Even a small, unexpected delay on the network can result in lost revenue and/or dissatisfied customers.
Your system depends on the performance and reliability of the network. Unfortunately, any number of things can interfere with network service levels: Access links introduce crosstalk, RFI, impulse noise and white noise. Packets can be dropped or delayed, duplicated or swapped around. Links go down.
Depending on your system, even a small, unexpected delay on the network can result in lost revenue and/or dissatisfied customers. Problems must be detected and corrected before release or deployment.
What to Test
Networks continue to increase in number of users, bandwidth, services and complexity. A network test bed must realistically reproduce this complexity and scale while testing:
- Quality of experience (QoE)—as represented by transaction response times, throughput, MOS, VMOS, R-Factor, MDI or other relevant metrics in a realistic network environment
- Service availability—under adverse network conditions
- Outage or unfavorable network conditions—and failover to a backup link or system
- Ability to minimize or compensate—for realistic network conditions, such as jitter, latency and loss
- Performance—during normal and disaster conditions
