Example 4 SP-WRR
We send 4 Streams (Stream0, Stream1, Stream2 and Stream3) from GE-1 to GE-2. These Streams each
have 100Mbps. Stream0 includes VLAN Priority0, Stream1 includes VLAN Priority1, Stream2 includes
VLAN Priority2, Stream3 includes VLAN Priority3 and Stream4 includes VLAN Priority6. Stream5,
Stream6, Stream7, Stream8 and Stream9 only for learning which make sure the traffic are not flooding.
WRR support weight assignment, the range of weight value is from 1 to 255. Bye the way,
RACK-MOUNT SWITCH applies WRR scheduling and weight 1 for all the Gigabit Ethernet Port. In the
following case, we will assign Weight 1 for Priority0, Weight 2 for Priority1, Weight3 for Priority2 and
Weight4 for Priority 3. In SP-WRR mode, queue0 to queue3 belongs to WRR, queue4 to queue6
belongs to SP.
Expected Result:
In Case 1, we expect GE-2 can receive about 10Mbps of Stream0, 20Mbps of Stream1, 30Mbps of
Stream2 and 40Mbps of Stream3 if we send Stream0 to Stream3 to GE-1. In Case2, we expect GE-2
only can receive 100Mbps of Stream6, and Stream0 to Stream3 will be discarded in another case. This
case will help user to know how SP-WRR works on the RACK-MOUNT SWITCH.
Case 1:
