I need some advice please. I am in the process of gathering quotes for upgrading (replacing) our network. We currently have three locations in a hub and spoke configuration. Sites A, B and C where A is the hub, B and C are the spokes (remotes). We currently use a fiber solutions from Verizon which is a transparent LAN services circuit with A having 100/100mbps and remotes having 10/10mbps. This hasn’t been a bad setup but it does not meet or current needs of 100mbps at the remote. I can upgrade the remotes to 100mbps and the hub to 1gig but the cost is prohibitive. Also in the scenario is a 40/40 fiber internet connection from another vender which serves all three locations. I do not (but would like to) offer wifi at the remotes. I don’t now because I don't want to slow the WAN connection down any farther then they already are. The internet connection is also used to connect a couple of web sites we host internally and to connect 6 small site-to-site VPNs and SSL VPN clients through a Sonicwall NSA appliance.
I am looking into going the MPLS route with site A on 200/200 and B and C on 100/100 with all three sites using a firewall internet gateway (in the cloud) of 100/100 for internet access.
I am also exploring getting higher bandwidth Internet connection at each location again 200/200 at A and 100/100 at B and C and using NSA’s to connect site-to-site VPNs.
Also in the mix is an older PBX/IP hybrid phone system (PRI at each location) which has an ACD group at site A uses the network for 4 digit dialing, auto attendant 70+ digital extensions and 4 IP phones.
I am having trouble deciding what the best options are, I am using a couple of consultants to explore options and pricing for me. The goal is to have the 100/100 at the remotes for our business traffic which is general file sharing, email hosted at site A and large image files (200+mb per file, multiple files per day). We hope to be replacing the phone system over the next year or two and I want to put in place a network that can handle the large image traffic and also be a solid foundation for a more robust phone system in the future weather that is cloud based or hosted, digital PBX or IP based (prefer going to IP phone route for email client integration).
Using the information supplied can I please get advice on what you think are the best options to build the network? Cost is a consideration.
Thank You for you time and input.
