The Distributed File System role service consists of two child role services: If you are not familiar with DFS Namespaces and DFS Replication in Windows Server 2008, we recommend that you read the document titled "Overview of the Distributed File System Solution in Microsoft Windows Server 2003 R2" on the Microsoft Web site ( The overview describes the benefits of DFS Replication and the improvements it offers over File Replication Service (FRS).For information about the enhancements of DFS introduced in Windows Server 2008, see "Distributed File System" on the Microsoft Web site ( For information about DFS in Windows Server® 2008 R2, see the What's New in Distributed File System topic in Changes in Functionality from Windows Server 2008 to Windows Server 2008 R2.For a list of recent changes to this topic, see the Change History section of this topic.
Under each namespace is a hierarchical view of folders.
Folders that have targets use a special icon to differentiate them from folders that do not have targets.
The contents of the details pane change according to what you have selected in the console tree.
For example, if you select a namespace in the console tree, you see tabs named Namespace, Namespace Servers, Delegation, and Search in the details pane.
To use all functionality of DFS Namespaces, your environment must meet the following minimum requirements: For information about the minimum requirements to use DFS Namespaces, see Prepare to Deploy DFS Namespaces; for information about the minimum requirements to use DFS Replication, see Review Requirements for DFS Replication.
During Setup, follow the on-screen prompts to install Windows Server 2008.
Optical burst switching (OBS) is proposed as suitable switching architectures for directly transporting traffic over a bufferless wavelength division multiplexing (WDM) networks.
Parallel optical burst switching (POBS) is a variant of the OBS model that takes this concept further by transmitting data bursts wavelength and time dimensions.
However, there is a lack of simulator that simulates POBS networks.
This paper presents an update to the conventional OBS model in the NCTUns-6.0 simulator ( tool is capable of simulating POBS networks for ultra-dense WDM.
The Distributed File System (DFS) technologies offer wide area network (WAN)-friendly replication as well as simplified, highly available access to geographically dispersed files.
