Challenges to Network Security Single-Point Static Defense VS Multipoint Dynamic Unknown Threats
BYOD
Blurred Defense Border
Diverse Attack Methods
From Known to Unknown Threats
Challenges to Network O&M Personnel Unknown Status, Manual Management
The network is unaware of user
experience
Abundant devices, complex configurations, silo’ed management
1. A huge number of access devices
2. Static configuration
3. No unified management for wired and wireless networks
What Should a Next-Generation Network Do?
1. Shift the focus from technology, device, and connectivity
to service and user experience
2. Shift from single-point management to complete network
management
3. Shift from best effort to real-time quality detection on the
network
4. Shift from static configuration to dynamic auto deployment
5. Shift from hardware-defined to software-defined
