3 Session Overview Microsoft in the Branch Office
Improving WAN efficiency Next Generation TCP/IP Stack SMB 2.0 File System improvements Transparent Caching for SMB Offline Files DFS – Read Only Replica BranchCache™ Differentiating Servers in Branch offices Server Core Active Directory Domain Services – RoDC Partnerships to Offer Windows Services in the Context of WAN Optimization NEW in WS08 R2 NEW in WS08 R2

4 Microsoft in the Branch
Home to 20% of Windows Servers Most servers used as application servers or to provide infrastructure services Branch Office H Q Source Internal Microsoft Research 2007

5 Branch Office Deployment Topologies
Remote Office Appliance Security VPN, Network Access Protection, Identity and Access Networking Data Center + Highly resilient + High Performance - Costs - Complex Distributed Centralized + Ease of Deployment + Simplicity - Performance - Single Point of Failure

6 Why WAN requires special handling
Latency on WAN links Delays connection setup Delays Data Txfer Degrades end user experience Protocols can only Receive limited data based on buffer size LAN Latency < 1ms WAN Latency >100ms

7 Microsoft's Commitment
Improve end user experience through improvements to the underlying protocols Innovate in the Windows Server platform to add features that make it even more suitable for branch deployments Partnerships to offer Windows services in the context of WAN Optimization Controllers 7

8 Network Performance Factors
Sender Application Receiver Application Sender’s Networking Stack Receiver’s Networking Stack Network Make the protocol aware of the varying network conditions Reduce amount of Round trips the protocol makes Reduce WAN utilization

9 Automatically Tune the Network Stack
Automatically adjusts for maximum efficiency Faster network transfers, especially across WAN links Optimized use of available network bandwidth Reduced packet loss resulting in fewer retransmits Optimized performance without loss Intelligent, automated tuning of TCP receive window size Better packet loss resiliency (e.g., wireless connectivity) Advanced congestion control for better throughput (CTCP)

10 TCP Receive Window Size
Windows XP & Windows Server 2003 Default TCP windows size of 64KB NO AUTO TUNING Severely limits round trip times Sender transmits are limited to advertised receive window size Window size backs off by 50% with packet loss Windows size increased slightly with every ACK Manual tuning of receive window size does not offer ideal results Windows Vista/Win7 and Windows Server 2008 and R2 Auto-tune enabled by default Max receive window determined by: Application consumption capacity Network capacity and conditions

11 Redesigned TCP/IP Stack
Winsock User Mode Kernel Mode WSK Clients AFD TDI Clients TDI WSK TDX Next Generation TCP/IP Stack (tcpip.sys) TCP UDP RAW IPv4 IPv6 Windows Filtering Platform API 802.3 WLAN Loop-back IPv4 Tunnel IPv6 Tunnel NDIS Dual-IP layer architecture for native IPv4 and IPv6 support Seamless security through expanded IPsec integration Improved performance via hardware acceleration Network auto-tuning and optimization algorithms Greater extensibility and reliability through rich APIs

12 Server Message Block 2.0 Multiple command in a single packet
Reduced wait time and connection overhead Much larger buffer size Network stack is no longer the bottleneck Application & disk are now the bottleneck Parallel Write, Parallel Response Durable handles allow recover from brief network disruptions Symlink support

13 File Shares – Streaming Improvement
Parallel requests greatly increase read/write speed Request Download speed (kb/sec), 100 ms RTT Response SMB1 SMB2

14 File Copy Comparison 10 MB file over 10 Mbps (50ms) link
Windows 2008 & Vista Throughput (Mbps) Windows 2003 & Vista 03 & XP 08 & XP 9.47 12.91 31.24 32.18 Time to Completion (seconds) The Tolly Group, Inc. (2007)

15 Enhancing the Offline Files experience
Anjli Chaudhry Program Manager – Offline Files Microsoft Corporation

16 Building on Vista SP1 Offline Files
Provides seamless access to network files on File shares whether client is offline or online Common deployment scenarios: Folder Redirection Redirection of “known” client folders (e.g. ‘Documents’) Cached Drives (e.g. H:\ mapped to SMB share) User pinning of remote shares or specific files Publication content for use in branch offices

17 Offline Files – "Usually Offline" Support
Situation Today Windows 7 Solution Full 2-way background synchronization at fixed intervals Synchronization transparent to the end user IT admin can configure synchronization intervals Benefits Folder redirection is a success with online & offline modes in Windows Vista Not transparent to users who are on a high latency network with low throughput Seamless experience for end-users Corporate data is in sync Optimizes the network usage for remote workers & branch offices

18 Transparent Caching Situation Today Windows 7 Solution Benefits
Files accessed on SMB shares are automatically cached to disk Subsequent reads to the file are satisfied from the local cache Caching policy configurable through group policy Transparent to the end user Read response times for files that were just open takes too long Opening a file that was just recently read takes just as long as opening a file for the first time Bandwidth consumption is high regardless of how recent a file was opened Benefits Optimize bandwidth consumption on WAN links Provide near local read response times for end users working over WAN links

28 Why Read-only Replicated folders?

29 ReadOnly DFS Replica Introducing
New in Win7 and WS08R2 Introducing ReadOnly DFS Replica Publication data that should never be changed at branch locations Any open or create requesting WRITE access will be failed by a new filter driver In case the filter is not running, other Win7 Replication Group members will refuse updates from a read-only replication partner

30 End-user experience

31 Microsoft's Commitment
Improve end user experience through improvements to the underlying protocols Innovate in the Windows Server platform to add features that make it even more suitable for branch deployments Partnerships to offer Windows services in the context of WAN optimization Controllers 31

32 Server Core in the Branch
Fewer moving parts Reduced servicing Reduced attack surface Designed for Specific Roles Reduced management overhead Improved availability Smaller System Footprint Less Memory (184 MB idle vs. 309 MB)* Less Disk (1.6 GB vs. 7.6 GB)* *Not recommended minimums

33 What is Server Core? Server Core is a minimal Windows Server 2008 installation option. GUI? – Gone (mostly). Windows Explorer? – Gone. Internet Explorer & Media Player? – Gone. .Net Framework? – Gone. MMC? - Gone too. Designed to support very specific workloads.

34 What can I do with Server Core?
Active Directory Domain Services - ADDS AD LDS (aka, ADAM) Domain Name System Server - DNS DHCP Server File Services Internet Information Services (IIS7) Print Server Windows Media Services Hyper-V .NET Support NEW in WS08 R2
