“…FlexE is a pivotal advancement in optical networking that enables the subdivision of Ethernet connections into smaller, flexible sub-connections, each with an independently configurable bandwidth and characteristics [4]. This granular resource allocation empowers network operators to efficiently utilize the physical network infrastructure, thereby accommodating the diverse traffic demands expected in the 6G landscape [5].…”

With the continuous emergence of the concept of 6G, the rapid development of industrial application scenarios, and the rise in demand for dedicated line services, there has been a strong and diverse demand for network capacity. The introduction of fine-granularity FlexE technology provides a new approach to addressing the diversification of Quality of Service (QoS) and the resource waste caused by large granularity (5 Gbps). However, the reduction in granularity leads to a significant increase in the number of slots, posing a serious challenge to deterministic latency assurance, especially in scenarios with dynamic fluctuations in service bandwidth. Sudden bandwidth variations can lead to service interruptions and fluctuations, resulting in uncontrolled network blocking rates. To address this issue, this paper proposes a traffic-driven proactive FlexE slot orchestration algorithm called PMFAN-GDSO. Based on this algorithm, bandwidth variations are calculated in advance based on the bandwidth change provided via the traffic prediction algorithm before service fluctuations occur. This avoids the time-consuming slot orchestration calculations and service abrupt changes. The real-world network datasets indicate that, based on our proposed algorithm, significant time savings of up to 46.8% are achieved compared to non-proactive prediction.

Future networks require a high degree of flexibility over wide areas to enable many services that require higher quality wireless networks such as remote control of cars and remote surgery. Therefore, the network technology must combine high capacity, low latency, and flexibility. To deal with these requirements, we developed Software-Defined Radio over Fiber (SD-RoF), which is an architecture that tightly couples light and radio at a low cost. SD-RoF offers the following two key features: elastic wireless service and elastic bidirectional passthrough. The elastic wireless service provides users with access to wireless services that they need at any time in any place. The elastic bidirectional passthrough connects two remotely located points via RoF through radio waves and enables allowing for bidirectional radio communication between devices at each location. In this study, we design and prototype implementation of SD-RoF, and conduct a basic evaluation of the implemented circuit and demonstration experiments on elastic bidirectional passthrough. Through demonstration experiments, we found the feasibility and the challenges of SD-RoF. In addition, the deployment of SD-RoF, application scenarios, and operational issues are discussed.

In the electric power communication network architecture, the Internet of Things business requirements of mutual perception and coordination of each link, and the traditional security protection structure based on boundary isolation, it is a difficult point to achieve a high degree of compatibility and coupling. Therefore, when PCE performs path calculation in the multi-domain FlexE network, it is necessary to consider the delay of the transmission path. The low-delay transmission of the service is ensured. This paper analyzes the network-slicing requirements of typical business scenarios in the power grid. In view of the hierarchical architecture of the power Internet of Things, this paper analyzes its requirements for 5G technology and network slicing, and the overall architecture of the integrated energy Internet. Finally, according to the current business needs, this paper proposes a power slicing scheme that meets the needs of the power grid's various business scenarios. On this basis, an end-to-end network architecture based on power slicing is designed. The results verify that the safe and efficient slicing strategy based on deep reinforcement learning has better performance than the traditional machine learning model, which can enhance the monitoring effect of the terminal network security of the power Internet of Things. It can also improve the terminal security of the power Internet of Things at this stage and can detect the potential risks of terminal security monitoring.
