1. A computer-implemented method comprising:
determining a connection map for a software-defined network, including a plurality of receivers and a plurality of multicast replicators, wherein the connection map is based on one or more policies;
determining, based on the connection map, a first connection path through one or more of the plurality of multicast replicators to a first receiver of the plurality of receivers;
forwarding a packet to the first receiver through the one or more of the plurality of multicast replicators based at least in part on the connection map;
receiving information about one or more of the plurality of multicast replicators, wherein the information includes at least performance of the one or more of the plurality of multicast replicators operating to provide network service access through the software-defined network; and
switching to a second connection path with a different one or more multicast replicators of the plurality of multicast replicators to the first receiver based on the received information.
