Table 1-9 Considerations for Increasing Network Performance
Network Demands Suggested Design Methods
• Toomanyusersonasingle
network segment and a growing
number of users accessing the
Internet
• Create smaller network segments so that fewer users share
the bandwidth, and place the network resources in the same
logical network as the users who access those resources
most.
• Use full-duplex operation between the switch and its
connected workstations.
• The increased power of new PCs,
workstations, and servers
• High demand from networked
applications (such as e-mail with
large attached files) and from
bandwidth-intensiveapplications
(such as multimedia)
• Connect global resources—such as servers and routers to
which network users require equal access—directly to the
Fast Ethernet or Gigabit Ethernet switch ports so that they
have their own Fast Ethernet or Gigabit Ethernet segment.
• Use the Fast EtherChannel or Gigabit EtherChannel feature
between the switch and its connected servers and routers.
• An evolving demand for IP
telephony
• Use quality of service (QoS) to prioritize applications such
as IP telephony during congestion and to help control both
delay and jitter within the network. Use switches that
support at least two queues per port to prioritize voice and
data traffic as either high or low priority based on
802.1p/Q.
