Abstract
In an embodiment, a communication node coupled to a first data network and a second data network is disclosed. The first data network is a wide area data network. The communication node includes a first data interface to the first data network, a second data interface to the second data network, a data processor responsive to the first data interface and to the second data interface, and an encryption module coupled to the data processor. The first data interface is a telephony type interface and the second data interface is a packet data interface. The data processor receives input traffic data carried over the first data interface and generates management performance data based on measurements with respect to the input traffic data. The encryption module receives the management performance data to produce encrypted management performance data to be communicated to the second data network via the second data interface.
