[Spud] 答复: Numbers...

Hi,

I'm also confused about the following description:
"Today UDP is often blocked (“99% of UDP is garbage”) but volume of (good) UDP traffic grows, e.g. RTCWEB uses UDP for data and media"

What kind of UDP is called garbage? Why UDP is often blocked?
Could somebody please explain?

Thanks,
Jianjie
