实验6:开源控制器实践——RYU

作者:互联网

实验目的

二、实验环境

三、实验要求

      from ryu.base import app_manager
      from ryu.controller import ofp_event
      from ryu.controller.handler import MAIN_DISPATCHER
      from ryu.controller.handler import set_ev_cls
      from ryu.ofproto import ofproto_v1_0

      class L2Switch(app_manager.RyuApp):
          OFP_VERSIONS = [ofproto_v1_0.OFP_VERSION]

          def __init__(self, *args, **kwargs):
              super(L2Switch, self).__init__(*args, **kwargs)

          @set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
          def packet_in_handler(self, ev):
              msg = ev.msg
              dp = msg.datapath
              ofp = dp.ofproto
              ofp_parser = dp.ofproto_parser

              actions = [ofp_parser.OFPActionOutput(ofp.OFPP_FLOOD)]

              data = None
              if msg.buffer_id == ofp.OFP_NO_BUFFER:
                   data = msg.data

              out = ofp_parser.OFPPacketOut(
                  datapath=dp, buffer_id=msg.buffer_id, in_port=msg.in_port,
                  actions=actions, data = data)
              dp.send_msg(out)
