Understanding How Applications Perform on the Network — Even Under Adverse Network Conditions — Trial deployments are expensive and yield limited data. Learn how to properly characterize your application or device performance prior to deployment.
Are you allocating your test resources correctly? — Finding and fixing software defects constitutes the largest expense for the software industry. See why line speed testing isn’t enough and the importance of functional testing!
Emulating Mobile/Cellular Networks — Today, more than ever, applications need to be prepared to run over mobile infrastructure. Learn about the characteristics that impact application performance and recommended testing.
Network Protocol Testing Overview — Learn about the categories of network testing and determine how to apply the right ones to your testing effort.
DARPA Robotics Finals: Degrading the Network — Can robots perform "first responder" activities? Can they operate semi-independently or are they merely marionettes? DARPA pushed robot technologists to transfer more intelligence to the robots to carry out simple tasks.
Degraded Networks at the DARPA Robotics Challenge — Learn how the network was simulated to approximate a real life disaster situation for the robots at the DARPA Robotics Challenge
Does IPERF Tell White Lies? — Does Iperf significantly under report the actual bandwidth of the link?
Rate Limitation vs. Bandwidth Limitation — Not the same thing! Reduced bandwidth link emulation is a technique used in a lab to evaluate how a network application behaves when its packets traverse a slow link.
Network Emulation FAQ — Understanding modelers, emulators, and simulators. Choose the right one for your task.
Causes and Correlation of Network Impairments — Learn how ARP cache timeouts and leaky VLANS (among other things) create delay, loss, jitter, and more to packets as they traverse the network.
Instance IDs in SNMP — Understanding scalar and columnar objects and the concept of multiple instances of one object.
Limitations of ICMP Echo for network measurement — ICMP Echo, more commonly known as "ping" is not a valid tool for measuring network distance or performance.
End-to-End VoIP Product Comparison Testing — More than vendors want to admit, the voice quality of VoIP calls depends on the software in the receiving phone.
