一个排队网络模型来分析分布式数据库测试床系统的性能，并针对经验测量进行验证。该模型包括并发控制协议（带有分布式僵局检测的两相锁定），交易恢复协议（前图之前的书面遗留）以及使用的提交协议（集中式两阶段提交）的效果测试床系统。排队模型在三个主要方面与以前的分析模型不同。首先，它是分布式交易处理系统的模型。其次，它比以前的分析模型更通用和整合。最后，它反映了功能运行的分布式数据库测试床系统，并根据性能测量得到了验证。
A queueing network model to analyze the performance of a distributed database testbed system is developed and validated against empirical measurements. The model includes the effects of the concurrency control protocol (two-phase locking with distributed deadlock detection), the transaction recovery protocol (write-ahead-logging of before-images), and the commit protocol (centralized two-phase commit) used in the testbed system. The queueing model differs from previous analytical models in three major aspects. First, it is a model for a distributed transaction processing system. Second, it is more general and integrated than previous analytical models. Finally, it reflects a functioning distributed database testbed system and is validated against performance measurements.
