CA 2367397

A Multicast-Enabled Address Resolution Protocol (ME-ARP) is disclosed. This ME- ARP allows the building of independent IP based Virtual Private LAN segments (VPLS) over a multicast enabled IP backbone using stateless tunnels and optimal VPLS traffic forwarding. Each VPLS has an associated IP subnet which is completely independent from other VPLS or the underlying IP backbone itself. Each Customer Premises Equipment (CPE) device needs only to be configured with a VPLS identifier and its serving IP subnet per VPLS designated interface.

Cette invention concerne un protocole de résolution d'adresse activé en multi-diffusion (ME-ARP). Ce ME-ARP permet de construire des segments indépendants de réseau local privé virtuel à base de PI sur un réseau PI activé en multi-diffusion (VPLS), ceci à l'aide de tunnels sans état et d'un routage optimal du trafic VPLS. Chaque VPLS possède un sous-réseau PI associé qui est complètement indépendant des autres VPLS ou du réseau PI sous-jacent lui-même. Ainsi, il est uniquement nécessaire de configurer un dispositif des équipements des locaux d'un client (CPE) à l'aide d'un identificateur de VPLS et de son sous-réseau PI asservi par interface de VPLS désignée.
