Data center scenario
Data center environments with well-defined requirements and clear network architectures are ideal for white-box switches. By deploying these switches, enterprises gain full control over their software and hardware operations, enabling the construction of cost-effective, highly reliable, high-performance, automated, and intelligent data center networks. In specific scenarios, the SR3700-CE acts as a Leaf node, providing 25GE port access and 100GE uplink capabilities to establish end-to-end 100GE connectivity. Furthermore, through integration with technologies like stacking, link aggregation, VxLAN, and EVPN, it creates a seamless Layer 2 VxLAN overlay network. This infrastructure ensures large-scale virtual machine migration and flexible deployment of user services.
5G bearer network scenario
5G bearer networks emphasize programmable, deterministic, customizable, and high-performance requirements for network protocols and functionalities, delivering dedicated line services with software/hardware slicing and QoS guarantees. White-box switches are transforming the traditional switch and router paradigm, achieving full compatibility across all scenarios from access bearer networks to next-generation backbone systems. In edge cloud/communication cloud networking, the SR3700-CE serves as a Leaf node, offering 25GE port access capability and 100GE uplink capacity to establish end-to-end 100GE connectivity solutions.
