Analysis and modeling of Internet backbone traffic with 5G/B5G by Yuan YANG, Mingwei XU, Hao CHEN

“…The effects that the 5th generation mobile network (5G) bring to Internet backbone were investigated qualitatively and quantitatively.First,the challenges that the characteristics of 5G,i.e.ultra-high data rate,ultra-low latency,and ultra-large number of connections,introduce to Internet backbone in terms of traffic,latency,and security were analyzed.Second,a model was proposed to capture the characteristics of 5G users and Internet traffic with the coordination of 5G,edge computing,and cloud computing.Then,numerical simulations were used to evaluate the model.The QoS requirements that Internet backbone faces under different extent of 5G deployment were evaluated.According to the study,increment of backbone traffic,increment of the ratio of propagation delay,and movement of bandwidth bottleneck are predicted after 5G/B5G deployment.…”

Intelligent interference management in 5G wireless networks by Jiandong LI, Lei LIU, Min SHENG, UChao X

“…As one of the key technologies in 5G networks，ultra-dense wireless network is utilized to approach the future 1 000 ultra-high traffic volume.Nevertheless，the dense deployment of network nodes would result in severe interference，and thus interference management was proposed as the big principle behind 5G ultra-dense wireless networks research.Firstly，the interference management schemes were classifed from two aspects：avoidance and utilization.Then，an intelligent interference management architecture was proposed to accommodate the development trend of future wireless networks in terms of intelligence and heterogeneity in order to realize the dynamic tightly coupled interference management of wireless network environment and interference management.Taking the intrinsic relationship between interference management and resource management into consideration，three cutting-edge interference management schemes were introduced，which could significantly improve the network resource utilization and the network capacity.…”

Network architecture and key technologies of intelligent optical networks driven by data and model by Zhiqun GU, Jiawei ZHANG, Yuefeng JI, Hao YU, Taleb Tarik

“…With the expanding scale of the networks and the emerging applications of ultra-massive connection, ultra-high bandwidth and ultra-low delay, higher requirements are proposed for the utilization of optical transmission network resources and network differentiated services, which makes the network and configuration mode driven by the traditional approaches face challenges.Based on the idea of data and model collaborative driving, the intelligent optical network technologies of three-layerthree-cycle architecture and three functions were proposed, and the implementation technology was studied.The performance of the proposed algorithms was evaluated based on the designed intelligent transmission network platform.The validation results show that the transmission performance of intelligent optical network driven by collaborative data and model has been effectively improved, which provides theoretical and technical support for the realization of network intelligence.…”
