Experimental Setup
Because it is impossible to measure data traffic between two VM ware's on the same machine, the following setup is used.
Legenda:
- Black: Traffic between the Asterisk-boxes in one direction.
- Blue: Traffic between the Asterisk-boxes in the other direction.
- Red: Traffic to and from SIP phone 301
- Green: Traffic to and from SIP phone 201.
- Pink:
Used filters in I/O-graph:
Filter-Black: ip.src == 192.168.1.101 && ip.dst == 192.168.1.106 Filter-Red : ip.src == 192.168.1.3 && ip.dst == 192.168.1.106 Filter-Green: ip.src == 192.168.1.189 && ip.dst == 192.168.1.101 Filter-Blue : ip.src == 192.168.1.106 && ip.dst == 192.168.1.101 Filter-Pink : ip.src == 192.168.1.100 && ip.dst == 192.168.1.101
From the graph shown above there can be concluded that the IAX2 traffic (black and blue line) uses less bandwidth than the SIP-traffic (red and green line). We also filtered for traffic between all three SIP-telephones and no traffic was detected.
