Hi,

I want to learn the pros and cons of using VPN, MPLS and VSAT technologies. We are planning to connect offices across international locations and want to do a cost benefit analysis considering security aspects as well.

Request you to among other things rate the above mentioned technologies on:

a) security (e.g. VPN :2/10 , MPLS: XX, VSAT: XX)
b) performance
c) cost (e.g. MPLS = 10 times VSAT etc).

Also, detailed pros and cons of each would be of great help.

Thanks,
Himanshu

Well we have several MPLS and VPN setups (no VSAT) so I can tell you what we have experienced.  The best bang for the buck has been the VPN.  We can get very high speed inet at both locations and create VPN tunnels with maximum security settings.  Our MPLS network is much more secure (everything is in its own cloud) but the cost is MUCH higher and the speeds a great deal slower.  For our situation, I had to do a risk assessment and let some people higher up than myself decide what they were more comfortable with.  I for one would recommend the VPN solution.

Not knowing what countries you would be in, I would recommend VPN. You can obtain dedicated lines to any number of ISPs at a good cost and with the encryption options available, it would be very secure. The only downside is that you can't provide QoS for VPNs over the Internet. It's only best effort. If that's important and price isn't then go for MPLS. Every company I work with has moved away from VSATs. They are slow and expensive and not worth the headaches.

connectivity is required between offices in India and offices in gulf countries (e.g. Oman, Kuwait etc.).

Anything on the Internet has the possibility of being decrypted. Best practices of picking strong protocols and keys should mitigate that. The biggest concern between MPLS and VPN is QoS and cost. I've run networks in Central and South America with VPN and have had no problems even with VoIP. If you have the budget for MPLS, go with that. If its too expensive or unavailable, then go with VPN.
