    The Connected Enterprise:

    An Overview of Today‟s Key Enterprise

    Network Technologies

  • Summary

    This session takes a market perspective and explores

    the growth of key network technologies that enterprises

    are weaving together to support the distributed

    enterprise in remote and mobile offices. Areas of

    discussion include VoIP and enterprise telephony,

    unified communications (UC) and collaboration, WAN,

    wireless and mobility technologies.

  • Agenda

    • Dynamics of the Cloud Era

    • Market Landscape

    • Vision for the New Network

    • Essential Guidance

  • Key Themes Driving Enterprise Network





    The enterprise network is evolving from a fixed, data-centric,

    client server topology to an application-driven, multi-media and mobile

    network, that is more closely aligned with business needs than ever before.

  • Continued Growth in the WW Enterprise

    Network Equipment Market

  • U.S. Unified Communications

    Market Forecast

    *2009 to 2014 U.S. UC CAGR = 13.3%

    2010 Market Size = $7.7b

    WW IP Telephony Revenue ($ millions)

    - CAGR of 10.7% for forecast period – Source: IDC, 2011

  • 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

    WW Videoconferencing Revenue ($ millions)

  • Key CIO Initiatives - Networking

    •Need to reduce/optimize IT resources in

    a tough economic environment

    •Support for new emerging applications

    (VoIP, Video, WLAN) and devices

    (smart-phones, tablets)

    •Integrated, seamless manageability

    across the network and remote sites

    •New virtualization services for both data

    and communications (UC)

    •Scalable infrastructure

    - increased traffic

    - new sites

    - new services

  • Exploding Traffic Growth Stressing Networks:

    Datacenter to the Edge

    • Data centers have become the cornerstone of business…










    …but the edge of the network is undergoing its own transformation. center.jpg&usg=AFQjCNG6RqRZhe1_eJbIjE5x9zFNso_I9w

  • Enterprise Networking Forecast by Technology

    – 2011

  • 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

    Data center App Virtualization

    Converged Infrastructure

    Edge/Branch Remote Branch

    Real-time applications

    Campus Simplicity Wired/Wireless  Increased Bandwidth

    Mobile Access Remote/Teleworker

    Smart Device User





  • 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,


    – Optimized Traffic Separation,


    – Automation

    – Regulatory, Compliance

    • Built-in Intelligence based on user, device, application

    and location

  • Adding Network Intelligence







  • 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


  • 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


    • 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?
