In pure MPLS IP VPN environments without Internet access, where the network is used to connect different sites, no information is open to third parties or the Internet. Therefore, hackers are unable to access any data nor can they obtain any IP address information.
MPLS IP VPN Encryption
MPLS IP VPN is a scalable model that allows customers to securely connect sites to each other, but it doesn’t typically include added encryption. The MPLS VPN architecture is fairly hack-proof (unless there is a critical configuration flaw); MPLS VPN encryption is performed using IPSec, which essentially is a suite of protocols designed to provide a secure IP based pathway between two or more endpoints.
What Are MPLS Networks?
MPLS stands for Multi-Protocol Label Switching, which are networks that enable users to create end-to-end circuits across any type of transport medium via WAN technology. Until recently, customers wanting to connect offices in multiple locations were limited by the few WAN options offered by service providers (e.g. Frame Relay or T1/E1 links). In addition to limited options, WAN technologies are usually expensive and complex to manage.
How Do MPLS Networks Work?
MPLS works by tagging the traffic entering the network, identifying the Label Switched Path (LSP) in order to properly route the packet to the right destination. Once identified, it is then forwarded to the next-hop router. A different label is used for every hop, with the label chosen by the router performing the forwarding operation.
One of the advantages of MPLS networks is the establishment of built-in service quality. MPLS service providers typically offer their customers a service level guarantee.
