Abstract: Exemplary methods, apparatuses, and systems configure a first set of ports of a host device to be included within a link aggregation group (LAG) with a switch coupled to the first set of one or more ports. A second set of one or more ports of a second host device is also included within the LAG. The configuration of the LAG includes the switch performing load balancing between ports within the LAG. The first host device receives, via the LAG, a packet to be processed by a service implemented by each of one or more virtual machines running on the first host device. The first host device receives the packet as a result of the switch selecting a port within the first and second sets of ports based upon the load balancing between uplinks to the ports within the LAG.

Abstract: Exemplary methods, apparatuses, and systems include a first host device determining that a first packet from a first virtual machine (VM) within the first host device is to be transmitted to a second VM on a second host device and that the first host device and the second host device each transmit or receive packets via ports within a first link aggregation group (LAG). In response to determining that the first host device and the second host device each transmit or receive packets via ports within the first LAG, the first host device transmits the first packet from a first synchronization port of the first host device to a second synchronization port of the second host device. The first and second synchronization ports are excluded from sharing a common LAG with any ports of another host device.

Abstract: Exemplary methods, apparatuses, and systems include virtualization software of a host computer receiving a first packet addressed to a first virtual link layer address. Each of a first plurality of virtual machines on the first host computer is configured to share the first virtual link layer address. The virtualization software of the first host computer maps a flow of packets, including the first packet, to a first virtual machine within the first plurality of virtual machines and forwards the first packet to the first virtual machine. The virtualization software of the first host computer receives a second packet from the first virtual machine in response to the first packet. The second packet includes the first virtual link layer address as a source address for the first virtual machine.

Abstract: Exemplary methods, apparatuses, and systems configure a first set of ports of a first host device and a second set of ports to be included within a first link aggregation group (LAG). The first and second host devices further configure, respectively, a first synchronization port that does not share a common LAG with the second host device and a second synchronization port that does not share a common LAG with the first host device. The first host device receives a first packet destined for a virtual machine running on the second host device, the first packet including source and destination information. The first host device determines from the source or destination information that the first packet is destined for a virtual machine running on another host device. In response, the first host device forwards the packet via the first synchronization port to the second host device.
