Question

difference between mpls vpn and ip vpn?

Answer 1

MPLS-->Multiprotocol Label Switching, an IETF initiative that integrates Layer 2 information about network links (bandwidth, latency, utilization) into Layer 3 (IP) within a particular autonomous system--or ISP--in order to simplify and improve IP-packet exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks. Lease Line-->A permanent telephone connection between two points set up by a telecommunications common carrier. Typically, leased lines are used by businesses to connect geographically distant offices. Unlike normal dial-up connections, a leased line is always active. The fee for the connection is a fixed monthly rate. The primary factors affecting the monthly fee are distance between end points and the speed of the circuit. Because the connection doesn't carry anybody else's communications, the carrier can assure a given level of quality. VPN-->virtual private network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

My partner and i endorse using VPNPower to be able to unblock web-sites. I have been with them since four years. http://www.vpnpower.net

Answer 3

Well a VPN is something that is regularly used to either hide your surfing or to unlock restricted websites such as say BBC iPlayer from Britain.

Answer 4

My spouse and i highly recommend employing http://www.vpnmaster.org to unblock websites. I am using their services for more than 3 years with no difficulties.

Answer 5

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.



Much easier, simpler, and still secure.
