Summary:
In the paper a simulation of the data link layer for a 100Gbps wireless network is presented. The overhead of protocols and coding should be reduced to a minimum. This maximizes a link throughput. This is especially important for high-speed networks, where a small degradation of efficiency will degrade the throughput by several Gbps. Three major aspects are explained: an acknowledge frame compression, the optimal size of the frame segments, Reed-Solomon forward error correction codes with an algorithm to control the transmitted data redundancy. The most important observation is that changing the segment size influences the uncoded transmissions mostly. The transmissions coded with the Reed-Solomon block codes are less sensitive to the segment size. In the last paragraph, an algorithm for controlling the Reed-Solomon redundancy is presented. Predictable error performance of the codes allows implementing an accurate solution based on an error statistic.
