VxLAN技术在天地一体化网络中的应用研究
Research on the application of VxLAN technology in space-integrated-ground networks
摘要
Abstract
Addressing the requirements for cross-regional interconnection,multi-vendor device coexistence,and service isolation within the ground internet bearer layer of integrated space-terrestrial network systems,this paper investigates the challenges of adapting VxLAN heterogeneous networking within the future internet technology infrastructure(FITI).Leveraging the FITI nodes in Xining,Lanzhou,and Nanchang,an experimental environment featuring a VxLAN Overlay built upon an IPv6 bearer network was constructed to conduct tests regarding tunnel establishment,local and remote MAC learning,and real source address validation across devices from multiple vendors—including Huawei,H3C,and Ruijie.This study positions itself as a pre-validation for the ground internet bearer layer of integrated space-terrestrial network systems,it focuses on analyzing the differences among multi-vendor devices regarding VLAN/VNI mapping,tunnel or-ganization methods,MAC learning mechanisms,and security policy enforcement,and synthesizes these findings across four dimensions:control plane compatibility,data plane encapsulation consistency,operational observability,and scenario adaptability.Test results demon-strate that VxLAN can provide foundational Overlay support for cross-regional service isolation and heterogeneous device interconnec-tion,but its actual networking performance is significantly influenced by specific device implementation approaches and inter-device coor-dination capabilities.These findings serve as a valuable reference for technology selection,heterogeneous interconnection design,and fu-ture research into collaborative mechanisms for the ground internet bearer layer of integrated space-terrestrial network systems.关键词
