This paper focuses on the relative merits of various LAN technologies. This paper demonstrates a migration path for existing, shared Ethernet LANs. It discusses where it makes economical sense to use an Ethernet switch and FDX links to alleviate performance bottlenecks in the network. It also shows how these LANs can be linked together with fast Ethernet LANs, ATM LANs, and ATM backbones. In this paper, we compare shared and switched LANs in terms of topology and performance characteristics.
Factors considered include network topology, performance improvements, and migration impact.
Finally, the role of emerging high-speed networks such as ATM is discussed in the switched environment, both as a campus backbone and as a desktop connection. This paper describes the 3746 Nways Multinetwork Controller and shows how APPN can provide you with powerful networking solutions in terms of functions, connectivity, performance, availability, growth enablement and evolution, system management, cost savings.
