This problem has occurred because it specifies the wrong format in the packet. You do not specify the ryu.lib.packet.packet.Packet class object to packet. When generating a packet, call the serialize method of the object and generate the byte sequence. Just for your infomation, how to use Generation of Packets (Serialization) is described in the following document. http://shinpeimuraoka.github.io/ryu-book/en/build/html/packet_lib.html#generation-of-packets-serialization thanks, On 2016年02月14日 19:18, Stas Kozlov wrote: > Hi, All > > What is data format for ofp_parser.OFPPacketOut()?
