NBS offers redundant WAN solutions to eliminate the single point of failure in customer networks, particularly focusing on voice, MPLS, and DIA services. Three options are available: on-net to on-net redundancy, on-net to VPN redundancy, and on-net to third-party DIA, each providing varying levels of service and reliability. These solutions leverage diverse carriers and automatic failover capabilities to ensure uninterrupted connectivity during network disruptions.
Fusion Auto Failover/Redundant WAN Solutions
- 1. NBS Auto Failover solutions 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 NBS Auto Failover Solutions are on external access to their site/network from the Internet, as the customer’s offered with three varying levels of public LAN IP addresses will also route over the failover circuit. service to meet the diverse technical 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 ON-NET to ON-NET: for the redundant links. The Off-Net access can be almost any type of circuit • Near Instantaneous Failover Time (Ethernet/T1/DS3/DSL/Cable/3G/4G). An IPSec VPN tunnel is overlaid on • NBS Implemented & Managed the off-net DIA to establish a secure WAN connection back to the NBS IP/ • QoS On Backup Circuit MPLS network. Between the CPE and the NBS routers automatic failover is configured by utilizing a dynamic routing protocol. This protocol handles the ON-NET to VPN: re-routing of customer traffic over the backup link upon primary link failover. The process is fully automated and not only provides VoICE, DIA and MPLS • IPSec VPN Tunnel Access services, but is also ideal for customers who rely on external access to their • Public IP Addresses Continue To Be network from the Internet as the customer’s public LAN IP addresses will also Accessible From Internet route over the failover circuit (e.g. if the customer hosts their own website it will still be accessible to the outside world via the failover connection). ON-NET to 3rd PARTY DIA: • Fully Automatic Failover On-Net To 3rd Party DIA Redundancy The last option utilizes one NBS On-Net circuit and one Off-Net Internet access • NBS Implemented & Managed circuit. Again, the Off-Net access can be almost any type of access circuit • Voice & Internet Continue To (Ethernet/T1/DS3/DSL/Cable/3G/4G). As with On-Net to VPN Redundancy, 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- 155 Willowbrook Blvd. available, but does not require external access to their site.
