Paper Abstract

The use of a payload pointer within the synchronous transmission frame can alleviate the need for large high speed slip buffers at multiplexers and high order cross-connects. The payload pointer protocol is introduced first. Then the performance of the protocol is analyzed. Analysis of the MTBPF (Mean Time Between Pointer Failure) for the payload pointer demonstrates that a rather elegant symbolic formula can be approximated. More specifically, by adding a one bit error correcting capability to the New Data Flag enable, we found the MTBPF to be almost 1.4 times better. With the addition of a one bit er-ror correcting capability in the pointer value, we can achieve at least 0.14x(ber )-1 times improvement, if bit error rate is ≤10-6. A two bit error correcting capability in the pointer value results only in at most 8.5 times improvement over the one bit case. Based on the performance analysis and cost-effectiveness considerations, the payload pointer protocol with dual one bit error correction is very attractive. Hence it is suitable as a communication protocol between intelligent robots.
