Abstract

A method supports service level agreement monitoring in a software defined network. The software defined network has forwarding elements and a software defined network controller for controlling the forwarding elements. Data flows are transmitted between a first end-path forwarding element, of the forwarding elements, and a second end-path forwarding element, of the forwarding elements, via at least one intermediate forwarding element, of the forwarding elements. The software defined network controller configures the intermediate forwarding element such that a probe triggering packet is generated based on local information of the intermediate forwarding element. The software defined network controller configures at least one of the first end-path forwarding element or the second end-path forwarding element such that an end-to-end probing is triggered based on receiving the probe triggering packet. The end-to-end probing is performed in order to detect a service level agreement violation.
