Joint Network Emulator
The Joint Network Emulator (JNE) project is used to model and develop a wide array of tactical radio technologies that span the joint services of Army, Navy and Airforce under Project Manager Joint Tactical Networks (PMJTN). This program aims to develop and enhance all joint networking waveforms with common network managers. Scalable Network Technologies first developed the project as the JTRS Network Emulator before the official project expired and the company continued its development of radio technologies with PMJTN.〔Project Manager Joint Tactical Networks, Program Executive Office Command Control Communications - Tactical. http://peoc3t.army.mil/jtn/〕
==History==
This program grew out of a Small Business Innovation Research (SBIR) project to design and develop Joint Tactical Radio System (JTRS) waveforms and supporting equipment that was sponsored by the Joint Tactical Networking Center (JTNC) in 2009.〔"Scalable Network Technologies Awarded SBIR Grant to Advance Scalable, Real-Time Analysis Environment for Military Networks." Computer User. http://www.computeruser.com/scalable-network-technologies-awarded-sbir-grant-to-advance-scalable-real-time-analysis-environment-for-military-networks.html〕 JTRS is an attempt to network multiple weapon system platforms and forward combat units so that different branches of domestic and allied forces, as well as their respective civilian counterparts, can always depend on intra- and inter-service communications even in dynamic environments such as disaster areas. The JTRS specifications use software-defined radios to cover dozens of waveforms so as to connect with the vast array of “legacy” radios still used by the many different services in order to ultimately transition from the many “legacy” communications systems to JTRS-based equipment. However, given that such a switch takes time, economics, and logistics, the army contracted Scalable to find a way in which impacted parties could engage in planning, testing and training with the JTRS-based equipment with a simulation.〔Joint Network Emulator (JNE). Scalable Network Technologies. http://web.scalable-networks.com/content/joint-network-emulator-jne〕 In 2011, the Joint Program Executive Office, Joint Tactical Radio System (JPEO JTRS) awarded SCALABLE a SBIR phase III contract with an estimated value of $11 million to transition the research into an operational product to be deployed throughout the DoD.〔"Army Network Test to Include Virtual Extension." Defense Systems: Knowledge Technologies and Net-Enabled Warfare. http://defensesystems.com/articles/2011/06/08/c4isr-1-jtrs-sidebar-software-tool.aspx〕 The funding has since expired, but the JNE project has continued as a program to develop and model radio technologies for all branches of the military under PMJTN.
