Case 1

Topology and route:

       /a

   A ------> B

1. A expresses Interest i1 /example/testApp/randomData without Link object.
2. A waits for i1 to timeout.
3. A delays a short period of time (see below).
4. A expresses Interest i2 /example/testApp/randomData with Link object delegating /example/testApp to /a.

Expected: Interest i2 is forwarded to B.

Actual: Interest i2 is not forwarded to B if step3 delay is less than 100ms. The behavior is as expected if step3 delay is greater than 100ms.

Case 2

Topology and route:

       /example      /a

   C <---------- A ------> B

1. A expresses Interest i1 /example/testApp/randomData without Link object; InterestLifetime is set to 1000ms.
2. i1 is forwarded to C.
3. C responds Nack-NoRoute to A.
4. A waits for the Nack.
5. A delays a short period of time (see below).
6. A expresses Interest i2 /example/testApp/randomData with Link object delegating /example/testApp to /a.

Expected: Interest i2 is forwarded to B.

Actual: Interest i2 is forwarded to C if step5 delay is less than 1000ms. The behavior is as expected if step5 delay is greater than 1000ms.
