Abstract: The disclosure provides an approach for reducing congestion within a network, the network comprising a plurality of subnets, the plurality of subnets comprising a plurality of host machines and a plurality of virtual computing instances (VCIs) running on the plurality of host machines. Embodiments include receiving, by an edge services gateway (ESG) of a first subnet of the plurality of subnets, membership information for a group identifying a subset of the plurality of host machines. Embodiments include receiving a multicast packet directed to the group and selecting from the plurality of host machines, a replicator host machine for the multicast packet. Embodiments include sending, to the replicator host machine, the multicast packet along with metadata indicating that the replicator host machine is to replicate the multicast packet to remaining host machines of the subset of the plurality of host machines identified in the membership information for the group.

Abstract: A method of transmitting multicast traffic to workloads of tenants communicating over overlay networks provisioned on top of a physical network includes the steps of: detecting the multicast traffic; determining that the multicast traffic is bound for workloads of a first tenant and workloads of a second tenant; encapsulating one instance of the multicast traffic using a Layer 2 (L2) over Layer 3 (L3) encapsulation protocol to generate encapsulated traffic, wherein the encapsulated traffic includes an identifier of a first backplane network corresponding to the first tenant and an identifier of a second backplane network corresponding to the second tenant in a header portion of each packet of the encapsulated traffic; and transmitting, to a first host computing device, the encapsulated traffic with the identifiers of the first and second overlay networks.

Abstract: Certain embodiments described herein are generally directed to a method for managing packets at a virtual forwarding element of a hypervisor. In one example, the method includes receiving a first plurality of packets at a virtual port of the virtual forwarding element. The method further includes detecting the first plurality of packets correspond to a signature configured at the virtual port. The method also includes dropping at least one packet of the first plurality of packets at the virtual port based on detecting the first plurality corresponds to the signature. The method further includes receiving a second plurality of packets at the virtual port of the virtual forwarding element, wherein the second plurality of packets do not correspond to the signature. The method also includes forwarding the second plurality of packets to one or more destinations by the virtual forwarding element.

Abstract: Example methods are provided for a host to perform queue filter configuration for multicast packet handling in a software-defined networking (SDN) environment. One example method may comprise the host generating and sending a request to join an outer multicast group address to one or more multicast-enabled network devices; and configuring a queue filter based on the outer multicast group address. In response to detecting an ingress encapsulated multicast packet that includes an outer header addressed to the outer multicast group address, the host may assign the ingress encapsulated multicast packet to a particular NIC queue from the multiple NIC queues based on the queue filter; and retrieving, from the particular NIC queue, the ingress encapsulated multicast packet to generate and send a decapsulated multicast packet to a virtualized computing instance.
