need help with streaming and bandwidth user

[arie_ronaldo1]

hello everyone, im using fortigate 1000B 4.0 and fortiAnalizer 1000C, when i query top web sites by bandwidth, alot of googlevideo.com come out, for example r3---sn-2uuxa3vh-jb3d.googlevideo.com, r1---sn-2uuxa3vh-jb36.googlevideo.com, r6---sn-2uuxa3vh-jb3z.googlevideo.com. anyone can make sense of that? please help. also when i stream youtube, fortianalyzer will categorize it as http.browser or http.video? how can i find the person who using the bandwidth over time (not volume), its like which person using 10% of pipe per period of time. thank you very much, have a nice day everyone
