Multimedia network alternatives for LANs

摘要

The three LAN architectures discussed have distinct advantages and disadvantages for multimedia traffic. Heterogeneous IsoEthernet LANs and homogeneous ATM LANs can both support seamless internetworking for multimedia traffic. ATM networks dynamically access the entire channel bandwidth and are easily scalable. Isochronous C-channel TDMA LANs for voice and compressed video are less complex, are not subject to switch congestion loss and can be introduced incrementally into existing packet LANs.
