[INTERNET] TCP session timeout?

Does Cogeco kill idle TCP connections if no activity occurs over a given time period?

I ask this because lately I have had numerous disconnects from home to our Remote Desktop server at work.

Long lasting TCP connections are known to get dropped occasionally due to a multitude of different factors, however, unless both ends send and accept keepalive packets then connections with no data passing through them will simply expire naturally.

If you're using a NAT router that's a separate state table that will expire connections, and in the case of cheap devices.. they can have trouble keeping state.

I currently have one state that's been alive for 360 hours, which is usually idle.

Thanks for the insight!

I found some articles on how Remote Desktop Services can be tweaked to send more frequent keepalive packets with a simply registry hack. Since implementing this, the problem appears to have resolved.
