Buffer Fragmentation and Reassembly

In cases where a higher-level transmit application (or higher layer in a communications stack) must transmit a buffer of data that exceeds the JRDDP MTU size, the buffer must be fragmented into a series of JRDDP packets and then reassembled at the receive TEP before returning the buffer to the next higher-level.

Sequence numbers in the JRDDP header assure the correct ordering of individual JRDDP packets within the series of packets that represent the buffer and sequence flags delineate the boundaries of the data buffer within a stream of packets.

A maximum buffer size must be agreed upon by both transmit and receive TEPs to preclude excessive resource allocations.
