1. An apparatus, comprising:

  • a processor; and

    a non-transitory computer-readable memory communicatively coupled to the processor, the memory including a set of instructions stored thereon and executable by the processor for;

    constructing a trellis having a number of states at least equal to a number of edge servers to be included in an edge-server set, wherein each state comprises a plurality of nodes, each node corresponding to one of the plurality of candidate edge servers;

    employing a trellis-exploration algorithm to select the edge-server set, comprising providing interconnects between each node of a first state to each of a plurality of nodes in a next state, and for each node in a state, selecting a path corresponding to a best performance metric that connects to a node in a previous state, wherein each performance metric comprises network topology information, the network topology information comprising channel measurements from candidate edge servers; and

    distributing data signals to the edge-server set, the data signals to be transmitted to client devices being served by the edge-server set.
