Description

一种在分组传送网中进行信号劣化状态检测的方法及装置 技术领域
本发明涉及分组传送通讯领域，尤其涉及一种在分组传送网中进行信号劣化状态检测的方法及装置。
背景技术
在电信业务的IP化趋势的推动下，传统的面向TDM业务设计的SDH传输网技术和基于SDH(Synchronous Digital Hierarchy，同步数字体系)的多业务传送平台技术(MSTP，Multi-Service Transfer Platform)都无法满足以当前分组业务为主的应用需求，分组传送网成为新的选择。分组传送网支持多种基于分组交换业务的双向点对点连接通道，具有适合各种粗细颗粒业务、端到端的组网能力，提供了更加适合于IP业务特性的“柔性”传输管道；点对点连接通道的保护切换可以在50毫秒内完成，可以实现传输级别的业务保护和恢复；继承了SDH技术的操作、管理和维护机制(Operation Administration and Maintenance，简称为OAM)，具有点对点连接的完整OAM，保证网络具备保护切换、错误检测和通道监控能力；完成了与IP/MPLS多种方式的互连互通，无缝承载核心IP业务；网管系统可以控制连接信道的建立和设置，实现了业务QoS的区分和保证等诸多优点。
在分组传送网中，路径信号劣化是OAM的重要特性，而信号劣化的检测主要采用通过专门的OAM报文(比如TP-MPLS OAM的LM报文)、业务报文以及在没有业务报文的路径中插入背景流等方式，然后计算报文的收发报文数计算得出，对于不同的应用场景，需要选择不同的信号劣化检测方式来处理，而无法实现通过一种方式来针对多种不同场景的信号劣化检测。

其中所述J为由于报文的时延抖动带来的报文接收数量的估计误差，S为误码率，D为CCM的当前发包速率。
所述信号劣化状态检测门限为[L+X，L-X]，L为检测周期内的理论丢包数，X为调整值。
所述调整值X如下：
X＝J+L×A，A为调整系数，0≤A<1；
当所述实际丢包数量大于最大信号劣化状态检测门限值时，进入信号劣化状态；
当所述实际丢包数量小于等于最小信号劣化状态检测门限值时，退出信号劣化状态；
当所述实际丢包数量小于等于最大信号劣化状态检测门限值且大于最小信号劣化状态检测门限值时，维持当前状态。
为了更好地说明本发明实施例的意图，下面以一个应用示例进行阐述。
在两个网元设备间配置一条隧道，同时为他们配置了OAM，并对配置的隧道进行监控。
该两个网元设备间CCM的发送/接收，会因为报文的抖动造成接收CCM数的变化，从而造成丢包数的计算误差，假设时延抖动为10ms，则在发送周期为3.3ms时丢包数的估计误差值为J。为了保证计算的正确性和精确度，要求理论丢包数应大于2J，则根据公式：理论丢包数＝误码率×发包速率×时 间门限值>2×J，可以得到时间门限值，具体如下表1所示。
表1
  10－2 10－3 10－4 10－5
3.3×10-3 10 20 200 2000
10×10-3 10 30 300 3000
100×10-3 30 300 3000 30000
在上述表格中，第一横排为已知的误码率，第一纵排为CCM发送周期。对于该表格中的每个时间门限值，均为取10的整数倍后的值，单位为秒。
在本发明实施例中，由于发送周期为3.3ms，选取的误码率为10－3，故根据上述表格对应的该时间门限值为20s。
根据上述公式以及表格记载，不难发现，当CCM的误码率以及CCM的时延抖动固定时，CCM的发包速率越大，时间门限值越小；当CCM的发包速率以及CCM的时延抖动固定时，CCM报文的误码率越大，时间门限值越小；当CCM的误码率以及CCM报文的发包速率固定时，CCM报文的时延抖动越大，时间门限值越大。
由于确定了时间门限值，为了能够在检测周期内采集到足够数量的CCM用于信号劣化状态判断，故对于检测周期的设置需要使其大于或等于该预定的时间门限值。
在设置完检测周期后，需要在该检测周期内获取CCM报文的实际丢包数量。其中，在计算该实际丢包数时，可以通过如下公式：
期望接收CCM数＝CCM检测周期/CCM发包周期
实际丢包数＝期望接收CCM数–实际接收CCM数
上述的实际接收CCM数即为在该检测周期所接收到的CCM数量。
在得到实际丢包数后，为了确定当前是否进入信号劣化状态，确定信号劣化状态检测门限。
其中，在确定信号劣化状态检测门限之前，还先确定检测周期内的理论丢包数，确定公式为：理论丢包数＝误码率×发包速率×检测周期。
为了容忍误差，防止抖动，通过采用高低信号劣化状态检测门限的方式来确定信号劣化状态。
可选地，首先确定高低信号劣化状态检测门限的调整值，该调整值X可 以等于J+L×A，A为调整系数，0≤A<1，J为由于报文的时延抖动带来的报文接收数量的估计误差。
可选地，当A为0时，该调整值X等于J，即在检测周期内并未发生任何的丢包问题；当A为0＜A<1时，说明在检测周期内发生了不同程度的丢包现象。
可选地，根据确定的调整值即可得到该信号劣化状态检测门限的高低门限值，即[L+X，L-X]。
在得到信号劣化状态检测门限的高低门限值后，根据该高低门限值以及检测周期内的实际丢包数来确定是否进入信号劣化状态。
可选地，当所述实际丢包数量大于最大信号劣化状态检测门限值时，进入信号劣化状态；
当所述实际丢包数量小于等于最小信号劣化状态检测门限值时，退出信号劣化状态；
当所述实际丢包数量小于等于最大信号劣化状态检测门限值且大于最小信号劣化状态检测门限值时，维持当前状态。
本发明实施例还提供了一种在分组传送网中进行信号劣化状态检测的装置，如图2所示，该装置包括处理模块21，获取模块22以及确定模块23；
其中，处理模块21，配置为设置信号劣化状态检测的检测周期。
获取模块22，配置为获取所述检测周期内CCM的实际丢包数量。
确定模块23，配置为根据所述获取模块获取的实际丢包数量与信号劣化状态检测门限确定是否进入信号劣化状态；可选地，当所述实际丢包数量大于最大信号劣化状态检测门限值时，确定进入信号劣化状态；当所述实际丢包数量小于等于最小信号劣化状态检测门限值时，确定退出信号劣化状态；当所述实际丢包数量小于等于最大信号劣化状态检测门限值且大于最小信号劣化状态检测门限值时，确定维持当前状态。
可选地，处理模块21设置的所述检测周期大于或等于预定的时间门限值，使得所述获取模块22能够在所述检测周期内能够采集到足够数量的CCM用于所述确定模块23对信号劣化状态判断。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计 算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
上述实施例中的各装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的各装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
