Description

网络设备的数据采样方法、装置、设备及介质 技术领域
本申请涉及通信技术领域，例如涉及一种网络设备的数据采样方法、装置、设备及介质。
背景技术
随着第五代移动通信系统(the 5th Generation mobile communication system，5G)时代的到来，运营商配置管理接口的兴起，数据流量呈指数增长，网络所承载的业务也逐渐趋向于多元化，这对电信传输设备的可维护性和监控性能提出了更高的要求。其中，网络设备的性能、告警、状态等的统计采样会达到每秒最高100次。
传统的报文统计采样方式是：在报文经过网络设备时，由网络设备的网络处理器(Network Processing Unit，NPU)进行报文统计，并由NPU将统计的多项统计值存储在NPU的存储器中，再由设备的中央处理单元(Central Processing Unit，CPU)定时向NPU发送查询消息，定时采样获取的统计值(如图1所示)，并在处理后呈现到人机界面。但是，在查询项目过多时CPU需要处理成倍的查询消息，严重消耗了CPU的处理资源，以及CPU到NPU之间的配置查询通道带宽。针对高达10ms-100ms的采样要求，CPU在短时间内无法处理如此多的消息，即使有高性能CPU能够处理如此多的消息也会消耗高性能CPU的大量的处理资源，而且高性能CPU的价格十分昂贵。

在一示例中，平均值可以指周期内所有采样值的平均值。
在另一示例中，平均值可以指周期内最大采样值和周期内最小采样值的平均值，即最大最小平均值。

采样值报告计数值从初始值开始(例如是从1开始)，如果采样值报告计数值不等于采样值报告间隔，则协处理器发送的下一个采样指示报文中的采样值报告计数值递增1，如果采样值报告计数值等于采样值报告间隔，则协处理器发送的下一个采样指示报文中的采样值报告计数值重新设置为初始值(即为1)。
当所述报告间隔为平均值报告间隔时，所述报告计数值为平均值报告计数值；对所述平均值报告间隔不为零的采样功能项，在依次发送的所述采样指示报文中，所述平均值报告计数值由初始值依次递增，增至所述平均值报告间隔时重置为所述初始值。
如果采样功能项对应的平均值报告间隔不为0(平均值报告间隔为0表示不需要进行平均值报告)，则采样指示报文中的平均值报告计数值从初始值开始(例如是从1开始)，如果平均值报告计数值不等于平均值报告间隔，则协处理器发送的下一个采样指示报文中的平均值报告计数值递增1，如果平均值报告计数值等于平均值报告间隔，则协处理器发送的下一个采样指示报文中的平均值报告计数值重新设置为初始值(即为1)。
设置报告计数值的意义在于，NPU不具备计时计数功能，不知道什么时候向CPU发送采样报告报文，通过采样指示报文中的报告计数值的设置，NPU可以通过比较采样指示报文中的报告计数值和报告间隔，确定出是否需要向CPU发送采样报告报文。
在另一示例中，所述采样指示报文中携带报文类型、采样编号、采样功能项、报告计数值、报告间隔、抑制冗余标识。
抑制冗余标识，用于指示NPU在抑制冗余标识为有效值时，实现冗余抑制功能。NPU在实现冗余抑制功能时，如果当次采样数据发生变化，则立即向CPU上报，如果当次采样数据没有发生变化，则按照报告间隔向CPU上报。
在一示例中，所述采样指示报文中还包括：采样功能项总数量，所述采样功能项总数量用于指示所述采样指示报文中包括的采样编号以及采样功能项的组数量；不同组中的采样功能项的采样频率和报告间隔均相同。
如果多个采样功能项是关联的，具有相同的采样频率和报告频率，则可以同时进行配置，进而，协处理器可以在一个采样指示报文中携带多个采样功能项，并在该采样指示报文中携带采样功能项总数量。
所述采样指示报文中包括的采样编号以及采样功能项的组数量为至少一组。当采样指示报文中只携带一个采样功能项时，采样功能项总数量为1。
在一具体示例中，表2中示出了一种采样指示报文包含的字段信息。

NPU，是网络设备的核心器件，具有一定的编程能力，能对网络报文进行高速处理，在本申请中，NPU接收协处理器发送的报文之后，会对多种报文进行统计分析。
NPU内部有多个统计寄存器、告警寄存器、状态寄存器，对应不同的统计功能项、告警项、状态项，指示当前的网络和设备的统计、告警和状态。
另外，NPU能访问读写一片内存空间，可以称之为采样内存空间，采样内存空间设置为存储采样值。在一具体示例中，表3中示出了采样内存空间的一种采样值存储表，其中，平均值可以是最大最小平均值。下述均以平均值是最大最小平均值为例进行解释说明，也即下文中提到的平均值均可以是最大最小平均值。

在一示例中，通过NPU根据所述采样指示报文生成所述目标数据的采样报告报文，可以为：
通过NPU根据所述采样指示报文，更新本地存储的采样值；当所述采样指示报文中的所述报告计数值等于所述报告间隔时，根据本地存储的采样值生成所述目标数据的采样报告报文；其中，所述采样报告报文包括采样值报告报文和/或平均值报告报文。
NPU根据接收到的采样指示报文中的字段，将对应寄存器中的采样值按照序列搬移到采样内存空间中，可以是添加至如表3所示的采样值存储表中，采样值存储表中的采样值用于填充采样报告报文。
为了便于计算周期内数据平均值，NPU根据接收到的采样指示报文中的字段，将对应寄存器中的采样值按照序列搬移到采样内存空间中之后，可以对与采样编号匹配的周期内最大值和周期内最小值进行更新。进而，在需要上报平均值时，直接根据如表3所示的采样值存储表中与采样编号匹配的周期内最大值和周期内最小值进行计算即可。平均值为周期内最大值和周期内最小值的平均值。
同时，NPU通过比较采样指示报文中的报告计数值与报告间隔，判断是否已到采样报告报文发送周期。
如果采样指示报文中的采样值报告计数值与采样值报告间隔不相等，则说明未到关于采样值的采样报告报文发送周期；如果采样指示报文中的采样值报告计数值与采样值报告间隔相等，则说明已到关于采样值的采样报告报文发送周期，进而NPU生成对应的采样报告报文发送至CPU。
如果采样指示报文中的平均值报告间隔为零，则说明不需要进行平均值上报；如果采样指示报文中的平均值报告间隔不为零，则说明需要进行平均值上报，如果采样指示报文中的平均值报告计数值与平均值报告间隔不相等，则说明未到关于平均值的采样报告报文发送周期；如果采样指示报文中的平均值报告计数值与平均值报告间隔相等，则说明已到关于平均值的采样报告报文发送周期，进而NPU生成对应的采样报告报文发送至CPU。
在另一示例中，通过NPU根据所述采样指示报文生成所述目标数据的采样报告报文，可以为：
当所述采样指示报文中所述抑制冗余标识为有效值时，通过NPU根据所述采样指示报文，更新本地存储的采样值，并判断当前时刻采样值是否发生变化；通过NPU如果确定所述当前时刻采样值发生变化，则根据本地存储的采样值生成所述目标数据的采样报告报文；通过NPU如果确定所述当前时刻采样值未发生变化，则当所述采样指示报文中的所述报告计数值等于所述报告间隔时，根据本地存储的采样值生成所述目标数据的采样报告报文，并发送至CPU；其中，所述采样报告报文包括采样值报告报文和/或平均值报告报文。
当所述采样指示报文中所述抑制冗余标识为有效值时，NPU根据所述采样指示报文，更新本地存储的采样值，并判断当前时刻采样值是否发生变化：如果所述当前时刻采样值发生变化，则根据本地存储的采样值生成所述目标数据的采样报告报文，并发送至CPU；如果所述当前时刻采样值未发生变化，则当所述采样指示报文中的所述报告计数值等于所述报告间隔时，根据本地存储的采样值生成所述目标数据的采样报告报文，并发送至CPU。
在判断当前时刻采样值是否发生变化时，对于统计值而言，如果当前时刻采样值不为零即认为当前时刻采样值发生了变化，对于告警值和状态值而言，如果当前时刻的采样值与前一时刻的采样值不一致即认为当前时刻采样值发生了变化。进而，在抑制冗余标识为有效值时，如果当前时刻采样值发生了变化，NPU则立即向CPU发送采样报告报文，如果当前时刻采样值未发生变化，NPU则到报告周期时才向CPU发送采样报告报文。
在一具体示例中，表4中示出了一种关于采样值的采样报告报文包含的字段信息。
