A Better Architecture for Hybrid WAN - VeloCloud

Download to read offline

Most enterprises deploy both private MPLS and public broadband Internet to some or all of their branch offices. The right SD-WAN solution will dramatically improve the utilization, performance and ease of management of the these hybrid deployments.

Review this presentation for a detailed understanding of the architectural details of Cloud-Delivered SD-WAN for hybrid WAN deployments. You’ll leave with a clear understanding of how hybrid deployments can be designed, implemented and maintained for a secure, optimal and high quality wide area network.
