2022-11-30 Agenda and Minutes

Special Topic: Containerizing PROX  16 Nov 2022 

Update on 30 Nov 2022 

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.

Notes from 23 Nov 2022 

Sridhar tested - same issue

within container, start prox, many screen feedbacks - log file has been stored and shared. -Luc will look at this.

Need to check DPDK, there may be something broken in DPDK? 

Luc will look at log file and nail down driver files, vswitch, maybe try testPMD instead of prox  on the same container? - Sridhar will test this. If works, how many cores are used? -they are equally divided across the interfaces.

Intern Update  16 Nov 2022 

Update30 Nov 2022 

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 from23 Nov 2022 

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 sends mail with requirements eventually....

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?

1. Infrastructure setup: Install
   1. OS
   2. Software
   3. cloud, K8s
2. Test Setup (DUT, Testing tools)
   1. vswitch- kernel module - switching solution
   2. CNIs
   3. TGen Pods
   4. Forwarding Pods
3. Test Runs
   1. Run Tests
   2. Modify 2 and repeat.

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

Notes from 02 Nov 2022 

Tasks assigned are complete except  —

need to change pod manifest files

test setup with node 5, trex is not generating traffic

Is cluster up? no  do cleanup and do fresh installation -

Ansible scripts are failing at the same stage.  Need a call sometime and try to fix it together.  k8sclustermanagement.yaml is not working. call scheduled to fix.

Can we think of replacing CENTOS with Ubuntu? Yes we should do - CENTOS is very old...got to Ubuntu 22.04 LTS Server Edition.  Take a backup and re-install.

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:

1. need separate management network and dataplane/testing network
2. What does the dataplane network include?  ToR switch? How many hosts share the ToR switch?
3. VLAN tags needed?  How many?
4. Direct cabling between NICs of Master and one worker nodes would be ideal.

WHAT about COSTS?  does TSC need to approve?

ACTION Al Morton  - fill-out request ASAP, then ping Lincoln and Sawyer on this.

Nile Progress

Schedule

Notes on 30 Nov 2022 

Re-prioritize this for December, complete dev and updates... with possible shift to next release. Prioritize results for December!

Review Sridhar Rao input 02 Nov 2022 

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.

 12 Oct 2022  Sridhar presented at the Tech Discuss!

eBPF  - final slides

Sridhar Rao 

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).

19 Oct 2022 

Here are Shivank's updates for this week.
https://wiki.anuket.io/display/HOME/Internship+2022+-+Benchmarking+eBPF+based+solutions
repo:
https://github.com/Alt-Shivam/Benchmarking-eBPF-XDP
Sridhar Rao commented: target to complete the Topology-1 (refer to slides that I had sent) first as baseline results to compare with previous results.

21 Sept 2022 

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:  14 Sept 2022 

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 13 Jul 2022 

closure to Daniele's work and see if there is anything worth publishing, may consider less-selective conferences if novelty is less

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.

20 Jul 2022 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).

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.

11 May 2022 this activity seems to have stalled ...

13 Jul 2022  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

"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

CCLA for Moselle release (LF as C)

CCLA issue resolved 27 Apr 2022 

Patch is submitted - Done.

Danielle will submit patches after Thesis on Friday, Monday  04/25

27 Apr 2022 After review tomorrow, Daniele will submit the patch.

Al Morton will need to review (big patch with documentation) - Done 11 May 2022
