On any network, there are several causes of network congestion. Lisa Bock covers some of the bandwidth-hogging applications that include Facebook, Pandora, and YouTube and demonstrates a case study where Spotify is the culprit.
- [Instructor] On any network,…there are several causes of congestion…that prevents the data from moving freely.…One of them is low bandwidth.…This is where the amount of data…that can flow freely is reduced…as multiple hosts are contending for the same bandwidth.…Now, there are many culprits, but some of…the more common ones are voiceover IP…and streaming, video conferencing,…along with Facebook, Pandora, and YouTube.…I have this packet capture, which is Spotify,…which is a music service.…
Now, this was done in a lab situation,…but it helps to illustrate the huge use of bandwidth…that could impact network performance.…Now, when we go into this packet capture,…and it's a pretty healthy packet capture,…I want to go into statistics and then protocol hierarchy.…Now, once I'm in protocol hierarchy,…this gives us a nice ability to view…all the protocols that Wireshark has dissected.…
Now, when you're in this view,…you really can't do the same things…as you can when you're in the capture view,…but we can modify the columns, move them over,…
