MEASUREMENT SYSTEM FOR PERFORMANCE OF CELL TRANSFERRING SYSTEM IN ATM SWITCH

摘要

The present invention is a cell delivery system of an ATM switching system operating as a node in a broadband communication network.;The present invention relates to a measurement device for measuring performance, and provides a measurement device for measuring cell delivery system performance of an ATM switching system by measuring and storing arrival time intervals of an actual ATM service cell in advance and using the data as cell generation interval setting data. In order to do so, using a commercially available SDH chip, UNI matching means 23 for matching with the external ATM switching system 12;;ATM cell generation and means (22) for generating an ATM cell and verifying cell information looped back through the ATM switching system via the system bus (24) and UNI matching means; Storage means (13) for storing the ATM cell generation time interval data for each service; And reading the cell generation time interval data from the ATM cell generation and verification means 22 via the system bus 24 and storing it in the storage means 13, and splitting the cell generation time interval data into a cell discard rate. And a central processing unit (CPU) and a memory 21 for outputting an error rate to an operator, thereby accurately measuring cell performance.
