Abstract: A system comprising nodes configured to form a network including virtual links in an overlay network provisioned over an underlay network. The system includes tenant networks formed in the network, and each tenant network corresponds to a tenant of the network. The system includes control planes, and each control plane is a component of a tenant network and includes routing algorithms corresponding to traffic classes. The tenant network is configured to use feedback data of link conditions of the tenant network with at least one routing algorithm to control routing of tenant traffic of a corresponding traffic class.

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.
