Summary:
|
As enterprise services and network resources increasingly span multiple domains, coordinated inter-domain software-defined wide area networking (SD-WAN) service becomes essential for end-to-end consistent service delivery.
Supplement 81 to ITU-T Q-series Recommendations specifies the signalling architecture, procedures and requirements for coordination between SD-WAN controllers across domains, including the interactions of resource negotiation, configuration parameters negotiation, service and network monitoring results notification, traffic steering and privacy protection negotiation. Supplement 81 to ITU-T Q-series contributes to automated provisioning and end-to-end performance assurance for inter-domain SD-WAN services.
