Test 5: Cobalt Queue Disc Enhanced Blue Test Item This test checks that the Blue Enhancement is working correctly.
This test checks that Pdrop should increase as expected with a certain number of dropped packets which is fixed by assigning a stream to the uniform random variable. This test case is divided into 2 sub test cases 1) With Blue Enhancement enabled, the test checks that Pdrop should increase as expected with a certain number of dropped packets which is fixed by assigning a stream to the uniform random variable. 2) Without Blue Enhancement, Pdrop should remain zero and there should not be any dropped packets as ECN is enabled.
