English to Russian Tech/Engineering Computers: Systems, Networks Active Directory

Контекст:

One of the biggest differences between Active Directory and NT 4.0 is the introduction of multimaster domain controllers. This is to say that domain controllers all contain read/write copies of the account data. In NT 4.0, only the Primary domain controller was able to write to the SAM database. This meant that all Backup Domain Controllers had to get their SAM updates directly from the PDC. This hub and spoke replication resulted in large amounts of traffic, much of which had multiple conversations going across the same WAN connection. In Windows 2000 and 2003 Active Directory, domain controllers are able to determine their own replication topology and create meshed replication paths to make replication as efficient as possible. Rather then have all DCs in a site talk to the same DC for replication, a bridgehead server can replicate with a remote server and then replicate the same information locally among other domain controllers in the same site. This results in a significant decrease in domain controller replication traffic.
