with the advent of cloud computing

With the advent of cloud computing and the Internet of Things, the importance of pre-

deployment network performance testing cannot be over-emphasized. Will your app

or device perform under all network conditions ranging from the routine to the

extreme?

Some apps and devices will simply not work when certain kinds of network conditions

occur. Voice communications, for example, generally become unintelligible at certain

levels of packet delay that are a common occurrence on today’s Internet!

best practice is to characterize the full

Best practice is to characterize the full performance profile of the app or device. This way

you can avoid inappropriate usage scenarios for your app or device or handle these

scenarios with a message to the user that “the network is currently unreachable”.

First, there’s some basics you should cover when selecting test equipment to characterize

performance:

1 will you use a wan emulator appliance

1. Will you use a WAN emulator appliance or a conventional network emulator? Do you

know what level of accuracy is required for your app or device to function properly? A

WAN emulator appliance (a network emulator application operating in a virtualized

environment) can eliminate installation and configuration issues, but may not offer the

level of accuracy required.

2. How does your app or device respond to packet loss (a frequent occurrence on the

Internet)? Can your emulator act as a packet loss simulator? Or, better yet, the

emulator should go beyond simulation and actually drop packets (and introduce other

common impaired network phenomenon, such as delay, reordering, jitter, etc.) before

the packets reach your device or app. so that you can truly understand performance

under various packet loss conditions.

3 another important consideration particularly

3. Another important consideration, particularly in voice and video apps and devices is

delay or latency. Can your emulator serve as a latency generator by stepping through

all the conditions that are likely to occur that delay the delivery of packets on the

Internet?

4. Finally, although it is a little complicated, your emulator should serve as a network

bandwidth simulator. You will need to understand how your app or device performs

when bandwidth is limited. In addition, there’s a difference between rate limitation

and bandwidth limitation.

IWL is the leader in network bandwidth simulator, packet loss simulator and latency

generator, wan emulator appliance tool that enhance the productivity of management

software developers.
