Optimizing Performance 6-1

Optimizing Performance
Introduction
The performance of your LAN is usually determined by a complex combination
of different factors. This section will present a number of considerations that
may help you to:
■
Determine whether optimization is really needed,
■
Tailor your 11Mbps Wireless LAN network to optimize its performance.
Consider optimizing network performance in these situations:
■
You are troubleshooting a suspected problem
■
LAN performance is less then expected, or
■
Routine checks at regular intervals show a performance degradation.
In this chapter, we recommend various solutions to some of the most commonly
reported problems. The benefit of each of the proposed solutions will largely
depend on the actual situation that caused the current performance.
CAUTION:Create separate backup files of the configuration data for each
Access Point, before you start changing the configuration(s). Doing
so will enable you to restore the initial setup of your network in
case corrective actions did not result in the desired effect.
Eliminating Redundant Traffic
Data transmitted via your network can be divided in two major types of data:
■
True Data - is data communicated between network stations, such as file-
transfer or e-mail. This “True Data”, usually referred to as “payload”, also
includes messages that were retransmitted one or multiple times as a result
of a collision, malfunctioning cable connection or poor radio link.
In the AP Manager Remote tab in the monitoring mode, the “True Data” is
displayed as Unicast Packets.
■
Network Overhead Data - is data exchanged between network services to
control the dataflow. This overhead data that usually referred to as “traffic
load”, includes protocol and broadcast messages and/or error messages that
result from a configuration mismatch.
In the 11Mbps Wireless LAN A PManager Remote tab in the monitoring
mode, the “Network Overhead Data” is displayed as Non-Unicast Packets.
