Abstract:	As a critical infrastructure supporting high-performance cloud computing services, the scale of data center networks (DCN) continues to expand rapidly. However, traditional wired data centers suffer from deployment difficulties as well as cabling complexity. To address these challenges, we propose a novel hybrid data center network architecture, VBNet, which effectively integrates Visible Light Communication (VLC) technology with BCube structure. First, VBNet requires no modifications to the existing infrastructure and only involves installing VLC wireless transceivers on the sides and tops of racks. Second, we design a hybrid unicast routing algorithm based on the VBNet structure to reduce the number of hops required for inter-rack routing. Additionally, to ensure reliable data transmission in the presence of signal obstructions, we developed the Obstacle Avoidance Adaptive Routing (OAAR) algorithm. Comprehensive evaluations demonstrate that VBNet provides higher connectivity, shorter average path lengths, and significantly enhanced performance compared to the original wired structure.
