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.

•Mobile terminals surge in popularity,

and one person may have several

terminals. The AC needs to manage

several thousands of APs.

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.
