Fusion combines physical redundancy and diversity with our network-based intelligent routing solutions for a reliable and fully automated failover solution that can be implemented during network-impacting events to ensure a positive user experience. WAN redundancy options for customers who require highly-available Voice, MPLS, and Direct Internet Access (DIA) services

Redundant WAN Service
For Business
NBS offers several WAN redundancy options for customers who require VoICE, MPLS,
or DIA services. While the NBS network is engineered to exceed all SLA targets, the
characteristic failure point for any customer network is the local access circuit. Our
redundant WAN solution allows customers to eliminate this single point of failure from
their network without assuming the financial and technological burden of a complex,
multi-carrier solution. By leveraging NBS’ extensive portfolio of carrier-partners
our customers are able to install redundant circuits to any location utilizing diverse
underlying carriers and access mediums.
By combining this physical redundancy and diversity with our network-based
intelligent routing solutions, a reliable, fully automated failover solution can be
implemented during network-impacting events. Our standard offering includes
three options that provide varying levels of service to meet a diverse range of
customer requirements. These application-specific solutions are engineered to
provide an unparalleled level of network reliability for any situation.
We work with our customers to choose the correct solution, oversee its
implementation and testing, and manage the service throughout its lifetime.
This eliminates the costly and time-consuming need for an outside consultant to
provide and manage this solution.

2. Redundancy/Auto Failover
Three Options To Consider
On-Net To On-Net Redundancy
This option utilizes two NBS On-Net circuits for the redundant WAN links.
These circuits are ideally provisioned from diverse network providers and
to diverse NBS Points of Presence (POPs). By coordinating the CPE and the
Provider Edge routers, automatic failover is configured utilizing a dynamic
routing protocol. This protocol handles the re-routing of customer traffic over
the backup link upon primary link failure, and back to the primary link upon
service restoration. This process is fully automated and can be completed in
less than one second. Since both circuits are On-Net to NBS, we are able to
maintain the same Quality of Service (QoS) across both links. This option is
ideal for NBS VoICE, MPLS and DIA customers, as well as customers who rely

and financial needs of our clients.
On-Net To VPN Redundancy
This option provides additional access circuit flexibility to our customers. It
utilizes one NBS On-Net circuit and one Off-Net IPSec VPN tunnel access

Function During Network Event this option provides a diverse physical path. Where this solution differs from
the previous one is in both the method of failover and the services that are
maintained over the redundant path. Failover here is achieved using the
Cisco SLA feature on the CPE. The CPE actively monitors the state of the
primary circuit, and upon detection of a failure will begin routing traffic over
the Off-Net DIA. It then performs Network Address Translation off your NBS-
assigned public IP addresses to the 3rd party provider’s public IP address.
This process is fully automated and provides for Internet access as well as
NBS VoICE services to the fail over. This solution is ideally suited for the SMB
customer that requires their NBS VoICE and Internet access to be highly-
