NEV Elastic Private Line (EPL) gives service providers the ability to deliver VPN services, with
end-to-end encryption, over existing access lines.
Traditional secure networking technologies (VPNs, MPLS, IPsec, SD-WAN, etc.)
operate at layer 3, or the network layer. As businesses demand more
agility and as applications share more data across clouds, networks, and applications,however, a
layer-3 approach becomes less than optimal and creates performance bottlenecks.
In contrast, NEV supports layer 2 VPNs, which has a number of advantages, including:
Increased performance due to a data-first
Ability to provide SLAs
Easier management (customers can change routing
policies without carrier intervention)
Simple, centralized troubleshooting
NEV gives service providers and enterprises the ability to deliver Layer 2 (L2)
VPN-as-a-Service over existing access lines, complete with physical isolation of resources and
the ability to offer different tiers of service over the same line.
Subscribers may sign up for the service on demand, with no operator
intervention. NEV-enabled VPN services provide end-to-end encryption and support for MAC-based
authentication to prevent spoofing attacks.
