“…The influence of VMs state transitions on the timely reliability is not modeled. (2) End-to-end delay models of a network are often verified by Monte Carlo discrete event simulation using Java Modeling Tools (JMS) [ 24 ], OPNET [ 18 ], OMNeT++, etc. Timely reliability has been analyzed [ 18 , 32 ], but the influence of VM state transitions on the timely reliability is still not modeled.…”

“…However, due to the mathematical complexity, the formulation of the networked queueing model is infeasible when the queueing nodes are more than three. Therefore, approximation methods such as simulation [ 18 , 59 ] and the upper bound method [ 60 ] are widely applied. Researchers also studied the end-to-end delay of queueing networks based on the departure process approximation.…”

“…The ability of an edge computing network to transmit and process data within the given time can be measured by timely reliability [ 15 , 16 , 17 , 18 ]. To analyze whether the VMs in the edge server and the whole network satisfy the time requirements of a task, we define the VM timely reliability (VTR) and the end-to-end timely reliability (ETR), respectively, and propose analysis methods.…”

“…The end-to-end delay in the computer network consists of four types of delay [ 19 ], that is, processing delay, transmission delay, propagation delay, and queueing delay. Since queueing delay is the main random variable of the four components of end-to-end delay [ 18 ], we only consider processing delay and queueing delay of the edge server in this paper. From the perspective of edge computing, an edge server can be treated as a multi-server queue with unreliable servers, where the VMs are servers and the tasks are customers.…”

For the edge computing network, whether the end-to-end delay satisfies the delay constraint of the task is critical, especially for delay-sensitive tasks. Virtual machine (VM) migration improves the robustness of the network, whereas it also causes service downtime and increases the end-to-end delay. To study the influence of failure, migration, and recovery of VMs, we define three states for the VMs in an edge server and build a continuous-time Markov chain (CTMC). Then, we develop a matrix-geometric method and a first passage time method to obtain the VMs timely reliability (VTR) and the end-to-end timely reliability (ETR). The numerical results are verified by simulation based on OMNeT++. Results show that VTR is a monotonic function of the migration rate and the number of VMs. However, in some cases, the increase in task VMs (TVMs) may conversely decrease VTR, since more TVMs also brings about more failures in a given time. Moreover, we find that there is a trade-off between TVMs and backup VMs (BVMs) when the total number of VMs is limited. Our findings may shed light on understanding the impact of VM migration on end-to-end delay and designing a more reliable edge computing network for delay-sensitive applications.

e Internet protocol television brought seamless potential that has revolutionized the media and telecommunication industries by providing a platform for transmitting digitized television services. However, zapping delay is a critical factor that affects the quality of experience in the Internet protocol television. is problem is intrinsically caused by command processing time, network delay, jitter, buffer delay, and video decoding delay. e overarching objective of this paper is to use a hybrid delivery method that agglutinates multicast-and unicast-enabled services over a converged network to minimize zapping delay to the bare minimum. e hybrid method will deliver Internet protocol television channels to subscribers using the unicast stream coupled with differentiated service quality of experience when zapping delay is greater than 0.43 s. is aids a faster transmission by sending a join message to the multicast stream at the service provider zone to acquire the requested channel. e hybrid method reported in this paper is benchmarked with the state-of-the-art multicast stream and unicast stream methods. Results show that the hybrid method has an excellent performance by lowering point-to-point queuing delay, end-to-end packet delay, and packet variation and increasing throughput rate.

With the increasing adoption of industrial Ethernet in train communication network (TCN), the limitations of insufficient reliability and incompatibility between different Ethernet technologies have become increasingly apparent. To address these challenges, time‐sensitive networking (TSN) has emerged as a solution, enabling multi‐network convergence and enhancing data transmission determinism and reliability through techniques such as frame replication and elimination for reliability (FRER). However, the utilization of these policies will adversely affect schedulability due to increased network load. To address the issue of link failures in TCN topologies, a routing policy based on faulty link diagnosis is proposed. The proposed policy utilizes an improved max‐min ant system (IMMAS) for diagnosing and resolving faulty links. Furthermore, a routing optimization algorithm is introduced to enhance transmission reliability by planning alternative paths for traffic. To evaluate the performance of the proposed routing algorithm, multiple sets of test cases are conducted separately under different failure scenarios to compare them with other routing policies. The results demonstrate the superior reliability of the proposed routing policy over alternative approaches. Additionally, the traffic utilizing the proposed routing policy show improved schedulability following integer linear programming (ILP) scheduling. © 2024 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
