Agenda
4 main topics today: PROX, Internship status, Nile release, UNH Transition.
| Item | Desc | who | Notes/minutes |
Special Topic: Containerizing PROX | Luc, Sridhar, Trevor, and all | Update on Issue remains - haven't been able to collect the logs yet. Notes from Trouble finding the old logs: maybe in mail from Daniele SR - maybe give a presentation on AF_XDP https://github.com/intel/afxdp-plugins-for-kubernetes Cillium not working with DPDK - talking with Cillium group to sort this out - maybe needs telco requests. Also - Korea group is comfortable with Trex, that may be all Futurewei - has a solution for networking, but does it work with DPDK? https://github.com/CentaurusInfra/mizar SR is exploring teh solution and will connect if it makes sense. | |
Intern Update | Shivank | Notes on Third topo might be possible, maybe just use single CPU core, will plan to complete topo 1 and 2 for sure. Need status - Shivank was working on backups and installing Ubuntu, Notes from ACTION: Propose to Tim that we complete the Pod 12 work at end of January. Need time to transition to UNH AFTER the intern project is over. Status: Status Check from Shivank - needs to be completed Shivank has an exam today... Needs to take-over the work. First look at status - then we will review the Intern feedback form. Notes from Tim Gresham wants to know time horizon for the completion of the Intern project. Sridhar will try UNH - Sawyer or Lincoln Lavoie can get us started. Al sent mail with requirements IXIA was loaned to LF, intel just hosting it. Maybe it can be moved to UNH! need to investigate. Shivank: Status: Exams in progress. 3 tasks need to be completed. Where are we now?
Shivank's Internship page with progress: Internship 2022 - Benchmarking eBPF based solutions Internship 2022 - Benchmarking eBPF based solutions (pdf) If we can complete by end of the year - stay on Intel pod 12 Otherwise, Start to move to UNH LaaS | |
| UNH transition requirements | All | Notes on https://labs.lfnetworking.org/ demo Need to add Sridhar's SSH key -
Notes from SR's requirements: 1 Node for Jump Host (50% of the HW req below should be ok) 3 Nodes Kubernetes Cluster (1 Master and 2 Worker Nodes) Requirements on Each Single Node Configuration of the cluster 1. 1x Gigabit ethernet for control-plane/internet/external-access (management) 2. 2 to 4 x SR-IOV compatible NICs for dataplane (testing) At least 10GigE 3. 2 socket x (Intel Xeon E/Gold, (or ARM) at least 22 cores, at least 2.4 Ghz, approx 50mb Cache) 4. 64GB to 128Gb Memory 5. 180GB SSD and 3TB SATA HDD storage Networking between the nodes:
WHAT about COSTS? does TSC need to approve? No cost - NO Approval needed. ACTION Al Morton - fill-out request ASAP, then ping Lincoln and Sawyer on this. | |
| Discussion: Contribution on Containerized network benchmarking in BMWG session IETF-115 | Al |
Notes from Slides: Considerations for Benchmarking Network Performance in Containerized Infrastructure https://datatracker.ietf.org/doc/draft-dcn-bmwg-containerized-infra/ yangun@dcn.ssu.ac.kr Sirdhar will contact. mipearlska1307@dcn.ssu.ac.kr presented at IETF-115 | |
Nile Progress | all | Notes on Notes from Re-prioritize this for December, complete dev and updates... with possible shift to next release. Prioritize results for December! Review Sridhar Rao input Started Release Plan for ViNePerf Nile Sridhar has submitted 2 new patches, which will complete the dev schedule - Al must review. New SW versions and New OS versions. Adding Al as a reviewer. Using DPDK build with Meson and Ninja tools now. new tools. The build process is different for diff each OS now, diff folders for Fedora, etc. Need a discussion with Fulvio on the approach to use with building the CNIs. Sridhar will consider the questions to ask and try to exchange e-mail with Fulvio. Pod 12 is fine now! but we are the last user of the Intel community pods... The IXIA license has expired. Consider collaboration with Open Programmable Interface Project (Linux OPI) - need a member to join with us and start to identify common areas of interest. Sridhar will talk to Joe White, Dell TSC Chair. Node 3 in POD 13 has build issues - need to update that system. system dependencies. Build was successful in other locations, so we are interested to know where other projects are doing their builds. Maybe UNH Lab. | |
Sridhar presented at the Tech Discuss! | eBPF - final slides | ||
| eBPF topic (additional details) | Sridhar presented slides, which he used to familiarize Anuket with XDP and eBPF L3AF project in LFN - life cycle management on eBPF programs Cillium project has done some of their own benchmarking - but uses some unknown TCP: https://docs.cilium.io/en/stable/operations/performance/benchmark/ Not much uptake in telco - still many operations issues. The Cillium community agrees that they have not made a good case for telco usage (in conversations with Sridhar). | ||
| Shivank's Intern update - Archive: |
Here are Shivank's updates for this week.
Shivank's CPU not supported by DPDK . Need this for most of our benchmarking tools New T-rex traffic Gen have been added and a new DPDK folder. Sirdhar shared https://github.com/intel/afxdp-plugins-for-kubernetes it is a possible option to use Shivank will investigate. Mail to Casey Cain about Intern compensation and feedback. Shivank's report for last week: https://github.com/Alt-Shivam/eBPF-CNI Pod 18 connectivity not working for several days, impacting Shivank's work. Tim G says working... Need Pod 12 working as well. There is an active JIRA ticket and comment stream. Shivank testing with a VM and K8s cluster - can try out locally Need to review mid-term Mentoring report - Al and Sridhar completed in last half of the meeting. ACTION Al Morton invite Maryam meeting to discuss performance (when we agree it's the right time). | ||
Post review of Daniele's work closure to Daniele's work and see if there is anything worth publishing, may consider less-selective conferences if novelty is less | Sridhar | Some issues we dig into now No reply from simonartxavier@gmail.com and Luc? Al and Sridhar sent new messages. Once we containerize prox, and we assign multiple cores to single interface, it crashes. how can we run Prox with multiple cores in a container?? | |
| Tasks and Action Plan for Shivank (Archive) |
| ||
Open Programmable Interface Project (Linux OPI) Change CPU NIC architecture, more autonomy and CPU power goes to NIC in OPI, more than smart NIC now. New Trust boundary between Autonomous NIC and CPU. | Sridhar | New project, governing board formed and TSC meeting set. Opportunity for Benchmarking: work with us. Need to know planned NIC speeds, Need NIC HW to benchmark. There will be a test bed discussion, UNH and Keysight collaboration - using Keysight tools. We want to join the collaboration. Maybe UNH would welcome our help to some degree. Need some time to understand how the DUT HW will be obtained and installed. Also Remote access (for us, like Intel labs). | |
| Testbed - IXIA support | Sridhar/Al | 2nd ACTION: Do we have support from Ancuta or other IXIA person? Al Morton sent e-mail ACTION: License for IXIA HW - Check with Trevor Trevor Cooper says connected and powered on, but we still might have a license issue. Need Pierre's help. this activity seems to have stalled ... Pod 19 also not accessible - Dan Xu. ACTION: Al: can you add a comment in the Jira issue.. INFRA-7 ? As a PTL you can mention the dev is stuck with nodes being inaccessible. https://jira.anuket.io/browse/INFRA-7 | |
| Additional Mentoring input | Sridhar/Federica | Federica Past meeting: python scripts. Possible combine 1 and 3 @Sridhar will expand on the proposal descriptions and Federica will begin to ask students about their interests. python scripting with K8s is possible for some students in 3rd year. Projects must have resume value, add skill set or new experience. Sridhar Rao created some projects. ACTION: See proposals & review https://wiki.anuket.io/display/HOME/Potential+Projects+for+Student+Volunteers | |
| Intern (background info) | Sridhar/Al/Federica/Shivank | XDP performance Studies for Cloud-Native NFV Use Cases "Maryam Tahhan joins the crew to talk XDP, AF_XDP, and fast networking" Operations support seems to be a big issue, and performance is currently about 0.7 of VPP and DPDK | |
| K8s on Pod 12 | Sridhar | will look into it |
Progress for NILE Release
(summary: items 5,6,and 7 lack the necessary automated address discovery feature, defer)
see Nile Release Schedule Nile Release Progress page M4 currently due on Dec 9, M5 due on Dec 16
| 1 | Update OS versions | Tasks:
| Tasks 1 and 3 have been completed/merged. | |||
| 2 | Automate setting up eBPF-based CNIs - xdp, cilium, calico. | setup - xdp, cilium, calico. | ||||
| 3 | Improve the ViNePerf Build Stability | Starting from the build to the 3 environments
| ||||
| 4 | eBPF Metrics Collection | Task: Develop Tool to collect metrics from eBPF programs. | ||||
| Tasks below are deferred from Moselle - likely Defer Again because container networking support is poor and requires significant work-arounds. | ||||||
| 5 | Epic-VINEPERF-652:Enhance XTesting-ViNePerf Integration | Moved to Next Release | depends on 7 | |||
| 6 | Task-VINEPERF-658:Enhance framework for XTesting-K8s Usecase | Partially done (reading results from output), Deployment tool. | 1 task remains | |||
| 7 | Task-VINEPERF-654:XTesting-ViNePerf Integration Enhancement - Kubernetes | Will not implement due to limitations with CNIs. Moved to Next release - if CNIs support this. | Need CNI to add flows automatically in Switches (Userspace-CNI, supports DPDK, OVS, VPP). Major impediment to integrate with X-Testing Sridhar will check with Xavier if ARP resolution is supported in Prox as a switch TBD | |||
