1. MIS Fall Conference October 16 th, 2007 Patrick Capozzi Systems Engineer

2. Technology moves ahead….

3. and keeps moving ahead….

4. High Definition is Here! Manufacturers in every part of the video industry are embracing the concept and standard of HD But for an interactive application like video conferencing, HD is more than just a resolution

5. Industry Standard Terms and Resolutions HVHxVMultiplesAspect QCIF17614425,3441/44:3 CIF352288101,37614:3 2CIF or 1/2 D1352576202,75224:3 4CIF/D1704576405,50444:3 SD - 480i720480345,60034:3 ED - 480p720480345,60034:3 HD - 720p1280720921,600916:9 HD - 1080i/p192010802,073,6002016:9 SVGA800600480,000 4:3 XGA1024768768,432 4:3 128010241,310,720 4:3

7. Why does UltimateHD matter? Organizations are facing incremental communications challenges: Globalization, mergers/acquisitions and outsourcing/offshoring Travel restrictions/security, cultural/language differences, workforce mobility and telecommuting UltimateHD enhances every communication allowing customers to: Make informed decisions…faster Experience every critical detail…perfectly Share their complete work…demonstrate their full value Enhanced communications delivers the competitive edge Reduce product development cycle and speed time to market Increase collaborative teamwork and efficient knowledge sharing Improve relationships across the organization and extended teams Leverage resources and increase profitability

8. What are the benefits of UltimateHD? High definition is only a measure of image resolution UltimateHD is an experience! Polycom HDX improves each communication experience in every way with UltimateHD HD Voice allows you to distinctly hear every sound you need to hear and none that you don’t –Eliminating conference fatigue while adding richness and clarity to each voice and audio input HD Video provides the sharpest, clearest images in vivid, natural color and full motion –Never miss a single expression and savor every detail HD Content allows you to share your work in any application –From PC screens to HD doc cams and DVD players your value will come through in perfect detail and full motion

9. UltimateHD is for…. Organizations committed to faster time to market, gaining a competitive edge, and saving valuable resources Organizations that work globally over distance and/or interact with global customers, vendors or partners Organizations that value the power of clear communication and leverage that as a key asset Organizations that see the benefits of technology as a way to enhance their productivity as well as encourage and reward their employees

10. Design/Manufacturing Current Challenges: Dispersed project groups In person meetings are, at times, the only option Communicating with vendors and suppliers Benefits of UltimateHD: Enables disperse groups to work together to accomplish tasks faster, easier and with more synergy Share even the smallest details over HD Increase time to market and gain competitive edge

11. Polycom RPX Telepresence Experience Only true immersive telepresence solution that is standards-based and interoperable with traditional video conferencing Highest quality audio and video in a truly immersive environment Seamless visuals and transparent technology make this the best immersive experience in the market

12. THANK YOU THANK YOU

13. Video over IP Deployment Challenges Existing networking infrastructure is not “media-aware” Firewalls block Media (Video/Audio) calls Network Address Translation (NAT) breaks addressing Video/Audio and data traffic on shared WAN pipes degrades voice and video quality User Concerns Dialing concerns How do I call them? What should I dial? –Do I have to register with them? –Why can’t they call me? Designing around the above problems is difficult and expensive with legacy CPE hardware

14. How do you fix the problem? NAT Avoidance Uses techniques to avoid a firewall / NAT May require additional CPE NAT Traversal Video calls traverse the firewall / NAT Multiple methods available

15. One approach – Avoid the NAT problem Public IP PROXY Public – Private IP TUNNELS Virtual Private Networks (VPN)

16. Firewall Traversal Solutions Firewall Traversal Solutions Application Layer Gateway (ALG) Decentralized solution Enables a firewall to become media aware without compromising security H.460 Based Traversal ITU defined NAT/FW traversal method Centralized solution Service provider model Works with legacy firewalls

17. Firewall Traversal Solutions Firewall Traversal Solutions Application Layer Gateway (ALG) Decentralized solution Enables a firewall to become media aware without compromising security H.460 Based Traversal ITU defined NAT/FW traversal method Centralized solution Service provider model Works with legacy firewalls

18. Application Layer Gateway (ALG) Resolves Network Address Translations issues Media and protocol aware Preserves all features (Encryption/Content Sharing) Uses Stateful Packet Inspection Dynamically opens and closes ports Provides topology hiding to protect the H.323 Components (endpoints, bridges, gatekeepers) and data devices

19. Application Layer Gateway (ALG) ALG Pros Security (intrinsic Firewall) –Dynamic Port utilization for call duration Scalable - Enables Shortest Path Media Routing Less costly – no extra bandwidth Ideal for “fixed” video installations Video endpoint registration not mandatory Flexible dialing Works with any endpoint ALG Cons Not practical for mobile work force

20. V2IU in ALG Mode User at this location calls bill@video.123.com or tom@video.abc.com

21. H.460 – Traversal of H.323 across NATs and Firewalls H.460 ITU Standard Extension to H.323 Developed by Polycom, Radvision, Tandberg Approved August 2005 H.460 enables H.323 signalling and media to traverse NAT/FW installations Utilizes a Traversal Server (TS) at a central location Requires H.460 aware endpoints to register with Traversal Server (Polycom V/VSX Series Version 8.5 available now)

22. H.460 – Traversal Server H.460 Pros Allows for IP calling with legacy firewalls –IP and Port issues resolved at Traversal Server Simplistic for registered H.460 endpoints Ideal for mobile users (road warriors / hot spots / home users) H.460 Cons Extra bandwidth may be needed at Traversal Server location Requires endpoints to register with the Traversal Server Scalability - all traffic routed through the host location (signaling and media) Less Secure (Traversal Server may not be a Firewall)

23. V2IU in Traversal Server Mode (H.460) Mobile user registers with TS and calls host location using alias. V2IU Traversal Server

24. Polycom can provide a hybrid solution Outside user does not have to register with Traversal Server
