  2. Agenda • General Benefits of Content Caching • What is CacheXpress? • Features of CacheXpress • Implications for Broadband Networks • CacheXpress How Tos on • Deploying, • Configuring and • Monitoring • Summary

  3. Benefits of Using Content Caching • Smaller bandwidth • Faster Response • 30-40% Avg Hit Rates • 25% Avg Bandwidth Savings • ROI is approx 3-4 months

  4. A Caching Proxy Server that is better than Squid, using patented WhirlWind Engine • PC Magazine Award winnerCache Server roundup 1999 – best performing Squid-base Cache (known as Industrial Code & Logic then) • First in transparent web proxy-caching modelFor the Microsoft Windows NT operating system platform. • First to offer WCCP (v1 & 2) support for WinNT/2000

  5. CacheXpress Features • Easy Web-Based Management • Higher Performance (120 vs 500) • Eliminates Bandwidth Hogs • Optimizes Multiple Links Usage with ICP • Access Control Solutions based on: • Source/Destination • Radius or Internal User • HTTP Header • Scalable Transparent Cacheing

  6. Benefits to Broadband Networks • Limited Int’l bandwidth, • Unlimited Local Bandwidth • Proxy Peer among all broadband users • DSL Pilot Experience

  7. Deploying CacheXpress • Best with Windows 2k or XP • Download & Install • Configure Initial Port Settings Supervisor Acct • Determine Cache Size • CacheSize= (PeakLoad * 432) • PeakLoad= (#Dialups * .02) or (#LANUsers * .002) • ROT: 1gb + 50mb / user • Setting Cache Size

  8. Applying Access Security 192.168.0.2 202.91.161.141 192.168.0.3 192.168.0.1 Demo

  9. Limiting Access via Http Header Info • Limiting Access to QuickTime • Limiting Access to Large Objects • Requesting that Large Objects not be Cached

  10. Accessing Upstream Caches ISP1 ISP2 Allows you to Maximize Multiple Internet Provider Links! This is You!

  11. Setting bandwidth limits per unit/person/ip class • Define Bandwidth Settings • Apply Control Rules • Scenario: • 512kb internet link • Limit to 80% of bandwidth • No limit if they are browsing Bitstop Website

  12. Using Radius or Internal User list for Authentication • Scenario1 : Allow Access to Internal User but deny access to a Group • Scenario2 : Allow Radius-Based Access

  13. Setting up Scalable Tranparent Caching

  14. Monitoring Cache Operations • Overview • Logs • Cache • Peers • WCCP
