Abstract: Aspects of the present disclosure are directed to dynamic adjustment of load-balancing weights across multiple network transport interfaces in a network, informed in part by Quality of Service (QoS) metrics. In one aspect, a method includes determining one or more metrics based on one or more Software-defined Wide Area Network (SDWAN) session level throughput and SDWAN session loss through one or more tunnels; generating a Quality of Service (QoS) SDWAN session level shape rate per tunnel based on the one or more metrics; and dynamically adjusting an SDWAN forwarding load-balance weight for each of the one or more tunnels based on the QoS SDWAN session level shape rate.

Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for simulating traffic flow in a virtualized network fabric. A method includes: creating in a visualization tool one or more virtual network hubs, one or more virtual branch locations, and one or more virtual internet servers; generating one or more micro-probes for clients/servers to be simulated, one or more of the clients/servers is located in each of the one or more virtual network hubs, virtual branch locations, and the virtual internet servers; generating one or more network impairments, which are associated with one or more of the one or more of network hubs, branch locations, and/or internet server locations; and launching one or more, client-role or server-role traffic invokers in each micro-probe to simulate traffic between the one or more of the virtual network hubs, the virtual branch locations, and/or the virtual internet server.
