How does packet-based switching affect the quality of service and performance of ATM networks?
Asynchronous transfer mode (ATM) is a network technology that uses fixed-length cells to transmit data, voice, and video over various media. ATM networks are designed to support different types of traffic with different quality of service (QoS) requirements, such as real-time, interactive, and best-effort. However, ATM networks also face challenges from packet-based switching, which is the dominant mode of data communication in the Internet. How does packet-based switching affect the QoS and performance of ATM networks? In this article, we will explore some of the advantages and disadvantages of both approaches, and how they can coexist or interoperate.
