Ensuring a quality subscriber experience is a critical requirement in traditional and mobile carrier networks. Monitoring subscriber experience in these traditional carrier and mobile networks is well understood. It involves tapping into the necessary network links with a network tap or using a mirroring port on the network switches.
The mirrored traffic is then groomed and/or correlated by a network packet broker before being fed to an appropriate set of customer experience assurance tools or probes. The CEA tools are a key element in the carrier operations support system/business support system infrastructure.
