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>
