We have 2 locations in US and 2 offices in 2 other countries. We are currently on an MPLS network between our 2 US locations, which handles data/VoIP. I'm wondering if we should stay with MPLS or go with basic internet access(BIA) and build VPN's between to handle our data/VoIP traffic.

Hub office has the most phones 55 and the remote range from 3 to 15 phones per locations, so not a lot of bandwidth eaten up by voice. Data between the offices will not be overwhelming, just some source code transferred in the evening from the other country locations.

Trying to way out the pros/cons of each, basically.

The biggest difference is that the MPLS based solution is a private VPN isolated from the Internet. Your carrier has optimum control of the traffic between your sites and all traffic is kept on their network. This means they can provide predictable performance and security via traffic isolation for your MPLS based VPN. The downside is that it will cost you more.

The Internet solution will not provide you end to end predictable performance.  This is because you are at the mercy of "best effort" forwarding on the Internet, no guarantees. With an Internet solution things could work great one day then the next the could be bad. In my opinion this cold be a very painful scenario.

In the end it will depend on your tolerance of sub optimal performance of the Internet.

harbor235: "In the end it will depend on your tolerance of sub optimal performance of the Internet." when you state this, in reference to a BIA?

Thank you

Yes, because the internet is best effort, there is no QOS/COS or predictable ltency, packet loss, etc .....

Highfive Gives IT Their Time Back

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!
