Description

Develop a integration test for route inheritance flags.

Topology

B---A---C
    |
    D

Edges represent logical links (UDP tunnels).

Steps

  1. start NFD on A,B,C,D
  2. set multicast strategy for root namespace on A
  3. run traffic generator server on B,C,D each with these prefixes
    • ndn:/A/P
    • ndn:/A/B/C/Q
    • ndn:/D/R
    • ndn:/S
  4. add routes on A
    • ndn:/ , nexthop=hostB, CHILD_INHERIT=yes, CAPTURE=no
    • ndn:/ , nexthop=hostC, CHILD_INHERIT=no, CAPTURE=no
    • ndn:/A , nexthop=hostB, CHILD_INHERIT=yes, CAPTURE=no
    • ndn:/A/B/C , nexthop=hostD, CHILD_INHERIT=yes, CAPTURE=no
    • ndn:/D , nexthop=hostC, CHILD_INHERIT=yes, CAPTURE=yes
    • ndn:/D , nexthop=hostD, CHILD_INHERIT=yes, CAPTURE=no
  5. run traffic generator client on A to send 20 Interests to each of:
    • ndn:/A/P
    • ndn:/A/B/C/Q
    • ndn:/D/R
    • ndn:/S
  6. stop traffic generator server on B,C,D
  7. in traffic generator server reports, verify the number of served Interests of each traffic pattern, fail the test case if any condition is violated
    • traffic generator server on B
      • ndn:/A/P , >=18
      • ndn:/A/B/C/Q , >=18
      • ndn:/D/R , =0
      • ndn:/S , >=18
    • traffic generator server on C
      • ndn:/A/P , =0
      • ndn:/A/B/C/Q , =0
      • ndn:/D/R , >=18
      • ndn:/S , >=18
    • traffic generator server on D
      • ndn:/A/P , =0
      • ndn:/A/B/C/Q , >=18
      • ndn:/D/R , >=18
      • ndn:/S , =0

Is there a way to set ndn-traffic to send a fixed number of interests per name (without running ndn-traffic separately for each name)? The test fails occasionally when the number of interests sent for one of the names is less than 18. (See attached files)

No. In step 4, you may run four traffic generator client instances in parallel.

The test fails occasionally when the number of interests sent for one of the names is less than 18.

If traffic generator client is configured to send 80 Interests, and there are four traffic patterns each with 25% share, it's supposed to send exactly 20 Interests per traffic pattern.

Otherwise, this should be a bug of traffic generator.

Step 7 specifies "at least 18" to accommodate packet loss.

Then I believe it is a bug. See attached client config file (and previously uploaded client.log).

No. In step 4, you may run four traffic generator client instances in parallel.

I uploaded a draft patchset that uses 4 instances of traffic generator to avoid the issue. It can be easily changed later.
