The Real-Time Middleware CompanySM

“The most profound technologies are those that disappear. They weave themselves into the fabric of everyday life until they are indistinguishable from it.”

-- Mark Weiser, 1991 Scientific American article

on Pervasive Computing

“The shift today is from thinking about servers and objects and code to thinking only about information flow. The network can bring everything you need to know, now.”

-- RTI 2006, The Real-Time Middleware Company

Who is RTI?

� Experts in real-time information management for distributed systems� Founded out of the Stanford Aerospace Robotics Lab in 1991� Active in standards, including OMG, NCOIC, Eclipse, Open Group� Sustained growth. Strong financials.� Values: Commit to customer success� Mission: Lead real-time communication middleware

Market Leadership

� ~400 different publish-subscribe applications– 75 DDS API applications

� 20+ major Navy programs

� All major US primes

– Thousands of deployments

Navy Open Architecture Ship Self Defense System (SSDS)

� Project to employ standards throughout ship systems (frameworks, OS, etc.)

� Goal: Reduce total cost of ownership, ease system upgrades, reduce interoperability issues

� RTI Services provided advanced integration, support & consulting

� First deployment at sea now

DD(X) U.S. Navy Destroyer Program

� Developed under the DD(X) destroyer program, DDG 1000 Zumwalt is the lead ship in a class of next-generation, multimission surface combatants

� RTI powers the Total Ship Computing Environment Infrastructure (TSCEI), the backbone of the network computing system and basis for all DDG 1000 application software programs

� “The selection of RTI came through a process which uses formal evaluation criteria and a source selection board to ensure that the Navy gets the best value. This is an emerging product market and it was determined that the offering from RTI, a small privately held company, provides the best value to the Navy.”

-- Raytheon DDG 1000 System Software Development Director Bob Martin

DDS Latency Comparison

� Latency comparison – RTI’s fundamental networking is faster than other DDS

implementations– RTI’s latency doesn’t significantly increase with message size

Scalable Throughput

� RTI is up to 10X faster than others– RTI saturates the network at 16KB

� Saturation of receiver network buffers cause message loss� RTI is faster, so it saturates the network sooner

– RTI in reliable mode is always faster� This “diminished throughput” anomaly is caused by using

BEST_EFFORTS. � In reliable mode, RTI is always faster
