A novel technique for optical header multiplexing using coded Frequency Division Multiplexing in optical packet switching networks

摘要

The typical labeled optical packet switching requires only the header separation at the core node without touching a payload. Thus labeled optical switching is a promising approach to switch and route optical packets in optical packet switching networks. This paper proposes a novel optical header multiplexing technique by Coded Frequency Division Multiplexing (CFDM) with the biased 8B/10B coding system. The proposed multiplexing technique is performed by 8:1B/12B coding system, and a low pass filter is used for separating the header. To verify that the proposed header multiplexing technique can achieve efficient system performance, we perform simulations and an analysis with respect of 8B/10B coding system. In conclusion, this paper presents a structured engineering result for the optimal multiplexing technique that can make labeled optical packet switching technology commercially more attractive.
