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 CaseThe 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?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 CompressionLossy 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 CompressionTCP 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

Compressed Real-Time Protocol (cRTP)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.

● Star/Mesh operation



TCP AccelerationTCP 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 RequirementsMesh 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 DesignStar/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


Star/Mesh RF Network DesignStar/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 OperationStar/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.


Phased Mesh ReleasePhased 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 BenefitsiDirect 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
