Abstract
Method, systems, and computer program products for identifying the application-level protocol of a signaling message are disclosed. According to one method, a message copied by a network monitoring system is received. The service indicator in the message is examined to determine whether more than one application-level protocol is possible. If more than one application-level protocol is not possible, the application-level protocol is identified based on the service indicator. If more than one application-level protocol is possible, additional message attributes are individually examined to determine whether identification of the application-level protocol is possible based on each attribute. The application-level protocol is identified based on the first attribute for which identification is determined to be possible.
