Abstract
A method comprising instantiating virtual routers (VRs) at each of a set of nodes that form a network. Each VR is coupled to the network and to a tenant of the node. The network comprises virtual links in an overlay network provisioned over an underlay network including servers of a public network. The method comprises configuring at least one VR to include a feedback control system comprising at least one objective function that characterizes the network. The method comprises configuring the VR to receive link state data of a set of virtual links of the virtual links, and control routing of a tenant traffic flow of each tenant according to a best route of the network determined by the at least one objective function using the link state data.
