VoIP's in titanium, VPN is in gold, sorry if that wasn't clear. The positioning of VPN above email and FTP and browsing is something I can see being debated for a while. Traditionally I'd say email would be of higher importance that VPN, but things like the recent snow is showing that businesses are increasingly using VPN and other remote access, there's some graphs from Bob somewhere that show the increased amount of remote access traffic from when it snowed.
I've started a new thread with this quote, because the discussion that leads on from this is slightly off-topic to the original thread it comes from (Usenet priorities), although the two are related.
I though it would be worth gathering other people's thoughts on the traffic priorities they see as important on business accounts. I would definitely put VPN above most other protocols, but after VoIP & other real-time applications. Email I actually put quite low, so long as it never stops. I don't know about you, but I never sit & watch my email arriving - it just turns up in my Inbox & bleeps at me. It was different in the dial-up days, when I would have given it a higher priority. If I need to chat to someone back & forth, I use an IM client or pick up the phone.
The problem with VPN from an ISP's point of view is that it's just a wrapper. The whole spectrum of internet traffic can be going on inside it. I use it to become a WinTS client on a server & do everything from copying files locally (akin to an HTTP download, say) to running applications on the remote server. These aren't start & let run applications, they require constant user input, so speed is important. Fortunately, for this purpose, WinTS puts relatively little strain on the network link, as unlike standard Windows networking, it's a proper client-server application.
Remote desktop protocols of all types are all very speed critical. I use VNC a lot, or variants of it (TightVNC & UltraVNC mostly)& there are plenty of similar systems. Our current business model is built around these communications protocols being fast & available.
So my priorities are:
Voice over IP
Instant Messaging (text only

)
VNC & similar
VPN
web browse & download
email
probably something else I have forgotten
Usenet
What about the rest of you?
