Autonomous, Collaborative Control for Resilient Cyber Defense (ACCORD)

Abstract. ACCORD addresses the need for robust, rapidly adaptive resource allocation mechanisms in cloud computing. It employs a distributed, game-theoretic approach to apportion computational loads in an efficient, prioritized, Pareto-optimal fashion among geographically dispersed cloud computing infrastructure. This paper describes ACCORD algorithms, software implementation, and initial experimental results. Our results illustrate how a distributed, ACCORD-enabled cloud architecture autonomously adapts to the loss of computing resources (e.g., due to failures, poor network connectivity, or cyber attack) while ensuring that users receive maximal, prioritized utility from available cloud resources.
