Our company has a satellite office that we use to connect to a Windows Terminal Server that belongs on our Domain. We have less than 50 users on this particular network. However, we typically only have 5 users logged on to the terminal server at any one time. As of right now, we are connected via VPN using two Sonicwall NSA 3500 firewalls on a 5 Mbps T1 Bond. The use of MPLS was suggested, but I have heard it is extremely expensive, and I am curious if the investment would be justifiable. Furthermore, I am skeptical that MPLS would speed up RDP and Active Directory traffic. We do not transfer large files between the network, nor do we have any unique services that would be flooding the VPN pipe.
We are considering to setup SQL replication in order to have a backup server at the satellite office. Would/should MPLS drastically affect the bandwidth between the two locations, or is MPLS more or less used on massive networks that have routers being pushed to maximum processing?
Again, our network has less than 50 users, and I hardly find this justifiable.
Many thanks in advance!
