// The guts of the application is dealing with packets, here is a simple
// class for reading records out of the database. Note that the WritePacket()
// methods in VTSDB do not use this object type, it is easier to simply pass
// the entire NPDU in and let the database figure out how to save it.
//
// Packets are created when there is data going out from or going into the
// application from the network. It is independant of the client/server bindings,
// so the old concept of 'upstream' and 'downstream' packets is defunct.
//
// For LAN ports, both the source and destination addresses are filled in. Both
// will be null for PTP ports.
