ABSTRACT:
A persistent packet provides a wrapper that may be interpretable by an application, a packeting process, a database engine, or a device intermediate a sending device and a receiving device. Accordingly, the packet may be transferred and stored without changing the packet structure. The wrapper contains a header for rapid transfer of the packet with no need for any machine or process to open the packet and access the substantive data contained therein. The wrapper also contains application-specific data that may be interpreted by the packeting process or the application, or both. The application-specific data pertains to the substantive data contained in the packet and may be used by an application in determining how to dispose of a packet. For example an application may determine whether to store, open, discard, etc. the packet. The application-specific data may also be used by an application in a process of disposition of a packet. Both the header and application-specific data in the wrapper may be persistent across processes and apparatus. An application may "sub-contract" packeting to a separate packeting process, yet the application remains the "owner" of the packet.
