DASH Workgroup Meeting Minutes 8/10/2022

[Kristina Moore]

Hello DASH Community – On Wednesday, Keysight presented progress re: the DASH Hero Test Config Generator and a Baby Hero Test update (see PRs below for review and to make comments). Thank you so much @Mircea Dan Gheorghe and team for the hard work!  The relevant notes are below along with the recording links: 

If anyone has Agenda items for next week, please reach out to me.  Some ideas could be:   
-Now that SAI Thrift test work is being done (and demos) could we start w/early implementations of SAI Thrift on hardware (Stage 3 of Test Maturity Model)?
-Images and documentation for SAI?

If you have a chance, please subscribe to the DASH YouTube channel to access Weekly and WG content (and click the bell to receive notifications). 

See you on 8/17/2022

Keysight/Mircea presentation:

https://github.com/Azure/DASH/pull/182 - DASH Hero Test Config Generator
https://github.com/Azure/DASH/pull/188 - Baby Hero Update
 

o   Keysight will expand different methods to expand generators (ways of configuring) while keeping the logic the same, as we move along

o   Variable file drives the scale; example shows a reduced and a large sized config

o   Eventually we’ll use generators to drive Sai interfaces instead of just producing files

o   JSON format is provisional and can be modified to match official SONiC schema as it becomes stable

o   Technology providers can adapt to their own use-case and proprietary config formats

o   Policy and Route Requirements

o   Scale

o   Discuss Keepalive in CPS test

o   We need observability of flow table states/fullness. If we need some fixed SAI APIs we should start defining them

o   Feel free to contribute improvements/use-cases

SAI Thrift	SAI Thrift PR	Client server needed for testing
P4	https://opennetworking.org/p4/ and https://p4.org/working-groups/	Open source, domain-specific programming language for network devices, specifying packet processing for data plane devices (switches, routers, NICs, filters, etc.)
PINS	https://opennetworking.org/pins/
PNA consortium spec	https://p4.org/p4-spec/docs/PNA-v0.5.0.html	An architecture describing the structure and common capabilities of network interface controller (NIC) devices which process packets transiting one or more interfaces and a host system. Describes the structure and capabilities of the pipeline, and a user program, which specifies the functionality of the programmable blocks within that pipeline. For more information, see the P4 Language Consortium specifications
IPDK	Infrastructure Programmer Development Kit (ipdk.io) and https://github.com/ipdk-io/ipdk-io.github.io	IPDK is an open source, vendor agnostic framework of drivers and APIs for infrastructure offload and management which runs on a CPU, IPU, DPU or switch. IPDK runs in Linux and uses a set of well-established tools such as DPDK and P4 to enable network virtualization.
bmv2	https://github.com/p4lang/behavioral-model	The second version of the reference P4 software switch, nicknamed bmv2 (for behavioral model version 2). The software switch is written in C++11. It takes as input a JSON file generated from your P4 program by a P4 compiler and interprets it to implement the packet-processing behavior specified by that P4 program
DPDK	https://www.dpdk.org/	DPDK is the Data Plane Development Kit which consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures.

Thank you again for your participation…
