Abstract: In a packet switched network, network data can be recorded for measurement by transmitting a measurement packet across the network to store path records as it travels from an originating measurement device to a destination device. Some of the network devices located along the path traversed by the measurement packet are capable of recognizing that the measurement packet no longer has any further storage capacity for path records. The network device then copies or clones the measurement packet and erases the path record data from the original measurement packet. The original measurement packet then continues on its path to the destination address collecting further path records on the way, while the cloned packet is returned to the measurement host for processing of the path records when all cloned packets and the original measurement packet return to the measurement host.

Abstract: The problems inherent with connecting a DUT to a test station have been solved by the use of a tray designed to allow a wide variety of different DUTs to be physically connected individually to a test station using a universal test station connector. The tray allows for the association therewith of a personality module which serves to provide the proper physical connections and to electrically condition the test station to the electrical characteristics of the DUT. The tray allows for sealed environmental testing of the DUT without impacting any physical connections between the DUT and the test station. The tray also allows for the DUT to be vibrated from externally applied motion without interfering with either the sealed environment around the DUT and without imparting motion to the physical connection between the DUT and the test station.

Abstract: In the field of monitoring communications systems, it is necessary for a monitoring system to be aware of an association of a Mobile Country Code (MCC), a Mobile Network Code (MNC) and an IP Address of a Gateway GPRS Support Node (GGSN) of a first network when a mobile terminal is roaming into a second network. Probes monitoring links with the second network generate transaction data. The transaction data is generated from messages communicated as part of a dialogue to establish a data “tunnel” between a Serving GPRS Support Node (SGSN) of the second network and the GGSN of the first network. The MCC, MNC and IP address data are extracted from the transaction data and used to update an address network name table.
