hope this fix your issue This kind of thing is normally done using a separate firewall (e.g. in a router or gateway box) or firewall software running on one or both of the client machines.
This is not the sort of thing that it is sensible to implement in Java.

seems to work fine I suspect this may be due to the Nagle algorithm. The following code disables it:
code :
socket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.NoDelay, true);

Deep Packet Inspection Switch in a Software Defined Network with OpenFlow Protocol

will help you I think DPI in SDN environments is mostly used in scenarios where all flows matching some tuple is sent through a DPI box. SDN is more about flow control and traffic engineering than these type of services.
However, you could do DPI using OpenFlow where all traffic were encapsulated (Packet_in, Packet_out) and sent to the controller (with some DPI application) for inspection. This would however not be practical because of the latency connected with the traverse time from device to controller and back again.

will be helpful for those in need The NAL unit loss software was included with earlier version of the HM reference software (in the utils folder).
However, this software was never updated when the NAL unit structure changed in the HEVC standard and is no longer suitable for use without modification.

fixed the issue. Will look into that further Why , First, always check returned errors — it's your feedback:
code :
err := gopacket.SerializePacket(newBuffer, options, packet)
// OR
err := gopacket.SerializeLayers(newBuffer, options,
  ip,
  tcp,
)
// THEN
if err != nil {
  panic(err)
}
package main

import (
  "encoding/hex"
  "github.com/google/gopacket"
  "github.com/google/gopacket/layers"
  "fmt"
  "net"
)

func main() {

  packetData := []byte{
    69, 0, 0, 63, 64, 237, 64, 0, 64, 6, 74, 221, 192,
    168, 1, 90, 52, 85, 184, 151, 141, 230, 0, 80,
    174, 147, 86, 192, 18, 107, 243, 149, 128, 24,
    0, 229, 92, 65, 0, 0, 1, 1, 8, 10, 22, 138, 85, 109,
    48, 16, 32, 253, 49, 50, 51, 52, 53, 54, 55, 56,
    57, 48, 10,
  }

  fmt.Println("Hex dump of real IP packet taken as input:\n")
  fmt.Println(hex.Dump(packetData))

  packet := gopacket.NewPacket(packetData, layers.LayerTypeIPv4, gopacket.Default)
  if ipLayer := packet.Layer(layers.LayerTypeIPv4); ipLayer != nil {
    ip := ipLayer.(*layers.IPv4)
    dst := ip.DstIP.String()
    src := ip.SrcIP.String()

    if tcpLayer := packet.Layer(layers.LayerTypeTCP); tcpLayer != nil {
      tcp := tcpLayer.(*layers.TCP)
      dst = fmt.Sprintf("%s:%d", dst, tcp.DstPort)
      src = fmt.Sprintf("%s:%d", src, tcp.SrcPort)
      fmt.Printf("From %s to %s\n\n", src, dst)

      ip.DstIP = net.ParseIP("8.8.8.8")

      options := gopacket.SerializeOptions{
        ComputeChecksums: true,
        FixLengths: true,
      }

      tcp.SetNetworkLayerForChecksum(ip)

      newBuffer := gopacket.NewSerializeBuffer()
      err := gopacket.SerializePacket(newBuffer, options, packet)
      if err != nil {
        panic(err)
      }
      outgoingPacket := newBuffer.Bytes()

      fmt.Println("Hex dump of go packet serialization output:\n")
      fmt.Println(hex.Dump(outgoingPacket))

    }

  }

}
