Scene Selection

to simplify the configuration of common typical network setups, the controller has four built in scenarios small/mid scale campus, large/mid scale campus, traditional l2 network, and open cloud connect administrators can select any network setup according to the network scale to complete topology planning after entering the specific venue, the administrator clicks the \[configuration] \[design topology] button to select the specific scenario to be used small/mid scale campus small/mid scale campus small/mid scale campus adopt the advanced spine leaf full three layer network architecture and achieve automated network deployment, centralized management and intelligent operation and maintenance through cloud based park controllers 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 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 large/mid scale campus large/mid scale campus large/mid scale campus adopt a spine aggregation leaf full three layer network architecture the network is divided into a default access zone and a server zone, utilizing key technologies such as distributed gateways and mc lag to provide high performance and highly reliable network connectivity for large scale terminal access and high availability server clusters elastic and reliable network backbone ultimate scalability horizontal expansion at the aggregation layer supports the integration of large scale leaf switches, effortlessly accommodating future network growth flexible gateway deployment distributed service gateways can be deployed at the leaf layer, confining service traffic to the access layer this significantly enhances forwarding efficiency and network reliability while effectively reducing the burden on upper layer devices scenario optimized access technologies leaf distributed gateways serve wired and wireless terminals in the default access zone by sink gateways to the access leaf, cross subnet communication for terminals no longer needs to traverse the core layer, significantly reducing latency and enabling fault domain isolation leaf mc lag provides high availability layer 2 access for the server zone two leaf switches are virtualized into a single logical device via mc lag to connect with servers, achieving link level and device level load balancing and seamless failover this eliminates loops while ensuring uninterrupted continuity for critical business operations traditional l2 network traditional l2 network the traditional layer 2 network solution is based on the classic spine leaf architecture this solution adheres to the design principles of network stratification and separation of responsibilities, providing a stable, efficient, and easily maintainable standardised foundational network platform for environments such as campuses and data centres it combines a reliable architecture proven over decades with modern centralised management capabilities, ensuring non blocking, low latency forwarding of service traffic within layer 2 domains while achieving centralised and highly available layer 3 gateway functionality adopting the classic spine leaf networking, the leaf layer serves as a pure layer 2 device, focusing on high speed access and local switching the spine layer, as a three layer gateway and policy execution point, realizes centralized and efficient routing of cross subnet traffic this clear division of responsibilities makes network behavior completely predictable, providing a stable connection with constant low latency and high bandwidth for upper layer services open cloud connect open cloud connect the open cloud connection scenario has fully opened up the classic layer 2 switching and layer 3 routing functions in the single device form, supporting users to customize network functions according to actual business needs supports atomic level on demand business configuration for individual devices this process is independent of the network topology, achieving high flexibility and scenario adaptability, and can precisely meet various business requirements ranging from standardized deployment to highly customized in addition, the controller supports the direct deployment of a dhcp server on a single access switch, further enhancing the autonomy and deployment flexibility of network services, and effectively meeting users' address management needs in diverse network environments
