Abstract
Techniques are described for resynchronizing mutually shared data stored on network devices of a computer network. Upon receiving change instruction and globally unique identifier (GUID) messages, each of the network devices records the change instructions and GUIDs in a journal of the network device. When communication is lost for a period of time between a first network device and a second network device, the mutually shared data of the first network device may need to be resynchronized with the mutually shared data of the second network device. The techniques described herein allow resynchronization of the mutually shared data of the first network device based on a common GUID recorded in the journals of both first and second network devices, the journal of the first network device, and the journal of the second network device.
