The Chandy–Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. It was developed by and named after Leslie Lamport and K. Mani Chandy.

Through an algorithm that has simply become known as the ‘Chandy-Lamport’ algorithm, Chandy & Lamport show us that it is indeed possible (dare I even say easy?) to take a distributed snapshot of a distributed system, and that this can be a very useful thing indeed. The Chandy—Lamport algorithm is a snapshot algorithm that is used in distributed systems for recording a consistent global state of an asynchronous system. Believe it or not, while I was struggling through this question, I sent an algorthm to Dr. The Chandy-Lamport algorithm uses a control message, called a marker whose role in.
