基于全光网络技术的高校校园网建设研究OA

Traditional campus networks commonly suffer from pronounced bandwidth bottlenecks,uneven cov-erage distribution,prominent safety hazards in telecommunication closets,and insufficient multi-service carry-ing capacity.Leveraging advantages such as long transmission distances,high bandwidth capacity,and strong anti-interference capabilities,optical fiber networks have become the mainstream choice for upgrading universi-ty campuses.By systematically comparing passive optical networks(PON)and ethernet all-optical networks-particularly regarding architectural modes,bandwidth characteristics,and operation and maintenance(O&M)complexity,a hybrid networking architecture tailored to specific scenarios was proposed.Taking into account the characteristics of university dormitory areas(high user density,relatively balanced traffic models,and con-centrated O&M pressure)versus teaching and office areas(which host smart classrooms,research services,and administrative operations,with stringent requirements for bandwidth determinism,latency,and service isola-tion),the proposed solution adopts"PON for dormitories+ethernet all-optical for teaching & office areas".This architecture efficiently supports the high-speed information flow required for core university functions,in-cluding administration,teaching,research,management,and services.
