泛洪速度过快时服务器无法解析数据包

Question

这是我每秒用太多数据包淹没服务器时得到的错误：2014/11/28 12:52:49 main.go:59: loading plugin: print2014/11/28 12:52:49 main.go:86: starting server on 0.0.0.0:80802014/11/28 12:52:59 server.go:15: client has connected: 127.0.0.1:591462014/11/28 12:52:59 server.go:43: received data from client 127.0.0.1:59146: &main.Observation{SensorId:"1", Timestamp:1416492023}2014/11/28 12:52:59 server.go:29: read error from 127.0.0.1:59146: zlib: invalid header2014/11/28 12:52:59 server.go:18: closing connection to: 127.0.0.1:59146它设法解码一个数据包（有时，可能是 2 或 3 个）然后出错。这是进行泛洪的代码：import socketimport structimport jsonimport zlibimport timedef serialize(data):    data = json.dumps(data)    data = zlib.compress(data)    packet  = struct.pack('!I', len(data))    packet += data    return len(data), packetmessage = {    'sensor_id': '1',    'timestamp': 1416492023,}length, buffer = serialize([message])client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)client.connect(('127.0.0.1', 8080))while True:    client.send(buffer)    #time.sleep(0.0005)当我取消对time.sleep()调用的注释时，服务器工作正常。似乎每秒太多的数据包正在杀死服务器。为什么？这是相关的 Go 代码。连接处理程序：func (self *Server) handleConnection(connection net.Conn) {    for {        connection.SetReadDeadline(time.Now().Add(30 * time.Second))        observations, err := self.Protocol.Unserialize(connection)        if err != nil {            log.Printf("read error from %s: %s\n", connection.RemoteAddr(), err)            return        }}这是反序列化程序：// Length Value protocol to read zlib compressed, JSON encoded packets.type ProtocolV2 struct{}func (self *ProtocolV2) Unserialize(packet io.Reader) ([]*Observation, error) {    var length uint32    if err := binary.Read(packet, binary.BigEndian, &length); err != nil {        return nil, err    }    buffer := make([]byte, length)    rawreader := bufio.NewReader(packet)    if _, err := rawreader.Read(buffer); err != nil {        return nil, err    }
