The Communication, Frameworks, and Infrastructure (CFI) forum focuses on technologies that support interoperation and run-time execution of distributed simulations. Historical examples include the HLA Run-Time Infrastructure (RTI), DIS, ALSP, and SPEEDES. The Forum will also consider new and alternate infrastructure concepts, such as web-based technologies. Topics include performance data, implementation and design details, usage strategies, networking techniques, fault tolerance, security considerations, and middleware or other frameworks for constructing, utilizing, or extending simulation infrastructure.
