Method for coordinating membership with asymmetric safety in a distributed system |
摘要 |
A method is disclosed for coordinating membership subject to an asymmetric safety condition from multiple processes in a distributed system. Each is callable by a distributed application for system status or for executing tasks of the application. Initially, each process sends the other processes its view on their status, where the view includes the names of a group of the processes. It then waits for similar views from other processors except those regarded as failed in its own view, up to a predetermined timeout. Each process then generates a resulting view by intersecting its local view with the names of those processes from which it has received views. The local views are updated based on the resulting views and again exchanged until a termination condition occurs.
