Branch Office: 5 Ways Server 2008 Improves WAN Utilization.
Bandwidth utilization, latency, and the reliability of the Wide Area Network are three major concerns when administering a branch office environment. Windows Server 2008 helps to address these concerns through the following 5 technologies.
- New XML-based format for policy-definition files called ADMX in Windows Server 2008 addresses policy file replication issues.
- The ADMX format supports a central store for information relating to all policies. Specific Group Policy Object (GPO) settings associated with previous policy-definition file formats are no longer replicated as a result.
- SMB 2.0
- SMB 2.0 protocol enhances communication by:
- :Multiple SMB commands within the same packet. This reduces the number of packets sent between an SMB client and server, which was a common complaint against SMB 1.0
- Larger buffer sizes compared to SMB 1.0.
- Larger number of concurrent open file handles on the server.
- Larger number of file shares for a server.
- Durable handles that can withstand short interruptions in network availability.
- Next Generation TCP/IP stack
- The Next Generation TCP/IP stack optimized for use in the variety of networking environments that exist today. Branch office environments benefit from enhancements to performance, connectivity, and reliability. The new TCP/IP stack includes or enhances:
- Receive Window Auto-Tuning
- Compound TCP
- Enhancements for high-loss environments
- Neighbor Unreachability Detection for IPv4
- Changes in dead gateway detection
- Changes to path maximum transmission unit (PMTU) black hole router detection
- Routing compartments
- Network Diagnostics Framework support
- Windows Filtering Platform (WFP)
- Explicit Congestion Notification (ECN)
- Adopts all of the changes made in Windows Server 2003 R2 including:
- New state-based, multimaster replication, which is optimized for WAN environments and which supports replication scheduling, bandwidth throttling, and a new byte-level compression algorithm known as remote differential compression (RDC).
- DFS namespaces, which help administrators group shared folders that are located on different servers. The shares can then be presented to users as a virtual tree of folders.
- Read-only DFS, which enables members to access data without the ability to change it.
