While enterprise data centers are rapidly adopting more flexible and automated networking with software-defined networking (SDN), the innovation usually stops short of branch offices. Instead, branch architectures still rely on expensive, proprietary network equipment and slow, complex configuration processes – making it nearly impossible for virtual private networks (VPNs) to reap the full benefits of the cloud.
Now, Nuage Networks is bridging the gap between data centers and enterprise branch offices with Virtualized Network Services (VNS), a new wide-area network service construct that has the potential to speed the deployment of new sites by a factor of ten, while reducing operational expenditures by more than 50 percent.
Specifically developed to serve enterprises adopting a cloud-based IT consumption model, VNS separates the network service from the network transport, providing the flexibility to choose branch connectivity from all available network providers. Traditional VPN services are based on set functionality that can be deployed across the widest customer base, leaving little room for per-enterprise customization and forcing complex custom-branch networking. VNS is based on an overlay model that uses any IP network to provide connectivity between sites and eliminate the network complexity.
A new solution sheet explains how the Nuage Networks Virtualized Network Services solution extends the benefits of policy-driven network automation and application-friendly abstraction to branch locations. The sheet outlines VNS’ three key functions that work together to allow advanced network functions to be deployed as part of the core service:
- Virtualized Services Directory: a programmable policy and analytics engine that provides a flexible network policy framework that enables administrators to define and enforce the business policies being applied across the network service
- Virtualized Services Controller: a powerful SDN controller that functions as the robust network control plane for the network services, maintaining a full view of the network and service topologies
- Network Services Gateway: the network-forwarding plane for the network service at the central and remote locations
Nuage Networks Virtualized Network Services is a complementary service to existing IP and Carrier Ethernet (CE) VPN services to provide maximum flexibility and the support of multiple access/last-mile technologies including copper, fiber, or mobile broadband.
