DRA Chainable Networking Proposal

Mon, 01 Jan 0001 00:00:00 +0000

DRA Chainable Networking

A proposal for declarative, composable network configuration in Kubernetes using DRA device requests with dependOn chaining — enabling bonding, VLANs, tuning, and mixed NIC + GPU topologies in a single ResourceClaim.

Constraint: this proposal uses only the existing DRA API (DeviceClass, ResourceClaim, ResourceSlice, opaque config). No upstream API extensions are required.

1. Problem Statement

Today’s DRA network drivers face a fundamental limitation: complex network topologies cannot be expressed declaratively within the DRA API.

DRA Network Device Discovery and ResourceSlice Design

Status: Selected Design
Companion documents: DRA Chainable Networking Proposal | Discovery Brainstorm
Upstream dependencies: KEP 4815 — SharedCounters (GA, K8s 1.35+) | KEP 5075 — Consumable Capacity (Beta, K8s 1.36) | KEP 5941 — Shared Consumable Capacity | KEP 5491 — DRAListTypeAttributes (Alpha, K8s 1.36)

1. Overview and Design Principles

This document specifies how the DRA network driver discovers host network devices and publishes them as ResourceSlices for scheduler-aware allocation.
