Video and More Video:
Impact on the Enterprise Network
Video and related applications proliferate:
– Video-conferencing no longer niche
– Video surveillance and other streaming apps
– Enterprise video collaboration (training, marketing,
events, etc.)
IT will react to this video explosion:
– Throw more bandwidth at the problem
• Vendors will roll out 40/100G sooner
– Improved compression technologies (H.264 SVC
and H.264 High Profile – uses 50% less b/w)
– Deploy intelligent networks

The New Enterprise Network
The New Enterprise Network is an efficient, intelligent, converged fabric that extends from the edge to the data center
The New Enterprise Network is also VIRTUAL

Virtual Services Fabric
• Extends from the edge to the Datacenter, Core
• Provides integrity of identity from the user to the datacenter
• Adds Intelligence to your network infrastructure
– Orchestration of Data, Management and Control Plane
Home Offices, Mobile Users
Branch Offices
Regional Offices
Virtual Network Services – Examples
Visibility & Reporting + Visibility/Monitoring, Reporting on events based on severity
Identity Management + Authenticate user and provide appropriate application access
Device Intelligence + Auto-discovery of device on wired or wireless network
One-Click Provisioning + Automated provisioning and configuration of network devices
Content Filtering + Enforcing policy based on content (or user, location, device, etc)
Traffic Shaping + Bandwidth limiting, traffic optimization, etc.
Diagnostics + Cloud-based diagnostic tools, auto-remediation
Virtualization and the Network:
Best Practices Emerge
• Network managers evaluating
best practices
– Default build for IT
– Simpler, efficient provisioning,
configuration
– Optimized Traffic Separation,
Shaping
– Automation
– Regulatory, Compliance
• Built-in Intelligence based on user, device, application
and location
Adding Network Intelligence
Management
Control
Data
Centralized
Hybrid?
Distributed
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
Enterprise Data Center
High availability—always on
Pay as you grow
Ultra high capacity
Predictable performance under load
End-to-end solution
Some degree of automation
Drivers Requirements
Reduce TCO
Find means to simplifying the network
– Cost effective aggregation
– Investment protection for 10 GbE
Offer best in class services, need to control costs but deliver high availability
Quickly scale to meet demand, roll out new services
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
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
• Revenge of the consumer
– 2011 brings a different level of
legitimacy to mobility in the enterprise
• Mobility
– Healthcare, retail best use cases but
penetration becoming universal
• Collaboration
– Communicate with employees,
partners and suppliers globally
– Cross-platform mobile apps for
business applications
– Unified communications &
collaboration (UC&C)
– Videoconferencing
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
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
