Traditional virtual private network (VPN) services from providers are usually based on rigid functionality that can be deployed across the widest customer base. Unfortunately, this leaves little room for per-enterprise customization, forcing businesses to use complex branch networking to get the different network capabilities they need for each location.
A new white paper from Nuage Networks, “Flexible Network Services to Drive Your Enterprise at Cloud Speed”,” looks at how the company uses software-defined networking (SDN) in the wide area so organizations can easily customize connectivity and seamlessly link locations regardless of size or geography.
Nuage Virtualized Network Services (VNS) separates wide-area network service from the underlying connectivity, reducing the need for customized branch networking. Based on Nuage’s network virtualization solution for data centers, Nuage Networks VNS gives organizations the power to choose the best-fit network provider for each of their sites.
Unlike traditional VPN services — which are tightly connected to dedicated network infrastructure from a service provider — Nuage VNS is based on an overlay model that uses any IP network to provide underlay connectivity between sites. The white paper explains how this provides maximum flexibility for different locations and supports multiple access/last-mile technologies including copper, fiber, and mobile broadband. Other benefits include:
- Enterprises can completely control moves, adds, and changes, which are centrally driven on a per-site or whole-of-network basis;
- Customizable network functions are included in the solution, reducing the need for dedicated elements such as firewalls and security;
- Service manageability improves, and the complexity around auditing and compliance for industry bodies and regulators decreases.
Nuage Networks VNS requires only an IP connectivity service to operate, so organizations have the flexibility to mix and match available networks from multiple providers, and use any available access technologies.
Nuage Networks envisions VNS will replace a number of physical network appliances currently required at branch locations, increasing network stability while simplifying networks overall. Read the white paper to learn more about how VNS can drive a significant reduction in network infrastructure costs and increase the choice of providers and service offerings.
