Subject: Queues for multicast traffic

Hello,

Does a router require / need to have separate egress queues for
multicast and unicast traffic? That is, is it needed to take the unicast
/ multicast character of an IP packet into account when scheduling a
packet on the output port / egress interface?

RFC 2932 (IPv4 Multicast Routing MIB) defines the
'ipMRouteInterfaceRateLimit' object in the ipMRouteInterfaceTable. This
could be achieved by using a separate queue for multicast traffic.
However, the question here is whether or not this rate limiting is
effectively used in practical (deployed) networks.

Thanks for your answer.

Kind regards,

    Francis.
