SD-WAN solutions can offer improvements over traditional WAN offerings in the right circumstances.
Reduce the need for multiple network devices and seamlessly combine WAN technologies.
Application profiling allows network traffic to be more easily prioritised down to individual application across all locations. Some devices allow traffic to overflow to other WAN links, making use of all available bandwidth.
Depending on the connectivity at each location, SD-WAN can use less expensive internet connections and add bandwidth compression to offer more value than MPLS.
By combining cheaper internet links (potentially in combination with MPLS), SD-WAN can also provide improved failover between different connections including fibre, NBN, copper, and 4G.
Not all SD-WANs are equal
Vendors have approached SD-WAN differently. Some are a development of traditional firewalls (Meraki, Fortinet), whereas Cato Networks is essentially a multi-tenanted global WAN which each site connects to. Knowing which SD-WAN is best suited for your connectivity needs is critical.
The team at First Focus have developed a strong relationship with Rexel Holdings Australia which has led to us outsourcing a number of services to them, the largest of which is the SD-WAN. The First Focus team are collaborative and engage extremely well with our team and our extended partner network to deliver quality outcomes.
