Multicast Switching
Specific multicast traffic can be assigned to its own VLAN to ensure that it
does not interfere with normal network traffic and to guarantee real-time
delivery by setting the required priority level for the designated VLAN.
The switch uses IGMP Snooping and IGMP to manage multicast group
registration.
Traffic Priority
This switch provides Class of Service (CoS) by prioritizing each packet
based on the required level of service, using four distinct queues with
Weighted Round Robin queuing for each port. It uses IEEE 802.1p and
802.1Q tags to prioritize incoming traffic based on input from the
end-station application. Also, the switch provides Layer 3/4 priority
mapping of IP Precedence/DSCP values or IP TCP/UDP port numbers
to the IEEE 802.1p priority tag of each frame. These functions can be
used to provide independent priorities for d ifferent types of traffic, such as
delay-sensitive data and best-effort data.
