An experimental study of logical office service over international ATM networks

Recently, demand for mobile computing environments has been increasing greatly, and easy access from remote sites has become desirable. To meet this requirement, NTT has proposed a "Logical Office" service, which enables terminal plug & play, multiprotocol, and ubiquitous communication. NTT has already done some Logical Office service experiments, in LAN and Internet environments, which focused on the service offered in the early stages. The paper investigates our proposed Logical Office service over international ATM networks, which focuses on the future stage international ATM test beds between Japan and the US, provided by AT&T, KDD, and NTT, are used for this experiment. It was verified that the Logical Office service worked correctly in the international ATM environments, and that it provided sufficiently practical performance even there.
