Windows Server 2008 許多用途,包括路由複寫、 client 相關性、 系統磁碟區 (SYSVOL) 複寫、 散發檔案系統命名空間 (DFSN),以及位置服務使用資訊的網站。Windows Server 2008 uses site information for many purposes, including routing replication, client affinity, system volume (SYSVOL) replication, Distributed File System Namespaces (DFSN), and service location.

尚複寫Routing replication

Active Directory Domain Services (AD DS) 使用多主機、 儲存轉送複寫的方法。Active Directory Domain Services (AD DS) uses a multimaster, store-and-forward method of replication. 網域控制站通訊的第二個網域控制站,然後通訊第三方,等等,以之前所有網域控制站都收到變更 directory 變更。A domain controller communicates directory changes to a second domain controller, which then communicates to a third, and so on, until all domain controllers have received the change. 若要達到最佳平衡縮短複寫延遲和降低流量,台拓撲控制複寫 Active Directory 區分在網站中發生的複製和複寫的網站。To achieve the best balance between reducing replication latency and reducing traffic, site topology controls Active Directory replication by distinguishing between replication that occurs within a site and replication that occurs between sites.

在網站中複寫最適合︰ 複寫 speeddata 更新觸發程序,並資料傳送不資料壓縮所需的費用。Within sites, replication is optimized for speeddata updates trigger replication, and the data is sent without the overhead required by data compression. 反而,之間網站複寫壓縮透過寬區域 (wan) 連結減少的據傳輸費用。Conversely, replication between sites is compressed to minimize the cost of transmission over wide area network (WAN) links. 之間網站複寫時,每個網域在每個網站單一網域控制站會收集 directory 變更會儲存並傳送另一個網站的網域控制站排程的時間。When replication occurs between sites, a single domain controller per domain at each site collects and stores the directory changes and communicates them at a scheduled time to a domain controller in another site.

Client 相關性Client affinity

網域控制站使用通知 Active Directory 戶端網域控制站出現在接近網站的相關資訊的網站。Domain controllers use site information to inform Active Directory clients about domain controllers present within the closest site as the client. 例如,請考慮 client 西雅圖網站,並不知道其網站聯盟連絡人網域控制站的亞特蘭大網站中。For example, consider a client in the Seattle site that does not know its site affiliation and contacts a domain controller from the Atlanta site. 根據 client 的 IP 位址,網域控制站亞特蘭大判斷 client 實際上是來自和網站會將資訊傳送到 client 的網站。Based on the IP address of the client, the domain controller in Atlanta determines which site the client is actually from and sends the site information back to the client. 網域控制站也會通知 client 選擇的網域控制站是否是最近一它。The domain controller also informs the client whether the chosen domain controller is the closest one to it. Client 快取提供查詢的特定網站服務 (SRV) 資源筆 (網域名稱系統 」 (DNS) 資源的記錄用來尋找網域控制站 AD ds),亞特蘭大網域控制站的網站資訊,並藉此會尋找網域控制站在相同的網站。The client caches the site information provided by the domain controller in Atlanta, queries for the site-specific service (SRV) resource record (a Domain Name System (DNS) resource record used to locate domain controllers for AD DS) and thereby finds a domain controller within the same site.

尋找網域控制站在相同的網站,來 client 可透過 WAN 連結避免通訊。By finding a domain controller in the same site, the client avoids communications over WAN links. 如果不網域控制站位於 client 網站,網域控制站的其他連接網站和目的地的相對的最低成本連接通知 (暫存特定網站服務 (SRV) 資源記錄器 dns) 本身網域控制站不具有網站中。If no domain controllers are located at the client site, a domain controller that has the lowest cost connections relative to other connected sites advertises itself (registers a site-specific service (SRV) resource record in DNS) in the site that does not have a domain controller. 發行 dns 網域控制站是從接近網站的網站拓撲所定義。The domain controllers that are published in DNS are those from the closest site as defined by the site topology. 此程序可以確保每個網站的已驗證的慣用的網域控制站。This process ensures that every site has a preferred domain controller for authentication.

尋找網域控制站的處理程序的相關詳細資訊,會看到 Active Directory 集合 (http://go.microsoft.com/fwlink/?LinkID=88626)。For more information about the process of locating a domain controller, see Active Directory Collection (http://go.microsoft.com/fwlink/?LinkID=88626).

SYSVOL 複寫SYSVOL replication

SYSVOL 是一組資料夾集合位於網域中的每個網域控制站檔案系統。SYSVOL is a collection of folders in the file system that exists on each domain controller in a domain. SYSVOL 資料夾提供必須複寫網域,包括群組原則物件 (Gpo)、 開機和關機及登入及登出指令碼的檔案的預設 Active Directory 位置。The SYSVOL folders provide a default Active Directory location for files that must be replicated throughout a domain, including Group Policy objects (GPOs), startup and shutdown scripts, and logon and logoff scripts. Windows Server 2008 可以使用的檔案複製服務 (FRS) 或散發檔案系統複寫 (DFSR) 複寫 SYSVOL 資料夾的一個其他網域控制站的網域控制站所做的變更。Windows Server 2008 can use the File Replication Service (FRS) or Distributed File System Replication (DFSR) to replicate changes made to the SYSVOL folders from one domain controller to other domain controllers. FRS 與 DFSR 複寫根據您在網站拓撲設計建立排程這些變更。FRS and DFSR replicate these changes according to the schedule that you create during your site topology design.

DFSNDFSN

DFSN 直接 client 伺服器裝載要求在網站中的資料用於資訊的網站。DFSN uses site information to direct a client to the server that is hosting the requested data within the site. 如果 DFSN 相同網站中找不到資料的複本,DFSN 使用網站中的資訊以判斷您的檔案伺服器的 DFSN 共用資料 AD DS 是最近的。If DFSN does not find a copy of the data within the same site as the client, DFSN uses the site information in AD DS to determine which file server that has DFSN shared data is closest to the client.

位置服務Service location

發表服務,例如檔案和和列印服務中 AD DS,您可以允許 Active Directory 戶端以尋找最近的網站或中相同所要求的服務。By publishing services such as file and print services in AD DS, you allow Active Directory clients to locate the requested service within the same or nearest site. 列印服務會使用儲存在 AD DS 位置屬性,讓瀏覽,位置,而不知道其允許使用準確位置的使用者。Print services use the location attribute stored in AD DS to let users browse for printers by location without knowing their precise location. 如需有關設計和部署列印伺服器,查看設計和部署列印伺服器 (http://go.microsoft.com/fwlink/?LinkId=107041)。For more information about designing and deploying print servers, see Designing and Deploying Print Servers (http://go.microsoft.com/fwlink/?LinkId=107041).
