【Abstract】With the development of the Internet of Things, trust has become a limited factor in the integration of heterogeneous IoT networks. In this regard, we use the combination of blockchain technology and SDN/NFV to build a heterogeneous IoT network resource management model based on the consortium chain. In order to solve the efficiency problem caused by the full amount of data on the chain, we deploy light nodes and full nodes for the consortium chain. At the same time, we use the idea of identification to realize the separation of identification and resource information, build the application mode of on-chain identification and off-chain information, and realize resources endogenous trust management. We also propose a practical Byzantine fault-tolerant consensus mechanism based on reputation value to save consensus costs and improve efficiency. Combined with artificial intelligence technology, we introduce deep reinforcement learning for service function chain orchestration, and design a service function chain orchestration algorithm based on Asynchronous Advantage Actor-Critic to optimize orchestration costs. The final simulation results show that the consensus algorithm and service function chain orchestration algorithm we designed have good performance in terms of cost saving and efficiency improvement.

【标题】基于内生可信的DRL的物联网服务功能链编排
【摘要】随着物联网的发展，信任已经成为异构物联网网络整合的一个有限因素。对此，我们利用区块链技术和SDN/NFV的结合，构建了基于联盟链的异构物联网网络资源管理模型。为了解决链上全量数据带来的效率问题，我们为联合体链部署了轻节点和全节点。同时，我们利用识别的思想，实现了识别与资源信息的分离，构建了链上识别与链下信息的应用模式，实现了资源内生的信任管理。我们还提出了一种实用的基于信誉值的拜占庭容错共识机制，以节省共识成本，提高效率。结合人工智能技术，我们为服务功能链协调引入了深度强化学习，并设计了一种基于异步优势演员批评的服务功能链协调算法，以优化协调成本。最终的仿真结果表明，我们设计的共识算法和服务功能链协调算法在节约成本和提高效率方面有良好的表现。
