One of the first customer-facing applications of SDN is the software-defined WAN (SD-WAN).
SD-WANs provide end-user organisations with greater bandwidth and more flexibility than conventional WAN services. Some service providers (and their larger customers) are using SD-WAN to provide and manage connectivity to other groups within their own organization.
With the potential for greater variation, it’s important to ensure that use of the SD-WAN is optimized. And with SD-WAN supporting business-critical functions, it’s also important to ensure that in the event of failures, the network can rapidly self-heal to maintain service levels.
Aria SD-WAN Optimization
Aria’s SD-WAN optimizer models complex networks to deliver an overview of network and traffic in a number of different scenarios, predictive and in near real time. It integrates fully into the operator’s OSS business processes, delivering seamless network orchestration and management across the entire network and enabling a far richer oversight of service delivery performance and capacity utilization.
Uniquely, Aria Networks SD-WAN optimizer works across all network layers and technologies including multi-vendor networks, providing optimization across even the most complex network architectures.
As networks look to embrace SDN, the SD-WAN optimizer is a critical step on the journey to delivering a more efficient and profitable network against an ever increasing demand for data services across heterogeneous networks.
As part of a proof-of-concept, a European tier one used Aria to optimize the SD-WAN portion of their global network to deliver improved Quality of Service (QoS), automated repair of failure and network optimization across all network layers and technologies.
The global service provider used Aria’s SD-WAN optimizer to support:
- network planning
- traffic orchestration
- optimization of resource utilization for best quality and highest profitable service delivery.
Applications include improved oversight of where and when to carry out planned engineering works, the impact that these will have on service provision, financial performance and oversight of potential network vulnerabilities. This allows the service provider to significantly reduce downtime and improve service levels.
In addition, Aria Networks’ SD-WAN optimizer showed how to reduce network reduce response times to failure to less than five minutes and enables the network to carry out automated repairs that take into account improved QoS.
