“…SDN is a paradigm rather than an implementation or design, which drives to different proposals. Authors [3,5,6,8,14] propose a solution based on a centralized Controller. Authors in [7,9,13] address distributed approaches, aiming to improve scalability.…”

A Systemic and Secure SDN Framework for NoC-Based Many-Cores

2020

Recent exploration of Software-Defined Networking (SDN) for Many-Core Systems-on-Chip (MCSoCs) showed higher management flexibility and reduced physical complexity compared to other runtime communication management. In SDN, there is a software SDN Controller (control layer) that configures generic routers (data layer). The adoption of SDN makes the path establishment programmable and straightforward, according to different network policies, such as low power, QoS, fault-tolerance. It is also possible to change the path establishment policies at runtime without the need to redesign the NoC. Current works focus on proposing SDN architectures, lacking a systemic framework that describes the steps required to implement SDN into a Many-core environment. Security is an observed gap in SDN designs. A malicious task could configure SDN routers and take control of the NoC. The contribution of this work is to present a systemic and secure SDN framework (SDN-SS), detailing the steps required to support SDN in MCSoCs. This work also describes the iteration between the hardware, operating system, and user's tasks. The SDN-SS manages a Multiple-Physical NoC, with one packet-switching subnet and a set of circuitswitching subnets. The originality of SDN-SS includes (i) a step-by-step framework description addressing the phases required to support a secure SDN management; (ii) a secure SDN router configuration protocol; (iii) a protocol to change the subnet at runtime. Experimental results show the framework's capability to avoid DoS and Spoofing attacks while presents a low SDN router configuration overhead, corresponding up to 2% of a related work delay and a small impact over the user's task communication.

“…Authors [6,9,13,14] propose generic SDN management, without specializing the SDN architecture to a specific constraint, focusing on investigating the pros and cons of the SDN paradigm for intra-chip communication. On the other hand, Scionti et al [7] address SDN for power savings by switching off links not used.…”

“…The authors use the SDN approach as a routing method and they made a comparison between SDNoC and static XY routing and dynamic DyAD routing with traditional NoC architecture. Afterwards in [9], the authors applied SDN principles in order to propose a SDNoC architecture. This architecture is focused on abstraction layers and interfaces that permit its deployment in a modular fashion and it has the potential to overcome the NoC management problems in the many-Core era.…”

System on chips (SoCs) are all around us in today's world. Therefore, in this paper we propose a flexible, technologyaware SoC design, named as Cloud-of-Chips (CoC), which is able to change its characteristics, such as routing logic, transmission paths, priorities, IC clustering, etc. We focus particularly on inside communication of CoC architecture. The basic idea of CoC is the creation of an architecture, which will be able to support all the requirements of a vast number of todays applications by adopting and changing its characteristics according to them. The valorization perspectives are of importance since the outcomes of this research will be applicable for embedded systems, realtime systems, communication systems, as well as for mainstream systems such as Internet-of-Things and Internet-of-Everything. As far as the inside communication of our CoC platform is concerned, we leverage on algorithms and strategies developed within the field of Software Defined Networking (SDN), which was introduced to deal with hardware redesign and ultimately provide cloud-like flexibility. At the end, we describe registration and authentication of every entity in our network.

“…Specifically Cong et al propose a SDNoC architecture where the control plane is deployed as a distributed unity at each router; however this is contrary to SDN philosophy because both planes are placed inside the router. Afterwards Sandoval et al [7,8] propose an SDNoC architecture which consists of three layers: Operating System, Network Operating System, and Infrastructure. In this research the authors made an assumption that the routers need configuration data by the SDN controller.…”

In recent years, Multi-Processor System-on-Chips (MPSoCs) are widely deployed in safety-critical embedded systems. The Cloud-of-Chips (CoC) is a scalable MPSoC architecture comprised of a large number of interconnected Integrated Circuits (IC) and Processing Clusters (PC) destined for critical systems. While many researches have focused on addressing the hardware issues of MPSoCs, the communication over them has not been very well explored. Following the SDN concept, we propose a new protocol in order to secure the communication and efficiently manage the routing within the CoC. The SSPSoC includes a private key derivation phase, a group key agreement (GKA) phase, and a data exchange phase in order to ensure that basic security primitives are preserved and provide secure communication. Furthermore, a network of 1-30 nodes is set in order to validate the proposed protocol and measure the network performance and memory consumption of the proposed protocol.
