As network applications are increasingly offloaded to the programmable switches, program fitting problems come to the fore, which means effectively mapping the programming entities into the hardware resources. However, existing works fail to achieve resource-efficient deployment in an acceptable time. In this paper, we present Altair, a high-performance compiler system for program optimization and resource allocation. In addition to proactively optimizing the program by reducing logical redundancy, Altair designs a two-layer framework to generate the optimal mapping solutions with respect to all the hardware constraints while minimizing resource usage. We also propose a novel feedback mechanism between the two layers to make the best trade-offs among bottleneck resources and accelerate the solving process. Altair not only converts the network program into a functionally identical and compilable codes, but also uses up to 30% fewer hardware resources with at least 10X shorter execution time than state-of-the-art. © 2024, The Authors.

The rise of network function virtualization (NFV) technology makes the realization of network function change from hardware middleware to virtual network function (VNF). The existing methods allocate fixed resources to each VNF instance, but this resource allocation method will cause resource waste, which will affect the quality of service. The resource requirements prediction model solves the resource allocation problem by predicting the change of resource requirements. In this paper, deep learning is used to solve the regression prediction problem, and a VNF resource requirements prediction model based on convolutional neural network (CNN) and gated recurrent unit (GrU) is proposed. Compared with other single model and combined model, the experimental results show that the prediction error rate of the proposed model is reduced by 23.3%.

The current mimic adjudication model is centered on a single adjudicator, and the adjudication algorithm is relatively single and static, which cannot cope with today's complex and changeable network environment. First, a distributed adjudication model is proposed to decentralize the adjudicator, each sub-arbiter is different from the previous use of all executive results, but randomly selects the output of the executive as the input incentive. Secondly, based on this model, a consensus mechanism algorithm is proposed to iteratively normalize the local adjudication results of the sub-arbiters to achieve the global optimal adjudication result. The analysis of the simulation experiment results shows that the algorithm proposed in this paper is more accurate than the traditional adjudication algorithm when multiple executors are online. The algorithm can further reduce the risk of common-mode escape and improve the security of the mimic defense system. © 2022 ACM.

downlink MMSE Beamforming for dynamic Metasurface Antennas

Downlink MMSE Beamforming for Dynamic Metasurface Antennas

Electronic Information engineering and Computer Science (EIECS), 2021 International Conference on

作者： Zhiqiang Han Shuming Guo Shifei Wang School of Cyber Science and Engineering Zhengzhou University Zhengzhou China National Digital Switching System Engineering & Technological R&D Center Zhengzhou China

dynamic metasurface antenna (dMA) array is a new type of array structure with low complexity and low cost, which is emerging as a promising technique for next-generation wireless networks. In this paper, a downlink multi-user MISO system based on dMA arrays is investigated, and the mean square error (MSE) is chosen as a performance metric to characterize the transmission reliability. The beamforming performance of dMA arrays is investigated using the minimum mean square error (MMSE) criterion. For the multiuser scenario, the optimization problem minimizes MSE by jointly optimizing the transmit precoder and dMA weights while satisfying the transmit power constraint. Our numerical results show that the proposed MMSE scheme converges fast and performs close to full digital beamforming.

In the past decade, Fake Base Stations (FBS) have been consistently employed by criminals to target mobile users through spam text messages. despite the introduction of several techniques to mitigate this problem, spam messages remain a persistent and challenging issue in some countries, such as china, resulting in billions of dollars in annual economic losses. Therefore, this paper proposes an algorithm named BErT-GCN that combines large-scale pre-training models with Graph Convolutional Networks (GCN) for multi-class detection of fraudulent base station telecommunications scams in Chinese text messages. First, BErT (Bidirectional Encoder representation from Transformers) is used to encode the corpus and generate word embeddings. Subsequently, the generated word embeddings are fed into GCN for training. Finally, a Softmax layer is employed to perform multi-class detection on fraudulent base station telecommunications scams in Chinese text messages. Experimental results demonstrate that the proposed model achieves favorable performance on the FBS-SMS-dataset and exhibits outstanding performance in the domain of multi-class detection.

Website security detection is important for Internet security. Existing machine learning-based malicious UrL detection methods have a low accuracy and weak generalization ability. Thus, we proposed a new multi-feature fusion malicious website detection model BGresNet by integrating the advantages of Bidirectional Encoder representations from Transformers (BErT), Graph Convolutional Network (GCN), and residual neural network (resNet). The method integrates three features: Uniform resource Locator (UrL) creator, rule features, and website titles. First, we used BGresNet to process UrL characters and website titles separately, transforming them into vector representations. Then, these two vectors were fused with UrL rule vectors. Finally, we employed the softmax function to realize the detection of malicious websites. The experimental results showed that the proposed model exhibited significant superiority in detecting malicious websites, providing a new and effective method for malicious UrL detection in Internet security.

As a next-generation mobile communication technology, 5G's network functions—cloudification, virtualization, and other characteristics enable the network to overcome single-point resource constraints and be deployed flexibly. However, it also exposes more attack surface interfaces to malicious users, who can launch high-traffic ddoS attacks that can seriously affect the resilience of network services. The complexity and dynamics of the 5G system itself make it difficult to capture and measure its resilience. In order to address the aforementioned issues, in this paper, we use Petri Nets to model 5G network systems deployed based on virtualization and implement different resilient resource scheduling strategies to mitigate and assess the impact of attack threats on the overall system resilience. By comparing the resilience gains of different resource scheduling strategies in the face of anomalous ddoS attacks, it is effectively demonstrated that the adoption of appropriate resilient resource scheduling strategies is instructive in reducing the traffic loss caused by ddoS attacks. © 2024, The Authors.

Aiming at the shortcomings of existing user profile construction algorithms that do not fully utilize contextual structural information and multidimensional feature information., a user profile construction model based on the pre-training model NEZHA, deep Pyramidal Convolutional Neural Networks (dPCNN), Gated recurrent Unit (GrU), and attention mechanism is proposed, NCdGA. The method uses multiple channels to process the text, capturing different dimensions of information and constructing features to reduce the prediction bias that occurs when a single model captures a single feature. The experimental results show that the NCdGA model has better accuracy and effectiveness compared with other modeling methods.
