When a user connects his home computer via cable modem to his mail server at work; who’s bandwidth is used? Isn’t his computer doing most of the pushing and pulling and his ISP’s bandwidth being used or is it the servers?
Thanks!
Subject: It is pretty much equal.
A packet (or many packets) are being sent from the user to the server. They take the same bandwidth. The server may be much busier, thus not accepting packets as fast as the user can send them, so the user may not be using his full bandwidth. With streaming replication in R6 there is less overhead in that Packets do not have to be acknowledged in order for the next one to be sent. Also remember that in a typical Cable Modem connection the users Upload bandwidth is much less than his Download bandwidth.
Subject: It is pretty much equal. Would you recommend?
Would you say that its better for the user to be in Home mode with his location document or Office? We’re concerned about poor server performance for remote users. I believe the major issue is bandwidth and not server load.
Thanks,

The location document itself will not effect performace. That document is just instructions (suchas the type of connection, mail file location, etc.).
What matters is where the smallest pipe is. In my painful dialup situation at home (no DSL or cable available), pushing or pulling, I am still watching the grass grow while I wait.

We have an existing policy where remote users replicate their mail files over and work locally in certain offices where they have no local server. We have many users who work from home and would like to accomodate them as effectively as possible.
Now with the lower overhead of ND6 and cable modems being so prominent is it still necessary to replicate over and work locally? Would the upload tax the server anymore than a user working onsite at the office?
Thanks,

Replication and working locally cannot hurt them, especially if the bandwidth on their cable modem is being chewed up by others.
As I said, where my house is, I cannot get cable or DSL (God bless Bellsouth), Satellite DSL makes no sense, and since IBM no longer pays for my ISDN line, I am not going to pay for one myself.

We have found that users that are in remote offices or at home work best with using the travel/home location with the replication schedule kicked up to every 10 minutes or so. We probably have 30 or so users set up like this and don’t notice much of a drag on our server.
