multicast / IGMP

Moderator mote: In an effort to widen the possible audience for this question, I have had this post translated from French to English using http://http://babelfish.altavista.com/tr as follows:

Hello, We want to deploy an application of videoconference on our local area network, Is it necessary to activate IGMP (protocol niv 3) to send video flows in multicast on LAN? If this is not necessary how one defines the multicast in level 2? Can activating IGMP on the SWITCH degrade the performance of the network in term of band-width? THANK YOU.

--original post--

Bonjour,

Nous voulons déployer une application de visioconférence sur notre réseau local,

Est t’il nécessaire d’activer l’IGMP (protocole niv 3) pour envoyer des flux vidéo en MULTICAST sur LAN ?

Si ce n’est pas nécessaire comment on définit le MULTICAST au niveau 2 ?

L’activation d’IGMP sur les SWITCH peut-elle dégrader les performances du réseau en terme de bande passante ?

MERCI.
