SONET to Sonnet Translation
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
Because Synchronous Optical Network (SONET) transmits data in frames
of bytes, it is fairly easy to envision ways to compress SONET frames
to yield higher bandwidth over a given fiber optic link. This memo
describes a particular method, SONET Over Novel English Translation
In brief, SONNET is a method for compressing 810-byte (9 lines by 90
bytes) SONET OC-1 frames into approximately 400-byte (fourteen line
decasyllabic) English sonnets. This compression scheme yields a
roughly 50% average compression, and thus SONNET compression speeds
are designated OCh-#, where 'h' indicates 50% (one half) compression
and the # is the speed of the uncompressed link. The acronym is
Mapping of the 2**704 possible SONET payloads is achieved by matching
each possible payload pattern with its equivalent Cerf catalog number
(see , which lists a vast number of sonnets in English, many of
which are truly terrible but suffice for the purposes of this memo).
Basic Transmission Rules
The basic transmission rules are quite simple. The basic SONET OC-1
frame is replaced with the corresponding sonnet at the transmission
end converted back from the sonnet to SONET at the receiving end.
Thus, for example, SONET frame 12 is transmitted as:
When do I count the clock that tells the time
And see the brave day sunk in hideous night;
When I behold the violet past prime,
And sable curls,...
