Half-step fotward switch in EPFTS
Dengyuan Xu, Benniu Zhang · 2009
Most of works, such as looking-up table, queuing and scheduling, are dealt with in traditional switch in serial, which makes the handling capacity in traditional switch become the bottle affecting the switch performance. A novel switch technique called half-step forward switch (HFS) is proposed in this paper to optimize the switch process. HFS makes looking-up table and scheduling be dealt with in parallel, which can relieve the works in switch and can reduce delay and delay jitter in switch node. Simulation results shows that HFS switch can reduce by 6.7% in average delay and reduce by 8.1% in delay jitter compared to conventional switch.
