Re: Quantifying OSI

Yes, John Larmouth of the UK had left the basic ASN.1 syntax a total mess. Uncompilable. First that had to be straightened out.

But what proved to be much more important was PER, which was much more compact (compressing it often got larger) and less processing overhead.
The purists liked BER. 
Today there are 10s of encoding rules for ASN.1.

Take care,
John
