FEATURE
Understanding the Mechanism of Tools and Practicing Their Use
Techniques for
increasing the speed of network access
- There are tools that enable users to speed up access to a network
just by clicking the appropriate buttons. How can users increase
the speed without upgrading access lines and PCs? Do these tools
really make a difference?
This article examines their mechanism
and presents techniques for enhancing the speed of access to the network.
Part 1: IP – The maximum size not subject to division, which is called
the “MTU size,” allows for the greatest speed
Part 2: TCP – The
default value of Windows should be set to a relatively small number, and the
amount of received buffer space should be increased
Part 3: Application – The
speed is increased by loading web pages before users access them and reducing
the display time

system of the services. This article examines the network topology
and hardware that supports the infrastructure of the major FTTH operators
and reveals every aspect of the Giga FTTH technology.
Prologue: Giga bps fiber optic lines will dominate the market of information
services
Part 1: Network – Examination of the infrastructure of
the four leading operators
Part 2: Hardware – Analyzing the mechanism of
Giga FTTH by studying fiber optics and ONU/OLT
