IDirect Agrees to Sell Itself for $165 Million
By Ellen McCarthy
iDirect Technologies Inc., a Herndon firm that sells network
equipment to satellite companies, agreed to be acquired yesterday by
Singapore Technologies Engineering Ltd. for $165 million in cash.
The acquisition is the second big deal this week in the consolidating
satellite industry. On Monday, satellite giant Intelsat Ltd., which has
most of its operations in the District, said it was acquiring PanAmSat
Holding Corp. for $3.2 billion.
Under the terms of the IDirect deal, the 11-year old Herndon firm will
be acquired by Singapore Technology's U.S. holding company. IDirect
will continue to operate under its own name and existing
management team. No layoffs are expected among its 150 employees.

The iDirect GSM Backhaul
Business Case
The implementation of GSM over satellite is commonly used in many
regions of the world. Traditionally, this has been supported via a legacy
SCPC connection (as depicted above).
● In a point-to-point legacy SCPC connection, each link must be engineered
to accommodate the busy hour traffic of the access BTS.
● Satellite transmission however, is very bandwidth sensitive since every kHz
of satellite bandwidth must be leased and incurs an additional cost.
● Legacy SCPC provides a “brute force” method of solving Abis backhaul by
throwing expensive bandwidth at the connectivity requirement.
iDirect’s IP solution represents a natural evolution
that will lead to significant bandwidth reductions,
and therefore cost savings.

Why Compression?
One of the greatest challenges of broadband satellite service is
the cost of space capacity on service provider networks. This
challenge continues to intensify as more users around the globe
utilize satellite as their primary means of Internet access.
Bandwidth costs have a significant impact on the cost structure
of satellite service providers. They also have a direct impact on
a service provider’s ability to compete effectively in the market.
The key to accomplishing this balance is through the efficient
utilization of available bandwidth.

Lossy versus Lossless
Compression
Lossless and lossy compression are terms that describe whether
or not, in the compression of a file, all original data can be
recovered when the file is uncompressed.
With lossless compression, every single bit of data that was
originally in the file remains after the file is uncompressed. All
of the information is completely restored.
● TCP Payload Compression
Lossy compression is a form of data reduction. It permanently
eliminates unnecessary data in static images coming from the
Internet. Lossy compression reduces the resolution of JPEG
images coming from the Internet, but it does so in a way that
end users cannot detect the differences between compressed
and uncompressed images.
● iDirect Compression and Acceleration Server iCAS

TCP Payload Compression
The TCP Payload Compression feature provides increased
bandwidth for TCP streams on both the upstream and
downstream channels in periods of channel congestion.
● Uses zlib, an open source compression library
● When turned on, compression is activated for both upstream and
downstream for the specific remote
● Compression is activated dynamically in times of congestion. If no
congestion is present, data passes through the compression layer
unchanged
TCP Payload Compression will be available on 5xxx and 7xxx

Compressed Real-Time Protocol
(cRTP)
cRTP can significantly reduce the bandwidth requirements of
VoIP flows
● RTP-based applications utilize large numbers of small packets
● The 40-byte IP/UDP/RTP header often accounts for a significant
fraction of the total packet length.
● cRTP is a standard header compression technique.
Benchmarks
● 11.5 Kbps per voice call with G.729 compression
● 8.5 Kbps per voice call with G.723a compression
● Overall VoIP calls using cRTP achieves a 50% savings in bandwidth.

TCP Acceleration
Impact of Satellite Delay
● TCP is “window” driven to prevent receiver saturation
● Uses a “slow start” concept to reduce congestion - therefore takes
time to build up to full capacity
● Reacts to network congestion by throttling back if sender detects
lost packets
● Will confuse occasional lost packets with congestion - therefore can
over react to bit error loses

Mesh System Requirements
Hub must be able to “see” itself – no spot/hemi-beam support
Mesh remote must be able to “see” itself
BUC and antenna are sized to achieve EPEBW at the satellite –
for all remotes in Mesh IG
● the equal-power-equal-bandwidth point (EPEBW) ensures the
highest possible mesh availability
M1D1 is required as transmit line card
M1D1/M0D1 is required as receive line card
Remote must be iNFINITI 53xx or 73xx
PLL LNB is required at remote
Outroute/inroute must be on the same band and same
transponder

Star/Mesh Network Design
Benefiting from the Star Topology
● The hub maintains tight control of transmissions to and from
remotes
● A common network management system is provided through the
hub station
● Information transfer is optimized for star topology information
networks, such as those maintained by centralized corporations and
service/content providers -> the majority of data traffic still takes
the star route
74
iDirect Proprietary & Confidential
Star/Mesh RF Network Design
RF design for mesh operation
● With Star topology, the RF design of the return link can be
arranged to minimize dish size and transmit power at the remote
VSAT. The resulting weak carrier signals can be received by the
larger diameter hub station antenna; VSAT (very small aperture
terminal) is the remote Earth station in the star network
architecture
● With Mesh design, the VSATs need to be dimensioned appropriately
to allow remote-to-remote mesh connectivity
Link Budget Implications
● Generally 25% of standard Star throughput
 If Star LBA is 2 Mbps, then Mesh would be about 512 kbps
● Network Design Implications
 Additional Overhead involved (2 bytes + SAR)

Star/Mesh Operation
Star/Mesh is basically an overlay model, and will be tuned in
iDS release 7.0 towards VTC and VoIP (UDP) traffic.
The mesh traffic can be triggered on a service level basis.
For a VoIP call, this means that a remote will send voice
signaling (TCP) over a star (remote to hub) topology and
RTP/cRTP traffic (UDP) via a direct remote-to-remote meshing.
77
iDirect Proprietary & Confidential
Phased Mesh Release
Phase 1: Single Carrier Only
● Can have multiple SINGLE Carrier Mesh inroutes sharing One OB
● UDP traffic only
Phase 2: MF-TDMA based Multi-Carrier
● All Carriers have to be same size, FEC, Modulation
● Support for both UDP and TCP traffic
● Encryption support; TRANSEC over mesh link
Phase 3: MF-TDMA based Multi-Carrier
● Different size inroutes
 probably sized in multiples of a smallest carrier
 256, 512, 768, 1024, etc.

iDirect Star/Mesh Benefits
Benefits
● Meets most “Mesh” requirements of Star/Mesh
● Generally Smaller Antenna’s / ODU’s
● MF-TDMA with Adaptive Channels Increase Efficiency
● Higher System Efficiency than Full Mesh
● Simpler System Management
 Adding Capacity is Just Adding another Inroute
 Do not have to “Touch” every site
 Centralized Statistics Collection and Availability
Other Star/Mesh characteristics:
● Not Full Mesh – We can operate like one, but the efficiency benefits
are with star/mesh operation
● Not SCPC Mesh – TDMA star/mesh is more scalable and bandwidth
efficient
● General Scalability Issue – Number of concurrent connections
depends on carrier size
● All remotes in a mesh inroute must be mesh capable

 SCPC overhead typically takes 2.5% of gross kbps after error
correction
iSCPC is like SCPC except…
● iSCPC is a term invented by iDirect. It is not standard industry
jargon.
● iSCPC interfaces only with IP. It has no clear channel mode.
● iSCPC includes built-in networking and applications layer software:

    20 iDirect Proprietary &Confidential The iDirect GSM Backhaul Business Case The implementation of GSM over satellite is commonly used in many regions of the world. Traditionally, this has been supported via a legacy SCPC connection (as depicted above). ● In a point-to-point legacy SCPC connection, each link must be engineered to accommodate the busy hour traffic of the access BTS. ● Satellite transmission however, is very bandwidth sensitive since every kHz of satellite bandwidth must be leased and incurs an additional cost. ● Legacy SCPC provides a “brute force” method of solving Abis backhaul by throwing expensive bandwidth at the connectivity requirement. iDirect’s IP solution represents a natural evolution that will lead to significant bandwidth reductions, and therefore cost savings.

    57 iDirect Proprietary &Confidential Why Compression? One of the greatest challenges of broadband satellite service is the cost of space capacity on service provider networks. This challenge continues to intensify as more users around the globe utilize satellite as their primary means of Internet access. Bandwidth costs have a significant impact on the cost structure of satellite service providers. They also have a direct impact on a service provider’s ability to compete effectively in the market. The key to accomplishing this balance is through the efficient utilization of available bandwidth.

    58 iDirect Proprietary &Confidential Lossy versus Lossless Compression Lossless and lossy compression are terms that describe whether or not, in the compression of a file, all original data can be recovered when the file is uncompressed. With lossless compression, every single bit of data that was originally in the file remains after the file is uncompressed. All of the information is completely restored. ● TCP Payload Compression Lossy compression is a form of data reduction. It permanently eliminates unnecessary data in static images coming from the Internet. Lossy compression reduces the resolution of JPEG images coming from the Internet, but it does so in a way that end users cannot detect the differences between compressed and uncompressed images. ● iDirect Compression and Acceleration Server iCAS

    59 iDirect Proprietary &Confidential TCP Payload Compression The TCP Payload Compression feature provides increased bandwidth for TCP streams on both the upstream and downstream channels in periods of channel congestion. ● Uses zlib, an open source compression library ● When turned on, compression is activated for both upstream and downstream for the specific remote ● Compression is activated dynamically in times of congestion. If no congestion is present, data passes through the compression layer unchanged TCP Payload Compression will be available on 5xxx and 7xxx iNFINITI remotes with iDS 7.0
