Supports xDS protocol to communicate with the Control Plane of Service Mesh

[daizhenyu]

Value

Sermant is a Proxyless Service Mesh Solution with better performance.The support for the xDS protocol enables Sermant to better integrate into the Cloud Native Ecosystem. In Istio, Sermant can replace Envoy as the data plane to obtain directly the configuration of the control plane, and avoid performance loss and architecture complexity caused by Sidecar containers.

Objective

Sermant can connect to the control plane of Istio through the xDS API interface to obtain the configurations of CDS, EDS, LDS, and RDS, and parse configurations to data model of the Sermant. Sermant will implement gradually capabilities such as service discovery and route configuration, and the the host microservice can implements the Proxyless Mesh capability by mounting Sermant to invoke directly the upstream service registered with the control plane, such as istiod.
