3. Unstoppable BYOD, Increasing Demand for Network Convergence
• Wireless : security, policy, and swarm traffic
• Network status: wired network + wireless network
• Challenges: management, expansion, experience
• Wireless terminal popularity: The global sales volume of smartphones
in 2013 exceeded 1 billion, a surge of 38% compared to 2012.
• BYOD popularity: 1.2 billion employees used mobile office in 2013,
accounting for 35% of the workforce.
• 802.11ac popularity: 802.11ac enables a rate of up to 1.3 Gbit/s, 3
times that of 802.11n.

4. Challenge 1: Separate and Complex Management
Overlay management of two separate networksOverlay management of two separate networks
• The wireless network is overlaid on the wired network.
Two networks run independently, with doubled
deployment and maintenance.
• Repetitive construction and investments, low return
on investment (ROI)
Massive terminals, various access modes, increased
management difficulty

6. Challenge 3: Inconsistent Experience for Wired and Wireless Users
Static configuration cannot adapt to
changes in wireless user positions.
Static configuration cannot adapt to
changes in wireless user positions.
• The static configuration mode based
on IP + Port results in scattered
configuration points.
• Different control modes should be
configured for external and internal
access to prevent information leak.
Traditional user policies cannot meet
BYOD requirements.
Traditional user policies cannot meet
BYOD requirements.
• Company and individual devices require
different security control policies.
• Mobile device types and quantity
increase sharply to cater for individual
preferences and unique experience
requirements.
Traditional QoS does not support
mobile multimedia services.

10. Huawei Native AC and Distributed AC Architecture
Native AC
Wired and wireless convergence, 802.11ac ready
Native AC advantages:
High-performance AC: 80 Gbit/s forwarding rate, 4 times that
of an independent AC, 1 Tbit/s for the entire device
Low costs: nearly 0 costs
Unified forwarding: wired and wireless traffic forwarding
through one card, real convergence
