What do the abbreviations mean?

Could you tell me what the abbreviations mean СDS, LDS, RDS, ECDS? Where you can read about them

[root@m1 temp]# istioctl proxy-status
NAME                                 CLUSTER        CDS          LDS        EDS          RDS          ECDS         ISTIOD                     VERSION

Thank you.

I found this information while searching, it is taken from book "Istio In Action":
CDS: Cluster Discovery Service
LDS: Listener Discovery Service
EDS: Endpoint Discovery Service
RDS: Route Discovery Service
ECDS: Envoy Cluster Discovery Service

Some blogpost including it:

Just a side note - this is more of a question for the main Istio team, not the Kiali team. Those are related to the envoy proxy and nothing to do with Kiali.
