Chapter 1: Introduction
Welcome
Network Optimizer for Gaming and VoIP
Chapter 1: Introduction
Welcome
Thank you for choosing the Network Optimizer for Gaming and VoIP. The Network Optimizer streamlines your
home network for next-generation Internet applications. By applying various Quality of Service (QoS) techniques
to your network traffic, the Network Optimizer makes sure time-sensitive applications like online gaming and
VoIP calls run smoothly.
The Network Optimizer sits between your home router and broadband cable or DSL modem, and monitors the
data going through. It automatically determines what data is time-sensitive and what isn't, and prioritizes
delivery of that data to its destination, ensuring the best-possible performance for the various types of data that
go through your network.
Traffic prioritization helps make sure that your online games don't lag when someone else on the network is
surfing the web or sending email. Voice over IP phone calls sound cleaner. Outgoing streamed video from your
Internet Video Camera runs smoother.
And the best part is that the Network Optimizer takes care of prioritizing the data automatically, with no user
setup of QoS policies required. After a simple installation it gets right to work, enhancing your network's
performance and helping you get the most out of your high-speed Internet connection.
