Abstract
Service detail records (SDRs) are generated for at least two layers in a stack of protocols used in a communications network, where protocol data units (PDUs) for a lower-level protocol encapsulate PDUs for a higher-level protocol. SDRs for the higher-level protocol include pointers to SDRs for connections at the lower level which encapsulate PDUs from which the higher-level SDRs were generated.
