9. Fighting a Slow Network

Chapter 9. Fighting a Slow Network

image with no caption

As a network administrator, much of your time will be spent fixing computers and services that are running slower than they should be. But just because someone says that the network is running slowly does not mean that the network is to blame.

Before you begin to tackle a slow network problem, you first need to determine whether the network is in fact running slowly. You’ll learn how to do that in this chapter.

We will begin by discussing the error-recovery and flow-control features of TCP. Then we will explore how to detect the source of slowness on a network. Finally, we will look at approaches for baselining networks and the devices and services that run on them. Once you have completed this chapter, you should be much better equipped to identify, diagnose, and troubleshoot slow networks.
