This memo   does not specify an Internet standard of any kind.  Distribution of   this memo is unlimited.Abstract   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   (SONNET).Protocol Overview   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   pronounced "owch."   Mapping of the 2**704 possible SONET payloads is achieved by matching   each possible payload pattern with its equivalent Cerf catalog number   (see [1], 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,...   For rates higher than OC-1, the OC-1 frames may either come   interleaved or concatenated into larger frames.  Under SONNET   conversion rules, interleaved frames have their corresponding sonnet   representations interleaved.  Thus SONET frames 33, 29 and 138 in an   OC-3 frame would be converted to the sequence:        Full many a glorious morning have I seen        When, in disgrace with fortune and men's eyes,        When my loves swears that she is made of truth        Flatter the mountain-tops with sovereign eye        I all alone beweep my outcast state,        I do believe her, though I know she lies        Kissing with golden face...   while in an OC-3c frame, the individual OC-1 frames concatenated, one   after another, viz.:        Full many a glorious morning have I seen Flatter the mountain-        tops with sovereign eye Kissing with golden face...        When, in disgrace with fortune and men's eyes, I all alone
                                 beweep my outcast state,...        When my loves swears that she is made of truth I do believe her,        though I know she lies...   (This example, perhaps, makes clear why data communications eXPerts   consider concatenated SONET more efficient and esthetically   pleasing).Timing Issues   It is critical in this translation scheme to maintain consistent   timing within a frame.  If SONET frames or converted sonnets shift in   time, the SONET pointers, or worse, poetic meter, may suffer.References   [1] Cerf, B., "A Catalog of All Published English Sonnets to 1950",       Random House, 1953.
