Bidirectional Flow
To efficiently load balance the traffic, packets are allocated between two logical counter-rotating paths.
Each counter-rotating path supports 16 Gbps in both directions, yielding a traffic total of 32 Gbps bidirectionally. The egress queues calculate path usage to help ensure that the traffic load is equally partitioned.
Whenever a frame is ready for transmission onto the path, a calculation is made to see which path has the most available bandwidth. The entire frame is then copied onto this half of the path. Traffic is serviced depending upon its class of service (CoS) or differentiated services code point (DSCP) designation. Low- latency traffic is given priority.
When a break is detected in a cable, the traffic is immediately wrapped back across the single remaining
16-Gbps path to continue forwarding.
