Optional NSE Modules
Load Balancing
Load Balancing requires an optional NSE product license.
With the Load Balancing Module, Internet traffic is balanced across multiple WAN/ISP connections to ensure
that traffic is distributed based on the capability of each connection. For example, organizations may wish to
balance traffic between a low-cost DSL WAN/ISP and one high-performance, high-capacity WAN/ISP. This
is of value when multiple links are used to optimize cost for Internet service, such as balancing traffic between
one low-cost DSL WAN/ ISP and one high-performance, high-capacity WAN/ISP. Hotels may also use this
capability to provide tiered services reflecting the capacity of the WAN/ISP connection.
The Link Failover feature of the Load Balancing Module is designed to improve business continuity. In the
event that one or more links fail, traffic is seamlessly rerouted to the remaining surviving links without lapse
of service. When the failed links recover, the NSE routes new connections toward the now-working links until
a normal, balanced configuration is reached.
For details of the Load Balancing capabilities and sample use cases, see Load Balancing and Link Failover
on page 27.
Hospitality Module
The optional Hospitality Module provides the widest range of Property Management System (PMS) interfaces
to enable in-room guest billing for High Speed Internet Access (HSIA) service. This module also includes 2-
Way PMS interface capability for in-room billing in a Wi- Fi enabled network. In addition, the Hospitality
Module includes the Bill Mirror functionality for posting of billing records to multiple sources. With this
module, the NSE also supports billing over a TCP/IP connection to select PMS interfaces.
By integrating with a hotel’s PMS, your NSE-powered product can post charges for Internet access directly to
a guest’s hotel bill. In this case, the guest is billed only once. The NSE outputs a call accounting record to the
PMS system whenever a subscriber purchases Internet service and decides to post the charges to their room.
Nomadix’ Access Gateways are equipped with a serial PMS interface port to facilitate connectivity with a
customer’s Property Management System.
Some Property Management Systems may require you to obtain a license before
integrating the PMS with the Access Gateway. Check with the PMS vendor.
High Availability Module
Your product license may not support this feature.
The optional High Availability Module offers enhanced network uptime and service availability when
delivering high-quality Wi-Fi service by providing Fail-Over functionality. This module allows a secondary
Nomadix Access Gateway to be placed in the network that can take over if the primary device fails, ensuring
Wi-Fi service remains uninterrupted.
