PREVENTING CONFLICTS IN DISTRIBUTED SYSTEMS |
摘要 |
A token-based protocol used to prevent conflicts between copies of the same data items residing in different servers of a replicated distributed system is provided. The servers in the system with database replicas are provided with token pointers that are each associated with a token. Token pointers are used to track the current possessor of the token. Whenever a server receives or transfers a token, its corresponding token pointer is updated to reflect which server possesses the token. The use of token pointers advantageously eliminates the need for global cooperation by the servers to regenerate a lost token.
