I-FLY WIRELESS LAN ROUTER ADSL

CHAPITRE 4: Assistant de configuration

4.1 Introduction

Le Wizard Setup permet de configurer rapidement l’ I-Fly Wireless Lan Router ADSL grâce à une procédure pas à pas. Avant de commencer la configuration, il faut connaître toutes les données relatives au compte ADSL fourni par le FAI.

4.2 Encapsulation

Il faut utiliser le protocole d’encapsulation demandé par le FAI. Le Router ADSL supporte les protocoles suivants.

4.2.1 RFC 1577 (ENET ENCAP)

Le MAC Encapsulated Routine Link Protocol (ENET ENCAP) est implémenté seulement avec le protocole de réseau IP. Les paquets IP voyagent entre l'interface Ethernet et le WAN puis ils sont formatés pour pouvoir être utilisés dans une implémentation bridge. Ils sont donc transformés d’Ethernet en des ATM bridge. La modalité ENET ENCAP demande de spécifier l’adresse IP de la passerelle dans le champ “Ethernet Encapsulation Gateway” présent dans la deuxième fenêtre du Setup.

4.2.2 PPP over Ethernet

Le protocole PPPoE fournit des services de contrôle et de transport comme une connection Dial-Up avec protocole PPP.

Le router encapsule la session PPP basée sur RFC 2516 et la retourne à un PVC (Permanent Virtual Circuit) ATM connecté à un concentrateur d’accès ADSL.

4.2.3 PPPoA

Le protocole PPPoA signifie Point to Point Protocol over ATM Adaption Layer 5(AAL5), il fournit des services de contrôle et de transport comme une connection Dial-Up avec protocole PPP.

Le router encapsule la session PPP basée sur RFC 1483 et la retourne à travers un PVC ATM au DSLAM du FAI.

4.2.4 RFC 1483

L’ RFC 1483 décrit deux méthodes d’encapsulation multi protocole sur ATM Adaption Layer 5(AAL5). La première méthode permet le multiplexage de plusieurs protocoles sur un seul PVC ATM, la deuxième que chaque protocole est transporté sur un PVC ATM différent.
