Hi All

Is there a thumb rule to help us identify the minimum bandwidth needed to Internet connectivity (ATM / MPLS etc) for serving about 1000 users within my organistion?

Users would be able to browse the Internet, no downloads or chats, streaming videos etc with strict policy enforcement. Email is set at a max of 5 MB quota for attachments per user
Currently we are having 2Mbx2 leased lines load balanced and is falling way short with incoming/outgoing Mail queues going very high at peak times on our primary Mail gateway.

Pls advise!!

4mbs pipe is pretty light for 1000 users. I would recommend before going further to find out what your actual bandwidth usuage is and to know that bandwidth is the cause of the email delay. network analyzer and others will allow to monitor the traffic.

As an alternative, (we are pretty choked on bandwidth) instead of increasing oricy leased line, I can have a 2MB ADSL cheaper connectivity and re-route all except outgoing SMTP/VPN traffic through this line?

Is this doable? If Yes!! Any precautions/caveats I need to keep in mind?

Are the users cruising the net all day? I feel that you need more bandwidth, but I would want to know whats using what we have before you just throw more bandwidth at it. It could be some rogue users, or a chatty box, or some twit running a porn site, at the moment you don't know. It shouldn't be always max out is what I'm saying and you need to find out what it is before throwing money at the wrong place.
