    • PURPOSE: An estimation method of performance of data service without allowing delay is provided to offer streaming data service, and to evaluate switching performance of data switching nodes by evaluating data transfer waiting time, data carriage jitter, and data division loss. CONSTITUTION: An estimation method evaluates the performance of a data exchange facility at the time of processing and carrying the stream of data affecting delay, jitters, and losing. An evaluating device contains a record(120) tracking reception and a record(160) tracking transmission, and the estimation method also evaluates the performance of the data exchange facility by investigating the reception record and the transmission record. The advantage includes the function of enabling the offer of streaming data service by evaluating data transfer waiting time, data carriage jitter, and data division loss. The performance of data switching nodes(100) is evaluated by deciding data transfer delay, data carriage jitter and data loss in processing Protocol data units according to the reception record and the transmission record.
    • 目的:提供不允许延迟的数据业务性能的估计方法,以提供流数据服务,并通过评估数据传输等待时间,数据传输抖动和数据分区丢失来评估数据交换节点的切换性能。 构成:估计方法评估数据交换设施在处理和承载影响延迟,不稳定和丢失的数据流时的性能。 评估装置包括记录(120)跟踪接收和记录(160)跟踪传输,并且估计方法还通过调查接收记录和传输记录来评估数据交换设施的性能。 优点包括通过评估数据传输等待时间,数据传输抖动和数据分割丢失来实现流数据服务的提供功能。 数据交换节点(100)的性能通过根据接收记录和传输记录决定处理协议数据单元中的数据传输延迟,数据传输抖动和数据丢失来进行评估。

    • PURPOSE: A traffic controlling method for individual user and an apparatus thereof are provided to implement the traffic control per user considering an user usage property in a generation of a strange traffic sign. CONSTITUTION: A statistical processor(130) measure a traffic amount used by a per user. The statistical processor calculates a traffic variation using the measured traffic amount. The statistical processor updates a traffic user list comparing with the calculated traffic variation. A traffic detector(140) transmits a control command according to a order of priority of the traffic user list. A packet controller(150) controls the traffic of the user according to the received control command from the traffic detector.

    • PURPOSE: An apparatus is provided to reduce communication expenses extremely and to expand a bandwidth by compressing and multiplexing voice/data between switching systems with the use of a frame relay protocol. CONSTITUTION: A PCM connection part(120) is connected to a PCM highway of a switching system back plane. A leased-line connection part(150) is connected to data leased-lines. Compressed and multiplexed PCM data from the PCM connection part(120) is transmitted from the leased-line connection part(150). A compressing/multiplexing part(130) decompresses and demultiplexes the PCM data compressed and multiplexed from the leased-line connection part(150) and then transmits the decompressed and demultiplexed PCM data to the PCM connection part(120). A control part(110) controls a frame relay protocol application.
