ReclaimNet: Reclaim-Aware Network Protocols for Voluntary GPU Sharing on Campus
Wenyang Jia, Jingjing Wang, Xianneng Zou +1
University campuses host abundant but fragmented GPU resources whose voluntary sharing is blocked by a mismatch between revocable, autonomous ownership and migration mechanisms tha…
PolicyCache-SDN: Hierarchical Intra-Path Learning for Adaptive SDN Traffic Control
Wenyang Jia, Jingjing Wang, Ziwei Yan +3
Software defined networks offer global visibility, yet centralized control loops are too slow for transient congestion and bursty traffic dynamics. Existing learned traffic control…
OpenCLAW-Nexus: A Self-Reinforcing Trust Framework for Byzantine-Resilient Decentralized Federated Learning
Wenyang Jia, Qiankang Xu, Ziwei Yan +4
Decentralized Federated Learning (DFL) eliminates the central aggregator but introduces a severe 'trust gap': without a trusted coordinator, the system becomes vulnerable to Byzant…
SDN-SYN PoW: Adaptive Ingress-Aware Defense with Non-Interactive PoW Against Volumetric SYN Floods
Wenyang Jia, Jingjing Wang, Xianneng Zou +1
The stability of Internet services is persistently challenged by large volumetric TCP SYN floods, for which conventional defenses such as SYN Cookies preserve server state but stil…
BlockSDN: Towards a High-Performance Blockchain via Software-Defined Cross Networking optimization
Wenyang Jia, Jingjing Wang, Ziwei Yan +2
The scalability of blockchain systems is constrained by inefficient P2P broadcasting, as most existing optimizations focus only on the logical layer without considering physical ne…
BlockSDN-VC: A SDN-Based Virtual Coordinate-Enhanced Transaction Broadcast Framework for High-Performance Blockchains
Wenyang Jia, Jingjing Wang, Kai Lei
Modern blockchains need fast, reliable propagation to balance security and throughput. Virtual-coordinate methods speed dissemination but rely on slow iterative updates, leaving no…
