Mobility support in open bridged networks

The proliferation of powerful portable computers and the need for uninterruptible access to information impose new requirements on communication services, particularly regarding the provision of mobility support. The authors focus on mobility in an open bridged networking environment, i.e., bridged LANs interconnected by open bridges (OBs) across a public switched networks (such as SMDS and B-ISDN). A simple timer-based mechanism is applied to the management of location information databases in order to efficiently support mobility within such an environment
