对于数据拥塞、带宽不足、业务质量下降等故障，目前较多采用人工故障排查方式，且一般为用户保修后才进行人工故障排查，无法实现常态化监控，从而由于工单处理、人工排查等耗时耗力的环节较多，使得网络的运营效率降低。

参照图2，本公开实施例提供的一种网络质量评价方法，包括如下步骤200至步骤201。
步骤200、获取网络传输特征参数。
在一些实施例中，网络传输特征参数包括以下至少之一：网络侧的第一传输特征参数和用户侧的第一传输特征参数；第二传输特征参数；及第三传输特征参数。
在一些实施例中，获取网络传输特征参数包括以下至少之一：分别获取网络侧的第一传输特征参数和用户侧的第一传输特征参数；获取第二传输特征参数；获取第三传输特征参数。
在一些实施例中，网络侧的第一传输特征参数是指网络侧的数据包的传输特征参数，也就是能够体现网络侧的数据包的传输过程的特征参数。
在一些实施例中，网络侧的数据包可以是接收的网络侧发送的数据包，也可以是发送给网络侧的数据包，也可以是接收的网络侧发送的数据包和发送给网络侧的数据包。
在一些实施例中，用户侧的第一传输特征参数是指用户侧的数据包的传输特征参数，也就是能够体现用户侧的数据包的传输过程的特征参数。
在一些实施例中，用户侧的数据包可以是接收的用户侧发送的数据包，也可以是发送给用户侧的数据包，也可以是接收的用户侧发送的数据包和发送给用户侧的数据包。
在一些实施例中，网络侧的第一传输特征参数或用户侧的第一传输特征参数包括以下至少之一：目标业务的最小相对抖动值、目标业务的最大相对抖动值、目标业务的平均相对抖动值、目标业务的上行网络速率值、目标业务的下行网络速率值、目标业务的上行目标类型的数据速率值、目标业务的下行目标类型的数据速率值，其中，目标类型为用户侧和网络侧通信所使用的通信协议类型。
在一些实施例中，目标业务可以是任何需要进行网络质量评价的业务，例如，网际协议电视(IPTV，Internet Protocol Television)业务、经由网际协议的语音通话(VOIP，Voice over Internet Protocol)业务等。
在一些实施例中，目标类型例如可以是传输控制协议(TCP，Transport Control Protocol)类型，也可以是用户数据报协议(UDP，User Datagram Protocol)类型，当然，也可以是其他通信协议类型，本公开实施例对此不作限定。
当然，第一传输特征参数还可以是其他参数，本公开实施例对具体的参数形式不作限定。
下面分别介绍上述每一个第一传输特征参数的获取方式。
(一)目标业务的最小相对抖动值
在一些实施例中，第一传输特征参数包括目标业务的最小相对抖动值。分别获取网络侧的第一传输特征参数和用户侧的第一传输特征参数包括：分别获取网络侧的目标业务的n对数据包的相对抖动值和用户侧的目标业务的n对数据包的相对抖动值，其中，n为大于或等于1的整数；根据网络侧的目标业务的n对数据包的相对抖动值计算网络侧的目标业务的最小相对抖动值；根据用户侧的目标业务的n对数据包的相对抖动值计算用户侧的目标业务的最小相对抖动值。
在一些实施例中，网络侧的目标业务的每一对数据包可以是指接收到的网络侧发送的目标业务的相邻两个数据包。例如，网络侧的目标业务的第i对数据包包括：接收到的网络侧发送的目标业务的第i个数据包(下述的另一个数据包)和网络侧发送的目标业务的第(i+1)个数据包(下述的其中一个数据包)。
在一些实施例中，用户侧的目标业务的每一对数据包可以是指发送给用户侧的目标业务的相邻两个数据包。例如，用户侧的目标业务的第i对数据包包括：发送给用户侧的目标业务的第i个数据包(下述的另一个数据包)和发送给用户侧的第(i+1)个数据包(下述的其中一个数据包)。
当然，网络侧的目标业务的每一对数据包也可以是接收到的网络侧发送的目标业务的非相邻的两个数据包，用户侧的目标业务的每一对数据包也可以是向用户侧发送的目标业务的非相邻的两个数据包。但是，需要说明的是，对于目标业务的同一对数据包，应该分别计算网络侧对应的相对抖动值和用户侧对应的相对抖动值。也就是说，虽然每一对数据包可以是任意两个数据包的随意组合，但是组合一旦确定，应该分别计算该对数据包对应的网络侧对应的相对抖动值和用户侧对应的相对抖动值，以实现网络侧和用户侧的相对抖动值的比较。
在一些实施例中，定义网络侧发送的目标业务的第i个数据包为P w，i，网络侧发送目标业务的第i个数据包的时间为T w，i，当前设备(执行主体，如OLT)接收到网络侧发送 的目标业务的第i个数据包的时间为T’ w，i，网络侧发送的目标业务的第(i+1)个数据包为P w，i+1，网络侧发送目标业务的第(i+1)个数据包的时间为T w，i+1，当前设备(执行主体，如OLT)接收到网络侧发送的目标业务的第(i+1)个数据包的时间为T’ w，i+1。
根据延迟时间的定义，目标业务的第i个数据包P w，i的延迟时间为L w，i＝T‘ w，i-T w，i；目标业务的第(i+1)个数据包P w，i+1的延迟时间为L w，i+1＝T‘ w，i+1-T w，i+1；
根据抖动值的定义，网络侧的目标业务的第i个数据包P w，i和网络侧的目标业务的第(i+1)个数据包P w，i+1的抖动值为：
J w，i＝L w，i+1-L w，i＝T’ w，i+1-T’ w，i-(T w，i+1-T w，i)；
其中，J w，i为网络侧的目标业务的第i个数据包P w，i和目标业务的第(i+1)个数据包P w，i+1的抖动值，T w，i+1为网络侧发送目标业务的第(i+1)个数据包的时间，T w，i为网络侧发送目标业务的第i个数据包的时间，T’ w，i+1为接收到网络侧发送的目标业务的第(i+1)个数据包的时间，T’ w，i为接收到网络侧发送的目标业务的第i个数据包的时间。
由于抓包工具在当前设备接收到数据包时便抓取数据包，抓包工具抓取数据包的时间和当前设备接收到数据包的时间之间的差别可以忽略不计。因此，T’ w，i+1可以通过抓包工具抓取接收到的目标业务的第(i+1)个数据包的时间来确定，T’ w，i可以通过抓包工具抓取接收到的目标业务的第i个数据包的时间来确定。
而T w，i+1和T w，i无法获知，因此，可以定义网络侧的目标业务的第i对数据包的相对抖动值为J w，i+T w，i+1-T w，i。
同样，根据抖动值的定义，用户侧的目标业务的第i个数据包P u，i和用户侧的目标业务的第(i+1)个数据包P u，i+1的抖动值为：
J u，i＝L u，n+1-L u，n＝T’ u，i+1-T’ u，i-(T u，i+1-T u，i) ；
其中，J u，i为用户侧的目标业务的第i个数据包P u，i和目标业务的第(i+1)个数据包P u，i+1的抖动值，T u，i+1为向用户侧发送目标业务的第(i+1)个数据包的时间，T u，i为向用户侧发送第i个数据包的时间，T’ u，i+1为用户侧接收到目标业务的第(i+1)个数据包的时间，T’ u，i为用户侧接收到目标业务的第i个数据包的时间。
由于抓包工具在当前设备发送数据包时便抓取数据包，抓包工具抓取数据包的时间和当前设备发送数据包的时间之间的差别可以忽略不计。因此，T u，i+1可以通过抓包工具抓取发送目标业务的第(i+1)个数据包的时间来确定，T u，i可以通过抓包工具抓取发送目标业务的第i个数据包的时间来确定。
而T’ u，i+1和T’ u，i无法获知，因此，可以定义用户侧的目标业务的第i对数据包的相对抖动值为T’ u，i+1-T’ u，i-J u，i。

上述将第二传输特征参数与第三传输特征参数进行比较来评价网络质量的原因是(以下以TCP数据速率值为例进行说明，其他通信协议类型以此类推)：
根据TCP数据传输的特点，服务器端下发数据包后，在客户端发送确认字符(ACK，ACKnowledgement)报文后才会继续下发数据包。若客户端出现ACK报文不能及时上传的情况，则服务器端会停止下发数据包，尝试重新与客户端建立连接，从而使得用户体验欠佳。因此，在以TCP数据为主要流量的用户使用场景下，若网络总速率值和TCP数据速率值差别较大(即第二传输特征参数和第三传输特征参数之差的绝对值大于或等于第三预设阈值)，则说明当前设备出现了转发故障。

本领域普通技术人员可以理解，上文中所公开方法中的全部或某些步骤、系统、装置中的功能模块/单元可以被实施为软件、固件、硬件及其适当的组合。在硬件实施方式中，在以上描述中提及的功能模块/单元之间的划分不一定对应于物理组件的划分；例如，一个物理组件可以具有多个功能，或者一个功能或步骤可以由若干物理组件合作执行。某些物理组件或所有物理组件可以被实施为由处理器，如中央处理器、数字信号处理器或微处理器执行的软件，或者被实施为硬件，或者被实施为集成电路，如专用集成电路。这样的软件可以分布在计算机可读介质上，计算机可读介质可以包括计算机存储介质(或非暂时性介质)和通信介质(或暂时性介质)。如本领域普通技术人员公知的，术语计算机存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、程序模块或其它数据)的任何方法或技术中实施的易失性和非易失性、可移除和不可移除介质。计算机存储介质包括但不限于RAM、ROM、EEPROM、闪存或其它存储器技术、CD-ROM、数字多功能盘(DVD)或其它光盘存储、磁盒、磁带、磁盘存储或其它磁存储器、或者可以用于存储期望的信息并且可以被计算机访问的任何其它的介质。此外，本领域普通技术人员公知的是，通信介质通常包含计算机可读指令、数据结构、程序模块或者诸如载波或其它传输机制之类的调制数据信号中的其它数据，并且可包括任何信息递送介质。
本文已经公开了示例实施例，并且虽然采用了具体术语，但它们仅用于并仅应当被解释为一般说明性含义，并且不用于限制的目的。在一些实例中，对本领域技术人员显而易见的是，除非另外明确指出，否则可单独使用与特定实施例相结合描述的特征、特性和/或元素，或可与其它实施例相结合描述的特征、特性和/或元件组合使用。因此，本领域技术人员将理解，在不脱离由所附的权利要求阐明的本申请的范围的情况下，可进行各种形式和细节上的改变。
