Control of UDP traffic from WS-VLAM (streaming video)
The application (workflow) consists of two workflow components: a video data producer (vlc-video) and a data
consumer (vlc-player); the producer generates a video stream and transmits it using UDP protocol;
The testbed for the executing consists of computing nodes connected via two networks at the same time:
100Mbps and 1Gbps networks, by default traffic is sent over the 100 Mbps network;
A workflow vlc-video -> vlc-player is started;
Initial connection is established over 100 Mbps network;
Background network load is started on the same link with iperf tool;
Throughput drop is clearly seen as the video being played becomes highly disrupted due to a high rate of packet loss;
Another network path is requested by pressing the "Reserve path" button in the WS-VLAM GUI;
After the new network path is reserved a significant perfomance gain is visible on the video screen - the image is consistent;
The reserved path is released from the WS-VLAM GUI and the image becomes disrupted again.
