• Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss
can disrupt your video, plan to provide at least twice the capacity you need.
• Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most
modern networks. Like video, however, streaming audio is also sensitive to latency and
packet loss, so a congested network or a noisy link can cause problems.
• Backing up computers over the network has become popular due to the availability of
inexpensive mass storage. The following table shows the time to transfer 1 gigabyte (1
GB) of data using various networking technologies.
