| Abstract: | 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. |
