Abstract: A system comprising nodes coupled to a network including virtual links in an overlay network provisioned over an underlay network. The system includes a virtual machine (VM) provisioned at a node and coupled to the network. The VM is configured to receive feedback data of link conditions, and use the feedback data to dynamically determine and adapt an optimal route through the network. The VM is configured to control routing of traffic flows using the optimal route. The routing includes split routing of a traffic flow from the node via two or more of the virtual links.

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.

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 system of nodes configured to form a network comprising virtual links in an overlay network provisioned over an underlay network including servers of a public network. The system includes virtual routers (VRs) at each node. Each VR is coupled to the network and to a tenant of the node, and configured to form in the network a set of virtual links corresponding to the tenant. One or more VRs includes a feedback control system comprising an objective function that characterizes the network. The VR is configured to receive link state data of the set of virtual links and control routing of a tenant traffic flow of each tenant according to a best route of the network determined by the objective function using the link state data.
