  • History Lesson

    • Controlling Chaos

      • iPod dominates digital players (90% of the market)

      • Apple posted the best quarter in their history ($9.6 billion) with 42% coming from iPod sales

      • Industries like health, education, and law now use iPods (podcasting) to post information, news, etc.

  • Controlling Chaos

    • When there is high demand

      • There will be short supply

      • There will be a need to control that demand

    • More supply can never eliminate demand

    • Control can balance both supply and demand and increase performance

  • Controlling Content

    • URL database is a structured collection of URLs and their corresponding categories.

    • URL database filtering most common method used for controlling content

  • Controlling Content

    • URL Database

      • Advantages

        • Accuracy on “constant” web sites

        • Fast categorization on “constant” web sites

      • Disadvantages

        • Size of database versus size of Internet

        • Web pages with different content

        • Update time for new web sites


Internet trends 2 016 l.jpg
Internet Trends 2.0

  • Controlling Content

    • URL Database

      • Internet—165,719,150 web sites

        • 29.7 billion total web pages

        • 3 to 4 million new web sites each month

      • URL Database—35 million web sites

        • 21% of all web sites

  • Controlling Content

    • URL Database

      • Dynamic web pages within web sites

        • Most of this year’s growth of new web sites is due to Google’s Blogger service, adding 1.1 million extra sites.

        • Web sites such as blogs, search engines, online communities may have different content on individual pages.

  • Controlling Web Page Delivery

    • What method to chose?

      • Use a combination of methods that will offset weaknesses and combine strengths

      • Other methods to include are signature-based detection, code analysis, URL reputation, and traffic behavior.

      • 360° view of your network and not just a piece of the puzzle

Internet Trends 2.0

  • Controlling Resources

    • From 2000 to 2005 the total volume of streaming media grew by 600%

    • The average Web page grew by 233% and the number of objects doubled 21 times

    • YouTube takes up 10% of all bandwidth for entire Internet

  • Controlling Resources

    • Comcast begin testing “protocol-agnostic” network management systems in two markets.

    • Time Warner Cable will charge users a $1 per Gigabyte fee for bandwidth they use beyond a preset threshold.

  • Controlling Resources

    • Controlling Bandwidth

      • Application Acceleration

      • Bandwidth Shaping

      • Quality of Service


Internet trends 2 025 l.jpg
Internet Trends 2.0

  • Controlling Bandwidth

    • Application Acceleration is usually a combination of technologies that increases traffic speed, usually through WAN connections.

      • Data compression

      • Caching

      • Advantage is that for supported applications, latency can be reduce and accelerated

      • Disadvantage is that doesn’t work well with voice traffic and not all applications can be accelerated


Internet trends 2 026 l.jpg
Internet Trends 2.0

  • Controlling Bandwidth

    • Bandwidth Shaping, also known as bandwidth limiting or traffic shaping, is a technology that allows you to limit the amount of bandwidth consumed by a user or by an application.

      • Advantage is that all traffic can be controlled, either by a user level or by an application level

      • Disadvantage is that it does not accelerate traffic


Internet trends 2 027 l.jpg
Internet Trends 2.0

  • Controlling Bandwidth

    • Quality of Service (QoS)—is similar to bandwidth shaping in that it can regulate network bandwidth but QoS can also reserve bandwidth to guarantee that it will be available when needed.

      • Advantage is that you can guarantee a threshold for a specific device or protocol

      • Disadvantage is reserved bandwidth cannot be used regardless of current load


Internet trends 2 028 l.jpg
Internet Trends 2.0

  • Controlling Resources

    • Controlling Bandwidth

      • Which technology is right for your network?

      • Do you need to speed up traffic?

      • Do you need to slow down traffic?

      • Can the solution control total traffic, application traffic, and web site traffic?
