    Abstract: Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.

    Abstract: In a novel tunnel-less SD-WAN, when an ingress node of the SD-WAN receives a new packet flow, it identifies the path of the flow through the SD-WAN, and sends an initial prepended set of SD-WAN header values before the first packet for the flow to the next hop along this identified path, rather than encapsulating each packet of the flow with encapsulating tunnel headers that store SD-WAN next hop data for the flow. The prepended set of SD-WAN header values are then used to not only forward the first packet through the SD-WAN, but also to create records at each subsequent hop, which are then used to forward subsequent packets of the flow through the SD-WAN. Instead of identifying the entire packet flow, the first hop in the SD-WAN does not identify the entire path for the packet flow in some embodiments, but just identifies the next hop, as each subsequent hop in the SD-WAN has the task of identifying the next hop through the SD-WAN for the packet flow. Also, in some embodiments, each hop also creates records for the reverse flow in order to automatically forward reply packets along a reverse route.

    Abstract: Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.
