The next in the SCALABLE Network Simulation blog series has launched, continuing the important discussion around predictable communications, this time with respect to support required for diverse application traffic. Written by Dr. Rajive Bagrodia, founder and CEO of SCALABLE Network Technologies (SCALABLE), this piece brings forward Bagrodia’s thought leadership in the field of modeling and simulation, test and analysis, and assessment of the resiliency and impact of cyber threats on large scale networks.
In this latest blog, Bagrodia discusses how heterogeneity, scalability, and simultaneous support for diverse application traffic are hallmarks of contemporary computer and communication networks. Bagrodia further discusses why communication quality is hard to predict for such networks.
By using the example of Voice-over-IP (VOIP), Bagrodio illustrates how competing requirements may interfere with estimating VOIP quality as other factors that are integral to contemporary networks are added to the mix. Some of the challenges that Bagrodia discusses in the blog are:
- Competing traffic (email, web, etc.)
- Diverse networks
- Changing conditions
- Interfering signals
Application heterogeneity, network and/or traffic scalability and wireless signal propagation all impact the end-to-end performance of the network and hence the quality of service it provides for the different services that it provisions. Network simulations that accurately capture such network dynamics can be a powerful tool towards meeting the objective of predictable communications for critical military and enterprise applications. High-fidelity network simulations are critical to accurately capture the impact of realistic operating conditions on network and application performance.
