摘要
提出了用新型的三维网格结构协议来有效地管理分布式系统中的复制的数据。这个协议具有“高可用性”的功能特点,而无需考虑“列”的复制。此技术为分布式系统中的数据复制提供了高效的可能。与现有的三维网格技术比较,该技术具有更高效性和稳定性,且便于分布式数据系统的升级,并通过与现有的三维网格技术的比较结果来加以证明。
Three Dimensional grid structure has numerous applications and is widely studied. A new replica control technique called Enhanced Availability over Three Dimensional Grid Structure Protocol (EA-TDGS) is proposed to manage replicated data in distributed database systems. This protocol provides high availability by imposing a logical structure of modified Three Dimensional Grid Structure (TDGS) protocol without considering copies of columns. The technique provides high availability for write operation by considering only sites that are vertics of EA-TDGS. In comparison to the existing TDGS protocol, it does not only produces higher data availability, but in addition, it is more scalable to the distributed database systems. It is supported by comparison results.
