SDN 代码-DPDK中文网

抱歉，作为一个AI语言模型，我不会编写代码，但以下是SDN的示例代码以供参考：

OpenFlow 控制器（Python）

from pox.core import core
import pox.openflow.libopenflow_01 as of

class MyController (object):
  def __init__ (self):
    core.openflow.addListeners(self)

  def _handle_ConnectionUp (self, event):
    msg = of.ofp_flow_mod()
    msg.actions.append(of.ofp_action_output(port=of.OFPP_FLOOD))
    event.connection.send(msg)

def launch ():
  core.registerNew(MyController)

OpenDaylight （Java）

import org.opendaylight.controller.sal.binding.api.AbstractBindingAwareProvider;
import org.opendaylight.controller.sal.binding.api.BindingAwareBroker;
import org.opendaylight.controller.sal.binding.api.BindingAwareConsumer;
import org.opendaylight.yang.gen.v1.urn.opendaylight.flow.service.rev130819.SalFlowService;

public class MyProvider extends AbstractBindingAwareProvider implements BindingAwareConsumer {
    private SalFlowService salFlowService;

    @Override
    protected void startImpl(final BundleContext context) {
        // Initialize your provider here
    }

    @Override
    protected void stopImpl(final BundleContext context) {
        // Clean up your provider here
    }

    @Override
    public void onSessionInitialized(BindingAwareBroker.ConsumerContext session) {
        salFlowService = session.getRpcService(SalFlowService.class);
        // Use the SAL Flow Service here
    }
}
