First set of experiments was set up on testbed 1972. There was cross traffic between H5 and H2 (ping with 1000 bytes packets with 0.2s interval between them) on both VLAN21 and VLAN22. Packets were captured on H4, H3 and H2 on eth2 links (ingress for echo requests). In parallel, d-cart system was used between H4 and H2 in order to verify the capturing results. Packets have been captured and the links monitored with D-cart for approx. one minute in both experiments.
The first set of results is here (captures are in 4 different formats, sorted by the VLAN):
Capture from H4
Capture from H3
Capture from H2
D-cart results for this setup are here H4-H2
The format is the following:
code timestamp seq_num delay
code := 1 (loss or unordered packets), 2 (#hop change - not used in gts), 4 (significant delay change), 8 (heartbeat - every 100 packets)
if the code is even then you have a H(istory) with the last packet received and its own info...
The sending calibration is: 1 dcart ping (smallest possible packets but "full" of extra info) each 100ms
In the second setup, netem tool was used on a link H3-H2 with the following parameters: delay 100ms 2ms distribution normal loss 10%
The set of results of the measurements with netem switched on on H3-H2 is here:
Capture from H4
Capture from H3
Capture from H2
D-cart results for this setup are here H4-H2 (w. netem)
