A Testbed For Policy Closed Loop Network Management

2

Outline of the presentation

In this presentation we will cover the following points:

• Paper Contribution
• System Architecture
• Network Configuration and Scenario
• The Policy and Decision
• Future Work
• Demo and Questions

3

Contributions of our Work

• Straightforward method to test management policies
• Test bed for the deployment of policies
• onto realistic networks
• Quick evaluation of policies
• through real time monitoring

4

System Architecture

5

Network Configuration and Scenario

• Mininet hosts, switches and links are created and

handled by Floodlight controller

• VLC Player is used to stream video across the network

6

Network Configuration and Scenario

• Central link is confgured with a restricted bandwidth
• While both paths are open the video stream is not

negatvely afected by the restricton

7

Network Configuration and Scenario

• During the video stream a central link is brought down
• Forcing both video streams to travel over the

restricted link

8

The Policy Component

9

SLA Decision

• Analyses customer context information to ensure no

customers have violated Service Level Agreements

• Identifies the customer furthest from violating their SLA
• Restriction of identified customer, granting optimal

bandwidth for the other stream

10

Priority Decision

• Analyses customer context information to extract customer

priority status

• Customers who are not prioritised are identified
• Restriction of customers without priority, leaving the

prioritised customer stream unaffected.
