5 Layers of Bandwidth Savings
What is LinkIP?
• Highly integrated link optimization and bandwidth
management solution for satellite networks
• Multi application, multi-protocol LAN to WAN
router
• Interfaces with a variety of devices
– Serial interface with satellite modems
– Ethernet interface with local network equipment
– E-1 interface for telephony applications
• Bandwidth savings achieved via:
– LinkShrink - integrated data compression engine
– LinkCast - multipoint dynamic routing over satellite
– SCAN bandwidth manager
LinkIP Features
• Advanced IP router adapted for satellite environment
• Bandwidth efficient multi-application platform
• Combines multiple satellite modulators and demodulators to
form a unified interface
• Supports Synchronous, Asynchronous, E1, T1, OC1-2-3, FR , ATM
and other data interfaces
• Supports digital video Interfaces (ASI, LVDS, HSSI)
• Integrated compression and encryption of selected WAN or LAN
ports
• Integrated multi application software control system (audio,
telephony, video, C&C, DB mirroring, etc)
• Works within any network topology – Star, full mesh, partial
mesh, point-to-point
• Interfaces with all types of SCPC satellite modems

Where LinkSat Fits Into the IP Stack:
Layers 1.5, 2, & 3
LinkIP v3 Edge
• 1U Chassis in 1, 2, and 4 WAN port configurations
LinkIP v3 Core
• 2U chassis w/ 4, 8, 12, and 16 WAN port configurations
LinkShrink Data Compression
• LinkSat’s proprietary lossless, low latency data
compression engine
• Compresses packet headers and payload
• Multiple compression engines run simultaneously on
LinkIP: low latency & zero latency payload compression
engines run in parallel
• Makes data compressibility decisions automatically
• Processes packets based on packet characteristics
• Compression decisions based on any combination of
QoS, ToS, IP protocol, UDP port, and/or TCP port
• Compression ratio achieved depends on compressibility
of data; VoIP can typically be compressed 30-60%
• Compression can be configured per LinkIP WAN or LAN
port and can be independently configured on each port
• Outperforms all other competitors’ compression
solutions
LinkIP Advanced Routing
•
•
•
•
High performance, high throughput wire speed router
Based on Linux Advanced Routing and Traffic Control (LARTC)
10/100/1000 Ethernet ports
Dynamic routing
– OSPF , BGP, RIP v1 & v2 / ISIS and other protocols supported
– LinkCast - Unique addressing scheme enables dynamic routing in satellite
multi-destination networks
• Policy routing
– Bandwidth control mechanism for sharing bandwidth amongst different
routes
– Prioritizes traffic by type, source, destination, port number, and custom
tagging
• Traffic Shaping
– QoS / ToS
– Differentiated Services (DiffServ)
• Router egress queue used as controlled buffer by SCAN bandwidth
manager
LinkCast Dynamic Routing
• LinkIP’s unique layer 1.5 transport protocol enables
dynamic routing within RMD architecture
• Multiple layer 2.5 point-to-point links are shared over
each broadcast carrier
• OSPF used as interior gateway protocol, and BGP used
as exterior gateway protocol
• Allows automatic rerouting of traffic if a route fails
• Easy network configuration – simply add new routes
into local LinkIP and OPSF/BGP updates network
routing tables
• Works in concert with LinkShrink compression
Routed Multi-Destination (RMD) Network Architecture
• LinkSat’s unique, highly efficient networking scheme
• Allows both MESH and STAR network configurations
• Single outbound carrier transmitted from each site
– Outbound packets for entire network aggregated onto one carrier
– 10-20% bandwidth savings realized through statistical
multiplexing of outbound IP traffic
– Single transmit carrier - no intermod products = smaller PA’s
• Multiple receive paths
– Multiple demodulators at each site, each tuned to an outbound
carrier from another site
– Enables full or partial mesh networking
– LinkIP filters and routes packets at receive sites
• LinkCast - unique addressing scheme enables dynamic
routing in RMD networks without Ethernet overhead
Routed Multi-Destination Meshed Trunking
Full Mesh Spectrum
• One outbound carrier per
site
• One modulator and three
demodulators at each site
• LinkIP packet filtering routes packets bound for
its LAN and discards the
rest
Routed Multi-Destination STAR
RMD STAR Spectrum
• Hub and spoke network
• Single outbound carrier
from hub
• SCPC return channels from
remotes
• Partial mesh with addition
of demod at remote
SCAN
• Scanned Channel Assigned Networking
• LinkSat’s Patented bandwidth manager (US Patent #
7,376,418)
• CS-FDMA-CD - Carrier Sense-Frequency Division Multiple
Access-Collision Detection
• Every remote site in network has its own SCAN bandwidth
manager
• Uses real time spectral analysis of space segment channels
to determine when and where to transmit and when to
receive a demand assigned carrier
• Utilizes same technique for transmit and receive traffic
• Satellite effectively becomes an Ethernet switch in the sky
SCAN Features
• Gives each network node its own “eyes” to watch
network spectral activity
• Advantages of both DAMA and TDMA in a single
bandwidth manager
• Distributed intelligence: no hub or central network
manager needed
• Enables single hop remote-to-remote full mesh
communications
• Fast circuit set-up times – measured in milliseconds
• Each site autonomously makes its own bandwidth
acquisition decisions
• No hub intervention or control channel required for
remote bandwidth access – faster, more reliable
• Can be provisioned as a complete network solution or
as an overlay to existing networks
• LinkIP provides modem interface and control
SCAN Advantages
• Supports all network architectures – Star, partial-mesh,
full-mesh
• Bandwidth-on-demand up to 155 mb/s (with use of
external modems)
• Bandwidth allocation is demand-driven by network users
rather than using pre-assigned slots
• Channelized bandwidth scheme allows for easy addition
and subtraction of channels to optimize the balance
between bandwidth cost and network congestion
• Lower network hardware and software license costs vs.
incumbent technology (TDMA and DAMA) for small to
medium sized networks
• Allows full satellite network automation
• Ideal for bandwidth-on-demand applications
SCAN Spectrum Analyzer

Form factor of analyzer is PCI-e PCB
Performs on-board processing of spectral data for
SCAN bandwidth manager
Detects spectral density, occupied bandwidth and
carrier power
Processes 125 MHz of bandwidth data in a single
sweep; can process 500 MHz in <5 milliseconds
Can be self contained in its own 1U chassis
Can be integrated into LinkXX router PCI-e slot
Integrated spectrum analyzer GUI
SCAN Channel Map
• SCAN spectrum analyzer can resolve both spectral density and
occupied bandwidth
• Allowable channels within a bandwidth segment are defined
by network operator
• Spectrum can be further sub-divided in separate layers with
different channel schemes, allowing fine granularity
• LinkIP determines carrier size needed based on incoming data
ToS and satellite channels available
