High performance distributed computing in FDDI networks

Distributed computing requirements are discussed, and distributed computing in FDDI (fiber distributed data interface) networks is considered. Three applications with different requirements are examined to show how the basic FDDI topology (a dual ring of trees) and mix of station types can he matched to the throughput and reliability requirements of particular applications. These applications are: an engineering graphics application, characterized by high throughput requirements, small workgroups, low-to-medium network reliability requirements, and high-end workstations and graphics servers: an office application, characterized by reasonable response time requirements, connectivity requirements (to corporate networks, both local and wide area), high network reliability requirements, and many PCs and low-end workstations and servers (e.g., print and file); and a military application, characterized by high throughput requirements, low response time requirements, very high network reliability requirements, and a mix of high-end and low-end workstations and servers. FDDI and distributed computing performance considerations are addressed. Tools to support FDDI applications are discussed.<>
