SecureNT: Smart Topology Obfuscation for Privacy-Aware Network Monitoring
Chengze Du,
Jibin Shi,
Hui Xu,
Guangzhen Yao
International Conference on Intelligent Computing   (ICIC 2025)
[📁Code]
[📜Paper]
[😀arXiv]   Oral

Identification of Path Congestion Status from End-to-End Measurements Using Deep Spatial-Temporal Learning
Chengze Du,
Zhiwei Yu, Xiangyu Wang
Computer Communications
[📁Code]
[📜Paper]
[😀arXiv]
This work introduces the concept of Additive Congestion Status to address these challenges effectively. Using a framework that combines Adversarial Autoencoders (AAE) with Long Short-Term Memory (LSTM) networks, this approach robustly categorizes and quantifies the Additive Congestion Status.
