Flexible ASIC-Based OpenFlow Pipeline Tool for HPE Aruba Switches

Learn how to construct flexible ASIC tables for OpenFlow pipelines on HPE Aruba switches using the ovs2json tool. Extract match fields, read flows from OVS, and define pipelines via GUI or OFPMP_TABLE_FEATURES request.

Presentation Transcript

  1. Flexible ASIC-based OpenFlow pipeline Shaun Wackerly, HPE Aruba <wackerly@hpe.com>

  2. Overview Flexible ASIC tables Tools ovs2json pipeline constructor How it’s done in FAUCET

  3. HPE Aruba 6th generation ASIC • 5400Rv3 • 3810 • 2930 • Table types • TCAM, wildcardable (up to 8K entries) • Hash, exact-match (up to 64K entries) • Reconfigure pipeline at run-time • No reboot, OF disable, firmware change, or licensing needed Flexible ASIC tables

  4. Read flows from OVS • extract match fields & entry counts • produce JSON pipeline definition • Use case • have existing application or solution implemented virtually (OVS) • want to deploy on HPE Aruba switches for scale/performance Tool: ovs2json

  5. Construct pipeline via GUI • table size • table ordering • match fields/type All actions are automatically included • Use case • have idea for application • want to speculate if implemented (at scale)on an HPE Aruba switch Tool: Pipeline constructor

  6. OFPMP_TABLE_FEATURES request** • Empty body: Read pipeline • Full body: Define pipeline • In the code: • faucet/valve.py – Identifies switch type, verifies pipeline • faucet/tfm_pipeline.py - Parse JSON & define pipeline • Parse JSON file (LoadRyuTables.load_tables) • Send to switch (valve_of.table_features) ** OpenFlow 1.3.5 spec, section 7.3.5.5 How it’s done in FAUCET

  7. Thank you Shaun Wackerly, HPE Aruba <wackerly@hpe.com>
