"WebThe algorithm can be seen as a generalization of the Chandy-Lamport algorithm. It reduces the space complexity of the recorded chan-nel state and permits ﬂexibility in scheduling the po-tentially expensive task of recording local state. The complete algorithm is presented in Section 4.3 and Sec-tion 5 proves that the algorithm is correct. " - Chandy lamport algorithm
