Virtual Network Master

Communication quality measurement in cloud/virtual environments

With the growth of Cloud computing and virtualization, communication quality between applications is significantly affected by the virtual layer, making measurement that includes virtual environments increasingly important. The Virtual Network Master solution measures communications quality and is compatible with Cloud/virtual environments. This introduces its features.

Accurately measure communication quality, including Cloud/virtual environments
Since it is difficult to install physical measuring devices in cloud/virtual environments, it is challenging to determine the communication quality between applications in virtual environments with the same high precision as measurements using physical measuring devices.
The Virtual Network Master converts the functions of physical test devices into software and operates on Cloud platforms, making it possible to set measurement points on communication paths within virtual environments.

Generating stable traffic and achieving high-precision latency measurement support accurate evaluation of end-to-end communication quality including Cloud/virtual environments.

Accurate measurement tailored to applications
The Virtual Network Master evaluates communication quality including virtual environments by active testing using similar traffic to applications in virtual environments. Applications such as video transmission where traffic load differs between uplink and downlink require measurement with different parameters in each direction. The Virtual Network Master measures latency and frame loss individually for uplink/downlink, offering detailed quality evaluation that matches actual application behavior.
One-way latency measurement by synchronizing time using NTP

One-way latency measurement is possible by synchronizing time with an NTP server and adding time information to all measurement frames.

Recording the latency time of each frame and aggregating maximum, minimum, and average values at one-second intervals visualizes network latency fluctuations accurately and even instantaneous latency peaks can be captured with high precision.
Active testing with line load and frame size tailored to applications

UDP packets are generated with individually specified line load and frame size for uplink/downlink for individual measurement of asymmetric uplink/downlink traffic.

Facilitates stable traffic generation/measurement compared to open-source tools
Open-source network performance measurement tools are used commonly for general communication-quality evaluation, but the Virtual Network Master supports one-way latency measurement and allocates dedicated cores for transmission and reception, supporting stable traffic generation and measurement without effects from other applications.
The quality of communications including virtual environments is evaluated accurately by using active testing with similar traffic to applications in virtual environments.
