Objectives: The main objectives of this research include:

  • Research, review and assess the applicability of the Communications Effects Server (CES) modeling environment as a research platform for model based architecture assessment. This work should also include the extensibility of the CES for other classes of systems beyond those currently modeled.
  • Its applicability to a model based architecting environment, to allow rapid architectural assessment from an end-to-end systems performance perspective.
  • Make recommendations for further verification and validation of the network centric architecture (performance) modeling environment, CES.
  • Understand the quality of the models and the modeling approach to allow extensibility to assessing the PEO-I BCT-M (or similar) architecture from a number of additional perspectives such as network reliability and dependability, network resilience, and security.

Approach: This task will establish a systems architecture modeling and assessment (SAMA) environment within the SER-UARC, with the Army’s CES (communications effects server) modeling tool as a key component. While this tool was originally intended to assess network centric system performance, this research will investigate applying the tool to architecture assessment prior to putting the system in the field. It will explore the key performance parameters for the assessment of system architecture individually, then extend that to the assessment of the SoS and a network centric SoS. It will be approached in two phases. Phase 1 will establish the capability, and deliver an architecture description document to guide further extensions to the capability. Additionally, a research roadmap for Phase 2 will be completed as part of Phase 1.

Significant Research Findings & Products:
CES is a highly specific product that does not lend itself to higher level abstractions. The documentation is at the code level of detail (programmers manuals) and it would take an experienced programmer months to learn the codebase to extend this product for communication system architecting. Each of the waveforms requires a high level of detail that would not be available when architecting the system. All this coupled with the high cost of the core license makes this a very expensive product for system architecting.
