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.

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

Challenge 2: Specification Limitation, Difficult to Expand
Independent AC expansion difficulty.
Independent AC expansion difficulty.
• Capacity bottleneck on traditional ACs:
20 Gbit/s throughput, 1K APs.
• Independent space, power supply, and
cable deployment, difficult to expand
Explosive terminal growth overloads an AC.
Explosive terminal growth overloads an AC.
•Mobile terminals surge in popularity,
and one person may have several
terminals. The AC needs to manage
several thousands of APs.
Constantly-emerging services require frequent network upgrades.

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.
