It's an opportune time for up-and-coming conferencing service providers to deploy collaboration solutions based on VoIP architectures. Early adopters amongst the Conferencing Service Providers (CSPs) have demonstrated the benefits and cost-efficiencies of these technologies in large hosted conferencing deployments. Now is the time for smaller or emerging market CSPs still operating legacy TDM audio bridges to embrace IP-based audio conferencing platforms, and capture your fair share of the growing hosted collaboration market opportunity.

What Attendees will learn:
* Understand the trends and key requirements for business customers using hosted conferencing services, and how traditional TDM audio bridges are not keeping up.
* Learn how IP-based conferencing platforms not only deliver cost-efficiencies in hosted conferencing services, but they also offer the flexibility to seamlessly integrate into collaboration processes and communication behaviours of your target markets.
* Understand the equipment and features required in entry-level systems to get you started, with the scalability to grow, or add video and web collaboration capabilities.

  • THE TYPE OF TRAFFIC IS CHANGING: LESS STORE-AND-FORWARD MORE INTERACTIVE
    P2P = games, voice, music, and video files
    Video Content = exclusively video content: video caching & streaming
    Video Communication = Video content + interactivity
    The bandwidth challenges ushered in by online video sites (YouTube, MySpace, etc) is just the initial phase of the impact of internet video on the network.
    Static video such as video clips and films addressed with content distribution, and live video events will eventually be enabled by internet multicast. In general, video content can be pushed to the edge since it does not change real-time. With video calling, video sharing, interactive gaming, and Enterprise TelePresence, however, the traffic must travel over the long-haul network and cannot be cached.

    2. 2. Agenda Visual Communications Over The Internet?! The Challenges of the Public Internet Making Real-Time Video Work About RADVISION
    3. 3. Visual Communications Over The Internet?
    4. 4. Visual communications is happening
    5. 5. Used to bridge geographical barriers The Number of Consumer Video Conferences projected to grow by more than 8 times between 2010 and 2015. - GigaOm, 2010
    6. 6. Gopher, FTP WWW P2P Video Content Video Communication Dominant Traffic Type 1993-1995 1995-2000 2000-2013 2013-2025 2025+ 1995: Web overtakes Gopher, FTP 2000: Peer-to-Peer overtakes Web 2013: Video Content overtakes Peer-to-Peer 2025: Video Communication overtakes Video Content Source: Cisco 2010
    7. 7. For Visual Communications, Quality is Key
    8. 8. QoS costs…
    9. 9. So why not use the Internet?!
    10. 10. Poll question: What are the main challenges for using the Internet for real-time video? Packet Loss Insufficient Bandwidth Delay Finding who/how to call Etiquette peripherals on the other side
    11. 11. The Challenges of the Public Internet
    12. 12. Video flows in pipes… Output Input
    13. 13. If the pipes don’t have enough capacity… Delay Output Input Packet Loss Congestion
    14. 14. Typical IP Network Impairments Corruption Corrupted packet rejection Multi-path Collisions Congestion Dropped by router / switch Packet Loss
    15. 15. Jitter TX RX T T+2Δ T+4Δ T+Δ Typical IP Network Impairments
    16. 16. Packet loss significantly reduces quality!
    17. 17. Too many users Too many tasks Home Worker/Road Warrior There is no such thing as enough bandwidth…
    18. 18. Productivity is the name of the game By EOY 2011 ~75% of US workforce will require mobile capabilities WW mobile workers increase from 759M in 2006 to >1Bn by 2011
    19. 19. Low delay No artifacts The right bandwidth High definition resolution High quality codec High quality peripherals High Quality of Experience Check-list
    20. 20. Making Real-Time Video Work Technologies and Solutions
    21. 21. Effective Bandwidth Estimation & Adaptation
    22. 22. How does it work? Packets Delay! Output Input
    23. 23. Look for congestion and solve it before packets are dropped
