Ruckus Messages & FAQ Page 3 | 14

Q: What do you mean when you say Brocade wants the network to be a platform for innovation?

• As companies move to digitize their businesses they need an underlying network infrastructure that allows them to innovate quickly for their employees and customers. We believe the network must become a platform for developing, delivering, and securing these applications. This is best achieved with the move to New IP network architectures that are software-centric, open, and agile. The wireless edge is a critical component of these new architectures for all types of customers.

• Best-in-class: The combined company will be able to deliver solutions that are designed for today’s requirement for open, multi-vendor networks with robust partner ecosystems to support each customer’s unique needs.

• Partner of choice: The ability to partner with virtually every vendor of server and storage solutions, as well as leaders in software networking and virtualization, means our customers don’t have to settle for less-than-optimal infrastructure solutions from slower-moving companies that have a vested interest in locking their customers into proprietary architectures.

• History has proven that focused companies innovate more quickly, are more agile, and deliver better value to their customers.

Q: Why does this deal make sense now?

• Expected to strengthen both companies’ ability to compete for wired/wireless opportunities globally.

• Expected to accelerate success in key markets such as Service Provider, government, education, healthcare and large enterprises.

• The industry is on the cusp of a big upgrade cycle to 802.11ac Wi-Fi. The combination better positions both companies for that significant opportunity.

Q: How does Ruckus fit into Brocade’s strategy and support the New IP?

• The New IP is a network revolution that is changing the rules of how network infrastructure is designed, provisioned and deployed. New IP networks are essential as companies and other organizations digitize their operations and service delivery and move to third platform environments to support the cloud, Internet of Things, mobile services and big data.

• New services and operational models require a high-speed, consistent access network. Wireless technologies are crucial to support New IP infrastructures at the network edge.
