slide1. Latest P4 features and bug fixes towards R5 Georgios P. Katsikas, TFS TSC member, UBI TFS#6 Plenary Meeting<br>
slide2. P4 development timeline 2 Apr’25 Jun’23 Nov’24 Oct’22 Oct’23 Today TFS HF#1 NetworkX, NL P5 paper at IEEE HPSR TFS HF#3 CTTC, ES P4 intro
Toy demo
1 Mininet BMv2 switch 1st P4 service handler
Simple Port fwd
8 Mininet BMv2 switches
Integration with Policy
External integration with Monitoring Merged into TFS
Presented in HF#3 End of TFS R5 + TFS HF#6 No P4-related commits in TFS
Background work to support In-band Network Telemetry (INT)
Jointly with Jakub+Tomasz from Warsow Univ. Milestone for ETSI SNS4SNS Merged into TFS R5
Presented in HF#6<br>

slide4. Latest P4 developments TeraFlow SDN Template 4 Testing with realistic P4 dataplanes ïƒ SD-Fabric’s fabric-v1model Simplified view Revealed bugs in the P4 driver Bug #1: P4 driver does not correctly retrieve meter and metadata resources (Issue #139) Bug #2: Fix handling of modify() vs. insert() entries (Issue #227) Bug #3: Parse P4 CloneSession entries from JSON (Issue #228) Bug #4: P4 resource keys with unique IDs (Issue #223)<br>
slide5. Latest P4 developments TeraFlow SDN Template 5 Testing with realistic P4 dataplanes ïƒ SD-Fabric’s fabric-v1model Simplified view Required new features Feat #1: Pass P4 device endpoints through init settings (Issue #225) Feat #2: P4 test for INT, routing, and ACL dataplane setup (Issue #226) Feat #3: P4 SBI end-to-end integration test pipeline (Issue #154) Feat #4: Updates in Monitoring to support P4 in-band network telemetry (Issue #116) Feat #5: New P4 Service handler to support end-to-end services with INT (Issue #118)<br>
slide6. Upcoming P4 developments 6 Testing with realistic P4 dataplanes ïƒ SD-Fabric’s fabric-v1model Feat #6: Support for P4-based 5G UPF (Issue #229) Another milestone for<br>
slide7. Summary of P4 developments into R5 TeraFlow SDN Template 7 Bug fixes (at least) 4 New features 6 P4 endpoints support Test for verifying fabric-v1model INT, routing, and ACL capabilities First end-to-end P4 integration test INT collector integration into Monitoring & Telemetry system A new P4 INT service handler Support for P4 5G UPF capabilities More bugs may be potentially uncovered<br>
slide8. Summary of P4 developments into R5 TeraFlow SDN Template 8 P4 endpoints support Test for verifying fabric-v1model INT, routing, and ACL capabilities First end-to-end P4 integration test INT collector integration into Monitoring & Telemetry system A new P4 INT service handler Into develop by the end of November 2024 Support for P4 5G UPF capabilities Bug fixes (at least) 4 New features 6<br>
slide9. Summary of P4 developments into R5 TeraFlow SDN Template 9 P4 endpoints support Test for verifying fabric-v1model INT, routing, and ACL capabilities First end-to-end P4 integration test INT collector integration into Monitoring & Telemetry system A new P4 INT service handler Gradually into develop by the end of March 2024 Bug fixes (at least) 4 New features 6 Support for P4 5G UPF capabilities<br>
