摘要
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。结合分布式事务时效期要求,描述了并行分层式链路2PC协议及其正确性准则;给出了P2L2PC协议执行的基本处理过程并证明了其正确性;同时对并行分层式链路2PC协议进行了性能评价和比较。
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. Taking into account the time limit, the basic idea of the P2L2PC protocol and its correctness criteria, are described. The basic executive process of the P2L2PC protocol is presented, and its correctness is proved. Performance of the parallel layered link 2PC protocol is evaluated and compared with other protocols.
