Figure 4-29: Traffic throughput and fairness in scenario A<br />
In scenario B ( Figure 4-30), we have two FTP sources. The results show that the video stream<br />
is transmitted entirely and that the two FTP sources fairly share the remaining bandwidth. This<br />
gives a portion of 1.66 Mbit/s per flow since we have three streams. In this period, when the two<br />
FTP streams are active (30s-90s), the video stream consumes less than 1.66 Mbit/s, the remaining<br />
bandwidth is fairly shared with the two FTP sources.<br />
