The Need for Network Simulation
Applications are deployed while ignoring network effects
Issues exposed only in production
Unsatisfied users & unexpected expenditures
Congestion
Loss
Latency
Bandwidth

What is Network Simulation?
1. Creation of the network in a lab environment
2. Empirical simulation of network effects
3. Analyze application performance & user experience
4. Optimize application & network
