Dynamic connection rearrangements in ATM switching networks

Two classes of ATM (asynchronous transfer mode) switching network architectures based on preset path routing and on statistical self-routing switching techniques are considered. They are evaluated in terms of their basic properties and their capabilities to cope with point-to-multipoint connection requirements. The principles of connection rearrangement techniques in an ATM environment are described and possible applications in both classes of switching network architectures are evaluated. A preset path routing switch can gain considerably in performance for all types of connections at the expense of excessive control effort. A statistical self-routing switch can have advantages for point-to-multipoint connections with moderate additional effort.<<ETX>>
