SD-WAN(Software Defined -Wide Area Network)

sdn-wan

SD-WAN has emerged as one of the hottest topics in the WAN industry. It will become one of the key building blocks of network evolution, driving the flexibility, manageability, scalability, and cost effectiveness that organizations require in their balancing act between rapidly growing requirements and much flatter budgets.

Maintaining secure and efficient network operations for your HQ and branch locations can be complex and time consuming for both you and your IT department – regardless of how big or small your organization may be.

 

SD-WAN offers the ease of deployment, central manageability and reduced costs that organizations seek to stay competitive while continuously improving the customer experience. SD-WAN is a new simplified and more effective way of deploying hybrid WAN solutions. At the center of SD-WAN, the controller continuously monitors the network path to detect problems before they affect applications, and dynamically routes traffic to a different path if required.

SD-WAN is popular because it gives administrators the ability to control network management with software. This agility allows for better use of bandwidth by aggregating network connections and optimizing traffic for different applications. SD-WAN also provides an end-to-end solution that gives administrators a single view of the network.

It’s simple to make a strong business case for SD-WAN, since it’s a solution that’s proven its effectiveness at providing cost savings while also delivering applications quickly, reliably and securely.

The top perceived benefits of SD-WAN solutions relate directly to improvements in networking/connectivity, including better performance, improved scalability, and increased network agility.

What Type of SD-WAN Solutions Will Help Your Organization?

Organizations need SD-WAN solutions that are more than a software tool-set. At a time when applications within the enterprise are exploding and are moving to the cloud, companies are looking to SD-WAN as a genuine network solu­tion for responding to and staying ahead of the dynamic application environment that can nega­tively impact their network’s quality of service.

A solid SD-WAN solution should have the ability to dramatically enhance and accelerate an orga­nization’s ability to procure and administer their corporate network. It should provide companies with a next-generation networking solution that can better utilize network connections, reduce costs and complexity, and increase both visibility and agility.

 

Transport Scheme

Transport Scheme

SD-WAN includes the features, benefits and the associated business outcomes organizations demand, including the ability to:

  • Use MPLS for latency sensitive traffic while providing maximum bandwidth availability over public Internet connections
  • Add new locations without a lengthy deployment window
  • Support bandwidth-intensive applications and workloads
  • Increase security through encrypted WAN traffic and greater traffic visibility
  • Simplify remote office management
  • Gain more and better visibility into network use
  • Align network services to user and application needs
  • Simplify IT operations for the entire enterprise

 

WHY ARE COMPANIES SWITCHING TO SD-WAN?

Savings aside, there are many other reasons companies are switching their IT infrastructure over to SD-WAN. Here is a quick rundown of some of the other reasons the IT professionals making the switch:

  1. Security
  • Encrypting network traffic
  • Segmenting your network
  • Having a central provisioning system
  • Increasing visibility into and control of your WAN
  • Optimizing performance
  • Securing any and all transport to enterprise and Cloud data centers
  1. Centralized Orchestration
  • Central provisioning dashboard
  • Zero touch and secure deployments
  • Simplified operations
  • One-click service insertion

 

  1. Network Visibility
  • See clearly into your network to pinpoint any problem areas for a quick fix.
  • Troubleshoot without affecting your end user experience.
  1. Provider Reliability
  • Increased network visibility allows you to make sure all aspects of QoS are being honored.
  • Know if end user experience is suffering due to a problem on the provider side.
  • Builds trust, and leads to quicker fixes and a better relationship with your provider.
  1. Performance
  • Increased app performance for optimal end user experience
  • Assured application security
  • Managed on-ramp to the Cloud
  • SD-WAN provides on-premise view into Cloud applications.
  • Decrease in jitter, latency and packet loss.
  •    Jitter – A packet delay caused by variations in timing across the network
  •    Latency – How much time it takes for a packet to get from one point in your network to another
  •    Packet Loss – Failure of a packet of data to reach its designated destination
  1. Connection
  • An SD-WAN architecture is ideal for geographically-dispersed teams.
  • Increased communication speed between branches
  • Increased security of sensitive files across network
  1. Scalability
  • Scale the deployment of your WAN as you grow.
  • Hybrid options: Augmenting your current MPLS infrastructure with Broadband
  • As traffic increases, you can move applications to Cloud or restructure your WAN.

  

  1. Flexibility
  • SD-WAN working as a virtual overlay allows for hybrid solutions.
  • Dedicate some traffic to MPLS and some to SD-WAN and still decrease costs.
  • Setup your network in whatever unique way best suits your company infrastructure.
