– Arbitrary mapping of DSCP to switch priority, configurable priority source selection.

– Scheduler: 8 traffic classes, arbitrary mapping of switch priorities to traffic class, deficit weighted round-robin or strict

priority.

– Notification: Two congestion notifications can be supported;

– Virtual output queue congestion notification (VCN) and Intel proprietary backward congestion notification (FCN).

– Open Flow support (consistent with OpenFlow protocol standard)

– sFlow support

User defined Packet transmission with two optional modes: 1. Simple mode

– transmit on specific port. 2. Switched

mode

– where switch determines destination port/ports, or with specific information such as whether or not egress

processing rules should be applied.

Storm Control Management

– Switch can support a variety storm controller. Each storm controller can be

programmable to define rat, condition (like unicast ICMP frames whose TTL is at most 1), frame type (can be OR’ed),

ingress & egress port ports. Actions: do nothing, drops frames to port (according to filter)

*Future SW supports.
