gRPC

A high-performance open-source RPC framework that uses HTTP/2 transport and Protocol Buffers serialization.

Definition

gRPC supports unary, server streaming, client streaming, and bidirectional streaming calls, with code generated from .proto service definitions. It is used for microservices and for network telemetry and configuration via gNMI.

Example

A gNMI client opens a bidirectional streaming Subscribe RPC to a router over gRPC.

Exam tip

gRPC = HTTP/2 + Protobuf; it is binary and efficient, unlike JSON over HTTP/1.1 REST.
