* (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.py log.level –-DEBUG misc.ip_loadbalancer –-ip=10.0.1.1 –-servers=10.0.0.1,10.0.0.2 | |||

*** > xterm h1,h2 | |||
*** h1$ Python –m SimpleHTTPServer 80 | |||
*** h2$ Python –m SimpleHTTPServer 80 | |||
** Get webpage from clients (h3) | |||
*** > xterm h3 | |||
*** h3$ Curl 10.0.1.1 | |||
** Observe in Pox controller, which server is it connecting to. Continue to obtain webpage from other clients and observe the results | |||
