Software Defined WAN (Wide Area Network)
Over the past five years there have been significant advancements in increasing the level of agility and flexibility in the data center through software defined networking (SDN). However, one part of IT that has yet to evolve and lacks flexibility is the enterprise wide-area network (WAN).
Evolving the WAN must be at the top of every IT and business leader’s priority list because organizations can only be as agile as their least agile IT component—which, today, is the WAN. If businesses are going to ever reach the level of agility required to compete in today’s digital world, now is the time for the WAN to evolve into a Software-Defined WAN (SD-WAN).
Dynamic Multipath OptimizationTM
Aggregate broadband Internet, 4G-LTE, and MPLS circuits with application-aware per-packet link steering and on-demand remediation to achieve optimal performance for demanding, real-time voice and video over any transport.
Economically increase bandwidth by aggregating WAN circuits of any type, providing faster response even for single application flows. Virtualization and automated configuration enables bandwidth elasticity and provider flexibility.
Active-active mechanism based on link performance provides protection against blackouts and brownouts with sub-second failover. Provider and physical link diversity ensures high availability.
Cloud Application Quality
Direct yet optimized branch-to-cloud application performance is enabled with the SD-WAN overlay to distributed gateway services throughout the cloud.
The right SD-WAN solution is inherently flexible, scalable, and adaptable. A SD-WAN platform should be designed to be complementary, or sometimes, as an alternative or replacement to an MPLS platform, and it needs to break the restrictive chains imposed by MPLS.
A primary goal of SD-WAN is to eliminate a differentiation between “branches” or “remote locations” from main offices, transforming the entire organization into a completely unified enterprise where the service experience is optimized and the same for everyone, regardless of location or proximity to services. This mandates architectural flexibility to accommodate all possible permutations of network infrastructure and service availability.
Growth strategies should also be supported. Enterprises often will acquire new companies or additional sites that require network modifications to integrate into the overall corporate network environment. A strong SD-WAN solution will quickly adapt and scale to support additional edges and network demands.
