Abstract

This article design PON with working vacation mechanism about bandwidth distribution in uplink direction, and optimize the serving rate of vacation and roving by ant colony algorithms (ACA), giving the objective function. The convergence speed can be improved by setting the threshold of objectives. More and more ants concentrate towards the optimal solution space in the result of the change of hormones with the objective function about the cost of system, and the optimal solution is found. The numerical experiments show that this method can allocate rational severing rate for every ONU with high speed of convergence.
