Center node: "the osu scheme for congestion avoidance in atm networks using explicit rate indication"
  Abstract: An explicit rate indication scheme for congestion avoidance in computer and telecommunication networks is proposed. The sources monitor their load and provide the information periodically to the switches. The switches, in turn, compute the load level and ask the sources to adjust their rates up or down. The scheme achieves high link utilization, fair allocation of rates among contending sources and provides quick convergence. A backward congestion notification option is also provided. The conditions under which this option is useful are indicated.
