An example method of data protection in a virtualized computing system, the virtualized computing system including a host cluster, a virtualization management server connected, and a network manager coupled to a physical network, the host cluster having hosts and a virtualization layer executing on hardware platforms of the hosts, is described. The method includes: receiving a backup request; executing, in response to the backup request, a coupled backup of the virtualization management server and the network manager, including: creating a backup of a first database in the virtualization management server, the first database storing first configuration data for a virtual infrastructure (VI) control plane of the host cluster; creating a backup of a second database in the network manager, the second database storing second configuration data for a logical network deployed in the host cluster; and storing the coupled backup in remote storage.

Data protection for control planes in a virtualized computer system

Some embodiments provide a method for a first data compute node (DCN) operating in a public datacenter. The method receives an encryption rule from a centralized network controller. The method determines that the network encryption rule requires encryption of packets between second and third DCNs operating in the public datacenter. The method requests a first key from a secure key storage. Upon receipt of the first key, the method uses the first key and additional parameters to generate second and third keys. The method distributes the second key to the second DCN and the third key to the third DCN in the public datacenter.

Extension of network control system into public cloud

A novel method for performing replication of messages in a network that bridges one or more physical networks to an overlay logical network is provided. A physical gateway provides bridging between network nodes of a physical network and virtual machines in the overlay logical network by serving as an endpoint of the overlay logical network. The physical gateway does not replicate messages from the bridged physical network to destination endpoints in the overlay logical network directly, but instead tunnels the message-to-be-replicated to a designated tunnel endpoint in the overlay logical network. The designated tunnel endpoint in turn replicates the message that was tunneled to it to other endpoints in the overlay logical network.

Replicating broadcast, unknown-unicast, and multicast traffic in overlay logical networks bridged with physical networks

Example methods and systems are provided a network device to perform tunnel-based service insertion in a public cloud environment. An example method may comprise establishing a tunnel between the network device and a service path. The method may also comprise: in response to receiving a first encapsulated packet, identifying the service path specified by a service insertion rule; generating and sending a second encapsulated packet over the tunnel to cause the service path to process an inner packet according to one or more services. The method may further comprise: in response to receiving, from the service path via the tunnel, a third encapsulated packet that includes the inner packet processed by the service path, sending the inner packet processed by the service path, or a fourth encapsulated packet, towards a destination address of the inner packet.

Tunnel-based service insertion in public cloud environments

Some embodiments provide a method for a managed forwarding element (MFE). At the MFE, the method receives a first packet from a particular tunnel endpoint. The first packet originates from a particular data compute node associated with multiple tunnel endpoints including the particular tunnel endpoint. Based on the first packet, the method stores an association of the particular tunnel endpoint with the particular data compute node. The method uses the stored association to encapsulate subsequent packets received at the MFE and having the particular data compute node as a destination address with the particular tunnel endpoint as a destination tunnel endpoint.

Learning of tunnel endpoint selections

Some embodiments provide a centralized overlay-network cloud gateway and a set of centralized services in a transit virtual cloud network (VCN) connected to multiple other compute VCNs hosting compute nodes (VMs, containers, etc.) that are part of (belong to) the overlay network. The centralized overlay-network cloud gateway provides connectivity between compute nodes of the overlay network (e.g., a logical network spanning multiple VCNs) and compute nodes in external networks. Some embodiments use the centralized overlay-network cloud gateway to provide transitive routing (e.g., routing through a transit VCN) in the absence of direct peering between source and destination VCNs. The overlay network, of some embodiments, uses the same subnetting and default gateway address for each compute node as the cloud provider network provided by the virtual private cloud provider.

Transitive routing in public cloud

In an embodiment, a computer-implemented method for highly-scalable, in-network multicasting of statistics data is disclosed. In an embodiment, a method comprises: receiving, from an underlay controller, a match-and-action table that is indexed using one or more multicast ('MC') group identifiers and includes one or more special MC headers; detecting a packet carrying statistics data; determining whether the packet includes an MC group identifier; in response to determining that the packet includes the MC group identifier: using the MC group identifier, retrieving a special MC header, of the one or more special MC headers, from the match-and-action table; generating an encapsulated packet by encapsulating the packet with the special MC header; and providing the encapsulated packet to an interface controller for transmitting the encapsulated packet to one or more physical switches.

Highly-scalable, software-defined, in-network multicasting of load statistics data

Some embodiments provide a method of migrating a first software defined (SD) network managed by a first network manager to a second SD network managed by a second network manager. The method of some embodiments is performed by a third network manager that provides an interface that allows a set of users to specify and review logical network components, which the first and second network managers can then respectively deploy in the first and second SD networks. The third network manager in some embodiments identifies for a migration manager a first group of two or more logical network components that the third network manager previously specified for the first network manager to deploy in the first SD network. The migration manager then uses this information to correctly convert the first group of logical network components to a second group of two or more logical components in an appropriate manner that will allow the third network manager to manage the second group of logical network components that is implemented in the second SD network.

Migrating software defined network

A system and method for connecting virtual computer networks in a public cloud computing environment using a transit virtual computer network uses a cloud gateway device in the transit virtual computer network that includes a first-tier logical router and a plurality of second-tier logical routers connected to the virtual computer networks. A source Internet Protocol (IP) address of outgoing data packets from a particular virtual computer network is translated at a particular second-tier logical router of the cloud gateway device from an IP address of the particular virtual computer network to an internal IP address from a particular pool of IP addresses. The outgoing data packets are then routed to the first-tier logical router of the cloud gateway device, where the outgoing data packets are transmitted a destination network from a particular interface of the first-tier logical router of the cloud gateway device.

Connecting virtual computer networks with overlapping IP addresses using transit virtual computer network

A system and method for using private native security groups and private native firewall policy rules for a private cloud computing environment and a public cloud computing environment uses a public cloud gateway for routing data traffic between at least a cloud network created in the public cloud computing environment and the private cloud computing environment. For each of some private native firewall policy rules that has any of newly created private native security groups as one of source and destination, a cloud native security group (CNSG) rule object with an CNSG outbound rule object and an CNSG inbound rule object for the public cloud is created and at least one of the CNSG outbound rule object and the CNSG inbound rule object is updated so that the private native firewall policy rule can be used in the cloud network.

Centralized processing of north-south traffic for logical network in public cloud

Example methods are provided for a first switch to perform congestion-aware load balancing in a data center network. The method may comprise: receiving probe packets from multiple next-hop second switches that connect the first switch with a third switch via multiple paths. The method may also comprise: processing congestion state information in each probe packet to select a selected next-hop second switch from the multiple next-hop second switches, the selected next-hop second switch being associated with a least congested path from the first switch to the third switch. The method may further comprise: in response to receiving data packets from a fourth switch that are destined for a destination connected with the third switch, sending the data packets to the selected next-hop second switch such that the data packets travel to the third switch along the least congested path.

Congestion-aware load balancing in data center networks

Some embodiments provide a novel way to insert a service (e.g., a third party service) in the path of a data message flow, between two machines (e.g., two VMs, two containers, etc.) in a public cloud environment. For a particular tenant of the public cloud, some embodiments create an overlay logical network with a logical overlay address space. To perform a service on data messages of a flow between two machines, the logical overlay network passes to the public cloud's underlay network the data messages with their destination address (e.g., destination IP addresses) defined in the logical overlay network. The underlay network (e.g., an underlay default downlink gateway) is configured to pass data messages with such destination addresses (e.g., with logical overlay destination addresses) to a set of one or more service machines. The underlay network (e.g., an underlay default uplink gateway) is also configured to pass to the particular tenant's public cloud gateway the processed data messages that are received from the service machine set and that are addressed to logical overlay destination addresses. The tenant's public cloud gateway is configured to forward such data messages to a logical forwarding element of the logical network, which then handles the forwarding of the data messages to the correct destination machine.

Performing in-line service in public cloud

System and computer-implemented method for secure hybrid cloud connectivity between an application in a public cloud service and an on-premises service supported by an on-premises appliance includes launching a public cloud gateway appliance in the public cloud service. The public cloud gateway appliance is configured with security information associated with the on-premises appliance. The on-premises appliance is provided with contact information associated with the public cloud gateway appliance. A communication channel is established, using an outbound port, from the on-premises appliance to the public cloud gateway appliance that is secured based on the security information associated with the on-premises appliance and the contact information associated with the public cloud gateway appliance.
