I updated with all the feedback and here is a version 1.0 pdf
specification. I appreciate any comments or suggestions you may
have for this.

Thank you,

More,
sorry. I left out the msgSize in the FEC spec. Let me reorder
the tagging, fit the 3 bytes of normal msgSpec into 4bytes and
thusly...
---Default non-FEC msgSpec + header + payload layout:
- 8bytes (X) messageSpecification...
-
- (32bits...)
- 4bits tagging
- 6bits multicastSymbol
- 6bits messageVersion
- 2bits sanguinity
- 6bits headerType "Implies Y header size. NOTE: except for FEC
encodings"
- 8bits unused
- (32bits...)
- 4bytes messageSize (X+Y+Z) (Z bytes = (messageSize -
headerSize(Y) - 8bytes msgSpec (X = 8))
-
- Ybytes message header https://www.dropbox.com/s/ywu9pjxrfvg1hys/FrameTypes.pdf?dl=0
-
- Zbytes message payload
Special FEC coded 64bit <msgSpec + header> + payload
layout, for 64bit alignment:
- 8bytes (X) message specification...
-
- (32bits...)
- 4bits tagging
- 6bits multicastSymbol
- 6bits messageVersion
- 2bits sanguinity
- 6bits FEC message type "NOTE: this means different layout"
- 2bits rsMode
- 6bits partial blockCount
- (32bits...)
- 4bits blockCount "NOTE: for 1MB encoded/982KB data -
blockCount * blockCodeBytes = Z"
- 20bits messageSize (X+Y+Z) (Z bytes = (messageSize -
headerSize(Y) - 8bytes msgSpec (X = 8)) "NOTE: this can specify
1MB data"
- 8bits primitivePolynomial spec (good for our current rsModes)
-
- Y = 0
-
- Zbytes-sized payload
Ok, that's what it is I think, this proposal.
