Hey Guys, I sell wireless telecom by day and developed a nascent understanding of data networking solutions (landline). Specifically, old generation network architecture like 'private lines' and 'atm' were sold as truly private (unbreakable) data transmission networks. Current generation network protocol - like IP VPN or MPLS - are sold as 'private' networks, but, in my understanding, push data over the internet - albeit encrypted. As a wireless sales guy, my technical understanding is limited to the reductionist talking-points and buzz words pushed by instructors. So im inable to differentiate between sales propaganda and technical fact. My question centers around Private Lines versus "Private" IP VPN (MPLS)? Are either truly private? If so, how? Also, how can MPLS be private if data is routed over the internet (encrypted)? Ive been told MPLS is private because data is routed over our telcos "private internet backbone". Is this just BS or what? The purpose here is to explore a truly private data networking solution between my trading computer and broker.
