Cell Transfer Time Measurement Using the Parallel Cell / Traffic Generator and Analyzer How to use the HP E4829B custom / UTOPIA Level 1 implementation for cell transfer time variation measurements Product Note Product Number HP E4829B bandwidth which is normally Application wasted when other techniques, such as TDM, are used (see [2]). Network equipment manufacturers To measure cell transfer time variation in a communication For hardware and software system interacting with ATM cells, engineers in the communications the HP E4829B test system is able industry, designing ICs and to log and extract time-stamp modules for ATM switches, or information flowing into and from working in system integration, the the payload of ATM cells. This HP E4829B parallel cell / traffic Figure 1: HP E4829B entry system measurement can be made at generator and analyzer system, Introduction parallel to parallel (UTOPIA) which can measure cell transfer ports, either at the switch fabric time variation, is the basic tool for In order to achieve quality of ports or at the ATM layer device the evaluation of complex service in an ATM switch, any interfaces, as shown in figure 2. ATM designs at parallel interfaces variations in the cell transfer time (UTOPIA). of channels carrying voice data must be closely monitored. When the delay variation exceeds certain limits, the quality of voice sent to the user is reduced. The designer's Switch, hubs, routers goal, therefore, is to ensure that any variation in the transfer time CPU of the traffic at the switch fabric is
