RFC5050 3.1 -- DefinitionsBundle is composed of 'blocks' -- block format and concatenation.X
10
RFC5050 4.0 -- Bundle FormatEach bundle has at least two block structuresX
11
First block must be the primary bundle blockX
12
No bundle may have more than one primary bundle blockX
13
At most one payload blockX
14
Only the block in sequence must have 'last block' bit set to one; all others (except primary) must have 'last block' set to zero.X
15
RFC5050 4.2 -- Bundle Processing Control Flags0 - Bundle is a fragment
16
1 - Application data unit is an administrative record
17
2 - Bundle must not be fragmented

RFC5050 4.4 -- Endpoint IDsEndpoint IDs are text strings identified by <scheme name>:<scheme-specific part>
Note: this is how Endopoint IDs are expressed to the user / application or in the dictionary when NOT using CBHE.
X
30
EIDs stored in dictionary of primary bundle block -- references are first, last character index.
31
dtn:none is supported
32
RFC5050 5.8 -- Bundle FragmentationConcatenation of fragment payloads == original payloadX
33
Bundle processing flags of primary blocks of fragments have the fragment bit set.
34
Fragment offsest and total ADU length set in primary bundle blocks of fragments.
35
All blocks that precede the payload block at the time of fragmentation must be replicated in the fragment with the lowest offset
36
All blocks that follow the payload block at the time of fragmentation must be replicated in the fragment with the highest offset.
37
If the 'Block must be replicated in every fragment' bit is set to 1, then the block must be replicated in every fragment.
38
If the 'Block must be replicated in every fragment' bit is set to zero, the block should be replicated in only one fragment.
39
The relative order of all blocks that are present in a fragment must be the same as in the bundle prior to fragmentation.

51
RFC5050 4.6 -- Extension BlocksWhenever a bundle is forwarded that contains one or more extension blocks that could not be processed, the "Block was forwarded without being processed" flag must be set to 1 within the block processing flags of each such block
52
For each block flagged in this way, the flag may optionally be cleared (i.e., set to zero) by another node that subsequently receives the bundle and is able to process that block
