  • Page 133 Network Configurations that are friendly to Streaming 100BaseT Switched Networks More bandwidth is always better than less bandwidth. 100BaseT appliances have more features and more capabilities than 10BaseT appliances. While it is true that a 10BaseT network can theoretically support the streaming of an MPEG-1 SIF stream at 1-1.2 Mbps, this will effectively use 30% to 40% of available bandwidth, rendering the network ineffective.
  • Page 134 Appendix C • Optimizing your Network (Metropolitan Area Network). LAN Emulation (LANE) is used in these types of networks to give an Ethernet feel to the network. This emulation is easier to implement than IP emulation over ATM and is much more popular. ATM’s broad bandwidth (155Mb) and interfaces, with no collisions, is ideal for streaming.
