Sedna communication problem

[SherlockShemol]

这是Sedna的架构图。 Sedna中提到其提供EdgeMesh的跨边缘-云微服务发现和数据平面流量治理功能。请问图中的Messaging over Kubeedge是通过EdgeMesh实现的吗？源代码的这部分好像直接用websocket实现了，没有用到edgemesh？（抱歉代码水平有限） 还请您不吝赐教。

This is the architecture diagram of Sedna. Sedna mentioned that it provides EdgeMesh's cross-edge-cloud microservice discovery and data plane traffic management functions. Is the Messaging over Kubeedge in the picture implemented through EdgeMesh? This part of source code seems to be implemented directly using websocket without using edgemesh? (Sorry for the limited code level) Please feel free to give me some advice.
