Schema

Introducing the InfraGraph (INFRAstructure GRAPH) schema

A graph is a natural fit to describe a system of systems in a clear, intuitive, and mathematically precise manner.

• Node or vertex represents an entity like a component, device, user, router, etc
• Edge represents a relationship between nodes
• Properties store additional information about nodes or edges

Principles

InfraGraph is a collection of APIs and Models used to describe AI/HPC infrastructure based on the following core principles:

• infrastructure can be described using graph concepts such as vertexes, edges and properties
  • vertexes can be component or device instances
  • an edge contained by a device subgraph is 2 component instances separated by a link
    • e.g., npu.0.pcie.nic.0
  • an edge contained by the infrastructure is 2 device connections separated by a link where a device connection is the device instance name and index and external component name and index
    • e.g., server.0.nic.0.eth.leafsw.0.port.0
  • a path is a collection of infrastructure and device connections between a single source and destination
  • properties are fields with in the device and component objects
• devices are composable using connections
• connections dictate the depth of the graph
• infrastructure and device connections dictate the shape of the graph
• infrastructure needs to be scalable without duplicating content

OpenapiArt

This repository makes use of OpenAPIArt to do the following:

• create declarative intent based Models and APIs
• auto-generate the following artifacts:
  • openapi schema
  • protobuf schema
  • Redocly documentation of APIs and Models
  • Python/Go SDKs that allow for creating fluent client/server code over REST/Protobuf transports
