The following test set was proposed:

• topology:
  1 producer connected to REMAP, 2 consumers connected elsewhere on the testbed (among UCLA,CSU,WU,REMAP hubs)

• general description:
  we’d like to explore how multiple consumers affect each other when fetching from the same producer. for that, one consumer will start fetching from producer, after some time (30sec) another consumer will start fetching from the same producer and we’ll see how this affects audio for both (does it affect at all). we will do several rounds of this test with one consumer connecting to different hubs on the testbed. before multi-consumer test, we’ll check that audio works decently for both consumers in 1-to-1 scenario.

• detailed steps:

  • producer P publishes audio stream; connected to REMAP.
  • audio is checked for each consumer separately:
    • 1/ consumer C1 connects to WU and fetches audio for 30-60sec from P. confirm that audio works decently. consumer C1 stops fetching. report to chat.
    • 2/ consumer C2 connects to hub and fetches audio for 30-60sec from P. confirm that audio works decently. consumer C2 stops fetching. report to chat.
  • audio is checked for both consumers:
    • 3/ consumer C1 connects to hub and fetches audio from P. after 30sec, consumer connects to hub and starts fetching audio from P. observe audio quality for both consumers for 60-90sec. report to chat

• tests set:

I. P on REMAP, C1 on WU, C2 on WU¶

1. C1 <-- P for 30sec (C1 fetches form P for 30 sec and stops)
2. C2 <-- P for 30sec (C2 fetches from P for 30 sec and stops)
3. C1 <-- P for 30sec + C2 <— P for 60-90sec (C1 fetches from P for 30 sec, then C2 starts fetching form P for another 60-90sec, then both stop)

II. P on REMAP, C1 on WU, C2 on CSU¶

1. C1 <-- P for 30sec (C1 fetches form P for 30 sec and stops)
2. C2 <-- P for 30sec (C2 fetches from P for 30 sec and stops)
3. C1 <-- P for 30sec + C2 <— P for 60-90sec (C1 fetches from P for 30 sec, then C2 starts fetching form P for another 60-90sec, then both stop)

III. P on REMAP, C1 on WU, C2 on UCLA¶

1. C1 <-- P for 30sec (C1 fetches form P for 30 sec)
2. C2 <-- P for 30sec (C2 fetches from P for 30 sec)
3. C1 <-- P for 30sec + C2 <— P for 60-90sec (C1 fetches from P for 30 sec, then C2 starts fetching form P for another 60-90sec, then both stop)

IV. P on REMAP, C1 on WU, C2 on REMAP¶

1. C1 <-- P for 30sec (C1 fetches form P for 30 sec)
2. C2 <-- P for 30sec (C2 fetches from P for 30 sec)
3. C1 <-- P for 30sec + C2 <— P for 60-90sec (C1 fetches from P for 30 sec, then C2 starts fetching form P for another 60-90sec, then both stop)
