Looking to understand the options available in WAN machine to machine communication. Cellular providers provide MPLS based VPN. IPSec VPN is another option available over the public internet.

What are the pros and cons of using the above two. Any other frameworks/protocols that can be used in wireless or wired wide area networks. Looking to address end-to-end connectivity options here.

Thanks in advance!!

Your question is a little to broad. Maybe you could rewrite your post to ask a precise question about a certain problem you are facing. Please read the FAQ- security.stackexchange.com/faq – Dinu S Jan 13 at 18:28
I believe MPLS and IPSec VPN are network frameworks. MPLS is best recommended as a core network framework whereas IPSec VPN is best used outside of the service provider's core. Another option at the application layer is SSL VPN. I am looking to investigate any other frameworks/connectivity options available in machine-to-machine communication. – Sriram Jan 14 at 18:06
Sririam, as Dinu said, please read the faq and update your question to ask about a problem you are facing, then we can re-open it. – Rory Alsop♦ Jan 29 at 13:27

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

I found a nice spreadsheet titled, "Is IPSec or MPLS VPN right for you?" It seems to be targeted at more of a enterprise customer but if nothing else, it should help to refine your question. http://www.netforce.com.au/nf_prod/nfwebsite.nsf/webpages/Newsletter-January2008/MPLSvsIPSecVPN?OpenDocument
