An Improved Two-phase Commit Protocol Adapted to the Distributed Real-time Transactions
2012
Based on the existing
two-phase commit protocol(2PC), this paper proposes a protocol adapted to the distributed real-time transaction commit, which can avoid the blocking problem when dealing with transactions by coordinator redundancy; additionally, by the "health loan" of the locked data, the concurrency of transaction implementation is expanded to save the waiting time. Experimental analysis shows that: when the average arrival interval time of transaction is small, the success rate of the improved commit protocol is significantly higher than that of 2PC. Streszczenie. W artykule zaproponowano protokol bazujący na dwufazowym protokole typu 2PC. Nowy protokol pozwala na oszczednośc czasu oczekiwania - jeśli średni czas odstepu miedzy transakcjami jest maly przeplywnośc danych jest wyzsza niz w klasycznym protokole 2PC. (Ulepszony dwufazowy protokol do zarządzania transakcjami w czasie rzeczywistym)
