Network Emulation WINNING ON THE WAN:
How to Validate Network Applications Before You Deploy
If you’re like most organizations in today’s network-centric
world, you need to ensure that your applications run properly over private
and public Wide Area Networks (WANs). This is particularly challenging
for those applications that are sensitive to network conditions, such
as real time transactions, enterprise storage, streaming media, IPTV and
VoIP.
The only way to have confidence that a given application (or solution,
or service) will operate with acceptable performance once it is deployed
is to test it under expected - and maybe unexpected - production network
conditions prior to deployment. Conditions such as latency, bandwidth
limitations, bit errors, dropped packets, and packet jitter all impact
application performance. Fortunately, knowing how your application functions
in the presence of these actual and unfavorable conditions is possible
using an emulated network environment.
This type of environment can be created in a lab using a network emulator.
Network emulators are hardware devices that can duplicate network conditions
under user control, allowing you to precisely control the amount of errors,
delay and other impairments that you add to network traffic. With their
ability to vary delay times and emulate Quality of Service (QoS) metrics,
network emulators are superior to the alternative of using spools of fiber
to characterize long-haul network behavior. With their accuracy and ability
to function at full line rate, hardware based network emulators outperform
software simulation tools for validating network applications.
When using a network emulator, however, knowing the appropriate combinations
and variations of delays and impairments to emulate is not easy. This
white paper is a “How to” guide for getting started. The goal
is to equip network managers with the knowledge they need to run their
critical networked applications in an “emulated” environment
in order to establish, maintain and optimize the performance and availability
of these solutions.
