 “Help me Obi-Wan Kenobi, you’re my only hope.” These eight words are some of the most famous in cinematic history. They brought audiences into a new galaxy and introduced some beloved (and not so beloved) characters into our culture. I recently watched “Star Wars: A New Hope” and was struck by the similarities between the character struggles and those faced by WAN data traffic overloading. Obi-SD-WAN-Can-o-Be. Is there hope for escalating WAN circuit costs?”

 As organizations become more reliant on SaaS solutions like Microsoft Office 365, cloud back-ups, and cloud hosted applications, they are discovering their WAN data traffic and costs are growing at an alarming rate.  To address this issue, companies are deploying Software Defined WANs (SD-WAN) as a solution to reigning in the growth of MPLS spending on WAN connections. Learn how Micro Focus Network Operations Management (NOM) delivers extended management over this key new use case using the new driver for Viptela vEdge SD-WAN Routers.

Viptela vEdge SD-WAN Routers

One of the strongest use cases in Software Defined Networking (SDN) today centers around SD-WAN.  Company’s deploying SD-WAN routers are able to overlay one or more logical WANs over a pool of connections.  This structure commonly provides the flexibility to optimize traffic based on link performance and service levels.  Once deployed, many have been able to evaluate and remove costly and unnecessary WAN circuits, reducing costs and achieving the ROI required to implement the SD-WAN solution.

One of the leading vendors for SD-WAN is Viptela—recently acquired by Cisco.  The Viptela vEdge line of SD-WAN routers supports multiple connections to the WAN including:

  • MPLS
  • Ethernet
  • SSL over Internet
  • IPsec connections

Note: The vEdge-100-B, is a solution for a small remote office.  The vEdge-1000 is capable of higher throughput making it a better candidate for data centers and larger branch offices.

In our continuing effort to support the latest vendors and devices on the network market, the latest driver pack for the Micro Focus Network Operation Management (NOM) Suite now supports extended monitoring and configuration management for these Viptela routers.  This extended support goes far beyond what is normally available via the SNMP interface. 

The advantage of SD-WAN and Micro Focus NOM

To many network engineers and operators, SDN is synonymous with “complex”.  However, to the companies that are deploying SD-WAN, they see it as the solution to reigning in the growth of MPLS spending on WAN connections.   

As organizations become more reliant on SaaS solutions like Microsoft Office 365, cloud back-ups, and cloud hosted applications, they are discovering their WAN data traffic and costs are growing at an alarming rate.  Some have reported seeing WAN data volumes double in the span of six months!  The standard response to their growth of simply purchasing more capacity on their existing MPLS circuits is unsustainable.  And it is important to note that not all applications require the quality that MPLS provides.

However, if they could intelligently route their WAN traffic based on the performance, costs, and service levels (SLA) required by specific applications—significant cost savings can be realized.  For example, as traffic is routed to lower cost internet circuits, the dependency on expensive MPLS bandwidth is reduced or potentially eliminated. 

The advantage of Micro Focus Driver for Viptela SD-WAN Routers

Micro Focus typically provides device driver packs for the NOM Suite on a bi-monthly. This goal is key to our continuing effort to support the latest vendors in the networking market.  Each update adds to the industry leading 180+ supported vendors and 3,400+ supported devices already part of the suite.

Many network monitoring tools are limited to only what is available through SNMP and simple ICMP-ping—examples include discovery and uptime.  With the new Micro Focus NOM driver for the Viptela vEdge SD-WAN routers, users can also:

  • Automate the deployment of configurations to their SD-WAN routers to implement their intelligent routing polices.
  • Detect and mitigate unauthorized changes to the policies on their SD-WAN routers that impact performance or costs.
  • Parse and diagnosis issues directly from the SysLogs on their SD-WAN routers to be alerted when configurations are changed.

What does this mean in Micro Focus NOM suite?

Let’s consider a scenario that demonstrates the benefit of the Micro Focus NOM suite using the new driver for the Viptela vEdge SD-WAN routers.

Let’s presume a company has deployed a new high-priority internal application in a remote data center.  This application requires a low-latency network connection to a second data center via an MPLS circuit. The operator used Micro Focus NOM suite to configure a Viptela SD-WAN router to route the applications traffic over the MPLS circuit, while routing all other traffic over a secondary circuit.  This configuration provides the best performance at the lowest cost. 

The operator is relying on Micro Focus NOM to monitor the latency of the MPLS circuit with IP SLA. When the latency is too high, NOM can be configured to automatically re-configure the Viptela SD-WAN Router to reroute the traffic for the application over the secondary circuit to keep it functioning.  Once the latency on the MPLS network is back to the desired performance level, NOM will then reconfigure the Viptela router to again route the high-priority traffic over the MPLS circuit as normal.

The end result is the NOM suite simplified the process of routing the high-priority application traffic through the Viptela SD-WAN router while also ensuring application up-time.

In Summary

Managing your Viptela SD-WAN Router with Micro Focus NOM suite helps users realize the true value of the SD-WAN through a single SDN management solution.  For more information on the Micro Focus NOM Suite, please explore the Vivit webinar, slide deck and solution brief: Introducing the Network Operations Management Suite from Micro Focus.
