Abstract: Some embodiments of the invention provide a method of sending data in a network that includes multiple worker nodes, each worker node executing at least one set of containers, a gateway interface, and a virtual local area network (VLAN) tunnel interface. The method configures the gateway interface of each worker node to associate the gateway interface with multiple subnets. Each subnet is associated with a namespace, a first worker node executes a first set of containers of a first namespace, and a second worker node executes a second set of containers of the first namespace and a third set of containers of a second namespace. The method sends data between the first set of containers and the second set of containers through a VLAN tunnel between the first and second worker nodes.

Abstract: Some embodiments provide a method for a first smart NIC of multiple smart NICs of a host computer. Each of the smart NICs executes a smart NIC operating system that performs virtual networking operations for a set of data compute machines executing on the host computer. The method receives a data message sent by one of the data compute machines executing on the host computer. The method performs virtual networking operations on the data message to determine that the data message is to be transmitted from a port of a second smart NIC of the multiple smart NICs. The method passes the data message to the second smart NIC via a private communication channel connecting the plurality of smart NICs.

Abstract: Some embodiments of the invention provide novel methods for providing transparent services for multicast data messages traversing a network edge device operating at a boundary between two networks. The method analyzes data messages received at the network edge device to determine whether they require a service provided at the boundary and whether they are unicast or multicast (including broadcast). The method modifies a multicast destination media access control (MAC) address of a multicast data message requiring a service to be a unicast destination MAC address and provides, without processing by a standard routing function, the modified data message directly to an interface associated with a service node that provides the particular service required by the data message. The method receives the serviced data message, restores the multicast destination MAC address, and forwards the serviced data message to a set of destinations associated with the multicast destination address.

Abstract: Disclosed are aspects of memory-aware placement in systems that include graphics processing units (GPUs) that are virtual GPU (vGPU) enabled. In some examples, graphics processing units (GPU) are identified in a computing environment. Graphics processing requests are received. A graphics processing request includes a GPU memory requirement. The graphics processing requests are processed using a graphics processing request placement model that minimizes a number of utilized GPUs that are utilized to accommodate the requests. Virtual GPUs (vGPUs) are created to accommodate the graphics processing requests according to the graphics processing request placement model. The utilized GPUs divide their GPU memories to provide a subset of the plurality of vGPUs.

Abstract: Example methods and systems for virtual tunnel endpoint (VTEP) mapping for overlay networking are described. One example may involve a computer system monitoring multiple VTEPs that are configured for overlay networking. In response to detecting a state transition associated with a first VTEP from a healthy state to an unhealthy state, the computer system may identify mapping information that associates a virtualized computing instance with the first VTEP in the unhealthy state; and update the mapping information to associate the virtualized computing instance with a second VTEP in the healthy state. In response to detecting an egress packet from the virtualized computing instance to a destination, an encapsulated packet may be generated and sent towards the destination based on the updated mapping information. The encapsulated packet may include the egress packet and an outer header identifying the second VTEP to be a source VTEP.

Abstract: Some embodiments provide a method for forwarding multicast data messages at a forwarding element on a host computer. The method receives a multicast data message from a routing element executing on the host computer along with metadata appended to the multicast data message by the routing element. Based on a destination address of the multicast data message, the method identifies a set of recipient ports for a multicast group with which the multicast data message is associated. For each recipient port, the method uses the metadata appended to the multicast data message by the routing element to determine whether to deliver a copy of the multicast data message to the recipient port.

The load balancer selects, for the data message, a particular destination machine (e.g., a frontend machine for a set of backend servers) in the set of destination machines by performing a load balancing operation based on the received link state data.
