Description

一种 PTN 网络业务流量管理的方法 技术领域
本发明涉及网络业务流量的管理，具体说是一种PTN网络业务流量管理的方法。
背景技术
分组传送网（PTN）是基于分组交换的、面向连接的传送技术，可以承载各种业务，满足高可靠性、严格服务质量和运行管理维护（OAM）等基本特性。但是，PTN的基本特性没有提出实时的业务流量管理方法。于是，一种新的PTN网络设备端口的实时流量管理方法被提了出来。
经过对已有专利进行检索，我们没有发现PTN网络业务流量管理的相关专利。
与本发明要求最接近的在先专利《一种分时流量管理方法及装置》（其公开号是101056274）记载了一种流量管理方法：预先设置流量时间管理参数，并与需要管理的流相匹配，计时器根据流量时间管理参数，对相应的流执行控制。该发明没有提出实时流量管理，无法反应PTN网络设备端口的实时流量变化。
 发明内容
针对现有技术中存在的缺陷，本发明的目的在于提供一种PTN网络业务流量管理的方法，实现了PTN网络设备端口的实时流量变化的实时监控，可以在任意时间内管理实时流量变化，可以看到从最大流量到最小流量的实时变化。
为达到以上目的，本发明采取的技术方案是：

第1步：在网管服务器中设置某条业务对应端口为采集状态，并设置采集时间间隔以及采集时间段；
第2步：服务器在采集时间段内，按采集时间间隔与被设置为采集状态的端口所在的网元设备进行数据交互，采集被设置为采集状态的端口的实时流量数据，所述实时流量数据包括发送流量TX_FLOW和接收流量RX_FLOW；
第3步：网元设备将实时流量数据返回给服务器，服务器在获取实时流量数据后将其储存在服务器上；

在上述技术方案的基础上，还包括以下步骤：第6步：在网管客户端的显示界面上察看业务实时流量时，网管客户端从服务器端获取对应业务的实时流量数据，并在网管客户端用图形化界面显示端口的实时流量，实时流量是以秒为单位度量数据包的数目，图形化界面采用矢量图的方式显示。
在上述技术方案的基础上，还包括以下步骤：第7步：通过带宽利用率的计算公式得到该条业务的带宽利用率：实时流量/分配带宽×100%，
判断业务带宽利用率是充分或是不足：带宽利用率的取值范围为0到100%，

在上述技术方案的基础上，还包括以下步骤：第8步：当带宽利用率不足，则将该业务分配带宽降低，使带宽利用率处于正常范围内，当带宽利用率过大，则增大该业务的分配带宽，使带宽利用率处于正常范围内。

 具体实施方式
以下结合附图对本发明作进一步详细说明。
本发明公开了一种PTN网络业务流量管理的方法，且本发明所述方法不限制底层的传输技术，可以应用于基于MPLS（Multi-Protocol Label Switching）、T-MPLS（Transport Multi-Protocol Label Switching）以及MPLS-TP（MPLS Transport Profile）的PTN网络以及其它类型的网络。
在如图1所示的网络管理系统中，网管客户端1、服务器（网管服务器）2、若干网元设备3均连接到同一个路由器4上，在网元设备间存在若干条端到端业务。对于不同的端到端业务，当某条业务对应的端口被设置为采集状态，则服务器在预先设置的采集时间内，与被设置为采集状态的端口所在的网元设备进行数据交互，采集被设置为采集状态的端口的发送和接受流量性能数据并将其作为实时流量数据存储；网管客户端与服务器连接获取存储的该条业务的实时流量数据，通过对该条业务的实时流量数据进行图形化显示得到该条业务的实时流量趋势图，实时流量趋势图反映出该条业务的实时流量在某个时间段的变化趋势,由于端到端的业务在业务传输数据时带宽是固定的，因此根据业务带宽与实时流量数据的比较可判断业务带宽利用率是否充分。
PTN网络业务具有分组业务的突发性和统计复用的特点，提供IP/MPLS（IP/Multi-Protocol Label Switching）及以太网承载的手段，为业务的高效管理奠定了基础，本发明基于PTN的分组特性，提出了PTN网络业务流量管理的方法（PTN网络业务的流量监控方法）。其具体步骤如下：
第1步：在网管服务器中设置某条业务对应端口为采集状态，并设置采集时间间隔（1～10秒）以及采集时间段；
第2步：服务器在采集时间段内，按采集时间间隔与被设置为采集状态的端口所在的网元设备进行数据交互，采集被设置为采集状态的端口的实时流量数据，所述实时流量数据包括发送流量（TX_FLOW）和接收流量（RX_FLOW）；
例如：服务器通过后台服务调用与网元设备连接网卡，向网元设备发送UDP命令获取实时流量数据；
第3步：网元设备将实时流量数据返回给服务器，服务器在获取实时流量数据后将其储存在服务器上；
第4步：网管客户端的工作流程如图2所示，首先网管客户端从服务器获取网元设备的名称，然后再从服务器获取被设置为采集状态的端口名称，最后网管客户端从服务器获取已采集实时流量数据的业务的源端口和宿端口；
第5步：网管客户端在显示界面上显示已采集实时流量数据的PTN网络中端到端业务；
所述已采集实时流量数据的PTN网络中端到端业务可以是不同级别的通道业务；网管客户端的显示界面可参见图3，至少包括：业务名称、源网元、源LAN口、源PW标签、宿网元、宿端口、宿PW标签、监控间隔、监控状态、各业务具体的实时发送流量及实时接收流量。
在上述技术方案的基础上，还包括以下步骤：
第6步：在网管客户端的显示界面上察看业务实时流量时，网管客户端从服务器端获取对应业务的实时流量数据，并在网管客户端用图形化界面显示端口的实时流量，实时流量是以秒为单位度量数据包的数目，图形化界面采用矢量图的方式显示。
如图4所示，通过查看实时流量的图形化界面可以得知流量的变化趋势。流量趋势反映了端口的接收流量和发送流量随时间变化的趋势。图形化的方式能很直观的观察到指定时间段内接受流量最小值，最大值，发送流量最小值，最大值，并且图形化显示能很清楚地查看指定时间段实时流量的变化趋势，得到实时流量数据是属于上升状态还是属于下降状态。
在上述技术方案的基础上，还包括以下步骤：
第7步：通过带宽利用率的计算公式得到该条业务的带宽利用率：实时流量/分配带宽×100%，
判断业务带宽利用率是充分或是不足：带宽利用率的取值范围为0到100%，
若带宽利用率长时间处于0～30%，则可认为该业务带宽利用率不足，若带宽利用率长时间处于90%～100%则可认为该业务带宽利用率过大，若带宽利用率处于30%～90%则可认为该业务带宽利用率正常。
由于对于端到端的业务在创建时已经分配好带宽，所以通过分配带宽与实时流量的比较可以判断业务带宽利用率是充分或是不足，得到该条业务的带宽利用率。
在上述技术方案的基础上，还包括以下步骤：
第8步：当带宽利用率不足，则将该业务分配带宽降低，使带宽利用率处于正常范围内，当带宽利用率过大，则增大该业务的分配带宽，使带宽利用率处于正常范围内。
