document: A heuristic approach to resource locations in broadband networks In broadband networks , such as ATM , the importance of dynamic migration of data resources is increasing because of its potential to improve performance especially for transaction processing . In environments with migratory data resources , it is necessary to have mechanisms to manage the locations of each data resource . In this paper , we present an algorithm that makes use of system state information and heuristics to manage locations of data resources in a distributed network . In the proposed algorithm , each site maintains information about state of other sites with respect to each data resource of the system and uses it to find : -LRB- 1 -RRB- a subset of sites likely to have the requested data resource ; and -LRB- 2 -RRB- the site where the data resource is to be migrated from the current site . The proposed algorithm enhances its effectiveness by continuously updating system state information stored at each site . It focuses on reducing the overall average time delay needed by the transaction requests to locate and access the migratory data resources . We evaluated the performance of the proposed algorithm and also compared it with one of the existing location management algorithms , by simulation studies under several system parameters such as the frequency of requests generation , frequency of data resource migrations , network topology and scale of network . The experimental results show the effectiveness of the proposed algorithm in all cases
