|
|
|
|
|
|
1、下发Shaping Rule如下图所示：

2、访问地址：[https://ubuntu.com/download/desktop/thank-you?version=24.04&architecture=amd64<s=true] 下载镜像
|
|
|
|
|
|
|
|
|
|
|
|
当前问题如下图所示：流量大部分为Incoming流量，配置的Incoming的速率为7.5Mbps，当前为18Mbps，与预期值相差较大

Bug中使用的profile为SplitBy，观察Profile的命名，是否该Profile之前的限速值为20Mbps？ [~hebingning]

在进行此测试之前10分钟将限速值由20Mbps改为7.5Mbps

问题原因推测：
|
|
|
|
|
|
* 通过界面配置Shaping Profiles后，Swarmkv_Sentinel会调用FTCFG命令为Profile创建相应的Token的key。当Shaping首次接收到流量时，会在本地创建路由信息，并将FTCONSUME命令通过远程方式发送给Swarmkv_Sentinel并触发同步消息，从而在本地创建这些key的副本。当界面修改Shaping Profiles后，Swarmkv_Sentinel会执行DEL命令删除key和FTCFG命令再次创建key，由于Shaping中存在副本，Swarmkv需要同步DEL和FTCFG消息，然而，由于当前环境中存在大量的同步消息，这导致了此次Swarmkv的同步请求出现了超时。因此，Shaping无法及时获取到最新的key配置信息，而是维持了之前key的配置。
