Not too long ago, network traffic was almost entirely comprised ofvoice or Henry J. Kafka voice-grade traffic. Today, networks must support a rapidly growing percentage ofseveral different kinds ofhigh-bandwidth or broadband trafficdata, image, and video-in addition toconventional voice traffic. There are several factors thatcreate the demand for these new capabilities. Telecommunication customers want faster performance, better quality, customization, lower costs, and anever increasing variety ofadvanced information services. Fornetwork-service providers, increasing competition requires an accentuated focus onproviding timely, reliable, flexible, and evolvable information-network services. But, while network-service providers require new networking technologies to enable the deployment ofadvanced services, they must also increase network efficiencies to maintain control of their operating expenses. How might asynchronous transfer mode (ATM) technology be used to address these needs? This paper discusses some of the expected broadband applications and services enabled with ATM technology, as well as applications and services involving more than a I-Mbit/s peak transport capability. In addition, the prospects for broadband services and applications deployment are also presented.
Today's businesses require the movement and management of an increasing quantity and variety of infomtion. This infomtion explosion will shape the evolution of communications networks and services in ways which we cannot fully comprehend. Network equipment suppliers and service providers are challenged to develop and deploy neworks which cost effectively meet the current needs of their customers, while simultaneously evolving to address their future needs. AT&T Network Systems has deJned a Broadband Networking Architecture which enables network service providers to meet the challenges in today's environment while providing a Pexible pamework for meeting tomorrow's network requirements. This paper bri@y reviews the current BroadbandATM market situation and describes AT&T Network Systems Service Net-2OOO Broadband NetworkArchifecfure plans.
