Upload/download question

[#1]

If when uploading as well as downloading at the same time on the 38/2 fibre, would the upload speed drop?

[#2 · Accepted solution]

Potentially yes. Downloading requires some upload bandwidth to confirm/acknowledge successful receipt of data; conversely uploading requires a small amount of download bandwidth for the same purpose.

Taking a simplistic view of the situation, and assuming maximum sync rates are achieved in both directions, downloading at 38Mbps (38000kbps) will take around 750kbps upload bandwidth out of the available 1900kbps.

That's around 40%, but I emphasise this is a very simplistic analysis.

Thanks, I was wondering how much the upload would drop when using a HD webcam on Skype. So going by what you said it wouldn't be very much
