public class UDPPacketHeader

extends java.lang.Object

UDP (Not JCP) Packet header, i think this is legacy from UDP discovery, now superceded by equip.discovery (cmg).

  // 3   24 bits, magic +
  // 1    8 bits, version
  char magic[3], version;
  // 4   32 bits, originator ip (for forward/bridging)
  PRUint32 src_addr;
  // 2   16 bits, originator port (ditto)
  PRUint16 src_port;
  // 2   16 bits, 0 (padding/future use)
  PRUint16 res0;
  // 4   32 bits, originator session id
  PRUint32 src_sid;
  // 4   32 bits, originator object/message id
  PRUint32 src_mid;
  //      1 bit,  last fragment in object flag+
  // 4   31 bits, fragment # (in object/message)
