Chapter 13 Bandwidth Management; Bandwidth Management Overview; Bandwidth Allocation; Activating Bandwidth Management - ZyXEL Communications VSG-1200 User Manual

This chapter describes the bandwidth feature and shows you how to configure bandwidth control.

13.1 Bandwidth Management Overview

Bandwidth management allows you to control the amount of outbound and inbound traffic on the LAN. This helps
reduce delays and dropped packets due to busy network traffic. On the VSG, outbound traffic refers to network
traffic coming from a LAN port to the WAN port whereas inbound traffic refers to network traffic coming from the
WAN port to a LAN port.
13.1.1

Bandwidth Allocation

The VSG provides two types of bandwidth control based on a subscriber's computer MAC address: equal share or
class-based.
With equal share bandwidth allocation, you set the VSG to allocate an equal amount of outgoing and incoming
bandwidth for each subscriber on the LAN.
With class-based bandwidth allocation, you can set up classes of different bandwidth capacity. You can configure
bandwidth classes on a RADIUS server or in the billing profiles.
