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: In some embodiments, a method configures, at a first host, an overlay channel for sending packets to check whether a failure has occurred at a workload. The first host and a second host are connected via a layer 3 network. The first host generates a packet to check whether the failure has occurred at the workload and encapsulates the packet. The first host sends the encapsulated packet to the second host using the overlay channel via the layer 3 network. The packet is decapsulated and forwarded to the workload at the second host.

Abstract: In some embodiments, a method adds a specific route for an IP address that is associated with a first workload into a routing table for a first network device in a first site in response to the first workload being migrated from a second site to the first site. The first network device receives a packet from a second workload for the first workload and determines that a destination of the packet matches the specific route in the routing table. The method routes the packet from the second workload to the first workload using the specific route in the routing table without sending the packet to the second site.

Abstract: In some embodiments, a method determines when a packet is fragmented into multiple fragmented packets in a flow between a first workload and a second workload. The method switches from generating an outer source port in the outer header using layer 4 information from the inner header to using layer 3 information from the inner header. A fragmented packet is encapsulated with the outer header that includes an outer source port value that is generated using the layer 3 information. The method initiates a process to determine when to switch back to using layer 4 information from the inner header to generate the outer source port. When it is determined to switch back to using layer 4 information, the method switches back to using layer 4 information from the inner header to generate the source port in the outer header of a packet from the first workload.

Abstract: In an embodiment, a computer-implemented method for providing dynamic mechanisms for resource-path-based, dynamic group membership support for local and external membership groups is described. A method comprises: detecting, by a group resolver implemented in a management and control plane, that information about an object stored in the plane was created or updated; determining whether a URI of the object matches a URI regular expression and other conditions specified in membership criteria created for a membership group; in response to determining that a URI of the object matches a URI regular expression and other conditions specified in membership criteria created for a membership group: distributing the information about the object to network agents implemented in transport nodes to cause the network agents to automatically update a group membership policy associated with the membership group; and wherein the group membership policy affects packet forwarding behavior of a forwarding node.
