Central Arbitration

• Access to fabric for unicast traffic controlled using central arbitration

‒ Ensures fair access to available bandwidth on each egress port

‒ Can provide no-drop service for some traffic classes

• Arbiter ASIC on Supervisor Engine provides central arbitration via

dedicated arbitration path to every module

• Arbitration performed on per-destination, per-priority basis

‒ Ensures high priority traffic takes precedence over low priority traffic

• For multidestination traffic, no central arbitration

‒ Ingress broadcast, multicast, unknown unicast frames sent unarbitrated
