Nor did it stop NetPDL:
Another approach to the same problem, here's a paper that describes a
language without all the <> noise:
http://www.cs.cmu.edu/~dbrumley/pubs/gapa-ndss-07.pdf
The packet formats are described in BNF to the degree possible, which
is probably more natural for most computer science types.
It has a built-in programming language which would be easier than
programming in an XML programming language.
It would be nice if there were some middle ground between building in
a toy language and describing packets mostly in code and hand-built
tables. What one wants I think is the equivalent of Lex and Yacc but
less slanted towards parsing programming languages. You would describe
90% of the protocol in BNF, and then write the remaining glue logic in
C or some other language.
