                Use cases for gRPC in network management
                  draft-talwar-rtgwg-grpc-use-cases-01

Abstract

   gRPC is an open, high-performance RPC framework designed for
   efficient low-latency cross-service communications.  This document
   describes use cases for gRPC in network management and other
   services, particularly streaming telemetry.

1.  Introduction

   gRPC is a high performance universal RPC framework to connect
   distributed systems [GRPC-WWW].  gRPC emerged from an internal Google
   framework called Stubby which has been used to connect large numbers
   microservices running within and across data centers for over a
   decade.  Having a uniform, cross-platform RPC infrastructure allowed
   Google to deploy fleet-wide improvements in efficiency, security,
   reliability and behavioral analysis critical to supporting the
   incredible growth of these services.  gRPC is the next generation of
   Stubby, built in the open originally for services, as well as last
   mile computing use cases like mobile, browser, IOT [GRPC-DESIGN].  It
