The central-force network dynamics model for glasses is extended to treat networks involving small regular rings of bonds. In particular, band-limit formulas are obtained for an A2X3 glass consisting of regular puckered six-membered A3X3 rings. The special case of planar rings is compared with observations on vitreous B2O3. This continuous random network of "boroxol" rings shows improved agreement with experiment over a model not containing rings. The remaining discrepancies illustrate the need to include noncentral forces in the network dynamics of v-B2O3.
