difference between vpn and mpls

Thanks. We'll let you know when a new response is added.

The main difference is that IP VPN is a point to point VPN. If you have 5 sites, they all have tunnels (two actually since they are unidirectional) to each other. So five sites = (5(5-1))2 or 40 unidirectional tunnels.

MPLS VPN is a multipoint technology by design. There are no tunnels, when site 1 needs to talk to site 2, it looks up the site in the routing table, adds a tag that is for that site, and send the packet to the next router

    Both are relatively secure as well...in case that matters.

    VPN here, you probably mean IP VPN. MPLS also includes L2 VPN and L3 VPN. MPLS L2 VPN includes VPWS and VPLS which correspoinding to point to point VPN and point to multpoint VPN. There are too much stuff required to cover to make it clear. Put in simple way, VPN is a way to secure the data traffic through an encrypted tunnel. MPLS is a protocol which is kind of technology just like IP. So sometimes, you often see MPLS comes up with IP such as IP/MPLS. Hope it will not confuse you much.

    A VPN works by using the shared public infrastructure while maintaining privacy through security procedures and tunneling protocols such as the Layer Two Tunneling Protocol (L2TP). In effect, the protocols, by encrypting data at the sending end and decrypting it at the receiving end, send the data through a "tunnel" that cannot be "entered" by data that is not properly encrypted. An additional level of security involves encrypting not only the data, but also the originating and receiving network addresses. Multiprotocol Label Switching (MPLS) is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table

    That's a great question. SearchEnterpriseWAN.com has a tutorial answering that very question here: MPLS VPN fundamentals. I hope it helps!

    A VPN network creates a secure connection over a public network such as a public telecommunication infrastructure, that is, the internet being one of the most important requirements of our daily lives. The encryption for such a connection is provided by using algorithms for having security and the establishment of a reliable connection which is not possible in the case of a proxy server.
