New, Internet-Based Applications Bring Change and Challenge to Lawful Interception

Customarily seen as disparate areas, network performance management and lawful interception (LI) have recently begun to converge. In concept this should be no surprise, as the two disciplines share a common foundation: LI involves examining network traffic to identify and collect specific content, while network performance management examines network traffic to identify specific performance parameters. However, despite a common approach, this convergence is relatively recent, as both disciplines have begun to draw upon one another for mutual benefit.
