23. ApplianSys: customer testimonials “There’s a significant improvement in the reliability and quality of our service. We’re also advertising our caching capability to potential customers. It’s helping us stand out in the market place and win more business. I chose CACHEBOX from ApplianSys because the company has a strong focus on web caching solutions...Quite simply, the CACHEBOX is the ideal solution for ISPs operating where internet bandwidth is in short supply or very expensive.” Teledata ICT, Ghana “Our customer is extremely satisfied with the performance enhancement. They pay us $3,075 monthly for bandwidth and will remain on this bandwidth for a very long time to come because there will be no need to upgrade, courtesy of CACHEBOX. They will be saving in the region of $24,000 per annum. They are so happy they have now recommended us to another two of their branches; that is why we just ordered five more boxes.” Swifttalk, Nigeria “The CACHEBOX has been online for two weeks but, even in that short space of time, the difference has been dramatic. It was an ‘Oh my god’ moment from the first day. ApplianSys was the best provider for a small ISP like ourselves – they offered usability, a tailored solution and an open-source based system. The extra bandwidth helps keep us connected with the rest of the world.” Esplanade Wireless, USA "With the ApplianSys solution we make significant savings on our internet access, it's almost a third of what we were paying previously. For a region our size that's a saving of £35,000 per year...but the main benefit is the improvement in delivery; workstation performance in the classroom is now spectacular. It all leads to a much better perception of the quality of service we're delivering to our customers." Leeds Learning Network, UK “Since installing CACHEBOX we’ve seen tremendous benefits...We regularly get hit rates of 40% and with large object caching picking up the web videos, we’ve been adding a lot more subscribers to our network.” Karib Cable Kelcom, St Vincent YOUR ISSUES– CACHEBOX – APPLIANSYS – NEXT STEPS

26. Different ways to deploy Caching video Caching software updates Choosing the right model Would you like more detail? ISP deployment End presentation

27. Explicit WCCP / Routing Transparent Gateway mode CACHEbox can be deployed in different ways • Accelerating general web traffic for users accessing the Internet • Browsers are configured to make requests via CACHEBOX FORWARD or • Network or routing is modified so that traffic flows via CACHEBOX • Users unaware of cache or or REVERSE • Accelerating requests from Internet / network to one or more web servers MORE DETAIL: DEPLOYMENT METHODS

28. Explicit WCCP / Routing Transparent Gateway mode Let’s look at these options in more detail…. FORWARD or or or REVERSE MORE DETAIL: DEPLOYMENT METHODS

29. Forward Transparent - with WCCP / routing • Existing router or switch redirects HTTP traffic to CACHEBOX • Client browsers do not need configuring • Best option for ISP use • CACHEBOX can make requests using the client’s IP • Multiple CACHEBOXes can be clustered together MORE DETAIL: DEPLOYMENT METHODS

30. Explicit WCCP / Routing Transparent Gateway mode Let’s look at these options in more detail…. FORWARD or or or REVERSE MORE DETAIL: DEPLOYMENT METHODS

31. Forward Transparent - gateway mode • Clients or network devices use CACHEBOX as their default gateway • CACHEBOX caches HTTP traffic, passing rest through • Recommended only in small networks, as it introduces a single point of failure MORE DETAIL: DEPLOYMENT METHODS

32. Explicit WCCP / Routing Transparent Gateway mode Let’s look at these options in more detail…. FORWARD or or or REVERSE MORE DETAIL: DEPLOYMENT METHODS

33. Forward explicit deployment • Browsers are configured to send HTTP traffic via CACHEBOX, by • Changing settings in Internet Options on each PC • Using PAC files to let browsers detect settings • Using Active Directory to push settings to each Windows PC • Not suitable for ISP environments MORE DETAIL: DEPLOYMENT METHODS

34. Explicit WCCP / Routing Transparent Gateway mode Let’s look at these options in more detail…. FORWARD or or or REVERSE MORE DETAIL: DEPLOYMENT METHODS

35. Reverse caches: deployed in front of web servers • Commonly used to: • Offload static content from dynamic sites • Accelerate content from web servers on slow Internet links (such as those hosted at company HQ), placing CACHEBOX in a datacenter • Move content closer to users, creating a CDN MORE DETAIL: DEPLOYMENT METHODS

36. PROBLEM They serve the same files from multiple servers with different URLs So files from each URL get cached, filling up storage and not saving bandwidth The “rules” for determining the URLs of different servers are often changed by content providers SOLUTION CACHEBOX identifies video files and caches a single copy from the first URL it is requested from It then serves the cached file, whatever URL is next requested ApplianSys monitors content provider URLs and updates CACHEBOX software automatically when the rules change Most video-sharing sites use Flash or MPEG files served over HTTP which normally can not be cached MORE DETAIL: CACHING VIDEO

37. Operating Systems, Antivirus and software packages use HTTP to download updates PROBLEM • These update downloads can not normally be cached • Traditional caches are only effective if a whole file is requested • If part of a file (a “range request”) is requested it will be served but not cached SOLUTION • CACHEBOX is smarter. When a range request is served, the entire file is downloaded in parallel • Future requests can be served from cache MORE DETAIL: CACHING SOFTWARE UPDATES

38. Choosing The Right Model • CACHEBOX has no licence limits based on number of users • The only limit on each model is the number of HTTP requests per second (RPS) the hardware can support • Performance is not measured in throughput: 1 user on a 10MBit ADSL line will generate less traffic than 1000 users on a 5MBit satellite connection • Published RPS figures are measured in a test environment using benchmark software. Real life performance will vary dependent on • Type of traffic & network setup • Other factors, such as Denial of Service attacks MORE DETAIL: CHOOSING THE RIGHT MODEL OF CACHEBOX

39. Choosing The Right Model • CACHEBOX050/100 are entry-level devices for lower loads • CACHEBOX230 is ideal for top performance with large object storage optimised for video content • CACHEBOX220is ideal top performance where there is less video content or software update downloading • CACHEBOX210offers good value at mid-performance levels MORE DETAIL: CHOOSING THE RIGHT MODEL OF CACHEBOX

40. CACHEBOX is popular with ISPs: the benefits of performance caching at sensible prices are obvious • Save money • More customers on a fixed bandwidth, or • Save metered bandwidth • Easy to deploy appliance MORE DETAIL: INTERNET SERVICE PROVIDER DEPLOYMENT

41. The right models deliver performance caching at sensible prices for ISPs of different sizes • CACHEBOX230and CACHEBOX220- first cache appliances to use Solid State Drives (SSD), for speed and reliability • Can be clustered to handle a very heavy caching workload • Depending on type of traffic, supports >10,000 users per appliance • Other vendors only offer this performance with bigger, expensive devices • CACHEBOX230also stores up to 1 Terabyte (TB) of larger files - like internet video - from Google, YouTube and similar sites • CACHEBOX210is perfect for small ISPs, with excellent performance at a low price point MORE DETAIL: INTERNET SERVICE PROVIDER DEPLOYMENT

42. The right models deliver performance caching at sensible prices for ISPs of different sizes • CACHEBOX100is a 1U rack-mount appliance suited to very small ISPs • CACHEBOX050has the same features and performance as the ‘100’ but in a mini-appliance device • You can use it alone or with ‘200’series models deployed further upstream. • Some ISPs sell low-end models to business customers so that they can get more from their bandwidth MORE DETAIL: INTERNET SERVICE PROVIDER DEPLOYMENT
