Best Practice for PacketShapers in IntelligenceCenter who desire to use the URL Detection and Categorization Feature
This best practice guide applies to IntelligenceCenter installations running IC 2.1.x or 3.x.x versions which provide visibility reporting services to Packet shapers running PacketWise 8.6.0 or later. Prior to this point in time, PacketShapers did not have the feature known as URL Auto Discovery.
Description of Effects of Feature
This feature will automatically provide a URL breakdown of website traffic, similar to the way that auto discovery of classes works for applications. Furthermore it applies categorization of the URLs discovered using the Blue Coat WebFilter service. This provides increased visibility into network HTTP traffic usage. The URLs discovered count as a class like any other from the Packet Shaper’s perspective and the PacketShaper will continue to collect URLs until such time as its class count maximum is reached. When URL categorization is turned on and the WebPulse Query option is enabled, PacketShaper will send URL queries to the WebPulse cloud service; the service will look up the URL in its extensive database to find the category (or categories) associated with the URL, and send the response back to the PacketShaper for classification.
Web URLs can be grouped into various categories, such as social networking, gambling, pornography, news media, and shopping. PacketShaper is able to analyze the URLs that users are requesting, determine what category the website belongs to, and classify the traffic into the appropriate category class. This gives you granular visibility into the type of web traffic on your network. You can also use Packet Shaper’s control capabilities to assign policies based on the category. For example, you can assign a never‐admit policy to all the category classes with adult content. This feature was introduced in Packet Wise version 8.6.0.
