Multi-rate media independent interface over a physical coding sublayer

摘要

A method for inserting ordered sets into a data stream converted from a first rate to a second rate N_A times greater than the first rate, while conforming to a requirement that symbols be arranged in units of symbol length M, includes receiving, at the first rate, a data packet containing data symbols, receiving Y₁ symbols of control information, and identifying an ordered set based on the Y₁ symbols. The method also includes generating N_A repetitions of each data symbol of the data packet, determining whether Y₁*N_A/M has a non-zero remainder, and, at least partially in response to determining that Y₁*N_A/M has a non-zero remainder, generating a number of repetitions of the ordered set containing either more or fewer than Y₁*N_A symbols. The method also includes outputting, at the second rate, the data symbol repetitions and first ordered set repetitions.
