The Datacenter Network Challenge:
Not Optimized for Today‟s Traffic
• Traffic patterns in the datacenter have changed due to
new application designs AND virtualization
– Explosion in VMs
• The network has not changed
• Current network has:
– Multiple Tiers and Uses
– Limitations of Spanning Tree: Slow to reconfigure, adds
multiple layers
• Multiple networks in the datacenter add costs and is
inflexible

Campus LAN: Refresh Drivers
• More bandwidth, scalability in network infrastructure
– Growth of enterprise data and multi-media traffic
– 100Mb to 1GbE, 1GbE to 10gbE Upgrade
– Only 31% IT managers expect network to meet performance requirements in
next 12 months*
• Need for PoE and PoE+
– Driven largely by VoIP and 802.11n WLAN Upgrades
• Move to “Flatter” Networks
– Take distribution layer out where possible
• Introduce NAC-like capabilities
• Energy efficiency
![Page 21: The Connected Enterprise: An Overview of Today‟s Key ......–Enterprise video collaboration (training, marketing, events, etc.) IT will react to this video explosion: –Throw more](https://reader033.vdocuments.mx/reader033/viewer/2022042415/5f2faf698e373212537e551c/html5/thumbnails/21.jpg)
Remote, Branch Office Needs
• Desire for unified communications and collaboration (UCC)
applications in an affordable footprint
• Improve customer walk-in experience (branch)
• Increase employee productivity and revenue per customer
• Access experts anywhere to increase customer transaction close
rate
• Flexible architecture to enable local adaptability through local
install or scale through delivery from a centralized location
• Leverage UCC apps to maximize customer interactions,
satisfaction, revenue
• Reduce cost of doing business

Remote Branch Network
• Strategic opportunity for IT to add business value
• Need for “many-to-many” even greater with real-time access needs, exponential
transaction growth
• Traffic partitioning, shaping, bandwidth controls, content filtering
• Delivering network as a cloud-based service?

Smart Mobile Devices: Diversity, Explosion
• In 2011, 2x „smart‟ mobile devices
ship than laptops
• Drive an explosion in social
interactions, mobile transactions
and digital content creation
• Server and network infrastructure
needs to support resulting edge,
application and database workloads
• Collaborative, Web and security
infrastructure also important
![Page 25: The Connected Enterprise: An Overview of Today‟s Key ......–Enterprise video collaboration (training, marketing, events, etc.) IT will react to this video explosion: –Throw more](https://reader033.vdocuments.mx/reader033/viewer/2022042415/5f2faf698e373212537e551c/html5/thumbnails/25.jpg)
Emerging WLAN Architectures
• Variants of centrally managed wireless
LANs continue to proliferate:
– Direct forwarding, controller-based
– Centralized vs. distributed control,
controller-less
• Unified- wired and wireless
• The differentiation still mostly around how
to handle the control and the management
plane
• Seamless WiFi – cellular handoffs,
improved in-building coverage using
DAS/other solutions
• Branch of one/teleworker
– Provisioning, secure access

Wireless At The Network Edge:
Will it Remain An Overlay Network?
26% of all APs
95%of all APs
• Increased diversity in 802.11n
deployments
- Single radio to multi-radio, multi-
spatial streams
• Tablets, smartphones drive demand
• Architectures become relevant
• Wireless best practices migrate
over to unified network
