Network coding in cyclic networks meets more problems than in acyclic networks. Recently, S.-Y.R.Li et al.proposed a framework of convolutional network coding (CNC) as well as its four properties for cyclic networks with theoretic fundamentals of discrete valuation ring (DVR). The four properties, convolutional multicast (CM), convolutional broadcast (CB), convolutional dispersion (CD) and basic convolutional...
