Abstract:
1. A method for transporting data, comprising: receiving client data at a first rate; buffering the client data; retrieving the client data; combining the client data with dummy data; and transmitting the combined data at a second rate; wherein the combined data is transmitted according to a repeating pattern, wherein the pattern comprises K successive blocks, wherein a first number, R, of the K blocks contain a first amount, P, of client data, wherein a second number, K-R, of the K blocks contain a second amount of client data; the method further comprising: determining a size of a payload, L, of a unit under operation and an amount of client data, N, to be mapped into the payload of the unit under operation; determining a number M of full w-bytes of client data in N, where w is the width of a transport medium over which the combined data is transmitted; determining P and the second amount of client data, P+1, where P is M divided by K, rounded down; determining the first number, R, and second number, K-R, of blocks, where R is the remainder of M divided by K; and if N is not evenly divisible by w, determining a residual amount of client data, r, where r is equal to the remainder of N divided by w, wherein the pattern further comprises a residual slot containing r bytes of client data.
