2022 LFN Workshop - Deep Dive on Interop Challenges

Topic Leader(s)

• @Scot Steele

Topic Description

Topic Overview

• Deep Dive: Interoperability Challenges

  • Part 4: CNF Interoperability Challenges between workload/platform and orchestrator/workload

  •  

    • CNI – is this the only answer?

    • Other networking frameworks (eg., Istio, Envoy)?

    • Networking abstraction – how do we push this past the goal line, publish, and test?

    • Data Plane

      • If performance tuning is a source of interop issues, how do we address these?

      • Are data plane issues as opaque to workloads as claimed (should we do a survey, or testing experiment to have non-anecdotal data)?

what does it take  for the function to interoperate with the platform?

CNI in it's current form is not the answer

Platforms should support an option to allow for other networking interfaces

Are there to many solutions? 

Is there a DeFacto standard? CNI is but it doesn't support all of the needed functions

Kubernetes - V4/V6

Some plugins have addressed (e.g. Multus)

Multi pod interfaces where all interfaces are equal

Would a project focused on the issue (ref: Doctor from OPNFV) If so it would likely be under Anuket

Multi-homed requirements needed for Telco

• Exploratory project created by @Victor Morales - Samsung  - https://github.com/gw-tester/

  @Scot Steele to collaborate with Ashiq Khan and Riota Tetsuya on exploratory project created by Victor Morales - Samsung https://github.com/gw-tester/

• CNF-WG is working on best practices for CNFs. Work is organized by use cases - https://github.com/cncf/cnf-wg/tree/main/use-case

Nodus: https://github.com/akraino-edge-stack/icn-nodus

Can it support needed?

Review of Doctor project on collaboration - 

Other networking frameworks (eg., Istio, Envoy)?

Networking abstraction – how do we push this past the goal line, publish, and test? No feedback

• Data Plane

  • If performance tuning is a source of interop issues, how do we address these?

    • anecdotal information indicated however seems to be solved by the DP platform selected

    • Can RA-2 specify performance? if not, where?

  • Are data plane issues as opaque to workloads as claimed (should we do a survey, or testing experiment to have non-anecdotal data)?

• Service Mesh discussion - Olivier - 

• Nodus can support SFC
