Chandy-lamport算法详解
Web3 The Chandy-Lamport Algorithm This section presents the Chandy-Lamport algorithm for determining global states of distributed systems. The algorithm works as follows: Each process records its own state and the two processes on which a chan-nel is incident cooperate in recording the channel state. The algorithm cannot ensure that the states of ...
