Using Bandwidth Management on the NBG-418N v2

Bandwidth management provides a convenient way to manage the use of various services on the

network. It manages general protocols (for example, HTTP and FTP) and applies traffic prioritization

to enhance the performance of delay-sensitive applications like voice and video.

In the figure below, uplink traffic goes from the LAN device (

A

) to the WAN device (

B

). Bandwidth

management is applied before sending the packets out to the WAN. Downlink traffic comes back

from the WAN device (

B

) to the LAN device (

A

). Bandwidth management is applied before sending

the traffic out to LAN.

Bandwidth Management Example

You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual

applications (like VoIP, Web, FTP, and E-mail for example).

This example shows you how to configure the Bandwidth Management with the following

parameters on your NBG-418N v2 (in router mode).

Overview

This chapter discusses how to configure the wireless network settings in your NBG-418N v2. See

the appendices for more detailed information about wireless networks.

The following figure provides an example of a wireless network.

Figure 41

Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices

A

and

B

are

called wireless clients. The wireless clients use the access point (

AP

) to interact with other devices

(such as the printer) or with the Internet. Your NBG-418N v2 is the AP in the above example.
