Abstract: An example method of mitigating oversubscription of traffic to edge services gateways in a data center includes: receiving, by a host of the data center, traffic metrics corresponding to the ESGs; determining traffic congestion at a first active edge of the ESGs in response to the traffic metrics; dividing, in response to the traffic congestion, a classless inter-domain routing (CIDR) block assigned to the first active edge into a first CIDR block and a second CIDR block; and creating, in a routing table of a router, a first route between an internet protocol (IP) address of the first active edge and the first CIDR block, and a second route between an IP address of a second active edge of the ESGs and the second CIDR block.

Abstract: The disclosure provides an approach for overcoming the limitations of a cloud provider network when a data center with software-defined network and multiple hosts, each with multiple virtual machines, operates on the cloud provider network. Single-host aware routers and a multiple-host aware distributed router are combined into a hybrid router in each host. The hybrid router receives a route table from the control plane of the data center and updates the received table based on the locations of VMs, such as edge VMs and management VAs on each of the hosts. An agent in each host also updates a router in the cloud provider network based on the locations of the virtual machines on the hosts. Thus, the hybrid routers maintain local routing information and global routing information for the virtual machines on the hosts in the data center.

Abstract: In some embodiments, a method detects a state of a first session between a first workload and a second workload. The first workload and the second workload send packets in the first session via a first path to maintain a state of the first session. When the state of the first session indicates the first workload is down, the method receives information for network metrics of network traffic being sent in the first path. The method determines when the second workload should transition from a standby mode to an active mode to take over as an active workload in an active/standby configuration between the first workload and the second workload based on the information for the network metrics.

Abstract: In some embodiments, a method receives a control message from a second host. The control message includes a first address to use as a next hop to reach an active workload that has migrated to the second host from another host. The method reprograms a local route table to include a policy to send packets to check a liveness of the active workload with the next hop of the first address. A packet is sent from a standby workload to the active workload using the next hop of the first address to check the liveness of the active workload. The packet is encapsulated and sent between the first host and the second host using an overlay channel between a first endpoint of the overlay channel on the first host and a second endpoint of the channel on the second host.
