Data centers avoid IP Multicast because of a series of problems with the technology. We propose Dr. Multicast (MCMD), a system that maps IPMC operations to a combination of point-to-point unicast and traditional IPMC transmissions. MCMD optimizes the use of IPMC addresses within a data center, while simultaneously respecting an administrator-specified acceptable-use policy. We argue that with the resulting range of options, IPMC no longer represents a threat and can therefore be used much more widely.
