Huawei’s Super Virtual Fabric (SVF) technology virtualizes multiple devices into one logical device to shield complex connections among devices and implement unified management and control of network devices.
Huawei CSS/CSS2 and iStack are horizontal virtualization technologies that virtualize multiple network devices at the same layer into one logical device, without changing the physical network topology, as shown in Figure 1-1. These virtualization technologies make ring network protocols in dual-homing networking obsolete and shorten failover time (trunk link convergence time instead of protocol convergence time). CSS/CSS2 and iStack simplify the network structure, which ultimately reduces network management costs.
