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:
Systems for and methods of modelling, analyzing and managing data networks are provided. In an embodiment, a plurality of network device interfaces are configured to collect state information for a plurality of network devices. A computer-implemented model of the network comprises a data structure, which may be graph-based. The data structure comprises a plurality of snapshots of the network, each snapshot representing the network at a particular point in time, and the data structure comprises a representation of possible data flow and data packet processing within the network. The data structure contains normalized representations of the network devices corresponding to the location. The normalized representation for each device contains a set of packet processing rules. A user-interface is configured to receive queries from a user that request verification of network policies and predictions of network behavior. The user-interface is configured to display responses to the queries that are obtained using the data structure.

Application number: 17/537,415

Abstract:
A runtime state of a virtual port associated with a virtual machine (“VM”) is persisted as the VM is migrated from a source host to a destination host. In certain embodiments, a virtual switch forwards network frames between the VM and the physical network interface via the virtual port. During migration of the VM, the runtime state of the virtual port is transferred to the destination host and applied at the second host to a virtual port associated with a second virtual switch at the destination host. The runtime state of the virtual port at the source host is then cleared, and the second virtual switch at the destination host forwards network frames between the migrated VM and the physical network interface of the destination host using the virtual port at the second host.
