This paper proposes local lightwave networks with grouping property which are based on a wavelength division multiplexing (WDM). The proposed network is partitioned into several groups according to traffic volume between stations so that traffic is more likely to be within groups. The stations within a group are connected to a braodcast-and-select WDM network with star topology. For inter-group communication, a WDM network of each group is connected to another star-topology WDM network through a special station called a router. In the proposed network, intra-group communication is achieved by one hop and inter-group communication goes through multiple hops. we analyze the average hop number, the maximum throughput, and the mean packet delay of the proposed network and investigate its performance characteristics. Since the proposed network has the better performance as its grouping property strengthens, it is fit for local lightwave networks with the locality of traffic.
