G.4.4 Size of the Matrix
The final decision to be made is the size of matrix to be used. The addition of
column only FEC protection, irrespective of the matrix dimensions, considerably
reduces the Mean Time Between Failures (MTBF). The difference in coding gain
between a small matrix and a big matrix is small compared to the considerable gain
of actually adding a FEC scheme. A large matrix would therefore probably be
preferred for most service providers as the IP packet overhead is lower.
