Arion v0.2.0 release Pre-release
Pre-release

Open-Source Plan for v0.2.0 Release

Tentative date: 10/10/2022
Release: Arion v0.2.0
Release link: TBD

Release Summary

  • Background

  • Highlights of features and performance

    • Arion DP
      • Designed and implemented e2e DP notification mechanism which supports transmitting OAM information through Data Plane
      • Achieved near direct CN-CN Redis application benchmark throughput (94+% for small packet size, 96%-110% for larger packet size)
    • Arion CP
      • Designed and implemented state reconciliation between ArionAgent and ArionMaster, to provide data consistency and module robustness
      • Achieved ~40us per neighbor from goal state update received in server to end device programming. Including server db writing and notification latency, server to agent state transmit latency and agent programming latency
    • Arion E2E deployment and test
      • Enabled Arion E2E environment (CN + gateway) deployment and sanity test, please refer to Document

Feature Development

  • Arion DP
  • Arion Master
    • Multi level (group, vpc and goalstate) version management (PR#9)
    • Bug fix of vni in neighbor goal state (PR#6)
  • Arion Agent State Reconciliation (PR#2)
    • Local DB integrated, to provide version control and millions of records for fast local lookup in future (PR)
    • Background DB writer, to not slow-down goal state processing (PR)
    • Concurrent map for multi goal state version control (PR)
    • Retrieve LKG revision for reconciliation (PR)

Performance & Scalability

  • Arion DP
    • Achieved near direct CN-CN Redis application benchmark throughput (94+% for small packet size, 96%-110% for larger packet size)
    • Minimal cost for turning on DP notification at Arion DP (<3% in throughput)
  • Arion CP
    • Achieved ~40us per neighbor from goal state update received in server to end device programming. Including server db writing and notification latency, server to agent state transmit latency and agent programming latency

Fundamental

  • Arion Master
    • Add server benchmarking test tool (PR#10)
  • Arion gateway deployment service
    • Add multi-wings deployment support (PR#2)
    • Fixed virtual IP in-balanced allocation issue for better load balancing (PR#7)
  • E2E test controller
    • Add E2E test ability of Arion modules with CN (PR#749)

      • Achieved close to line-speed XDP packet forwarding
    • Arion CP programming latency
      • Achieved 1 million endpoints E2E programming
      • Achieved latency of small-sized configuration <20us per state (1 < state size < 100)
      • Achieved latency of large-sized configuration <10us per state (100 < state size < 1 million)

Feature Development

  • Arion DP
    • XDP/eBPF based packet processing and L2 forwarding
