Along with expanding their virtual private network (VPN) and virtual desktop infrastructure (VDI) deployments to assure reliable business service access for at-home workers, many enterprises are turning to software-defined WAN (SD-WAN) solutions to overcome costs, complexity, and performance associated with traditional hardware-based WAN operations in vast remote-office networks.
Even prior to its own work-from-home employee transition in response to the COVID-10 pandemic, a leading manufacturer had experienced exponential remote-office network changes, with an increase from 50 sites to hundreds of locations.
Wanting to convert from its hardware-based WAN to SD-WAN with an approach involving a lightweight footprint in a zero-touch deployment, IT leadership identified an SD-WAN solution involving VMware (VeloCloud SD-WAN, VMware ESXi hypervisor, vRealize Network Insight, and VeloCloud Orchestrator) as well as universal customer premise equipment (uCPE) and virtual network function (VNF) vendor solutions.
During predeployment, the IT team encountered an issue they didn’t anticipate: the Avaya VoIP application used for voice service delivery in remote offices was sensitive to data transfer processes on SD-WAN.
Learn how this manufacturer used NETSCOUT virtual visibility and unified communications (UC) analytics to assure SD-WAN conversion success and delivery of uninterrupted business services to remote-office workers during this high-profile project.
