我们要讨论的第一个复制元数据项目是更新序列号(usn)。
The first item of replication metadata we'll discuss is the Update Sequence Number (USN).
两种类型的写入操作都可增加域控制器上的更新序列号，这意味着每当从其他DC复制了更改时，该序列号都会增加。
The Update Sequence Number on a domain controller is incremented by both types of write operations, which means that it is incremented whenever changes are replicated in from another DC.
在使用基于P8的分发器对象时，获取序列号的方法在本质上是一样的：读取旧值、更新并储存新值，然后将新值返回给调用方。
When using a P8-based dispenser object, the conceptual idea for getting a sequence number is the same: read the old value, update and store the new value, and return the new value to the caller.
如果接收方的数据已发生具有更高序列号(或更新的时间戳)的更改，则较早的更改可能会被拒绝。
If the data at the receiving end has been modified by a change with a higher sequence number (or later timestamp), then the earlier change may be rejected.
除了某人请求新的序列号之外，CE服务器还在每次更新持久化对象之后都将USN增加 1。
The CE server increments the USN whenever the persisted object is updated, not just when someone has requested a new sequence number.
该文针对AODV协议中的虚假目的序列号攻击以及已有解决方案中的缺陷，引入信誉值更新算法，设计一种基于AODV的入侵识别协议。
This paper analyzes current solutions and proposes a protocol to solve false destination sequence attack in AODV by introducing an algorithm of reputation rating updating.
此方法成功完成时，基序列号已更新。
When this method successfully completes, the base sequence number has been updated.
