5-24 Fine-Tuning Your Network

Wired Ethernet
As gigabit-speed Ethernet ports (10/100/1000 Mbps) become common on newer computers,
wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can
extend up to 100 meters with twisted-pair wiring of CAT-5e or better. A wired connection is
not susceptible to interference, and eavesdropping would require a physical connection to
your network.
Assessing Your Speed Requirements
Because your Internet connection is likely to operate at a much lower speed than your local
network, faster local networking technologies may not improve your Internet experience.
However, many emerging home applications require high data rates. For example:
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. Table 5-2 shows the time to transfer one gigabyte (1 GB) of data
using various networking technologies.
Note: Actual data throughput will vary. Network conditions and environmental factors,
including volume of network traffic, building materials and construction, and
network overhead, can lower actual data throughput rate.
