DASH Workgroup Meeting Minutes 7/27/2022

[Kristina Moore]

Hello DASH Community – we were treated to a great demo from Keysight on Wednesday; if you missed it and would like to view - please use the YouTube or Teams link below in the ‘sticky notes’ section to watch.  The notes follow below, along with the recording links. 
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). 

Takeaways from this week:  as @Chris Sommers noted, we do need more APIs in the libsai directory in jinja templates under C++ code.  And let’s consider a Workshop to go through/try Chris' demo.

 

See you on 8/03/2022

Progress report:

 

 

 

The container below has everything we need to run tests w/o contaminating the client
Q: Are snappi and scapy competing?
A: Scapy is great for 'packet at a time test'. Snappi is great for running tests that have flows and scale.  Complimentary paradigms, we can support both.

 

 

 

Quick Start Guide:

Q: How to run on real hardware w/o P4 runtime?
A: This would below be your hardware (replace)
 

 

Snip/example of (C++, py, and PTF) tests running:

 

 

 

 

Client libraries and interfaces above (arrows)

 

 

Q: Mircea - Behavioral Model meeting question about VNET routing use cases. 
A: Marian - VNET routing test can be run; what we don't have is stateful ACL.

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.
