METHOD OF CONTROLLING FLOW OF PTN SERVICES

摘要

FIELD: radio engineering, communication.;SUBSTANCE: invention relates to a method of controlling flow of packet transmission network (PTN) services. The method comprises the following steps: step 1 - in a network management server, corresponding ports of a defined service are set in sampling mode and the sampling interval and the sampling start-stop time are set; step 2 - the server samples stream data of ports set in sampling mode in real time based on the sampling interval during the sampling start-stop time; step 3 - a network element device sends stream data in real time back to the server for storage; step 4 - a network management client receives from the server the name of the network element device, the names of ports set in sampling mode of initial ports and target ports of the service whose stream data being transmitted from the server in real time are pre-sampled; step 5 - the network management client displays on a screen interface an end-to-end service whose stream data are sampled in the PTN in real time.;EFFECT: change in real-time flow of ports of a PTN device can be controlled in real time, change in real time can be controlled constantly and real-time change in flow from maximum to minimum can be observed.;5 cl, 4 dwg
