Introduction
Networks need to be tested to ensure they perform properly.
Local Area Network (LAN) testbeds play an important role in analyzing networks' behaviour.
Network monitoring can help manage the network performance.
We use ATM testbed to measure and evaluate the performance of multicasting and point-to-point multimedia transmissions in IP over ATM networks.
Videoconferencing, corporate communications, and distance learning applications use multicasting to send data packets across the Internet.
