Totally a newbie

[eoluak]

Hello, I caught interest in your work and I will like to test run it. Can you guide me on how to do this?

Sorry to ask dumb question.

Hi!

First of all i am glad you caught interest in this project.

If is your first time with SDNs you should learn it first.

If is your first time with floodlight, I recommend this tutorial: http://networkstatic.net/tutorial-to-build-a-floodlight-sdn-openflow-controller-module/

This project was developed using a testbed, but you can use mininet (serach minet is google and youu will find it).

Just download the project and import it in eclipse. I dont quite remember all the configuration needed, it (is been a long time since last time I worked on it). Nevertheless you have install some scripts (they are at the scripts folder), some for the switches and some for the hosts.

The switch's scripts are used to calculate the bandwidth while the others are used to retrieve important stats about the hosts like cpu load.

The bandwidth calculation is not the best way to do it. If you want, do not use the scripts and make the controller periodically ask for switche's port Statistics, and analise the bits/s.

I think this is all, if you have any difficulties feel free to ask me.

Best regards Gonçalo Semedo

Thanks for your quick response.

I will give it a try. I am familiar with SDN. I usually just clone projects and try them out. Not a fan of programming as such, but I will have it loaded to eclipse and see what I can make of it.

Many thanks.

I will get back to you if I have any concerns.

Cheers.

Hi, I have been able to get the project up and running, but I have a few extra guide I'll like to request from you or anyone in this project. How do I find the service tables, so I can add entries and where also is the REST API used. Thanks

Hi,

Have you configured the load balancer module as described in https://floodlight.atlassian.net/wiki/display/floodlightcontroller/Load+Balancer ?

After that you need to add services using curl:

curl –x POST –d '{"service_name":" BioApp ","algorithm":"3","port":"6789"}' http:///quantum/v1.0/services/

where service name can be anything you like;

algorithm is the identifier of the algorithm you want to use:

Algorithm - 1: Shortest Latency-Path Server (SL-PS): chooses the server whose path between itself and the client offers the lowest latency.

Algorithm - 2: Highest Throughput-Path Server (HT-PS): chooses the server whose path between itself and the client has the best throughput.

Algorithm - 3: Least CPU usage (CPU): in this algorithm, the server is with lowest CPU usage is chosen.

And finally the port is what the application use to identify the flow, for example:

All the packets with destination port 80, use the Shortest Latency-Path Server algorithm.

Best regards

Hello.

I have been able to get the concept of the REST API. I had issues with the permission on the project folder, that's why I wasn't achieving success, but I have been able to rectify that out.

I hope this will be the final question coming from me as regards this project...lol

How do I test run these three algorithms after defining adding the services?

Like the floodlight balancer - they were able to use 'h1 ping -c1 10.0.0.100'

Warm regards Emmanuel

Hi,

When I did this project, I used wget to make http requests (latency test), FTP (bandwidth test) and a genom treatment program (cpu test).

Just make clients do different types of requests to servers.
