    Abstract: The disclosure provides an approach for seamless hand-off of data traffic in public cloud environments. Techniques are provided for activating an edge services gateway (ESG) virtual computing instance (VCI) on a new host. Prior to activating the ESG VCI on the new host, an underlay routing table is reprogrammed to associate a first IP address of a first tunnel endpoint (TEP) with a first network interface of an old host and to associate a second IP address of a second TEP with a second network interface of the new host. The routing table associates a third IP address of the ESG VCI with the first network interface. After activating the ESG VCI, a packet having as a destination address the third IP address is received at the first network interface and is encapsulated, by the first TEP, with an outer header having as a destination address the second IP address.

    Abstract: Some embodiments provide policy-driven methods for deploying edge forwarding elements in a public or private SDDC for tenants or applications. For instance, the method of some embodiments allows administrators to create different traffic groups for different applications and/or tenants, deploys edge forwarding elements for the different traffic groups, and configures forwarding elements in the SDDC to direct data message flows of the applications and/or tenants through the edge forwarding elements deployed for them. The policy-driven method of some embodiments also dynamically deploys edge forwarding elements in the SDDC for applications and/or tenants after detecting the need for the edge forwarding elements based on monitored traffic flow conditions.

    Abstract: Some embodiments provide a method for deploying edge forwarding elements in a public or private software defined datacenter (SDDC). For an entity, the method deploys a default first edge forwarding element to process data message flows between machines of the entity in a first network of the SDDC and machines external to the first network of the SDDC. The method subsequently receives a request to allocate more bandwidth to a first set of the data message flows entering or exiting the first network of the SDDC. In response, the method deploys a second edge forwarding element to process the first set of data message flows of the entity in order to allocate more bandwidth to the first set of the data message flows, while continuing to process a second set of data message flows of the entity through the default first edge node. The method in some embodiments receives the request for more bandwidth by first receiving a request to create a traffic group and then receiving a list of network addresses that are associated with the traffic group. In some embodiments, the method receives the list of network addresses associated with the traffic group by receiving a prefix of network addresses and receiving a request to associate the prefix of network addresses with the traffic group. Based on this request, the method then creates an association between the traffic group and the received prefix of network addresses.

    Abstract: Some embodiments provide a method for proxying ARP requests. At an MFE that executes on a host computer operating at a first site to implement a distributed router along with at least one additional MFE at the first site, the method receives, from a router at a remote second site, an ARP request for an IP address associated with a logical switch that spans the first site and the remote second site, and to which both the distributed router and the router at the remote second site connect. The method determines whether a table that includes IP addresses for a set of DCNs that use the distributed router as a default gateway includes the IP address. When the IP address is in the table, the method proxies the request at the host computer. When the particular IP address is not in the table, the MFE does not proxy the request.
