The Summit has policy-based Quality of Service (QoS) features that enable you to 
specify service levels for different traffic groups. By default, all traffic is assigned with 
the “normal” QoS policy profile. If needed, you can create other QoS policies and apply 
them to different traffic types so that they have different guaranteed minimum 
bandwidth, maximum bandwidth, and priority.

The Summit can use IP multicasting to allow a single IP host to transmit a packet to a 
group of IP hosts. The Summit supports statically configured IP multicast routes, and 
multicast routes that are learned by way of the Distance Vector Multicast Routing 
Protocol (DVMRP).
