The Effect Of Video Streaming On A Network

by on January 30, 2008

Q: Can watching videos or listening to the radio online slows down my internet and network for the rest of the users?

A: The answer to this is yes but it depends on your network configuration as to how much it would effect other users.

The average audio feed (listening to the radio) takes about 128 kbps, which is about 1/12th the available bandwidth of a T1.

The average streaming video uses about 300 kbps, which is about 1/5th the available bandwidth of a T1 line.

If we do the math we notice that if we have a few people using an audio feed and a few people using video feeds the bandwidth of a T1 could easily be consumed, which would cause the internet to be slow for everyone in the office. Users trying to send or receive email are going to encounter dramatic slowness and many times errors and failures trying to do so because the network’s bandwidth is being used for entertainment purposes.

I hope that this gives you an idea of how video and radio can absorb an extreme amount of bandwidth from the network.
