Digital transformation and cloud computing have prompted software-defined wide-area networking (SD-WAN) to replace the traditional WAN for remote and branch office deployments. While SD-WAN provides many benefits, the ability to effectively orchestrate the multitude of efficient data flows that SD-WAN delivers is becoming critical.
At the heart of every modern SD-WAN solution is a centralised management system called a service orchestrator that “orchestrates” traffic and optimises the available bandwidth. A service orchestrator also manages the SD-WAN service lifecycle, including fulfilment, analytics, performance monitoring, security, and policy management.
We’ve selected 7 market-leading SD-WAN providers and present an overview of the main features of their orchestrator offerings.

What Is SD-WAN?
In simple terms, SD-WAN is a software-driven WAN solution that enhances WAN connectivity between sites. As stated earlier, SD-WAN employs a cost-effective mix of direct-to-the-internet broadband, LTE, 4G, and 5G WAN connectivity to connect data centres and local branch sites.
These connections are encrypted, and administrators can prioritise specific traffic/application types across numerous lines and at every site. SD-WAN allows enterprises to expand their network across any distance and deliver essential services at a reduced cost.
A centralised management system orchestrates the traffic flows and ensures optimised use of available bandwidth. SD-WAN can also monitor each WAN circuit for load times and delays and direct traffic accordingly.
What Is SD-WAN Orchestrator?
Perhaps the most significant advantage of modern WAN services is that the orchestration and delivery of these services can be aided by software. Thus, SD-WAN connectivity is delivered as a service using software orchestration.
SD-WAN can deliver enterprise services such as Virtual Private Networks (VPNs), WAN acceleration, and bandwidth optimisation. By using Commodity Off-The-Shelf (COTS) hardware in branch offices, SD-WAN as a service using orchestration can be delivered with virtual customer premises (vCPE) or light CPE equipment.
In order to deliver a robust SD-WAN solution, service providers, including Securus, uses an orchestration platform to manage the service in the most granular way possible. A combination of Software Defined Networking (SDN) controller and network virtualisation software enables automation for the provisioning and operation of a highly developed WAN infrastructure for head office, branched, hubs sites, and remote workers.
The SDN controller is the brain of the platform that oversees the network. When combined with the other virtualised network components, the SDN controller works as a Virtualised Infrastructure Manager (VIM) and manages network resources.
The orchestrator also manages service chaining, which involves several services or applications working together. They are linked from a data centre to supply the customer with the specific combination of services they need. Service chaining connects virtual network functions (VNFs) like a VIM to perform Network Function Virtualisation (NFV).
Another goal of SD-WAN orchestration is to enable customer provisioning. With it, a customer accesses a web portal and orders services, which are then automatically configured and delivered with the SD-WAN platform. All associated tasks are automated and require no human action. Instead, it requires only the aid of interoperable SD-WAN tools and protocols, including Application Programming Interfaces (APIs) and automated configuration standards.

Who Do We Recommend?
As with most network requirements, one size does not fit all, and each vendor offers a different set of features on their SD-WAN underlay, overlay, and orchestrator. In general, we recommend either Fortinet or Silver-Peak (HPE) for small to medium-sized SD-WAN deployments. Cisco, Versa and VMWare are more suitable for large-scale SD-WAN deployments. Oracle and Citrix are recommended for highly scalable cloud-hosted SD-WAN orchestrator solutions.
