The three-dimensional Network-on-Chips (3D NoCs) has become a mature multi-core interconnection architecture in recent years. However, the traditional electrical lines have very limited bandwidth and high energy consumption, making the photonic interconnection promising for future 3D Optical NoCs (ONoCs). Since existing solutions cannot well guarantee the fault-tolerant ability of 3D ONoCs, in this paper, we propose a reliable optical router (OR) structure which sacrifices less redundancy to obtain more restore paths. Moreover, by using our fault-tolerant routing algorithm, the restore path can be found inside the disabled OR under the deadlock-free condition, i.e., fault-node reuse. Experimental results show that the proposed approach outperforms the previous related works by maximum 81.1 percent and 33.0 percent on average for throughput performance under different synthetic and real traffic patterns. It can improve the system average optical signal to noise ratio (OSNR) performance by maximum 26.92 percent and 12.57 percent on average, and it can improve the average energy consumption performance by 0.3 percent to 15.2 percent under different topology types/sizes, failure rates, OR structures, and payload packet sizes.

基于节点复用的3D光片上网络容错路由机制
三维片上网络(3D NoC)近年来已成为成熟的多核互连架构。然而,传统电线的带宽非常有限且能耗高,这使得光子互连在未来的 3D 光学 NoC (ONoC) 中大有可为。由于现有的解决方案不能很好地保证3D ONoCs的容错能力,在本文中,我们提出了一种可靠的光路由器(OR)结构,它牺牲了更少的冗余来获得更多的恢复路径。此外,通过使用我们的容错路由算法,可以在无死锁的情况下,即故障节点重用,在disabled OR内部找到恢复路径。实验结果表明,所提出的方法比以前的相关工作最高 81.1% 和 33。在不同的合成和实际流量模式下,吞吐量性能平均为 0%。它可以将系统平均光信噪比(OSNR)性能平均提高26.92%和12.57%,在不同的拓扑类型/尺寸、故障率、 OR 结构和有效载荷数据包大小。
