Comprehensive and Detailed In-Depth Explanation:
ThegRPC-based telemetry protocolutilizesprotocol buffers (.proto files)to define the structure and data format used in communication between a client and a server. In Huawei's telemetry architecture, these files are categorized based on their roles in the data model.
1. RPC Layer:
File:huawei-grpc-dialin.proto
TheRPC layer (Remote Procedure Call layer)handles communication between the client and server.
The filehuawei-grpc-dialin.protodefines thegRPC service interfaces, message structures, and procedures for remote method invocation.
It is essential forestablishing communicationandinvoking telemetry data collection.
Function:Managesdial-in and dial-out connectionsbetween the telemetry client and the server.
2. Telemetry Layer:
File:huawei-telemetry.proto
Thetelemetry layeris responsible forcollecting, packaging, and exporting telemetry data.
The filehuawei-telemetry.protocontains thedata modelused for telemetry reporting, includingstreaming data formatsandtelemetry messages.
It defines how thecollected datais organized and transmitted.
Function:Provides astructured way to export telemetry datain real-time or batch mode.
3. Service Data Layer:
File:huawei-debug.proto
Theservice data layercontains data models related todiagnostics, debugging, and operational data.
The filehuawei-debug.protois used tocollect debugging informationfrom network devices.
This file is crucial fortroubleshooting and monitoring the healthof the system.
Function:Facilitatesdebugging and diagnostic telemetry data collection.
Why This Mapping Is Correct:
The mapping is based on thefunctional role of each layerand thepurpose of each .proto filein the Huawei gRPC-based telemetry architecture.
Correctly identifying the file location is crucial foreffective telemetry configurationanddata collection.
