In this case, subsequence instances of the basic Paxos protocol (represented by I+1) use the same leader, so the phase 1 (of these subsequent instances of the basic Paxos protocol), which consist in the Prepare and Promise sub-phases, is skipped.
在这种情况下，Basic Paxos的后续实例(由I+1表示)使用相同的Leader，因此，包含在Prepare和Promise的阶段1(Basic Paxos协议的这些后续实例)将被跳过。
