Centralised management . Facilitating the management , maintenance , and operation of Edges and 5G cells by intelligently rerouting traffic during provisions and upgrades . When enterprises deploy new applications or when a security policy change is necessary , a business-driven SD-WAN enables these changes to be delivered in minutes , while simultaneously minimising the opportunity for human error .

Machine Learning . Automation is key . It is vital that any SD-WAN vendor guarantees that their network can adapt to varying conditions in real-time and provide optimal routing to the Edges and 5G cells . intelligent routing , with each class of application receiving the appropriate Quality of Service ( QoS ) and security policy enforcement . This quality is vital in the enablement of 5G . Through SD-WAN ’ s ability to incorporate Machine Learning , it enables networks to adapt to varying circumstances and automatically route high-bandwidth traffic to 5G cells and the edge . Ensuring high quality user experience for 5G is paramount , therefore it is vital that service providers evaluate SD-WAN vendors on the following :
Security integration with business-intent networking . Cybersecurity is an ever-present issue . By directing traffic to the right security services and enabling application-driven security policies enforced from a centralised position , service providers will not have to compromise on either cost or performance .
Virtual WAN overlays . Quality of service is hugely important , and network resources must be flexible , and optimised . 5G networks depend on network slicing , whereby each slice receives a unique set of resources . By using both technologies in combination , service providers can steer critical traffic to the 5G network where it can be isolated to a particular slice depending on its specific requirements .
Granular , intelligent application-driven routing . The ability to automatically prioritise traffic based on bandwidth should be a key area of concern . Lower bandwidth traffic should be routed to other available transport such as LTE or broadband , allowing for high-bandwidth traffic like video streaming to be routed through a 5G cell .
As 5G and Edge Computing adoption increases , so too will the demands of users . Service providers must be ready to provide an ever-present and high performing network . The initial success of 5G deployment will demand a network that has automation and security at the centre of its operation , like the one offered by SD-WAN . p
