DASH Community Upcoming Project Action Items
Discuss:
The Community looks to be moving through the testing maturity stages (as we had originally planned).
If any contributor would like to publicly show their DASH progress (DPU, IPU, EPU, Switch, other…), or even focus on SONiC, the DASH API, or show that it simply 'works' to the Community, please feel free to reach out to Keysight and/or let me know. A demonstration
would focus on the functionality of the system (rather than performance).
Discussed a description/configuration issue related to inbound in
Issue452 and requested an update from the SONiC team; PR was created to update the document (thanks @Riff)!
Kristina and Chris discussed the P4 behavioral model and its enhancements. Chris mentioned that his colleague (Meyappan) is interested in contributing more to the P4 behavior model.
Mentioned DHCP IP address assignment for the DPU in the next Smart Switch meeting.
Kristina also mentioned that Amith is working on PR436 and 415 and Meyappan will connect with him. Kamil was added to the project.
Amith was working on PR436 and 415. Meyappan confirmed that he was in touch with Amith and would take a look at the issues with him.
Riff Jiang will send out invites to the group for the Linux Foundation meeting.

|
PNA consortium spec |
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. |

|
IPDK |
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 |
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 |
DPDK is the Data Plane Development Kit which consists of libraries to accelerate packet processing workloads running on a wide variety of CPU architectures. |
