Bandwidth & Power Efficiency

How to Reach the Highest User IP Bits / Hz

• Satellite Bandwidth is the single largest

operating expense for a satellite network

– Higher bandwidth (and power) efficiency and

utilization has a direct impact on performance &

profitability

• Need to incorporate optimization to deliver

– Highest user IP bits / Hz

– Highest user IP bits / Amplifier Watt

• Requires best in class optimization

– Header Comp, Payload Comp, WAN

Optimization, Bi-directional ACM and Power

Control

Reduce Total Cost of Ownership (TCO)

H-DNA

Why Have a New Type of Return Access?

• H-DNA (Heights Dynamic Network Access)

• Like MF-TDMA, it will change capacity in response to

a change in traffic from the remote to the hub

• H-DNA switches at MF-TDMA like speed, but without

the amount of jitter introduced by a MF-TDMA switch

• Best of all for the end user; H-DNA adds

approximately 2% overhead compared to what MF-

TDMA adds; 15 to 25% overhead

• Much more efficient utilization of return bandwidth

14

Higher Layer Optimization

• IP Optimization

– Header & Payload compression, Reduces bits transmitted over

satellite

• WAN Optimization

– TCP/http acceleration; improved user experience

– Image smoothing; reduces bits transmitted over satellite, faster

downloads, frees up capacity

– Caching; instantly serve cached content, improved user

experience

• Fully integrated with Multi-tier QoS

– Prioritize mission critical and revenue generating traffic over best

effort traffic

There’s a Catch

Internet Traffic and Encryption• Sandvine predicts that “by the end of 2017… Internet traffic is

more than 75 to 80% encrypted in most markets. “

• It is expected that Internet encryption levels will stabilize at

roughly 90% within the next 2 yrs.

• Limits payload compression; effects transport efficiency

• Class leading, bit/hz performance and economics

Optimized and Efficient Waveforms

• 250x200Mbit/s uncontended throughput

• Class leading packets per secondHigh Performance for demanding applications

• All available Spectrum always used

• All available Bit’s always made availableRealtime capacity allocation based on network-

wide demand

• Realtime lossless payload compression

• Enhance Application behaviorLink and WAN Optimization

• Multicore, field upgradable remote

• Flexible, freely upgradable hub architectureFuture proofed performance

and Scalability

With Superior QoE, and Robustness

• Applications run uninterruptedZero packet loss, zero duplicates and zero out

of sequence packets

• Superior voice and video quality

• Interactive applications don’t experience timeouts

Do not introduce TDMA like jitter and latency

• Faster response for interactive application

• Superior voice and video qualityHigh performance packet processing keeps

latency and jitter to a minimum

• Much more responsive web experienceIntegrated WAN optimization (TCP / http

acceleration) speeds up web based applications

• High priority users and applications protected from network congestion

Multi-tier QoS ensures that mission critical and revenue generating traffic is prioritized over

best effort / low priority traffic
