Stratogis Networks

Defense Networks

Advances in radio and satellite technology coupled with the migration to an all IP network have made Defense networks significantly more capable and complex. Stratogis has worked with OSD, JTRS, WIN-T, DISA and a number of large defense contractors to design, analyze and optimize radio, satellite and terrestrial equipment and architectures to meet tactical and strategic needs. We have built a wide range of analysis models and collected performance data on thousands of operational links. These capabilities make Stratogis ideally suited for supporting technical, operational and strategic decision making. 


Stratogis led two large network capacity utilization studies for ASD NII, DISA and MJPO. We were given access to multiple years worth of NetHealth and NetFlow traffic log data for thousands of DoD fiber and satellite circuits. The first study sponsored by OSD C3I and the MJPO evaluated CENTCOM and PACOM bandwidth usage from 2002 through 2004 which included major ground combat operations in Iraq. The second study, sponsored by ASD NII, evaluated global DoD bandwidth usage on over 4000 circuits from 2005 through 2009. The results of both studies were used to assess DoD provisioning accuracy, evaluate capacity surges during combat operations, and develop traffic models for fixed and tactical nodes.

Stratogis was tasked by OSD to evaluate the bandwidth and cost savings that could be realized by migrating commercial FDM satellite circuits to more efficient, bandwidth-on-demand technologies. We evaluated link usage in Iraq and Afghanistan over a three year period which included troop surges. The study found the majority of satellite circuits were properly provisioned for peak demands, but current FDM technology resulted in significant over provisioning at the theater level. In particular, we found real-time  bandwidth demand was uncorrelated across an AOR.  Stratogis built a predictive model for re-planning circuit provisioning based on previous usage data. The model showed that significant cost savings could be realized with virtually no risk of insufficient capacity during peak periods. Also, we found that additional savings could be had by integrating real-time bandwidth-on-demand technology into DoD SATCOM networks. Our analysis showed that by implementing these innovative bandwidth management strategies the DoD could reduce commercial satellite lease costs between 40% and 55% with little impact on network performance.

Stratogis has worked with ASD NII and DISA to evaluate the performance of Legacy IP-based and Service Oriented Architecture (SOA) applications at the tactical edge. We developed the Performance Evaluation Tool (PET) to assess the end-to-end performance of over 50 legacy IP and SOA applications over radio, wireless, and wireless networks. These networks exhibit significantly more delay and loss and while having much lower bandwidth than terrestrial fiber networks. These limitations can make certain applications inoperable or unusable at the tactical edge. In addition, Stratogis has used the PET tool to access the performance impacts of data center consolidation for the US Navy and DoD contractors. More information ...

Stratogis has worked with OSD and major Defense Aerospace companies to assess the vulnerability of DoD satellite, radio and fiber networks to Anti-Access/Area Denial (A2/AD) attacks. These studies evalualted the impact of jamming, fiber cuts, cyber attacks and ASAT weapons on strategic and tactical networks during major combat operations. These studies have evaluated A2/AD mitigation approaches such as increased EHF protected satellite terminal fielding; satellite disaggregation through the use of small SATS; and the integration of organic airborne communication nodes (ACN) to provide anti-jam beyond line of site communications to ground and naval forces. These studies evaluated the end-to-end network message delivery performance as a function of terminal fielding, and satellite and ACN payload design.

Stratogis worked with a major Defense Aerospace contractor to assess the operational effectiveness of a Joint Integrated Air Missile Defense (IAMD) architecture. Stratogis was responsible for modeling all IAMD network traffic over fiber, microwave, satellite and radio networks. Our models, which included tactical networks such as Wideband Global SATCOM (WGS), WIN-T, Link-16 and Cooperative Engagement Capability (CEC) plus terrestrial fiber networks, was integrated into a large force-on-force engagement model. We evaluated the architecture effectiveness for very large missile engagements for integrated and separate coalition network architectures.

Stratogis has worked with the JTRS Program Office and ASD NII to evaluate JTRS SRW and WNW performance. We have built OPNET models for both waveforms and assessed end-to-end performance and overall network capacity. In addition, we have evaluated the GMR radio effectiveness based on measured data collected at Fort Huachuca. Our NII efforts have evaluated the performance impacts of integrating new JTRS waveforms with WIN-T networks and legacy radio nets. Stratogis has also worked with JTRS manufacturers to assess the impacts of modified HMS, GMR and AMF form factor fielding strategies on operational effectiveness.

Stratogis has worked with CECOM and PM WIN-T to assess the impacts of advanced networking and RF technologies on end-to-end performance and capacity. We developed models for evaluating WIN-T DIFFSERV Quality of Service management strategies based on projected traffic models and equipment performance. Stratogis also evaluated the effectiveness of the NCW bandwidth-on-demand protocols for increasing satellite network capacity. In addition, we developed adaptive coding and modulation technologies for WIN-T satellite terminals and evaluated the link capacity increases achievable in Southwest Asia and Northeast Asia areas of operations.

Stratogis working with ASD NII evaluated Early Infantry Brigade  Combat Team (EIBCT) network performance in urban and tactical operating environments. We evaluated the overall bandwidth requirements and end-to-end network performance of Unmanned Ground Sensors (UGS), Small Unmanned Ground Vehicles (SUGV), and Class I UAVs. We used the NII Scenario Performance Evaluation Tool (SPET) to evaluate the sensor traffic performance over an integrated EIBCT JTRS-WIN-T network.

Stratogis was the modeling and simulation lead for the Lockheed Martin - Northrop Grumman TSAT Team. We developed detailed OPNET simulation models for the TSAT on-board processed payload, the XDR+ waveform and the TSAT terminals. Stratogis worked with the MILSATCOM Joint Program Office (MJPO) and MIT Lincoln Laboratory to develop the TSAT Dynamic Bandwidth Resource Allocation (DBRA) Assessment architecture and traffic model that was used to evaluate the networks' performance effectiveness. Over the course of the program, we performed over 1000 simulations to assess TSAT performance for the DBRA Study and the TSAT System Design Review.
