- The Application Classifier
- Service Classes
The application classifier uses application definitions to categorize the traffic by protocol and application. This information is used to create reports, and by the service-class mechanism. Many applications are already defined, and you can define more as needed.
The application classifier uses the official protocol and port specifications from the Internet Assigned Numbers Authority (IANA), http://www.iana.org . Sometimes applications other than the official ones use a port. The classifier generally cannot detect such use. If your network uses such applications, you can usually resolve this problem by renaming the application, in the application classifier, to indicate the actual application that uses this port on your network. For example, if you use port 3128 not for its standard use for a Squid web cache, but for a SOCKS proxy, you could rename the Squid (TCP) application to S OCKS (Port 3128) for clarity.
Applications must not have overlapping definitions. For example, if one application on your network uses TCP ports 3120 and 3128, and another application uses port 3120, only one CloudBridge application definition can include port 3120.
