Disparate customer support centers in an enterprise system apply different monitoring and analysis tools while attempting to ensure quality of service for the end-user. These provide inconsistent metrics that make problem resolution inefficient reactive rather than proactive effective. A systems engineering approach is proposed considers high-speed communications done by via collaboration isolation. This paper presents graphical representations various aspects include architectural,...
Faced with intense competition, network service providers, supported by their respective operations centers (NOCs), must ensure the best possible quality of (QoS) and corresponding experience (QoE) for end-users or face loss business. QoE represents perception experienced a real-time system, such as VoIP. The challenge becomes significant when applications running on net-centric enterprise systems, driven methodologies oriented architecture (SOA), encounter issues that require time-sensitive...
Department of Defense (DoD) intelligence, surveillance, and reconnaissance (ISR) assets; including manned unmanned airborne, space-borne, maritime, terrestrial systems; play critical roles in support current future military operations. However, services defense agencies face an ever growing challenge effectively processing, exploiting, disseminating ISR data from multiple, diverse senor platforms for end-users who collaborate share information within a net-centric enterprise environment....
Manpower is driving up DoD costs while budgets are shrinking; therefore the customer seeks a solution to enable increased mission capacity along with staff reductions. One way accomplish this through an autonomous capability support end-to-end activities. The Mission Information Autonomous Intelligent Decision Engine (MiAide) approach for meeting objective create system of systems (SoS) that work together automation tasks previously done by humans. MiAide built upon novel, but...
