 <\/p>\n

The P4 Workshop, the yearly event where the\u00a0P4 community<\/a>\u00a0gets together, usually at Stanford, to review a year of work, discuss future ideas, and in general discuss all things P4 was scheduled for this week. However, the COVID-19 pandemic got in the way, and as the date was approaching it became clear that such a large gathering of people would not be possible, even less would attendees from other areas be able to travel to California.
\nHence, a little more than three weeks ahead of the planned date, the Open Networking Foundation (ONF) took the somewhat brave decision to convert the event into a virtual one, which obviously implied changing the format of the event. And maybe to reinforce this, the name itself was changed to \u201cP4 Expert Roundtable Series<\/a>\u201d.<\/p>\n

Pros and cons of a virtual event<\/h1>\n

Although, of course, the networking aspect of the P4 Workshop is missing (the one among people, not the one related to devices\u2026), judging by the program, the content does not seem to be affected by the change of format.
\nOn the other hand, since each talk has been separately recorded, the tight timing constraints of back-to-back talks typical of live events are relaxed and speakers have a chance to provide as much information as they deem needed. Not only, but if something goes wrong in the presentation, it can be fixed, thus potentially improving not only the content, but also the quality of presentations.
\nOf course a Q&A discussion open to a wide audience is missing in the recorded sessions, but chairpersons have done a great job in making up for the lack of an audience by putting a particular effort in asking great questions. Moreover, the ONF organizers have come up with the good idea of structuring several of the presentations into panels, so that various presenters can discuss together and ask each other questions.<\/p>\n

Pensando contribution<\/h1>\n

Since\u00a0Pensando<\/a>\u00a0with its P4 programmable platform is being\u00a0very active in this space<\/a>, my colleagues and I are having a chance to experiment all three presentation formats that the virtual event offers.<\/p>\n

Our CTO,\u00a0Vipin Jain<\/a>, is giving a\u00a0live webinar<\/a>\u00a0on April 29, focusing on the motivation and benefits to extend P4 beyond packet processing to message processing, which is one of the areas that we are pioneering at Pensando with our P4-programmable\u00a0Distributed Services Card<\/a>.<\/p>\n

John Cruz and I participated in a roundtable on\u00a0P4 Use Cases for Programmable NICs<\/a>\u00a0where, deploying code excerpts from the implementation of a few services, we demonstrated the benefits of extending P4 and the PSA (Portable Switch Architecture) to account for the more articulated role of edge devices. This of course ties in the proposals we have made within the Architecture Working Group for the definition of a PNA (Portable NIC Architecture).
\nWe had a lively and interesting discussion with\u00a0Gordon Brebner<\/a>\u00a0who was moderating the panel and has been also involved since the beginning in the efforts around the definition of a PNA.<\/p>\n

Finally, I recorded a\u00a0talk<\/a>\u00a0within the \u201cAccepted Submissions\u201d track. It presented a work co-authored with my colleagues Diego Crupnicoff and\u00a0Silvano Gai<\/a>\u00a0(I\u2019d like to thank also\u00a0Sameer Kittur<\/a>,\u00a0Vijay Sampath<\/a>, and\u00a0Venkatesh Srinivasan<\/a>\u00a0for sharing the results of their performance measurements) that shows how a few real world use cases can be optimally and efficiently supported by the various components of the programmable data plane of Pensando\u2019s\u00a0Distributed Services Card<\/a>. Various performance measurements show that the considered services can be executed at wire speed, and exemplify how the versatile programmable data plane architecture1<\/a><\/sup>\u00a0offers developers various options to ensure top performance. All of this was further enriched by the following discussion sparked by the very interesting and relevant questions asked by\u00a0Mina Tahmasbi Arashloo<\/a>\u00a0who chaired the session.<\/p>\n

Lots of great content: don\u2019t miss it!<\/h1>\n

All in all, as much as I regret the missed opportunity of seeing in person the various folks of this tight knit community I have been interacting with over the past years and grabbing a beer during the traditional evening reception, the recording of my contributions and the interactions with the chairperson and other contributors were very positive experiences, both personally and from the point of view of effectively sharing the work done. The\u00a0program<\/a>\u00a0seems very promising and I am looking forward to watching the content that is made available. I highly recommend to register and get the videos.
\nThe one challenge will be to make sure to find the time for it among the various duties and conference calls we all have. Being locked in the conference room of the Arrillaga Alumni Center would have helped a lot in this respect. But let\u2019s not allow this to compromise such a great opportunity to learn and get inspired.<\/p>\n

And I am sure next year we\u2019ll see each other again in Stanford!<\/p>\n
