• Up to 45 Msps Outbound
• DVB-S2/ACM
• Up to 6 Inbound Return Channel Demodulators (RCD)
• Each RCD supports
• One 2 Msps channel, or
• Two 1 Msps channels, or
• Four 512, 256 Ksps channels
• Expansion rack options
• Additional RCDs as needed
• Additional IP Gateways as needed

Advanced Bandwidth Management

• Four Different Service Profiles
• Dynamic Streaming
• No Jitter And Rate Guarantees
• Bandwidth Allocation is Backlog Based
• Constant Bit Rate (CBR)
• Low Jitter
• Guaranteed Rate
• Adaptive CBR
• Medium Jitter
• Guaranteed Minimum Rate
• Predefined steps between Min and Max CIR
• Enforced Maximum Rate
• Committed Information Rate (CIR) with Best Effort
• Medium Jitter
• Guaranteed Minimum Rate

• Service profiles are set per remote not per
  Inroute or network
• Outbound and Inbound service profiles can be
  configured independently
• One Inroute Group can support any or all of the
  various service profiles

• Each session configured with the following
  parameters
• Minimum CIR (Kbps)
• Maximum Rate (Kbps)
• Step Increment (Kbps)
• Usage threshold ( of utilization)
• Idle Period (can be eternal)

• Traffic Between The Minimum And Maximum Rate
• Fixed step increments
• Flexibility Of Exceeding The Min Rate When
  Bandwidth Is Available In The Network
• Outroute CIR Allocates Resources Only When
  Outroute Data Is Backlogged.
• Inroute CIR Minimum Is Allocated Independent Of
  Backlog.
• Inroute CIR Session Is Released When Inactive For
  A Predefined Interval.

CBR V CIR

• Constant Bit Rate) A uniform transmission rate.
  For example, real-time voice and video traffic
  requires a CBR to lessen jitter. In ATM, CBR
  guarantees bandwidth for the peak cell rate of
  the application.
• Committed Information Rate ) Guaranteed
  throughput on data transmission connection

6
Traffic Management -Priorities

• Priorities Mapped Under the Three Bandwidth
  Allocation Grades in Both Directions
• Outbound
• Four Priority Queues
• Transmission Based on Priority
• Transmission Limiting Based on Priority (Lowest
  Priority First) to Stay Within the Configured CIR
• Inbound
• Four Priority Queue Maintained
• Transmission Queuing the Same as Existing HN
  System
• Flexible Rules For IP Priority Mapping
• Source IP Address Range
• Destination IP Address Range
• TCP /UDP Port Number
• Diffserv Code Point (DSCP) Bits

7
IP Bandwidth Conservation Features

• IP Packet Payload Compression
• V.44 Algorithm with lossless compression
• Stateful Compression Takes Advantage of
  Redundancy Across TCP Packets Instead of Only
  Within a Single Packet
• Builds Dictionary On-the-Fly
• Compression Ratios Up to 121
• Can Be Enabled on an Individual PEP Connection
• Header Compression
• TCP/IP header from 40 Bytes to about 10-12 bytes
• Generally reduces bandwidth by 15-20
• Multiple Types of IP Headers Compressed
  Including
• IP Header ? UDP Header
• RTP Header ? PBP Header
• PEPV3.5
• Performance Enhancement Proxy
• Reduces handshaking

AIS How It Works

• Enables highest efficiency transport at best
  quality
• Terminals Support Dynamic Inbound FEC Rate Change
• Ability to Switch FEC Rate 4/5 To Rate 2/3 To
  Rate ½ Burst to Burst Without Switching Inroutes
• Based On Signal Strength Feedback From the NOC
• Terminals Support Alternate Symbol Rates
• Ability to Change To Lower Symbol Rate Due to
  Rain Fade
• Requires Switching Inroutes
• Additionally Remotes support Uplink Power

• Inbound Group is a collection of inbound
  channels
• The channels within the Inbound Group are treated
  as a pool
• Remotes can be assigned to any channel within the
  Inbound Group
• The DNCC (Bandwidth Manager) distributes the load
  across the inroute channels
