在分布式数据库领域，分布式数据更新是极其重要的研究课题，因为数据更新操作必须满足数据库的完整性、一致性、可靠性和稳定性要求。

In the development process of DDBS, the link of among sites is diversified. In view of this fact, the parallel layered link is studied and the parallel layered link 2PC ( P2L2PC) protocol is put forward.

针对分布式数据库系统发展过程中站点连接链路的多样性，研究了并行分层式连接结构，并在并行分层式连接结构基础上，提出了并行分层式链路2PC（P2L2PC）协议。

( b) Now, many DDBS protocol have been researched, but these protocol adopted basically "one vote one-off veto" of voting means.
