Internet security has been up for debate for quite some time now but still users seem in denial for using the processes and systems that can mask their internet security. The redundancy of this concept is however somewhat alleviated by some thoughtful users that use either a proxy or VPN for the sake of hiding their online activity from hackers and cybercriminals.
MPLS loosely translates into a multi-protocol label switching system. It is a way to ensure reliable connections for real-time applications but it is extremely expensive to do so. It is simply a technique and many users out there confuse it with a service, it can deliver high-fi bandwidth for the wireless as well as the LAN networking but illogically it is extremely expensive and that is why common people/users use WAN as its alternative.
