【SDN课设】正式开始第一步:源码解析+arp回复
正式开始 ryu源码分析之packet类 ryupacket源码 ryu packet文档 结合这个例子学习构造包下发 逐级封装: e = ethernet . ethernet ( dst = 'ff:ff:ff:ff:ff:ff' , src = '08:60:6e:7f:74:e7' , ethertype = ether . ETH_TYPE_ARP ) a = arp . arp ( hwtype = 1 , proto = 0x0800 , hlen = 6 , plen = 4 , opcode = 2 , src_mac = '08:60:6e:7f:74:e7' , src_ip = '192.0.2.1' , dst_mac = '00:00:00:00:00:00' , dst_ip = '192.0.2.2' ) p = packet . Packet ( ) p . add_protocol ( e ) p . add_protocol ( a ) 添加action事件下发包 actions = [ parser . OFPActionOutput ( port = port ) ] out = parser . OFPPacketOut ( datapath = datapath , buffer_id = ofproto . OFP_NO_BUFFER
