In broadband networks such as ArM (Asynchronous Transfer Mode) networks, the dynamic migration of data resources, such as databases and files, has become more powerful and effective than that in conventional networks so far.In environments with migratory data resources, it is necessary to develop a method to manage the location of each resource.In this paper, we discuss the location management of migratory data resources.First, we propose several resource location management methods: some of them are based on conventional methods, and the rest are new methods which make use of the features of ATM networks.Then, we compare the performance of the methods by simulation studies under several system parameters, such as the frequency of accesses and resource migrations, and the scale of the network.Based on the comparisons, we show the optimal location management method for a given system environment.
