By using optical Ethernet interface for stacking, the stacking distance can be up to 80km and even more, it helps customer to get rid of distance restriction while designing a reliable VSC system.  
    • Reliability: Independent out-band management makes the control plane and forwarding plane separated. Through real-time control information hot-standby technology, the VSC system can achieve seamless switchover when failure happens. 
    • Saving investments: No need special stacking line card, the normal line card can be used for VSC connecting. When some interfaces are used for VSC, the other interfaces on this line card can also be used for traffic forwarding. No interfaces are wasted and that helps customer to save investments.  
    • Flexibility: Master and slave in VSC2.0 works in 1+N redundancy mode, MAD (Multi-active Detect) technology is used to detect and avoid dual master in VSC system when failure happens. Together with real-time hot-standby and seamless switchover it brings customer a more flexible VSC network.
    • VSC3.0: using the 5960 device as the remote Line Interface Card for 9900(-S) to realize the vertical virtualization.
  • VLD (Virtual Logical Device) Technology

    • VLD (Virtual Logical Device) technology can deliver an industry-leading virtualization capability that makes one switch to be virtualized into as many as sixteen logical switches. This 1:16 ratio enables one core switch to manage services for an enterprise’s multiple service areas such as production, office, and DMZ, or for multiple tenants.
    • VLD technology divides one network into separate logical areas for service isolation. The failure of one virtual switch does not affect other virtual switches, enhancing network security.
    • VLD technology improves the use efficiency of physical devices by implementing on-demand resource allocation and saves space in data center equipment room. This ensures network scalability, reduces investment in devices and reduces the cost of device maintenance.
    • VLD technology can be deployed with the VSC, which deliver the switch resource virtualization pool.
