A new generation of networking requirements is fueling the growth of a
cell-based communications technology known as the asynchronous transf
er mode (ATM). ATM technology allows the integration of voice, video,
traditional data, and other traffic types on a single network. ATM off
ers a unique opportunity to deploy the same standardized networking te
chnology in both the wide-area and local-area environments. IBM has in
troduced a family of products that provides a complete ATM solution fo
r customers. The products support ATM standards, allowing the products
to interwork with devices from other vendors. This paper provides a t
utorial on ATM technology and an overview of the IBM ATM product famil
y. The IBM 8260 Intelligent Switching Hub is described as a representa
tive ATM product.
