Load Balancing
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 33.
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.
