 style="margin: 0px 0px 0px 36pt; padding: 0px; text-align: center; text-indent: -18pt;"><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><span style="color: #6fa8dc;"><a href="http://draft.blogger.com/blogger.g?blogID=4102117462833659555" name="_Toc278370117" style="margin: 0px; padding: 0px; text-decoration: none;"></a><span style="font-size: 18pt; margin: 0px; padding: 0px;">4.<span style="font-size: 7pt; font-weight: normal; margin: 0px; padding: 0px;">   </span></span><span dir="LTR" style="margin: 0px; padding: 0px;"></span><span style="font-size: 18pt; margin: 0px; padding: 0px;">Connexions des ports de gestion<br /></span></span><span style="font-size: 18pt; margin: 0px; padding: 0px;"><o:p style="margin: 0px; padding: 0px;"></o:p></span></span></span></h1><span style="background-color: white;"><span style="font-family: Trebuchet MS, sans-serif;"><span style="font-size: 12px;">Le port console et le port auxiliaire (AUX) sont des ports de gestion.

Le port console est également utilisable avant que les services réseau soient lancés ou lorsqu'ils sont défaillants. Par conséquent, le port console peut être utilisé pour les procédures de reprise après sinistre et de récupération de mots de passe. </span></span></div></div>

les composants d'un ROUTEUR

Un routeur est un type spécial d’ordinateur. Il possède les mêmes composants de base qu’un ordinateur de bureau standard. Il est doté d’un processeur (UC), de mémoire, d’un système de bus, ainsi que de diverses interfaces d’entrée/sortie. Cependant, les routeurs sont conçus pour assurer des fonction…
