scenario overview scenario overview this solution is targeted at small and medium sized parks and adopts the advanced spine leaf full three layer network architecture it realizes the automated deployment, centralized management and intelligent operation and maintenance of the network through a cloud based park controller the solution adopts key technologies such as distributed gateways and dhcp high availability, providing a high performance and highly reliable network foundation for the access of small and medium sized terminals centrally intelligent management core the controller automatically translates business intents into device configurations through a graphical interface and deploys them accurately, completely eliminating the traditional tedious process of configuring devices one by one via command line interface it offers full lifecycle management, including device onboarding, monitoring, and diagnostics, enabling network automation and high reliability elastic and reliable network backbone simple and flat, efficient forwarding adopting a spine leaf two layer architecture, the structure is simple and the path is optimized all leaf devices are fully interconnected with dual spine, achieving efficient and low latency data forwarding between any two points distributed gateway, traffic optimization business gateways are distributed and deployed on leaf switches at each access layer cross subnet communication traffic between terminals can be forwarded nearby at the access layer without detour to the core, effectively reducing transmission delay, enhancing service experience, and simultaneously alleviating the load pressure on the spine layer stable and reliable access and service leaf distributed gateway serving wired and wireless terminals within the park the gateway is lowered to the access leaf, achieving isolation of the broadcast domain and convergence of the fault domain while providing flexible subnet planning, it ensures the stability and forwarding efficiency of the access layer high availability of key services deploy key network services such as dhcp server on two spine devices and automatically build dhcp failover relationships this design ensures the continuous availability of the address allocation service even if a single spine device fails, seamless service switching can be achieved, guaranteeing the continuity of terminal business scheme design scheme design the small and medium sized campus network adopts the spine leaf networking architecture, based on the classic full three layer routing network of the cloud based campus ebgp is automatically formed between spine and leaf through the controller, and distributed gateways are deployed on leaf devices access zone leaf1 and leaf2 serve as distributed gateways leaf1 is responsible for connecting aps and wireless terminals, while leaf2 is responsible for connecting wired terminals dhcp deployment dhcp servers are deployed on both spine devices and are automatically configured as a dhcp failover pair via the controller, ensuring high availability of address services controller deployment the controller is cloud based and enables centralized policy deployment, configuration management, and status monitoring for all network devices through a graphical interface, significantly improving operational efficiency foundation link
