High performance and flexible FPGA-based time shared optical network (TSON) metro node

The paper presents the architecture, implementation and evaluation of the flexible and finely granular Time Shared Optical Network (TSON) metro node. It focuses on the FPGA-based Layer 2 TSON metro node system. The experimentally measured results show exceptional performance of up to 8.68Gbps throughput per 10Gbps port, 95.38% of theoretical maximum throughput, latency of less than 160μsec and jitter of less than 25μsec. The TSON topology agnostic node/network also delivers differentiated QoS latency levels yet always guaranteed (contention-free) by deploying diverse time-slice allocation schemes.
