CONVERGENCE
P
riority queues Eight hardware queues per port
Traffic prioritization Flow-based QoS profiles
Ingress and egress
Remarking of packets based on priority:
• Auto classification of NBX telephones
•
Selectable prioritization
• Diffserv Code Point (DSCP)
• Type of Service (ToS)
• IEEE 802.1p Class of Service (CoS)
• IP precedence
• Local precedence: physical port, source/destination MAC address, VLAN
information, Ethernet type, Layer 3 protocol, source/destination IP address,
DSCP
, datagram type, IP Layer 4 protocol, IP Layer 4 ports
Bandwidth management
Flow based bandwidth management
Flows identified through Access Control Lists (ACLs)
Minimum and maximum thr
esholds:
• 64kbit/s incr
ements
• 128 traffic classes per port
• 512 flows per class
Queue handling Random Early Detect/Discard (RED)
Queuing algorithms
Strict Priority Queuing
Weighted Round Robin (WRR) provided through bandwidth management
