  1. Visibility – acceleration - security Harri Kurronen 3. June, 2009

  2. Blue Coat Solutions

  3. Visibility 3

  4. Tools Deployed Are Not Good Enough Not Smart Enough • No application view (network based) • Big problems avoid detection/resolution New Demands: Voice, Video • Newly added to converged MPLS networks • VERY performance sensitive, no tools deployed Reactive • End user complaints No Ability to Fix • How do you resolve issues? 4

  5. Blue Coat Visibility – Overcome Limits Classification Voice Quality Proactive Response Time Monitoring Fix Problems • Layer 7+ Autodiscovers 600+ Applications • Find elusive recreation: iTunes, YouTube, etc. • Break down compound Enterprise apps: SAP, Oracle, Citrix • Real traffic, in real time for voice and video conf (RTP) • Quality (MOS, rFactor) and Utilization (peak & average) • Jitter, delay, loss • Apply Powerful QOS & Compression - RESOLVE • Contain recreation, protect mission critical • Integrate with acceleration devices like ProxySG • Track end user experience – network delay, server delay • Set baselines and exception thresholds • Alert, alarm & integrate: SNMP, XML, Email Not Smart Enough New Demands: Voice, Video Reactive No Ability to Fix Application View, Fix Problems & Deliver ROI 5

  6. PacketShaper Key Functionality Application Visibility Application QoS RAM-Based Compression Key Solutions Visibility & Performance Monitoring Recreation Traffic Control Delivery/Acceleration of Real Time Applications Voice/IPT Video Conferencing Thin Client/Virtual Desktop Transactions 6

  7. Classification: Basis of Control Classification Management Metrics Usage RTM VoIP Diagnostics • Discover Applications on Network • Find Elusive P2P, YouTube, iTunes, etc • Break down Oracle, SAP, Citrix, Microsoft • Align Class Tree to Business • Track business processes – end user response • Monitor SLAs – carrier, internal app • Monitor utilization/budget per application • Limit recreation

  8. Application Based Utilization & Metrics Classification Management Metrics Usage RTM VoIP Diagnostics Customer Sees 60% of WAN is Recreational Top Applications, Users Where is WAN Budget spent? Real Time Troubleshooting Long Term Capacity Planning

  9. Response Times: Measure Transactions End-user experience Network & Server Delay Thresholds for SLA Alert, alarm, integrate Classification Management Metrics Usage RTM VoIP Diagnostics Total Delay SAP Order Entry: 1220 ms Network Delay: 340 ms Server Delay: 880 ms

  10. Voice Metrics: Real Traffic, Real Time Classification Management Metrics Usage RTM VoIP Diagnostics • For Real Time Protocol (RTP) Voice Video Conferencing • Call Volume • Network Metrics Loss Latency Jitter • Quality Mean Opinion Score (MOS) rFactor

  11. Troubleshooting Diagnostics Classification Management Metrics Usage RTM VoIP Diagnostics Host Analysis – Real time host/IP address view (below) TCP Health – Connection state (good, aborted, refused, ignored) PacketCapture – Targeted Capture TCPDump format Synthetic Transactions – HTTP/S, FTP, SMTP, Echo & Custom 11

  12. Central Management: IntelligenceCenter Classification Management Metrics Usage RTM VoIP Diagnostics IntelligenceCenter • Centralized Reporting Collection (flows or ME) Correlation Reporting & Alarms • SLA Dashboard (left) Quick summary app performance • Different Roles & Views Per app Per site Customized portals 12

  13. Acceleration 13

  14. Bandwidth Management Protocol Optimization Object Caching Byte Caching Compression File Services (CIFS), Web (HTTP), Exchange (MAPI), Video/Streaming (RTSP, MMS), Secure Web (SSL) Platform for Application Acceleration Multiprotocol Accelerated Caching Hierarchy

  15. Bandwidth Management Sales Automation AppPriority 1 Min 400Kb, Max 800Kb E-Mail Priority 2 Min 100Kb, Max 400Kb • Divide user and application traffic into classes • Guarantee min and/or max bandwidth for a class • Align traffic classes to business priorities File Services Priority 3 Min 400Kb, Max 800Kb General Web Surfing Priority 4 Min 0Kb, Max 200Kb

  16. Protocol Optimization

  17. 10-100X Faster Includes CIFS, MAPI, HTTP, HTTPS, TCP Protocol Optimization

  18. Object Caching • Built on high-level applications and protocols • HTTP/Web caching • Streaming caches • CIFS cache • Advantages • Fastest response times • Offload work from servers (and networks) • Can be deployed asymmetrically • Limitations • Application-specific • All or nothing: No benefit if whole object not found or changed
