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

VoIP Device

Logical Model of Simulated Network

���������� �����������������������

Automated Application Profiling

Response time at different

bandwidth levels

Level of latency & bandwidth that service level is

met

Summary – Shunra Technology

Shunra Virtual Enterprise technology allows to capture, model & simulate your network

Empirical simulation – run the actual application traffic & feel the end-user experience

Application profiling & service level prediction by automating load tools over simulated network

Optimize by simulating QoS, MPLS, Data-Center Relocation, and other models
