Agenda
main topics today: UNH IOT Transition. Other possibilities:
| Item | Desc | who | Notes/minutes |
| UNH transition | All | Sridhar Rao hpe32 with OVS with XDP looking to use two more interfaces - for IXIA server or other servers back-to-back. Otherwise must use the VLAN Can we connect ens1f0 and ens1f1 to IXIA, or other hosts. or connect to New VLAN through a switch. Don't want to use the VPN interface for testing, of course. (interface ens1f0 on hpe25) There are a total of 6 interfaces. REQUEST: Directly connect two interfaces on hpe32 and hpe25 Node 4 Node 3 hpe32 hpe25 ens1f0 ens4f0 ens1f1 ens4f1 If direct connect not possible - configure through switch for connectivity. ACTION - contact UNH team for this question. Notes from Sridhar working on a bug with the deployment of eBPF-based solutions, intending to benchmark the OVS and VPP, North Bound userspace CNI. May need special network connectivity to restore our Node back2back capability (from Intel lab) Sridhar will contact Fulvio Risso in Italy for possible chat and maybe some collaboration - just want to learn from his experiences. Have began to move IXIA generator to UNH, for connection there to the pod we are using. Notes of Sridhar has started setup in the new testbed. Seems stable and going well. VPN is good stability. Need a few more days to get going (all the basic stuff needs to be setup.) Completing install of PROX and Trex. eBPF support varies from OS to OS: Different form Ubuntu 20.04 to 20.04 - strange - trying to create superset of library of eBPF support and deployment. Needed kernel rebuild in one system, but not in another - so need to re-build to to be safe or check in the kernel. All the details must be known so that the automation works. Sawyer Bergeron says that the booking has been extended to late May, 2023. | |
| CN Perf Verification | Trevor and Luc | Market in Edge-cloud Infra..structure. For smallish Companies who need to make decisions on their deployments, but don't have the people or expertise to do the work in a timely way. Sridhar - Are you in an SI – What is this? has established suppliers and a complete framework. Sridhar - HW gives SW compatibility only, visa-versa, but do not guarantee specific performance. They begin and end with their Compatibility Lists, but in reality this is not enough! They may never get the performance they are promised, then finger-pointing between CNF and HW vendors. There is an enormous amount of stuff to configure. acm - TCO is the most important aspect of this proposal - modeling is hard, cores/resources can be stranded. Networking costs can be really high - swamping the rest of costs! Sridhar - work-out what the follow-up would be, every time the HW or SW changes (frequent event). Training can be a part of the solution - but only if the customer will build or have access to a lab. Sridhar - Artifacts should include the golden configurations. Sridhar - Also provide Root-Cause Analysis - benchmarking with bottlenecks identified. acm - power benchmarking - see https://datatracker.ietf.org/doc/html/draft-manral-bmwg-power-usage-04 Sridhar - apart from solving today's problems, additional HW adds complexity and performance improvements - can ID ability to solve the next generation of problems (DPUs and beyond). Sridhar - How are Tier 1 Operators doing this? A Major question = Obsession with Tier 2 and lower. | |
| Student Volunteers | Federica | Notes from No news on Student Candidates. (from student forum) It would be to know the school deadline. - It is the entire Semester. ViNePerf will not do an LFN internship this year. | |
| Deepdive on eBPF XDP AF_XDP | Sridhar | Note from First step is to verify that a single L2 forwarder will work (Cillium's ability to use DPDK is in question) | |
| Discussion: Contribution on Containerized network benchmarking in BMWG session IETF-115 | All | ||
| UNH transition | All | Given that our Pod terminated (time-out) is there any way to recover? Or better to start from scratch? Can automate the IP addrs assignments for all the traffic links - How? Can Config.YAML really work? or is Ansible better? | |
| Testbed - IXIA support | Sridhar/Al | Tim Gresham asks for resolution on this. If we can get it, do we want it? No good without license! So, is a license still valid or available for update? THEN - need to ship and install in UNH, get working there - IXIA help to do this.
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. |
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, 3, and 4have been completed/merged. Not doing 2. DONE | |||
| 2 | Automate setting up eBPF-based CNIs - xdp, cilium, calico. | setup - xdp, cilium, calico. | Patch submitted patch, will request review. | |||
| 3 | Improve the ViNePerf Build Stability | Starting from the build to the 3 environments
| Testing in-progress: either run in OS or K8s - 2 and 3 are challenging and 3 is the priority. | |||
| 4 | eBPF Metrics Collection | Task: Develop Tool to collect metrics from eBPF programs. | Existing tool, just running it with a script Skywalking from Apache skywalking-rover possible eBPF plugin in collectd - propose for barometer or KDDI - | |||
| 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 | |||
