The Bandwidth module is a licensed feature of your Smoothwall. It's separate from the bandwidth limiting function found within the proxy settings. If you're licensed, you can install the Bandwidth module through your Smoothwall’s user interface. To take advantage of the full functionality of the Bandwidth module, you need a Layer 7 license.
With the Bandwidth module you can shape the traffic throughput of specified external or bridged interfaces and create multitiered, application-aware, bandwidth shaping policies. However, there are limitations. For example, you can only shape traffic that uses external or bridged ports.
The Bandwidth module doesn't block applications from accessing the Internet. Traffic that's redirected through the Guardian module isn't classified as originating from the client but from your Smoothwall instead. Traffic shaping configured in the Guardian module might overlap with configuration in the Bandwidth module. In such cases, both configuration rules are applied. However, the smallest limit always overrides the latter. For example, if you have a policy to limit “news” traffic to two megabits per second within the Guardian module, but within the Bandwidth module you limit all HTTP traffic to only one megabit per second, only the Bandwidth module's limit is applied.
The following are example scenarios where you can use the Bandwidth module to tailor your bandwidth.
Network services can be tailored for each type of guest service at the hotel:
Business critical applications can be given priority over other applications. This can be further customized for each department, for example:
Bring your own device (BYOD) services can be limited to a specific bandwidth share per user, with access to some applications restricted to the point where they're virtually unusable.
