Bandwidth throttling Web filtering Supporting functions 6 You can limit the speed for uploading and downloading data to the appliance in a process also known as bandwidth throttling. This section explains how this process is configured and provides two examples of bandwidth throttling rules. You can use bandwidth throttling, for example, to avoid a situation where the network performance you need for completing a particular task is impacted by other users who are individually uploading objects to the web or are requesting large downloads from the web. Bandwidth throttling events Two events are available for use in rules that can trigger bandwidth throttling: • The Throttle.Client event limits the speed of data transfer from a client to the appliance. This is the case when a client sends a request for uploading an object to a web server and the request is intercepted on the appliance together with the object. • The Throttle.Server event limits the speed of data transfer from a web server to the appliance. In this case, there has been a client request to download an object from a web server, and after this request has been filtered on the appliance and forwarded, the web server sends the object in response. The transfer speed is measured in Kbps (kilobits per second). The events both have a parameter for specifying the maximum speed that should be used during a transfer. The lowest value that you can specify here is 10 Kbps. Bandwith throttling rule for uploads The following is an example of a rule that can execute bandwidth throttling rule for uploads. Note: The example shows approximately how the rule appears on the user interface. Name Limit upload speed for hosts on throttling list Criteria Action Event URL.Host is in list Upload Throttling List –> Continue – Throttle.Client (10) The rule uses the Throttle.Client event to limit the speed with which uploads are performed to 10 Kbps if the web server that the data should be uploaded to is on a particular list. In the criteria of the rule, the URL.Host property is used to retrieve the host name of the web server that is specified in the uploading request. If the Upload Throttling List contains this name, the criteria is matched and the rule applies. The throttling event is then executed. The Continue action lets rule processing continue with the next rule. McAfee Web Gateway 7.1.5 Product Guide 231
