What is SD-WAN? (SDN)

traditonal network vs sd-wanSD-WAN (software-defined WAN) is a wide area network deployment method. Using virtualization and application, SD-WAN controls and establishes WAN (wide area network) and devices across branch offices. Customers can simplify the management, configuration and maintenance of WANs with a minimal level of IT expertise. How? Secure paths are created across multiple WAN locations with zero-touch provisioning. Bandwidth can be virtually allocated and network traffic controlled from a single, centralized location.

What are the benefits of SD-WAN?

Improved cost control by paying for bandwidth based on usage
Lower financial investment in setup, management and maintenance of WAN equipment
Reduced workforce expenses with limited or no IT personnel off-site
Faster provisioning times and increased branch uptime/availability
Ability to manage network traffic from a single control source
Greater security and visibility for WAN traffic

Gartner predicts by 2018, 10% of enterprises will have replaced

their WAN routing with SD-WAN based path forwarding, up from less than 1% today

  • Are You A Potential Customer For SD-WAN? 

    Curious if SD-WAN will work for you? Answering Yes to at least one of the following points most likely means that SD-WAN is a perfect fit for your company.

    Managing WAN/MPLS connectivity in-house for multiple locations with a high cost of connectivity caused by WAN transport, equipment and personnel expenses
    Hassle of complex devices and hardware updates with slow provisioning of network resources and traffic congestion
    Inadequate level of network performance for emerging cloud computing with difficulty in adapting or scaling to developing business needs
    Interested in optimizing performance of cloud-based applications such as SalesForce, Office 365 and hosted voice or e-commerce business
    Open to refreshing WAN equipment and improving network connectivity
    Looking for security intelligence built into network (vs. purchasing separately)


The Benefits of SD-WAN

Not your traditional QoS, this application prioritization is even more relevant to current businesses and sales conversations. Why? Because end users don’t use data packets – they use applications, and SD-WAN enables the optimization of the applications used on a daily basis. You essentially create a stack ranking of all the applications on the network, sorted by the importance of their performance to the business. Once sorted, the network enforces these ranking – inclusive of all the different types of data packets that are transported through the use of the application. These rankings can be changed on the fly or reprioritized on a schedule depending on other network events.
Nevertheless, it is important to understand the difference between QoS with SD-WAN vs. QoS with MPLS where it is relegated to prioritizing types of data packets- namely video, voice, critical data, and non-critical data – essentially offering you four distinctions with which to manage the network.
  • Furthermore, with SD-WAN you can improve network congestion through the incorporation of multiple circuits and management of the traffic flow. The overlay also allows users to set application-level routing profiles to prioritize mission-critical data down to the application layer while providing QoS on individual applications. Users then streamline performance through packet steering across multiple connections, allowing for load balancing in the event of circuit degradation or critical failure. User can also further improve performance and continuity with the incorporation of secondary and tertiary connections for more failover options from any access technology.

  • SD-WAN gives businesses the ability to deploy new locations quickly. Whether you are using current access technologies or the site has simply been replicated from an existing location, you can avoid a number of provisioning headaches. Depending on the SD-WAN carrier, deployment can be as simple as plug and play. Provisioning is another convenience with SD-WAN because of the streamlined network adjustments through the orchestration layer – oftentimes from an online management portal – and can be executed quickly from HQ. As a result, customers can better allocate network resources during periods of high traffic.

  • Improve your network with greater visibility into traffic patterns and connection monitoring. Depending on the SD-WAN provider, many analytics features – from usage capacity to network behaviors of end users (down to the application) – are included and visible in the provider’s portal.

Key Verticals For SD-WAN
  • Finance & Banking

    1 – Strict compliance and regulation on the industry
    2 – Lack of IT support at the branch
    3 – Standard operating procedures are bandwidth-heavy and occur at regular, predictable intervals
    4 – Performance can be streamlined down to the application layer and URL through packet steering and application-aware routing for all employee and customer activity on the network.
  • Manufacturing

    1 – Bandwidth-heavy machinery needs to be prioritized on a secure network for peak performance
    2 – As the number of end points increases (IoT), SD-WAN can provide the network visibility to effectively manage them
  • Healthcare

    1 – HIPAA and other compliance and regulatory requirements on the industry
    2 – High uptime requirements to enable care givers and physicians access to important medical records for patients
    3 – Large file transfers and high egress traffic is not cost effective on MPLS circuits
  • Retail

    1 – Strict compliance and regulation on the industry
    2 – Lack of IT support at the branch
    3 – Standard operating procedures are bandwidth-heavy and occur at regular, predictable intervals
    4 – Streamlined performance down to the application layer, even URL, through packet steering and application aware routing for all employee and customer activity on the network
