Crisscross cancellation protocol |
摘要 |
Technologies, systems, and methods for ordered message delivery that avoid message races or crisscrosses between communicating nodes. For example, if Node A sends message 3 towards Node B and, shortly thereafter, Node B sends message X to Node A. Node A would like to know whether or not message X reflects Node B's state after receiving message 3. If Node B received message 3 prior to sending message X, then proper state may be maintained between the nodes. But if messages 3 and X crisscrossed, or if message 3 was never properly received by Node B, then the state between the nodes may be corrupt. Technologies, systems, and methods are provided to avoid such corruption. |

1. A method performed on a computing device, the method comprising sending a message that comprises a set of variables including a nonce state variable configured for identifying a current session of the computing device, a counter state variable configured for indicating a last message sent by the computing device to a remote computing device, a remote nonce state variable configured for identifying a current session of the remote computing device as known by the computing device, and a remote counter state variable configured for indicating a last valid message received by the computing device from the remote computing device, the set of variables configured for use in detecting a message race condition. |
