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
���������� �����������������������
Latency Risk – Increase Response Time
Single transaction could take up to 30 seconds regardless of 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

New Methodologies in Network Simulation
Capture Production Network Performance
(MPLS, QoS, Dynamic Routing, …)
Application Server
Client or Load Tool
VoIP Device

Automated Application Profiling
Response time at different
bandwidth levels
Level of latency & bandwidth that service level is
met
