- Setup will be as shown in Figure [1]
(40P) Pre-defined servers
- AIM: Http requests from different clients will be directed to different pre-defined servers
$ sudo mn --topo single,6 --mac --arp --controller remote
$./pox/pox.py log.level --DEBUG misc.ip_loadbalancer --ip=10.0.1.1 --servers=10.0.0.1,10.0.0.2
- Start HTTP servers on h1, h2
mininet> xterm h1
mininet> xterm h2
h1$ python –m SimpleHTTPServer 80
h2$ python –m SimpleHTTPServer 80
- Get webpage from clients (h3)
mininet> xterm h3
h3$ curl 10.0.1.1
- Observe in Pox controller, which server is it connecting to. Continue to obtain webpage from the same client and one other client and observe the results
- Are both servers getting an equal share
(60P) Modified Load_balancer
- Now modify pox/pox/misc/ip_loadbalancer.py to select server in a round robin fashion
