This paper proposes a novel scheme to detect and localize the spy cameras based on AI algorithm based raw traffic analytics, named AI-aided Hidden Camera Locator (AHCL). In AHCL, the video streaming data are filtered via the SVM (support vector machine) algorithm to quickly monitor whole raw network traffic from a router to the networks first. Then, gathered traffic data are denoised by the Denoising Autoencoder (DAE) technique to improve the data quality of classification for localization, where a camera transmits video streaming. Based on the proof-of-concept implementation, the proposed scheme can achieve 99.5% positioning accuracy of camera detection with the Ensemble Neural Networks (NNs).

Future vehicles are expected to generate large amounts of data which may need to be off-loaded to a proximate server for processing. This led to the introduction of vehicular clouds (VC), which proposes that computing is done at nearby vehicles. However, as the vehicles may leave and join the VC randomly, the computing services of VC are time-varying, which may cause service interruptions. This work analytically evaluates the performance of the VCs under a service strategy that overcomes the interruptions caused by resource volatility. We use order statistics to derive the probability distribution of the number of vehicle arrivals to assign all the tasks of a job, the upper and lower bounds of mean job completion time, and the probability density function of the completion time of the longest task. Finally, we present the numerical results for the analysis and the simulation results to show the correctness of the analysis.

Volumetric Distributed Denial of Service attacks forcefully disrupt the availability of online services by congesting network links with arbitrary high-volume traffic. This brute force approach has collateral impact on the upstream network infrastructure, making early attack traffic removal a key objective. To reduce infrastructure load and maintain service availability, we introduce ReCEIF, a topology-independent mitigation strategy for early, rule-based ingress filtering leveraging deep reinforcement learning. ReCEIF utilizes hierarchical heavy hitters to monitor traffic distribution and detect subnets that are sending high-volume traffic. Deep reinforcement learning subsequently serves to refine hierarchical heavy hitters into effective filter rules that can be propagated upstream to discard traffic originating from attacking systems. Evaluating all filter rules requires only a single clock cycle when utilizing fast ternary content-addressable memory, which is commonly available in software defined networks. To outline the effectiveness of our approach, we conduct a comparative evaluation to reinforcement learning-based router throttling.

AS relationships are the basis for studying Internet security, route hijacking, route leakage, etc. To obtain more complete AS relationships, using machine learning (ML) models to learn the similarity between adjacent link groups and predict hidden links is a method that can obtain more complete AS relationships. The features selected by the ML model have a large impact on the accuracy of the prediction results, and we extract 10 ML features by combining the actual geographic location information of AS. After our optimization, the accuracy of the prediction model reaches 91.57%. In the classification of hidden link types, we oversample the small sample type data and optimize the classifier, and the classification accuracy of hidden link categories reaches 97.42%. The recall rate of p2c and c2p links improved by 24.29% and 7.17%, respectively. We found that the hidden links caused the change of network traffic transmission routes by the change of "Critical AS" in the AS network. AS 3549 has the highest number of effective paths, and the network traffic prefers to choose the AS with a lower hierarchy for forwarding.

A TCAM (Ternary Content-Addressable Memory) is a type of memory used in the flow tables of Software Defined Networking (SDN) nodes. Although these memories are very fast, their size is limited. This has an impact on the number of rules that can be installed, and an inefficient rule management can lead to a degradation of the network quality of service. In this work, an heuristic algorithm named Active Traffic First (ATF) is proposed to efficiently manage the content of the flow tables of the SDN nodes in order to maximize the Global Service Time (GST) of the active flows in the network. The idea behind ATF is adopted by deleting flows that are not being used in case a new flow aims to be served and there is no space available. Experimental results show that ATF outperforms other state-of-the-art solutions by improving GST and reducing re-installations.
TCAM(三元内容可寻址内存)是软件定义网络(SDN)节点流表中使用的一种内存。虽然这些存储器非常快，但它们的大小是有限的。这对可以安装的规则数量有影响，并且规则管理效率低下会导致网络服务质量的降低。本文提出一种主动流量优先(Active Traffic First, ATF)的启发式算法，对SDN节点流表内容进行有效管理，使网络中主动流的全局服务时间(Global Service Time, GST)最大化。ATF背后的思想是通过删除未被使用的流来实现的，以防新流的目标是服务，并且没有可用的空间。实验结果表明，通过提高GST和减少重新安装，ATF优于其他最先进的解决方案。

Low latency is critical to applications such as control of unmanned aerial vehicles. Such latency-sensitive services can be hosted closer to the user at the fog layer which can reduce overall latency through the reduction of transmission time and network congestion. To keep the latency low for mobile users connected to services deployed at the fog, these services need to be constantly migrated to follow the users. Unlike the cloud nodes, fog nodes are less reliable and are therefore subject to higher failure rate. In this paper, we propose an enhancement to the post-copy live migration algorithm to make it robust against failure. Simulation results show that robust migration reduces total migration time between 10-26% and downtime between 2-23% compared to non-robust migration. Furthermore, when the bandwidth to the backup node is lower, robust migration provides further improvement in both metrics.

In the last decade, numerous Industrial IoT systems have been deployed. Attack vectors and security solutions for these are an active area of research. However, to the best of our knowledge, only very limited insight in the applicability and real-world comparability of attacks exists. To overcome this widespread problem, we have developed and realized an approach to collect attack traces at a larger scale. An easily deployable system integrates well into existing networks and enables the investigation of attacks on unmodified commercial devices.

Service Function Chaining (SFC) enables dynamic steering of traffic through a set of service functions based on classification of packets, allowing network operators fine-grained and flexible control of packet flows. New paradigms like Zero Trust (ZT) pose additional requirements to the security of network architectures. This includes client authentication, confidentiality, and integrity throughout the whole network, while also being able to perform operations on the unencrypted payload of packets. However, these requirements are only partially addressed in existing SFC literature. Therefore, we first present a comprehensive analysis of the security requirements for SFC architectures. Based on this analysis, we propose a concept towards the fulfillment of the requirements while maintaining the flexibility of SFC. In addition, we provide and evaluate a proof of concept implementation, and discuss the implications of the design choices.
SFC (Service Function chains)是一种基于报文分类，通过一组业务功能对流量进行动态引导的技术，使网络运营商能够对报文流进行细粒度、灵活的控制。像零信任(ZT)这样的新范式对网络架构的安全性提出了额外的要求。这包括整个网络中的客户端身份验证、机密性和完整性，同时还能够对未加密的数据包有效负载执行操作。然而，这些要求在现有的SFC文献中只得到部分解决。因此，我们首先对SFC架构的安全需求进行了全面的分析。基于这一分析，我们提出了一个在保持SFC灵活性的同时满足需求的概念。此外，我们提供并评估了概念实现的证明，并讨论了设计选择的影响。

This paper presents an adaptive self-learning classifier-based clustering algorithm called AlcFier, to support scalability, enhance the stability of the network topology, and provide efficient routing. We incorporate mobility and channel characteristics (i.e., orientation, adjacency, link availability, queue occupancy, and signal-to-noise ratio) into the clustering approach as a channel-aware metric to provide a new direction to the taxonomy of the approaches employed to handle cluster head election, cluster affiliation, and cluster administration challenges. Experimental results show that AlcFier performs efficiently, improves cluster stability, reduces transmission delays, and improves throughput compared with the state-of-the-art routing protocols.

In this paper, we deal with a wireless sensor network (WSN) infrastructure management problem where a provider wants to partition a network into a given number of node-disjoint subgraphs (called slices) for running different user applications. Nodes in the given infrastructure use energy harvesting for prolonged service time. The nodes manage fluctuations in their stored energy by adjusting their transmission range. We assume that each node is assigned an importance weight, and model the overall network using a probabilistic graph. In this context, we formalize a problem, denoted k-WBS-RU (for k weighted balanced slices with range uncertainty), to partition the network into k slices subject to some connectivity and operation constraints. We devise a solution to the problem, and present numerical results on the quality of the obtained slices. We also discuss an application of the proposed framework and solution when the assigned weights are derived from an area coverage application.
