“…However, the objective of finding a general platform that suits any network for flexible chip control had a great deal in the research community. Researchers found that the concept of Software Defined Networks (SDN) can be applied to NoC [17], [18], [19], and [20]. The combination of these concepts produced a novel NoC management technology, which was called Software Defined Network on Chip (SDNoC) [21] and [22].…”

Photonic networks and software-defined networks are two promising technologies to improve network-onchips performance, scalability, and resource utilization. Several architectures suffer from scaling limitations, high-power consumption, and noise interference drawbacks. In this paper, an enhanced photonic network-on-chip architecture called (SD-PNoC) is presented. The proposed architecture based on a hybrid hardware-software approach, and a Software-Defined Management Orchestrator (SDMO) to separate the network control and data forwarding planes. This orchestrator has hosted on the upper hardware router as a virtual layer capable of dynamic management. It reconfigures data forwarding paths and allows dynamic execution of different algorithms in real-time, as it scales the proposed topology based on both applications and the network requirements. The proposed SD-PNoC architecture, hierarchical communication protocols, and orchestrator management policies were implemented, simulated, and tested using a customized Phoenix-SIM framework in the OMNIT++ simulation environment. Numerous simulation experiments under different conditions have been performed and have proven that the performance of the proposed architecture is better than that of the conventional electronic network on chip (ENoC). Furthermore, simulation results without using the management policies showed that the latency is reduced by 46% and 25.5% for the 4x4 and 8x8 network structures, respectively. While the power consumption is reduced by 76.5% and 78.5% for the 4x4 and 8x8 network structures, respectively. Besides, the chip area is reduced by 33.4%. Moreover, simulation results of SDMO with using the management policies for the 8x8 network structures increased the enhancement of latency from 25.5% to 37.3% and the power consumption from 78.5% to approximately 80%, which assure the ability of the proposed architecture to remarkably enhance the overall performance of complex network-on-chip structures.

SDN-Based Secure Application Admission and Execution for Many-Cores

General-purpose many-core system-on-chip (MCSoC) requires support to the execution of dynamic workloads, i.e., admission of new applications at runtime. Some applications may require QoS and security from the MCSoC, not tolerating that malicious tasks or hardware Trojans steal or corrupts their data. A robust method to provide security is to isolate the communication and computation. Most current works employ such isolation in continuous regions named secure zones (SZ). Motivated by the recent study of the Software-Defined Networking (SDN) paradigm for MCSoCs, this work proposes to use SDN-based management to implement the communication isolation at runtime. The computation isolation occurs by mapping only tasks of the same application at each core. The communication isolation is supported by the SDN paradigm, which establishes dedicating paths for secure applications. Results show that the SDN-based approach presents a negligible latency to admit and execute a secure application, with a reduced hardware cost and higher computational resources utilization compared to SZs.
