Introduction 11
The NSE forwards any and all packets (except those addressed to the NSE network interface).
The packets are unmodified and can be forwarded in both directions. The Bridge Mode
function is a very useful feature when troubleshooting your entire network as it allows
administrators to effectively “remove” your product from the network without physically
disconnecting the unit.
Class-Based Queueing
The Nomadix Class-Based Queueing feature provides the ability to define multiple groups
(classes) of users. You can prioritized groups and guarantee minimum bandwidth on a per-
group basis.
Users are added to classes, and rules are applied across the entire class. Each class has three
configurable attributes:

Priority

Minimum Bandwidth

Maximum Bandwidth
Class-based queueing does not apply rules to individual users. You may use bandwidth limits
to restrict individual users, if desired.
Class-based queueing does not provide application-level (layer 7) throttling or class of service.
Rules are applied when there is contention for bandwidth (i.e. when link is saturated).
Use Case: Property has 100 Mbps WAN Link
In this scenario, a property wishes to provide guaranteed minimum bandwidth and prioritize
traffic across three groups: Conference, Guest Room, Public Areas. The property can configure
class-based queuing according to the following table.
** Note that ‘User Bandwidth Limit is not an attribute of Class Based Queueing, but can be
applied (if desired) using existing Bandwidth Limit functionality.
Class Priority Minimum Maximum
User Bandwidth

Conference 1 30 Mbps 100 Mbps 5 Mbps
Guest Room 2 50 Mbps 100 Mbps 5 Mbps
Public 3 20 Mbps 100 Mbps 3 Mbps
