Abstract	We propose and implement an enhanced moving average (MA) based dynamic resource allocation method for optical packet and circuit integrated (OPCI) networks. In the OPCI networks, optical packet switching (OPS) and optical circuit switching (OCS) share the total bandwidth in a fiber by allocating separate wavelength resources to them. In this work, we leverage an exponential moving average (EMA) as an enhanced MA. Every time a signaling process for path establishment or release occurs at a node, the proposed method employs the EMA of number of in-use paths to reallocate wavelengths to OCS and OPS while the conventional method employs the absolute number of in-use paths. When the EMA reaches or becomes less than a threshold value, the dynamic resource allocation is executed. As results of simulations and a verification experiment, we show that the proposed method can reduce the amount of routing processes without suffering from blocking of path establishments in comparison to the conventional method. In addition, it is expected that the proposed method can effectively allocate vaster amount of bandwidth to OPS without suffering from the blocking and achieve better system performances for OPS.
