Carrier-grade solution for SD-WAN managed services
Enterprises are increasingly looking for cost-effective and simpler alternatives to WAN connectivity and sprawling branch networks. Software-defined WANs (SD-WAN) are an evolving solution that addresses many enterprise requirements around WAN costs, simplified operations and improved application performance.
For service providers building SD-WAN offerings, however, the majority of managed service operational and cost challenges can still exist — the need to deploy proprietary hardware/software at both the branch office and head-end for every end customer, as well as the lack of capability or simple integration with critical security functions like firewalls.
Versa’s VNF-based SD-WAN solution allows service providers to deliver a comprehensive, cost-effective managed SD-WAN service that includes advanced connectivity and security functions.
Based on Versa network and security VNFs, coupled with commodity hardware, the Versa SD-WAN solution includes key managed service capabilities such as multi-tenancy, multi-service, elasticity and zero-touch provisioning to maximize service agility and reduce capital and operating costs.
Building SD-WAN managed services
Increased service agility
With Versa VNFs, service providers can rapidly design a customized SD-WAN service that combines the primary network functions of application-aware routing, CGNAT and VPN, along with any incremental security functions needed – in a matter of days or weeks, not months or years as hardware-based solutions normally require.
The Versa managed SD-WAN solution has built-in service chaining to easily integrate with existing third party network and security functions in the branch office, further accelerating deployment time and agility.
Higher service revenue
With the Versa managed SD-WAN solution and its broad set of VNFs, providers can build rich SD-WAN offerings that combine networking and security to yield greater business impact than basic VPN or connectivity-only SD-WAN services.
Because Versa-based SD-WAN services utilize automatic service chaining, providers can initially sell a basic SD-WAN service to customers and up-sell security or other functions over time. The result is higher overall service revenue and customer loyalty.
Reduced service provider costs
The Versa SD-WAN solution combines software-based VNFs and low-cost commodity hardware with pay-as-you-use pricing, resulting in much lower capital costs than traditional WAN hardware or hardware-based SD-WAN solutions.
The Versa solution includes full multi-tenancy so Capex is much lower at scale, as additional SD-WAN infrastructure and management is not required at the head-end for each new customer.
Operational costs are minimized through zero-touch provisioning and centralized management, which together eliminate truck rolls and greatly simplify ongoing operations.
Differentiated SD-WAN service
Versa gives service providers the ability to create richer managed services that combine SD-WAN capabilities with a range of security functions – all using Versa VNFs.
For example, a provider can integrate SD-WAN functions with a branch-based firewall and URL filtering to create an MPLS + broadband service with secure direct Internet access to cloud apps and resources.
The result is incremental revenue, much better differentiation and less price sensitivity than connectivity-only service offerings.
