# Invited Talk: Hybrid Network Modeling and Simulation for Scale

## Hybrid Network Modeling and Simulation for Scale (大规模网络混合建模与仿真技术)

2nd Global Future Network Development Summit

Nanjing, China

### Abstract

Modeling and simulation (M&S) plays an important role in the design analysis and performance evaluation of complex systems. Many of these systems, such as computer networks, involve a large number of interrelated components and processes. Complex behaviors emerge as these components and processes inter-operate across multiple scales at various granularities. M&S must be able to provide sufficiently accurate results while coping with the scale and complexity. This talk will focus on some novel techniques in high-performance network modeling and simulation. One is hybrid network traffic modeling, which can offload the computationally intensive bulk traffic calculations to the background onto GPU, while leaving detailed simulation of network transactions in the foreground on CPU. The other is distributed network emulation with simulation symbiosis, which uses an abstract network model to coordinate distributed emulation instances with superimposed traffic model to represent large-scale network scenarios.
