Publication number: 20230362086Abstract: 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.Type: ApplicationFiled: July 17, 2023Publication date: November 9, 2023Inventors: Nithin Michael, Ao Tang, Victor de Souza Lima e Silva, Thiago Sousa Santos, Ning Wu, Archit Baweja, Ki Suh Lee, Yao Wang, Andrey Gushchin, Sakethnath Are

Publication number: 20230362087Abstract: Embodiments disclosed include a method and apparatus for global traffic control and optimization for software-defined networks. In an embodiment, data traffic is optimized by distributing predefined metrics (data traffic information) to all controllers in the network. The predefined metrics are specific to local network switches and controllers, but are distributed to all peers at configurable intervals. “Local” as used herein implies one POP and its associated switch and controller. The method of distribution of local POP metrics is strictly in band using a packet as defined by the protocol used by the data network.Type: ApplicationFiled: July 17, 2023Publication date: November 9, 2023Inventors: Victor de Souza Lima e Silva, Archit Baweja, Nithin Michael
