Chapter 2: Router Applications
2.1 Overview
Your BiGuard 2/10 Router is a versatile device that can be configured to not only
protect your network from malicious attackers, but also ensure optimal usage of
available bandwidth with Quality of Service (QoS). Alternatively, BiGuard 2/10 can
also be set to handle secure connections with Virtual Private Networking (VPN).
The following chapter describes how BiGuard 2/10 can work for you.
2.2 Bandwidth Management with QoS
Quality of Service (QoS) gives you full control over which types of outgoing data
traffic should be given priority by the router. By doing so, the router can ensure that
latency-sensitive applications like voice, bandwidth-consuming data like gaming
packets, or even mission critical files efficiently move through the router even under
a heavy load. You can throttle the speed at which different types of outgoing data
pass through the router. In addition, you can simply change the priority of different
types of upload data and let the router sort out the actual speeds.
2.2.1 QoS Technology
QoS generally involves the prioritization of network traffic. QoS is comprised of
three major components: Classifier, Meter, and Scheduler. Each of these
components has a distinct role in ensuring that incoming and outgoing data is
managed according to user specifications.
The Classifier analyses incoming packets and marks each one according to
configured parameters. The Meter communicates the drop priority to the Scheduler
and measures the temporal priorities of the output stream against configured
parameters. Finally, the Scheduler schedules each packet for transmission based on
information from both the Classifier and the Meter.
