Abstract. Because well-considered optical buffers have not been developed to date, the optical circuit switching (OCS) mechanism has been used widely for data transmission applications in existing optical network-on-chip (ONoC) devices. Unfortunately, with increasing network loads and increasing numbers of intellectual property (IP) cores, ONoCs based on the OCS mechanism are facing serious node congestion problems that greatly limit their network communication performances. A chain-building scheme is proposed to achieve high chain-building efficiency with low overheads. The proposed scheme uses a network state partitioning method based on time prediction to optimize the chain-building process and performs congestion control using a dynamic back-off approach. The simulation results obtained using OPNET software show that the network delay and throughput performances of the ONoC device using the proposed chain-building scheme represent significant improvements when compared with common existing schemes.

基于网络状态划分的动态回退建链方案

摘要。由于迄今为止尚未开发出经过深思熟虑的光缓冲器，因此光电路交换 (OCS) 机制已广泛用于现有片上光网络 (ONoC) 设备中的数据传输应用。不幸的是，随着网络负载的增加和知识产权（IP）核数量的增加，基于OCS机制的ONoC面临严重的节点拥塞问题，极大地限制了其网络通信性能。提出了一种建链方案，以实现低开销的高建链效率。所提出的方案使用基于时间预测的网络状态划分方法来优化链构建过程并使用动态回退方法执行拥塞控制。
