  3. Apps Users Businesses Run on Applications

  4. Global Market Forces Driving Change User Experience Declining IT Responsiveness Declining

  5. Users Apps Traditional Application Deployment More Bandwidth Fastest Network Lock Down& Standardize Best andMost Servers Best PCs • “Managed Desktops” Costly • Poor User Experience • Apps Still Slow • Data Still Vulnerable

  6. Application DeliveryInfrastructure NetworkInfrastructure ServerInfrastructure DeviceInfrastructure StorageInfrastructure Apps Users Greater ROI from Existing Investments

  7. Users Apps App Delivery as an On-Demand Service Optimize Secure Control Monitor • Lowest Total Cost • Best User Experience • Fastest Performance • Highest Security

  9. Powering the World’s Most Popular Web Applications 75% Of Internet Users

  10. Emerging Leadership in Enterprise Web Applications 7000+ Deployments Worldwide

  11. Web Protocols Extremely “Chatty” Remote Users Further Away from Apps Apps Moved into Fewer Centralized Datacenters Increased Security Requirements Web Application Delivery Challenges

  12. Growing Importance of the Branch 55 % employees are remote Market trends: Business process outsourcing Globalization Worker mobility

  13. The Long Distance Problem LAN WAN Throughput AverageUtilization AverageUtilization Time Slow Start Slow Ramp • Contributing factors to poor performance • Latency • Congestion • Small transmission window size

  14. Traditional Approaches Branch Office Experiences Slow Application Response Time Upgrade to More Bandwidth Branch Office Headquarters Data Center Result: Expensive · Applications Still Slow ·Doesn’t Scale

  15. What Causes Poor Application Performance over the WAN? Network latency (distance) The greater the distance, the worse the application performs Bandwidth utilization drops exponentially as distance increases Accessing E-mail in Seattle from a server in Orlando can take up to 80 times longer than from a server in the same building! San Francisco to Los Angeles San Francisco to Chicago San Francisco to Miami In the same city

  16. Symmetric vs. Asymmetric

  17. SSL Acceleration Compression Caching Security Web App Delivery Challenges at the DC Web Servers Application Servers DB Servers Chatty Protocols, Long Hauls,High Latency Variety of Point Products Servers AddUp Quickly

  18. SSL Acceleration Compression Caching Security Citrix NetScaler Web Servers Application Servers DB Servers Reduces Bandwidth Required Reduces Load on Backend Servers Eliminates Multiple Inefficient Point Products

  19. Accelerate End-User Performance &Improve Server Efficiency LAN • Advanced TCP Optimization • TCP Multiplexing and Buffering • AppCache • AppCompress • SSL Offload Branch Application Infrastructure Mobile User

  20. Ensure Maximum Application Availability LAN • Load Balancing • Content Switching • Rewriting and Redirection • Surge Protection Branch Application Infrastructure Mobile User

  21. Enhance Application Security Prevent information theft and leakage LAN • Application layer protections • DoS Mitigations • Content filtering and redirection Branch Application Infrastructure Mobile User

  24. NetScaler: Simplify Web Application Delivery Eliminate application downtime Increase performance by 5x Block 100% of web attacks Improve web server utilization by 60% Address Web 2.0 and other emerging challenges

  25. Application Optimization on the WAN The Symmetric Solution

  26. Symmetric vs. Asymmetric

  27. Traditional Approaches Branch Office Experiences Slow Application Response Time Upgrade to More Bandwidth Branch Office Headquarters Data Center Result: Expensive · Applications Still Slow ·Doesn’t Scale

  28. The Citrix Repeater Solution Maintain/Reduce the Current Bandwidth Communicate with More Branch Offices Support More Users Extend Performance to Mobile Users Headquarters Data Center Branch Office Mobile Users Result:Cost-Effective Simple Scales

  29. Citrix Repeater Solution Headquarters Branch Repeater Repeater • A symmetric, network acceleration solution • A site-to-site appliance and software, for datacenters, hub sites, remote offices, home or mobile users. • An instance of Repeater required at each location • Accelerates Data over WAN links • Transparent Device • TCP Flow Control Acceleration • Multi-Level Data Compression: Adaptive, Toeknized • Protocol Acceleration: CIFS, ICA

  30. Repeater is Transparent IDS • No network reconfiguration • Lowers deployment and maintenance costs Repeater Repeater Datacenter Branch Office Users

  31. Adaptive Compression • Not a “one size fits all” solution Very Efficient Compression Not the right compression algorithm! Try Another! Maximum Reduction = Faster applications

  32. Multi-Level Compression: Tokenization • Not a “one size fits all” solution Bandwidth Savings

  33. Application AccelerationExample: CIFS I want to open a file Which file? \\dog\bone\blue Who are you? John Whomever Password? “Whatever” OK, It’s open! 250ms 250ms 250ms 250ms 1000 ms 125ms WAN Latency

  34. Application Acceleration Example: CIFS I want to open a file I want to open a file Which file? Which file? 1 ms \\dog\bone\blue \\dog\bone\blue OK, It’s open! OK, It’s open! Who are you? Who are you? 125 ms John Whomever John Whomever 1 ms Password? Password? 125 ms “Whatever” “Whatever” WAN Open \\dog\bone\bluefor John Whomever,password “Whatever” 252 ms

  35. Application AccelerationRepeater CIFS Performance Application Response Time Improvement

  36. Citrix Repeater Client Delivers WAN Optimization to home-based, mobile and small office users Supports any WAN connection Residential broadband WiFi hotspots Cellular data services Interoperates with leading VPN solutions including Citrix Access Gateway Standard and Advanced Editions

  37. First PassCustomer Eval Before: 2 min 17 sec After: 23 seconds!

  38. Repeater Accelerates Apps over WAN • Adaptive TCP Flow Control • Utilizes the entire the WAN pipe • Mitigates TCP penalties • Multi-Level Compression • Applies the optimal combination of compression algorithms for the WAN speed, traffic type, and link conditions • Not a “one size fits all” solution • Protocol and Application Acceleration • Streamlines chatty protocols for better performance • CIFS, NFS, HTTP, FTP, ICA

  39. What about Terminal Services, WISP, and ICA?

  41. Proven SharePoint Benefits

  42. Citrix Repeater Appliance Citrix Repeater Appliance Test Configuration Headquarters Branch Tested Connections Defined: Connection Nickname Connection Latency Packet Loss Regional to HQ 44.0 Mbps 90 ms 0.1% Branch WAN 6.0 Mbps 90 ms 0.1% US to EMEA 6.0 Mbps 200 ms 0.1% US to APAC 1.5 Mbps 300 ms 1.0% Satellite 6.0 Mbps 300 ms 0.1% • Citrix NetScaler 10000 Application Delivery Switch, Version 7.0 • Citrix Repeater 8800 @ Central Site, and 8500 @ Branch location. Version 3.1.7 • Windows Server 2003, Internet Explorer 7.0 client • Microsoft Office SharePoint Server 2007 • Server Specifications: Dual Intel Xeon 3.6 Ghz, 4GB RAM • Apposite Linktrophy for WAN Simulation • Test scripts provided and managed by Microsoft SharePoint performance testing team

  43. Response Time in Seconds Common SharePoint Portal Server Tasks 3.5X faster! • All routine SharePoint tasks are accelerated with the addition of Citrix NetScalerand Repeater • MySitepages load 74% faster • File downloads improved between 33% and 87% as file size increased • As user’s connections get worse (remote, satellite, etc), performance remains consistently fast • Previously unusable scenarios suddenly become high performance! • What would take 10+ minutes without Citrix now happens in about 10 seconds Up to 8X Better! 5Mbps, 300ms

  44. High Speed WAN Performance Boost File Download Response Time (Sec) • 12MB File Downloads that used to take 23 seconds were reduced to 1/10th of a second! • Citrix RepeaterMulti-level compression and adaptive flow control make file access fast and seamless for SharePoint users 230X FASTER 44 Mbps, 90ms latency, .1% loss

  45. SharePoint - High Latency Scenarios • Low bandwidth, high latency, and packet loss all contribute to poor user experience • Citrix Repeaterremoves those barriers by managing data transmission and optimizing performance for connectivity challenges • Being “connected” doesn’t equate to being “productive” From 68 sec to 1/10th sec! 6 Mbps, 300ms latency, 0.1% packet loss

  46. Key Takeaways NetScaler and Repeater • Citrix NetScaler speeds apps up to 5x faster, and ensures availability, acceleration, and security of user applications. • Repeateroffers proven bandwidth and protocol optimizations for the best user experience, with compression ratios and transparency that help save bandwidth, deployment and management costs. • Thoroughly validated with SharePoint for improving performance
