A Virtual Private Network ( VPN) delivers private network services over a public infrastructure.
An IP VPN is a partitioned private network constructed over a shared IP-based backbone that
utilizes technologies to ensure privacy of data. They offer enterprise-class scalability and
reachability across multiple IP-based infrastructures, along with many of the performance and
security characteristics traditionally found only in dedicated private environments.

MPLS (Multi Protocol Label Switching) technology based VPNs combines the intelligence of private
IP routing with the added performance of label switching to move packets between any location
on the network. With only one access link to the MPLS “cloud” from each of your locations, full
mesh connectivity will improve your network scalability, reliability, and internal network application performance.

MPLS also provides a greater degree of security for voice and other types of business traffic since
each VPN is a virtually separated network infrastructure over the SLT's MPLS IP Backbone.

SLT IP VPN gives you choices in your network design of sophisticated VPN technologies, access,
security and voice, with the flexibility to add on options such as remote access and hosting in
