The evolution from LAN/MAN to broadband ISDN
Wolfgang M. Fischer, E.-H. Goeldner, N. C. Huang · 2002
The evolutionary path for the interconnection of data communication systems (based on LANs) first via MANs (metropolitan area networks) and later on (as soon as available) via the BISDN (broadband ISDN) is presented. As the BISDN aims at the integration of a connectionless service with connection-oriented services, a smooth evolution can be expected. MANs emerge for these services to become a part of the BISDN, maintaining the already installed equipment.>
