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).

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 h...
