Content distribution Over SDN

This code is a first try to implement an API for a content distribution service over SDN. 

-->Rebooting steps:

• up virtual network interface root@server:# ip tuntap add mode tap vnet1 root@server:# ip link set vnet1 up

• (repeat for other virtual network interfaces, for example of vnet2) root@server:# ip tuntap add mode tap vnet2 root@server:# ip link set vnet2 up

• up bridge and bridged interface root@server:# ifconfig eth0 0 up root@server:# cd ./openvswitch/datapath/linux; modprobe openvswitch;cd ;/root/openvswitch.sh
  root@server:# ifconfig br0 192.168.1.20 netmask 255.255.255.0 up

• run floodlight root@server:~# cd /root/floodlight; java -jar target/floodlight.jar

--> Static flow definition:

curl -X POST -d '{"switch":"00:00:30:f9:ed:c6:a3:46", "name":"static-flow3", " cookie":"0", "priority":"32768", "ipv4_src":"192.168.1.24", "eth_type":"0x0800","active":"true","actions":"output=5"}' http://localhost:8080/wm/staticflowpusher/json
