Simplify your branch office network with optimized application performance using SD-WAN

Today’s enterprise IT has become more sophisticated and bandwidth intensive, creating a complex and bogged down network environment. These challenges stem from organizations relying heavily on cloud-based applications for video streaming, large file transfers, collaboration tools and other performance heavy activities. Then, to add in the mix, branch offices are geographically spread and need reliable, high-performance network connections just like their headquarters.

IT departments providing network WAN (wide area network) access, such as MPLS (Multiprotocol Label Switching), to multiple locations face major challenges with complexity, performance, cost and security. Traditional WAN technologies have changed little since the 1990s and fail to integrate into the cloud, the vast amounts of “as a service” solutions and virtualization. These factors can lead to challenges for IT departments and their branch locations:


  • Network management – WANs connect headquarters and branch locations that are geographically dispersed with business applications located in data centers over a singular network. WANs traditionally require multiple devices that have their own function to make the network work properly. These devices, in multiple locations, create a web of complex procedures, alerts and areas of failure for IT departments to manage.
  • Risk mitigation – Protecting a business environment from the vast number of threats should be top of mind for all IT departments, but it doesn’t come easy, especially if you are integrating public internet into a WAN. Identifying and mitigating risks can become nearly impossible for teams.
  • Cloud adoption – Cloud adoption is creating a high-bandwidth network that private circuits and traditional network architectures were never designed to support. When the network gets congested, packet loss occurs creating latency and application performance issues.
  • Increasing traffic volume over traditional solutions – MPLS is a private network that is traditionally more expensive than public internet. Not all branch locations can justify the use of premium MPLS though. Therefore, organizations are deploying hybrid networks that are reserving MPLS for higher business priority and using internet for other traffic. While more mission-critical workloads are happening in the cloud, more traffic is becoming a business priority and driving up costs.
  • Branch network deployments – With complex environments, branch network deployments can become tricky. This is especially true if you don’t have IT staff members in branch locations that know how to properly deploy and manage a network. Deployments can become delayed due to IT complexity and installation wait time.
  • New application adoption – Most companies are utilizing cloud applications today, and it is only going to increase as more organizations trust the cloud with priority workloads. Performance and user friendliness can be impacted if you don’t have the efficient connections needed.


To overcome these challenges, organizations are utilizing cloud-based SD-WAN to provide enterprise-grade performance, visibility and control over internet broadband and private circuits. SD-WAN combines the economies of utilizing underlying access technologies to make the network more cost-effective while enhancing deployment, management and cloud functionality. Virtualized services are now delivered from the cloud to branch offices and remote users to simplify WAN.

Application performance is dramatically improved because WAN traffic is automatically in real-time steered across the best links and most optimal paths to improve user experience and quality. When traffic with higher business priority is identified, forward error correction (the use of redundant data to enhance data reliability) is performed to reduce and eliminate packet loss  to increase application performance and voice quality.

With multiple types of deployments and customized solutions for routing connections, SD-WAN overcomes the sophisticated network challenges businesses face today. It’s ability to allow multiple links, devices and services to co-exist and interoperate together in the cloud assures quality voice and critical application performance. Even better, organizations can open new locations efficiently with zero-touch deployment, integrate diverse infrastructures as well as ensure security.
