  33. 33. ViaSat Proprietary DVB-S2 Technology for Highest Downstream Efficiency LinkStarS2A with DVB-S2 typically uses 30-40% less satellite bandwidth than DVB-S: LDPC Coding eliminates 8% Reed Solomon overhead. 1.2 carrier spacing uses 11% less bandwidth than 1.35 Includes QPSK, 8PSK, & 16APSK waveforms LinkStarS2 is field proven in more than 40 networks worldwide
  34. 34. ViaSat Proprietary LinkStarS2 “DLA” Technology for Highest Upstream Efficiency LinkStarS2 “DLA” – Dynamic Link Adaptation eliminates wasted satellite capacity for rain margin Upstream carrier operates at most bandwidth efficient symbol rate & coding during clear sky Rain faded sites automatically undergo two dimensional rain compensation 1. Automatic change to more robust FEC (e.g. 6/7 to 2/3) 2. Automatic change to lower symbol rate Reduces upstream satellite bandwidth by up to 18% Carrier Frequency Spectrum with DLA -20 -15 -10 -5 0 5 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Transponder Frequency (MHz) Carrier Frequency Spectrum without DLA -20 -15 -10 -5 0 5 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Transponder Frequency (MHz) 16 MHz Qty 20 x 625 ksps FEC = 2/3 carriers 13.2 MHz Qty 16 x 625 ksps FEC = 6/7 carriers + qty 1 x 312 ksps carrier for fade mitigation
  35. 35. ViaSat Proprietary Bandwidth Efficient Upstream Access Schemes Optimize Satellite Bandwidth Usage Committed Information Rate (CIR) Provides guaranteed bandwidth Bandwidth on Demand (BOD) Reduces bandwidth usage by allocating bandwidth only when needed from common pool Carrier Load Balancing - Dynamically balances the load among all inbound carriers based on traffic activity for efficient bandwidth utilization Slotted Aloha Fast response time for bursty traffic Efficient for narrowband/transactional traffic CIR Reallocation Provides guaranteed bandwidth when needed Bandwidth available to common (BOD) pool when not needed Optimized satellite bandwidth usage = reduced OPEX costs
  36. 36. ViaSat Proprietary Efficient Access Schemes (con’t) Multi-channel Traffic Burst Improves efficiency by dynamically allocating one big burst instead of multiple small bursts for large data rate requirement Multi-frame Traffic Burst Allocates available bandwidth to larger quantities of remote terminals Multi-frame CIR Ensures guaranteed bandwidth for larger quantities of remotes for narrowband applications Application Triggered BoD Enables broadband access to the hub without compromising transactional traffic Triggers immediate high speed BoD channel based on customer specified parameters Application Triggered CIR Similar scheme as Application Triggered BoD, but assigns CIR channel Ideal for voice and videoconferencing applications
  37. 37. ViaSat Proprietary Quality of Service Site Level QoS Prioritizes IP and satellite resources within the RCST Mandatory for time sensitive applications like voice over IP (VoIP) and videoconferencing Sets priority with Diffserv based 6 classes of service Honors priority from other devices via TOS byte Network Wide QoS Prioritizes upstream satellite bandwidth by site • Ideal for military applications Prioritizes upstream satellite bandwith by application • Ideal for voice services Three levels of prioritization

  41. 41. ViaSat Proprietary Solving Network Performance Challenges Compression Dramatically reduce bytes uploaded and downloaded to increase effective bandwidth available Round-trip reduction Reduce the round-trips required to complete transactions to dramatically improve perceived application performance Optimized Transport Replace TCP with a transport that performs optimally over problematic links, reduces retransmissions and increases network utilization
  42. 42. ViaSat Proprietary Benefits of Transport Optimization With Compression Without AcceleNet With AcceleNet ITP With AcceleNet ITP + AcceleNet Compression *results based on third party testing 50-75% bandwidth reduction Transport Optimization
  43. 43. ViaSat Proprietary Optimized Application Performance HTTP Servers Enterprise Email Servers AcceleNet improves effective Bandwidth, network utilization, and measured performance • Fewer bytes transferred • Single Round Trip • Minimal Retransmissions • Optimal use of network Server Client
  44. 44. ViaSat Proprietary AcceleNet Architecture T1, DSL, satellite, dial, cellular Radius authentication TCP data encryption No open listening ports Desktops, laptops, PDAs, Smartphones
  45. 45. ViaSat Proprietary HTTP Acceleration Benefits: 90% reduction in number of round trips AcceleNet Proprietary HTTP proxy models the browser cache to avoid downloading cached objects. Software solution provides significantly more object buffering than possible on any modem. Greater bandwidth savings and faster performance than any modem- or client-based solution on the market today. Uniquely pre-fetches ALL objects in a single request, including dynamically-generated URLs; industry’s highest pre-fetch ratios are achieved.
  46. 46. ViaSat Proprietary Data Reduction-Compression 75% average bandwidth savings in both directions Patented and custom modules compress HTML and other web-specific objects Large Browser History with multiplexed connection history sharing Large history buffers shared across all TCP connections in a session. Variable image and multimedia compression Further compression and content filtering of images (.jpg, .gif, .bmp, .png, etc.) and multimedia files (.swf) providing even greater bandwidth savings. Dynamic Compression Engine Selection ‘on the fly’ to determine appropriate compression techniques. Browser cache verification Guarantees that cache is never stale; maintains most current content. AcceleNet replaces TCP with proprietary more efficient ITP (Intelligent Transport Protocol) protocol; header compression can save some bandwidth but AcceleNet has completely eliminated this problem.
  47. 47. ViaSat Proprietary Transport Optimization Benefits: 8x greater throughput Bi-directional flow control ITP maximizes link utilization by measuring the characteristics of the connection and automatically adjusting the data flow; greatly outperforming basic techniques like TCP and connection establishment spoofing which provide limited benefit. ITP maintains over 95% bandwidth efficiency with packet loss up to 3% while TCP based connections bandwidth efficiency drops to less than 35%.Packet-based accountingBetter packet-loss handling; outperforms stream-based techniques. Multiplexed TCP connections; Uniquely optimizes the link over multiple TCP connections instead of each TCP connection, providing much greater performance especially for web browsing, which uses multiple TCP sessions per site. Application-aware optimization; Improves bandwidth efficiency with advanced retransmission decisions based on type of request; e.g., HTTP GET request vs. dropped packet in a file transfer. ACK reduction; Improves bandwidth efficiency; acknowledges 64 packets in a single ACK.

  58. 58. ViaSat Proprietary Patented ViaSat PCMA technology allows 2 different satellite signals to operate on the same frequency Signal cancellation = BW savings Frequency f1 f2 W Hz W Hz Before Frequency f1 & f2 W Hz After Bandwidth savings can be as much as 50% !! Applicable to any modulation / FEC technique

  63. 63. ViaSat Proprietary Operational Considerations Link requirements Full-duplex circuits only (symmetric or asymmetric) Must be able to receive your own uplink signal (doesn’t work with cross-strap transponders) Implementation considerations Power is slightly increased over standard frequency pair approach (0.15 to 0.5 dB depending on near/far ratio) May need to change existing coding rates and modulation to take advantage of bandwidth reduction • Link budget analysis will determine link configuration and estimated overall savings of power and bandwidth with PCMA New services can be designed to maximize savings (e.g., optimal antenna size) Products DAMA – StarWire • 64 kbps - 2 Mbps SCPC modem integrated into network Hub Canceller • Hub-Spoke – ArcLight (Broadband, Gov. programs) • High-speed trunking Point-to-point
