9 QOS
QoS (Quality of Service) provides different levels of service for various Network
applications and requirements. It helps optimize the bandwidth distribution to provide
Network service of the best quality.
QoS
This Switch Classifi es the Ingress packets, then Maps the packets to different Priority
Queues and forwards the packets according to specifi ed Scheduling Algorithms.
Figure 9-1 QoS function
„
Traffi c Classifi cation: Identifi es packets conforming to certain characteristics.
„
Map: The user can Map the Ingress packets to different priority queues based on the
priority modes. This Switch implements three priority modes based on Port, 802.1P
and DSCP.
„
Queue Scheduling Algorithm: When the Network is congested packets compete for
resources this is solved using Queue Scheduling. The Switch supports four Priority
Schedule Modes: SP (Strict Priority), WRR (Weighted Round Robin), SP+WRR (Strict
Priority+Weighted Round Robin) and Equ (Equal).
