Abstract:
The disclosure provides an approach for reducing multicast traffic within a network by optimizing placement of virtual machines within subnets and within hosts, and by optimizing mapping of overlay multicast groups to underlay multicast groups. In one embodiment, substantially all VMs of a multicast group are migrated to the same subnet of the network. Thereafter or independently, VMs in the same subnet are migrated to the same host, ideally to the subnet proxy endpoint of that subnet. In the same or in another embodiment, if multiple overlay groups map to the same underlay group, one or more of the overlay groups may be remapped to a separate underlay group to improve network performance.

Claim (Index 18):
A non-transitory computer readable medium comprising instructions to be executed in a processor of a computer system, the computer system comprising a plurality of host machines and a plurality of virtual machines (VMs) running on the plurality of host machines, and the instructions when executed in the processor cause the network to carry out a method of reducing congestion within a network, said method comprising:\n for a first overlay multicast group comprising a first set of VMs of the plurality of VMs, determining at least one of:\n if the first set of VMs spans a plurality of subnets including a first subnet and a second subnet; or \n if the first set of VMs run on multiple host machines of the plurality of host machines including a first host machine and a second host machine, wherein the multiple host machines are in a same subnet; \n when it is determined that the first set of VMs spans the plurality of subnets, migrating at least one VM of the first set of VMs from the first subnet to the second subnet, such that the first subnet no includes any of the first set of VMs; and when it is determined that the first set of VMs run on the multiple host machines, migrating at least one VM of the first set of VMs from the first host machine to the second host machine, such that the first host machine no longer hosts any of the first set of VMs.
