[Valkyrie网络测试仪-软件使用技巧] - Scheduler动作录制，定制打流过程（中途启停/调整带宽/使能部分流量）

在UI界面下将脚本的事情就做完了！ -- ValkyrieManager Scheduler

在网络测试打流过程中，我们经常会遇到要对比在不同报文长度下，端口的转发性能是否有影响，改变报文长度，对转发系统的延迟处理会带来多大的影响，需要实施动态的流量压力测试，并根据实际的场景，可能需要规划模拟某些流量进行定时定次的发送等场景，传统的解决方法是直接拿API进行脚本调取进行二次开发，学习起来比较费事，ValkyrieManager的Scheduler功能可以很好的解决以上痛点。

Xena Scheduler可以在打流过程中进行动态的参数调整，实现动态流量模型，如变更发包的报文长度Packet length，发包的带宽Rate/PPS，动态的启停某些流量等

Scheduler界面设定

默认该页面在最下面折叠了，方便查看，可以将它先右上角固定住，再拖动到与其他常用界面齐平

Scheduler支持设定的动作

Set parameter value改变流数据参数（指定来了的PPS/Rate%数据）
Wait period插入等待时间
Start traffic开启端口发包
Stop traffic停止端口发包
Clear Statistics统计数据清零
Enable Stream使能流量
Disable Stream禁用流量
Suspend暂停流量
Custom Port/ Stream Command自定义命令行数据（端口级别/流级别）

范例1，动态调整发包带宽-改变Rate/PPS

测试过程中调整带宽，用于观察带宽增加或降低速率时，接受端口的Rx数据，Rx Latency等数据变化

范例2，动态调整发包带宽-Multi-Streams多流之间调度

Suspend暂停<-->Enable启用，状态之间切换

Stream有3种状态，Enable启用/Disable禁用/Suspend暂停

在端口发包的时候，Stream状态可以在Suspend/Enable之间切换

Suspend的Stream会占用该端口下的流设定带宽，但发包的时候不会发送
