T1 Dedicated vs. Cable/DSL over VPN

Medium Priority
Last Modified: 2013-11-10
Trying to figure out which direction to go with connecting off campus locations. We are able to afford T1 Dedicated links at 1.5 MB at 243/month. Colleagues are suggesting using DSL 8 MB or Mediacob Cable at 8 MB with VPN. Of course our Internet pipe is congested during the day which is our main vpn connection. What would be the better solution for 12 People connecting back to campus.
Watch Question

Leased Lines are always more reliable. I guess it depends on how much traffic you are going to be sending. If you have data intensive apps running on the WAN, you should go with DSL/Cable. If link reliability is a requirement, go with T1.

Most DSL and Cable now are offering 5+ MB download and vary on the upload from 512kbps to 1mbps.  If the VPN is going to be mostly download from the school to the end user then go with DSL/Cable.. if you need the same upload then make sure what those upload speeds will be.  Also DSL/CABLE run about 70 a month so you could actuall get 1 DSL and 1 CABLE split the users and still save money and have some type of redundacy.


From previous attempts the users easily saturate 1.5 MB and that is both ways they use blackbaud applications which is sql based. Reliability is an issue as we have IP phones.. At the most we probably would need around 10 MB full duplex..Thoughts?
Then your next step is a partial T3 which is ALOT of money... you might see if the ISP has some better bandwidth.. maybe fiber..
Also on the VOIP add a voice gateway on their end for analog calls so it is not using the bandwidth.

If you are in the US, ask your cable provider about MetroEthernet.

What's your budget?

You can connect all remote sites back to the main campus by using MPLS T1s.  It supports  QoS, so once properly configured, your ip phones will have priority.   These sites will not be using your Internet port for inbound connections, so the fact that the Internet port gets congested won't have the kind of impact you described above.  MPLS should also be cheaper than private lines.


preferrably 200 - 400 dollars per month on budget. In terms of MetroEthernet .. We are based in a rural area and Metro does not sound like an option.. What is MetroEthernet??


The Metro and MPLS are not available to our organization we live in the middle of a corn field but reliability is a factor with through put being another issue. We do have a cable connection we use to test out VPN and firewall issues and were thinking about using these 2 in pair where we send port 80 to the cable modem and anything destined for campus through the T1.. Thanks



We have gone with combing a unused cable internet conection with our T1 connection as a test at this point and time. The technologies of MetroEthernet and MPLS are not available in our area unfortunately. Thanks to all for your suggestions...
