This paper presents an algorithm for global state detection based on peer-to-peer interactions. The interactions in distributed systems can be analyzed in terms of the peer-to-peer pairwise interactions of intervals between processes. This paper examines the problem: “If a global state of interest to an application is specified in terms of the pairwise interaction types between each pair of peer processes, how can such a global state be detected?” Devising an efficient algorithm is a challenge because of the overhead of having to track the intervals at different processes. We devise a distributed on-line algorithm to efficiently manage the distributed data structures and solve this problem. We prove the correctness of the algorithm and analyze its complexity.
