Overlay-based network virtualization has been getting attention to realize multi-tenant datacenters. But the multi-tenant property makes broadcast/multicast communication on virtual networks difficult. In this paper, we propose a novel broadcasting approach which does not use using IP multicast. OpenFlow-enabled virtual switches are grouped based on network distance and each group elects a representative switch to reduce number of
packets. In our approach, sender-side virtual switches ask network topology information to an OpenFlow controller and make broadcast packets into unicast containing the topology information. Representative switches forward this
packet in their groups. We evaluated the number of broadcast of each link in a datacenter-based topology. The results show that proposed method reduced up to 62% of packets in a upstream link, up to 43% of packets in a sender-side link. |
