“…With the increasingly close integration of artificial intelligence technology and networks, the operation and production of networks in the future should be fully digitalized, automated and intelligent.At present, fault locating of cross-professional network mainly relies on operation and maintenance staff of each professional network to analyze and dispatch orders, resulting in long trouble clearing time and repeated orders.In order to save manual work, with the help of automation and artificial intelligent technologies, a cross-professional network intelligent operation and maintenance system was developed and applied in real network.The associated topology information of IPRAN and OTN, along with the real-time IPRAN and OTN alarm data were analyzed, the root cause alarm was located accurately, the fault location was determined, and dispatch order was achieved automatically.A automatic cross-professional fault diagnosis capability was built by the system, which reduced the fault locating time from traditional two minutes to tens of milliseconds, therefore, the manual work was reduced by more than 90%, and 95% fault types of the existing network could be covered.…”

EBS-based efficient and secure group key management in wireless sensor networks by WANG Wei1, ZHAO Wen-hong2, LI Feng-hua3.4, MA Jian-feng3

“…To achieve the secure group communication in wireless sensor networks（WSN）, a EBS-based group key management scheme was presented.First, the network topology was simplified by combining the chain-clusters and the star-clusters.Next, to prevent the adversary uncover all the administrative keys by a few colluding sensors, the number of sensors needed to capture WSN was increased.Then, the sensors of key combinations distribution were sorted through a coloring algorithm.Based on all these operations, the presented scheme distributed the administrative keys based on the hamming distance and EBS.Furthermore, the approaches handling the join event and leave event were described.Two experiments were performed to study the potential for collusions and the influence of size of compromised nodes on the effectiveness against collusions.Simulation results demonstrate that the presented scheme boosts the WSN’ resilience to attacks.The performance evaluation on join event and leave event shows that the number of key-updating messages and storage of sensors in the proposed scheme are fewer than those of SHELL.…”

Global cyclic queuing and forwarding mechanism for large-scale deterministic networks by Yijun MO, Zihan YANG, Huiyu LIU, Tianliu HE

“…Delay and jitter sensitive industrial control and remote driving application-driven network by best-effort to deterministic service.To meet the deterministic application of delay and jitter demands, industry and academia have conducted detailed research on stream filtering shaping and queue forwarding control, implementing microsecond delay and microsecond jitter of light load steady in small-scale ethernet environment.However, the study seldom considers the effects of long-distance topology change, transmission delay fluctuations and short-time traffic overloads, challenging to meet deterministic requirements under large-scale backbone networks.For this challenge, based on cyclic queuing and forwarding, considers source-destination path properties and deterministic traffic intensity, the global cyclic queuing and forwarding three-queue was proposed.The deterministic network simulation system was based on OMNeT++.Experiments compare queue forwarding control mechanisms such as CQF, CQF-three and GCQF-three.Results show that GCQF-three can timely adjust the gatecontrol and queueing priority according to the deterministic traffic state, achieves the best in delay, jitter and network utilization.…”

Coding-aware secure routing for multi-hop wireless networks by Xian GUO, Tao FENG, Zhan-ting YUAN

“…To address security issues of DCAR in“coding+routing”discovery,a new security destination was proposed and a distributed coding-aware secure routing(DCASR)was designed.DCASR guarantees discovery of correct coding opportunity and establishment of trusted routes by using cryptography.To analyze the properties of DCASR,LS2(logic of security systems)was extended,and a new logic LS2-RP(LS2 for routing protocol)was proposed.In LS2-RP,the concepts of location and neighboring location of thread were introduced.The dynamic topology of multi-hop wireless networks was described by the set of neighbors for thread.The broadcast rule of neighboring location threads modeled the feature of wireless broadcast communication.Finally,DCASR was described by programming language of LS2-RP and security properties were defined by predicates and modal formulas of LS2-RP.Security of DCASR was analyzed by using the proof system of LS2-RP.DCASR can satisfy our secure destination.…”

Reliability and cost efficiency analysis for deep space habitat network based on Nash bargaining solution by Zi-jing CHENG, Jun-nan ZHAO, Yu-wen CUI, Le-yi SHI

“…Focusing on the deep space habitat network requirements of high reliability and expensive links,two impact factors to the network performance were regarded as a multi-objective optimization problem,which were network reliability and cost efficiency model,and the relations between the two factors were formalized.Thereafter,the Nash model of cooperative game was used to make a fairness compromise to the network reliability and cost efficiency,and the Nash bargaining solution set was acquired through the Matlab platform with CVX.Further,through changing the threat value dynamically and performing the repeated game,the Pareto optimal solution could be obtained which can ensure the fairness of reliability and cost efficiency simultaneously.Finally,the Nash bargaining method was applied to a typical deep space habitat network topology,and described in detail how to set up the link numbers and link capacity in order to reduce the cost when the network traffic and the link capacity were given.The proposed work is important for the deployment and optimization of the deep space habitat network.…”
