  • PAUL Let me differentiate FTTP from FTTH. Shortly after we began studying Fiber in the loop scenarios, we realized we needed a common platform for both business and residence applications, due to the fact that SME locations and residences are intermingled, not just on a CO basis, but a neighborhood basis as well.

    1. 1. Beyond the Internet – Emerging Bandwidth Drivers Stuart Elby VP – Network Architecture Verizon Communications
    2. 2. Bandwidth Drivers <ul><li>Video Competition (e.g., Triple Play) </li></ul><ul><ul><li>Terrestrial MPEG/IP LH distribution </li></ul></ul><ul><ul><li>Local distribution (QAM, IPTV…) </li></ul></ul><ul><li>Ethernet is King of the Aggregation Network </li></ul><ul><ul><li>Less costly, but much less bandwidth efficient than TDM and ATM </li></ul></ul><ul><ul><li>Did I mention Video? </li></ul></ul><ul><li>Disaggregation and Mobility </li></ul><ul><ul><li>Any service, anywhere </li></ul></ul><ul><ul><li>That’s right, video </li></ul></ul><ul><li>IP Convergence </li></ul><ul><ul><li>Multi-services access (e.g., Pseudowire, IP-VPN…) </li></ul></ul><ul><ul><li>IMS </li></ul></ul><ul><li>Strong Continued Growth of the Internet </li></ul><ul><ul><li>Web-based businesses </li></ul></ul><ul><ul><li>Broadband proliferation and adoption (FTTx, xDSL, 3G) </li></ul></ul><ul><ul><li>Streaming Video </li></ul></ul>
    3. 3. DSL and FiOS – Internet Access WDM Broadband Access Metro Network Backbone Network OLT BPON Premises Verizon Online DSLAM ATM Broadband Premises Router Internet IP over SONET or Ethernet
    4. 4. DSL and FiOS – Video WDM Broadband Access Metro Network Backbone Network OLT BPON Premises DSLAM ATM Super Headend (SHE) IP VOD Server Video Hub Office Video Serving Office Internet Super Headend (SHE) MPEG2/Ethernet over SONET/DWDM
    5. 5. <ul><li>SONET platforms and DWDM Transport platforms are separate </li></ul><ul><ul><li>Multiple interconnected platforms within CO adds significant interface cost and operations complexity (hands in the plant) </li></ul></ul><ul><ul><li>Separate engineering of layers leads to sub-optimal fiber plant utilization </li></ul></ul><ul><li>DWDM is used only for inter-office transport; all traffic grooming/switching is done electronically (SONET and DCS) </li></ul><ul><ul><li>Traffic undergoes multiple electrical-optical-electrical conversions between the SONET and DWDM platforms, adding cost and added failure points </li></ul></ul><ul><li>SONET Rings are very inefficient for ‘hub and spoke’ traffic topologies </li></ul><ul><li>In 2005, Verizon developed next generation optical transport platform requirements to address these concerns </li></ul><ul><ul><li>Platform integrates DWDM Optical Ring, Optical Switching, Ethernet, SONET ADM and TDM Grooming functions </li></ul></ul>Metro Optical Network Inefficiencies
    6. 6. <ul><li>Application of next gen platform for FiOS Video Architecture: </li></ul><ul><li>Integration of SONET and DWDM functionality into a single element </li></ul><ul><ul><li>ADM-on-a-Wavelength eliminates the need for an external SONET ADM </li></ul></ul><ul><li>Larger optical reach allows transparent interconnection of a large number of offices with minimal regeneration </li></ul><ul><li>Optical mesh allows rings to be optically interconnected </li></ul><ul><ul><li>Wavelength Selective Switch (WSS) for optical switching between rings eliminates back-to-back nodes for ring to ring interconnections </li></ul></ul><ul><li>Optical broadcast reduces the cost of video distribution </li></ul><ul><li>Simplified equipment operation </li></ul><ul><li>Reduced PICS and spares inventory via fewer card types and tunable lasers </li></ul>Next Generation Optical Transport Platform
    7. 7. Video Network with Traditional Elements <ul><li>Separate networks to transport broadcast video and IP data/video-on-demand </li></ul><ul><li>Core DWDM ring and multiple SONET rings to distribute VOD and data to each VSO </li></ul>VHO Agg Office Router Agg Office Agg Office Agg Office Agg Office Agg Office Router VSOs <ul><li>Multiple SONET Rings from the VHO to distribute broadcast video to the VSOs </li></ul><ul><li>Large number of network elements including many stacked SONET rings </li></ul>OC-192 Broadcast Ring OC-192 Data + VOD Rings OC-192 VOD Rings
    8. 8. Video Network with NG-OTN <ul><li>Integrated network to transport broadcast video, video-on-demand, and IP data </li></ul><ul><li>DWDM on all spans </li></ul><ul><li>VHO office added to core DWDM ring </li></ul><ul><li>Core DWDM ring between Routers, VHO, and aggregation offices </li></ul><ul><li>Subtending rings to distribute broadcast video, VOD, and IP data to each VSO </li></ul>Router VHO Agg Office Agg Office Agg Office Router Agg Office Agg Office Agg Office VSOs Core DWDM Ring WDM Data, VOD, & Broadcast Ring
    9. 9. Major Ethernet Switching Hub Cities 350 Ethernet Switches @ ~300Gbps Switching Capacity
    10. 10. Disaggregation <ul><li>Advances in software enable common abstractions for voice, video, data objects </li></ul><ul><li>IP enables common distribution and communications treatments for multiple services </li></ul><ul><li>Next generation signaling and control architectures isolate application from access </li></ul><ul><li>The service is no longer tied to the device or network – personalization of delivery </li></ul>Any Service, Anywhere
    11. 11. What’s That? Phone TV TV Game Terminal Digital Camera MP3 Player Phone IM Chat Room Conference Room
    12. 12. IMS Vision <ul><li>Started in the wireless industry, now much broader interest </li></ul><ul><ul><li>Developed by GSM wireless carriers (within 3GPP consortium) </li></ul></ul><ul><ul><li>3GPP2 built on IMS with CDMA focus – MMD </li></ul></ul><ul><ul><li>Now the focus of much attention in other forums like MSF, ATIS, TISPAN </li></ul></ul><ul><ul><li>Most of our vendors have IMS products in development and/or trial </li></ul></ul><ul><ul><li>Initial focus of vendor IMS solutions has been within wireless networks, and on fixed-mobile convergence (FMC) </li></ul></ul><ul><li>Why IMS was developed </li></ul><ul><ul><li>Seeks to merge two successful paradigms, cellular networks (ubiquitous access) and the Internet (popular services) </li></ul></ul><ul><ul><li>Key initial objectives were: </li></ul></ul><ul><ul><ul><li>Provide QoS support for real-time multimedia services </li></ul></ul></ul><ul><ul><ul><li>Provide mechanisms for service providers to charge appropriately </li></ul></ul></ul><ul><ul><ul><li>Enable integrated services </li></ul></ul></ul>
    13. 13. Some Simple Examples <ul><li>I’m in the Anaheim Marriott and would like to watch the movie I saved on my home DVR on my laptop. </li></ul><ul><li>I’m wrapping up an OFC presentation and realize that 24 is about to go on before I can get back to the hotel, so I watch it on my mobile. </li></ul><ul><li>Multipoint HD video conferencing between homes </li></ul><ul><li>Sending my ‘trip to the F1 race in Montreal’ travel video to everyone on my buddy list. </li></ul><ul><li>Mobile Video Sharing </li></ul>
    14. 14. Backbone Traffic Growth <ul><li>Verizon’s Network: </li></ul><ul><li>>600,000 fiber route miles </li></ul><ul><li>3,200 AS Connections </li></ul><ul><li>IP traffic growth: ~ 40% y/y </li></ul>Internet circa 2000 What happens if RFID takes off?
    15. 15. Summary <ul><li>Video is the key driver to traffic growth on the optical network </li></ul><ul><ul><li>More service providers providing broadcast quality video </li></ul></ul><ul><ul><li>More devices sourcing and sinking video content across the network </li></ul></ul><ul><ul><li>More content in HD </li></ul></ul><ul><li>The trend towards Ethernet-centric aggregation networks drives more transport capacity demand </li></ul><ul><li>The dot-com bubble is ancient history; Internet traffic growth back on track </li></ul><ul><ul><li>Trend from dial-access to broadband access and 3G </li></ul></ul><ul><ul><li>eBusiness growth in both traditional and new market </li></ul></ul>
