作者： Lin Z. Zeng Z. y. y. ren y. Qiu X. Chen J. State Key.Laboratory.ofNetworking and Switching Technology Beijing University of Posts and Telecommunications Beijing 100876 China State Grid Jiangsu Electric Power Co. Ltd Nanjing 210008 China

For permanent faults (PF) in the power communication network (PCN), such as link interruptions, the timesensitive networking (TSN) relied on by.PCN, ty.ically.employ. spatial redundancy.fault-tolerance methods to keep service stability.and reliability. which often limits TSN scheduling performance in fault-free ideal states. So this paper proposes a graph attention residual network-based routing and fault-tolerant scheduling mechanism (GRFS) for data flow in PCN, which specifically.includes a communication sy.tem architecture for integrated terminals based on a cy.lic queuing and forwarding (CQF) model and fault recovery.method, which reduces the impact of faults by.simplified scheduling configurations of CQF and fault-tolerance of prioritizing the rerouting of faulty.time-sensitive (TS) flows; considering that PF leading to changes in network topology.is more appropriately.solved by.doing routing and time slot injection decisions hop-by.hop, and that reasonable network load can reduce the damage caused by.PF and reserve resources for the rerouting of faulty.TS flows, an optimization model for joint routing and scheduling is constructed with scheduling success rate as the objective, and with traffic latency.and network load as constraints; to catch changes in TSN topology.and traffic load, a D3QN algorithm based on a multi-head graph attention residual network (MGAR) is designed to solve the problem model, where the MGAR based encoder reconstructs theTSNstatus into feature embedding vectors, and a dueling network decoder performs decoding tasks on the reconstructed feature embedding vectors. Simulation results show that GRFS outperforms heuristic fault-tolerance algorithms and other benchmark schemes by.approximately.10%in routing and scheduling success rate in ideal states and 5% in rerouting and rescheduling success rate in fault states. © 2024 The Authors.

In this paper, we consider a susceptible-infective-susceptible(SIS) reaction-diffusion epidemic model with spontaneous infection and logistic source in a periodically.evolving domain. Using the iterative technique,the uniform boundedness of solution is established. In addition, the spatial-temporal risk index R0(ρ) depending on the domain evolution rate ρ(t) as well as its analy.ical properties are discussed. The monotonicity.of R0(ρ)with respect to the diffusion coefficients of the infected dI, the spontaneous infection rate η(ρ(t)y. and interval length L is investigated under appropriate conditions. Further, the existence and asy.ptotic behavior of periodic endemic equilibria are explored by.upper and lower solution method. Finally. some numerical simulations are presented to illustrate our analy.ical results. Our results provide valuable information for disease control and prevention.
