An IT Managers Perspective

• Rob MilneIT Manager Asia-Pac

2
Whats happening in IT

• Doing more with less
• IP Convergence
• High availability
• Moving away from disaster recovery to an
  availability situation
• Distributed on-line storage
• Security
• Corporate governance, Sarbannes-Oxley
• Bandwidth and Reliability

3
Technologies for Convergence

• Voice - VoIP
• Video Digital TV, HDTV, video conferencing
• Security, CCTV IP cameras
• Storage SAN - iSCSI

4
IP Convergence Report Card

• Third annual Optus IP Index - 2004
• IP VPNs 46 growth in 2004
• 94 of IP VPNs provide access to accounting and
  financial applications
• 4 out of 5 respondents no longer regard business
  grade VoIP as an immature technology
• 50 of respondents have or are deploying a full
  IP Telephony solution with PSTN gateway

5
VoIP to Dominate

• The question is no longer if, but when VoIP will
  become the new standard for voice traffic
• The barriers to adoption being hurdles in VoIP,
  performance, reliability and security Cathy
  Martine, ATT Senior Vice President
• 40 of business lines (or 180 million lines) to
  be IP by 2009 IDATE
• VoIP represents a threat to PSTN services
  comparable or greater than mobile substitution
• Routers and packets are simply more efficient
  than switches and dedicated circuits Ovum
• The true benefits of IP telephony are in smart
  applications built around solving business issues
  in a cost effective way an IP network creates

Changes in the IT Department

• Doing More with Less
• Shift to TCP/IP
• Power over Ethernet (PoE 802.3af)
• Move to Realtime Applications
• Trend towards Distributed Computing
• Bandwidth Hungry
• Bandwidth vs. Packet Management - QoS

Pushing the Envelope of Copper Connectivity
7
Shift to Application-Driven Enterprise
Expanding Application Diversity
Limited Application Diversity
Disparate LAN/WAN/Voice Networks
Unified IP Network
Shift From Managing Connectivityto Managing
Productivity
8
Realtime IP

• Ensuring Quality of Service (QoS) and
  error-free bandwidth

• Generally 80 of data traffic is bursty and 20
  is more steady
• We are now starting to encounter a reverse rule
  toward 20/80
• Video-on-demand
• Real time e-business applications
• IP Telephony
• Unified Communications
• HDTV over the network
• Distance Learning
• Distributed Computing Clusters, SANs
• Security

IP Science for Realtime Applications
Contributing Factors

• Network Design
• Network Management
• Packet Loss
• Packet Sequencing
• Packet Prioritisation
• QoS Policy
• Scalability
• Silence Suppression
• Transcoding
• WAN Protocols

• Available Bandwidth
• CODEC Selection
• Delay (End to End)
• Full Duplex Transmission
• Echo
• Endpoint Characteristics

A Meeting of Expectations

• Typical Data Network
• 99.5 Availability
• Typical Voice Network
• 99.999 Availability
• Voice, video and storage are realtime
  applications
• An IP converged network demands that the
  underlying network infrastructure must be
• Delay intolerant, reliable and robust
• Provide for at least 99.999 Availability
• The five nines !

Home NetworkingThe need for the Triple Play

• Voice, Video, Data
• Broadband ADSL, FTTH
• Entertainment
• Product convergence

12
The Home Network Arrives

• Cheap Broadband services
• Low cost networking gear
• Ease of network configuration
• Commodity hardware pricing has enabled the home
  network
• The Need for the Second PC

13
Enter IP

• TCP/IP
• The commodity home network enabler
• Benefits of IP now moving to the home
• Proprietary based home technology solutions will
  give way to open standards based IP devices
• Lighting, heating, HVAC
• PoE

New Consumer Technologies Services

• IP to and in the home to deliver a new range of
  entertainment and services
• VoIP
• Music distribution
• TiVo
• VoD
• HDTV
• Interactive television
• IP enabled Appliances
• Security, Environment

16
Music Distribution

• The revolution is underway
• Physical distribution of music to disappear
• Music delivered direct to the entertainment
  centre/device

17
Video on Demand

• Video on Demand services over IP networks
• Convergence in advances of DSL technologies, MPEG
  video compression, and Gigabit Ethernet
  technologies
• VoD provides entertainment-on-demand by taking
  advantage of the IP network's two-way
  communication capability
• Subscription based pay per view service
• New opportunities for Telcos and Service
  providers

The New Science of Networking

• Realtime IP bit error intolerant
• Bandwidth requirements
• 1Gb -gt 10Gb Ethernet
• 250MHz -gt 650MHz
• Signal to Noise
• Power over Ethernet and soon HPOE
• IT Manager will expect it to work
