    • The preferred embodiments include a method, system or computer-readable storage medium for identifying analog access line impairments in a communications network. The embodiments include determining a ping packet loss count and a ping failure count from digital packet loss data associated with at least one analog access line. The embodiments also include generating a line designation for the at least one analog access line in response to the ping packet loss count exceeding a first threshold and the ping failure count exceeding a second threshold. Also, a plurality of pings can be transmitted during a testing period, the digital packet loss data being generated in response to the plurality of pings. The first threshold can represent at least a three percent ping packet loss. The second threshold can represent the ping failure count being at least ten percent of a total number of the plurality of pings.
    • 优选实施例包括用于识别通信网络中的模拟接入线路损伤的方法,系统或计算机可读存储介质。 实施例包括从与至少一个模拟接入线相关联的数字分组丢失数据确定ping分组丢失计数和ping失败计数。 这些实施例还包括响应于超过第一阈值的ping分组丢失计数和超过第二阈值的ping失败计数来生成用于至少一个模拟接入线路的线路指定。 此外,在测试期间可以发送多个ping,数字分组丢失数据是响应于多个ping而产生的。 第一个阈值可以表示至少三分之一的ping数据包丢失。 第二阈值可以表示ping失败计数是多个ping的总数的至少百分之十。

    • A method and apparatus for establishing traffic priorities in an IP network connected with multiple communication sources is disclosed. Different types of packets such as voice packets and data packets are received for transmission over a single network access link. In order to assure quality voice transmissions, voice packets are given priority over data packets by limiting a transmission rate from a data input queue whenever voice packets are detected in a voice input queue. Different combinations of interleaved voice and data packets help to alleviate packet congestion while maintaining priority for voice packets. In one aspect of the invention, priority for voice packets is further accomplished by limiting the size of data packet frames. In some instances when no voice packets are awaiting transmission, data packets are transmitted at a maximum rate in order to make full use of the network access link bandwidth. The invention is particularly beneficial when implemented over cable and DSL network access links with slow upstream feed rates.
    • 公开了一种用于在与多个通信源连接的IP网络中建立业务优先级的方法和装置。 接收不同类型的分组,例如语音分组和数据分组,以通过单个网络接入链路进行传输。 为了保证高质量的语音传输,每当语音输入队列中检测到语音分组时,通过限制来自数据输入队列的传输速率,语音分组被优先于数据分组。 交织语音和数据分组的不同组合有助于缓解分组拥塞,同时保持语音分组的优先级。 在本发明的一个方面,语音分组的优先级进一步通过限制数据分组帧的大小来完成。 在没有语音分组正在等待传输的情况下,以最大速率发送数据分组,以充分利用网络接入链路带宽。 当通过具有缓慢的上游馈送速率的电缆和DSL网络接入链路来实现时,本发明是特别有益的。
