Communication among nodes plays an important role in any system's throughput. In some architecture, communication plays a bottleneck which degrades the computation power. However, making a high-performance computational system along with the energy-efficient system is incompatible in many cases. In this paper, we present a routing methodology in an optical networks on chip (O-NoC). The proposed methodology includes architectural design as well as algorithms working on that architecture. These algorithms are used to communicate among nodes, which eliminates path reservation criteria and provides guaranteed communication. Under some criteria, our methodology achieved excellent results in reducing design space complexity. Furthermore, we evaluated our results on synthetic traffic patterns which include random uniform and hotspot traffic patterns. The proposed methodology achieves better results in case of reduction in hop count between nodes, 100 % link utilization which eliminates ideal node and reduces algorithm running time that makes architecture more energy efficient. These achieved results may enhance computation power and communication power at the same time in O-NoC.

节点之间的通信在任何系统的吞吐量中都起着重要作用。在某些体系结构中，通信成为瓶颈，降低了计算能力。但是，在许多情况下，将高性能计算系统与节能系统一起使用是不兼容的。在本文中，我们介绍了片上光网络（O-NoC）中​​的路由方法。所提出的方法包括体系结构设计以及在该体系结构上工作的算法。这些算法用于在节点之间进行通信，从而消除了路径保留标准并提供了有保证的通信。在某些条件下，我们的方法在降低设计空间复杂性方面取得了优异的成绩。此外，我们评估了综合流量模式的结果，其中包括随机统一流量和热点流量模式。如果减少节点之间的跳数，100％的链路利用率（这消除了理想的节点并减少了算法的运行时间，使体系结构更加节能），则所提出的方法可获得更好的结果。这些获得的结果可以在O-NoC中同时提高计算能力和通信能力。
