38 * Available ressource assignment modes
45 * Assign each peer an equal amount of bandwidth (bw)
47 * bw_per_peer = bw_total / #active addresses
54 * Solve ressource assignment as an optimization problem
55 * Uses an mixed integer programming solver
60 * Reinforcement Learning mode:
62 * Solve resource assignment using a learning agent
69 * Initialize address subsystem. The addresses subsystem manages the addresses
70 * known and current performance information. It has a solver component
71 * responsible for the resource allocation. It tells the solver about changes
72 * and receives updates when the solver changes the ressource allocation.
