What does this new year mean for ViNePerf? | All | Sridhar Rao Focus on completing the benchmarking activity (former Intern project)
Where are we now, regarding the eBPF and XDP and AF_XDP (similar to SR-IOV) has CNI and Device Driver plug-in:
Al Morton Many blocking issues with Intern, did not get to the more interesting benchmarking work. No Orinoco Release - focus on the benchmarking instead. @Federica might propose a student project, but need to understand the next steps first. There are updates needed to the student project proposals from last year. We will not participate in the LF Intern program this year. | |
Discussion: Contribution on Containerized network benchmarking in BMWG session IETF-115 | All | Invite Minh-Ngoc Tran to a future meeting, to check if our comments were adopted. Review with Minh-Ngoc Tran Draft: https://www.ietf.org/archive/id/draft-dcn-bmwg-containerized-infra-09.html 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 Sridhar Rao Tested many similar scenarios - performance difference among with VM and without VM is negligible. Not really necessary to test. Minh needs to check this with colleagues Sridhar will share our teams results - part of Daniele's work. The reason people run VMs is for security reasons and resource isolation -WHEN Containers did not supply. Parameters section: Cannot use a CNI independent of the Networking model (SRIOV or user space determines this) Some Networking models listed are not relevant when performance is the priority. Are these even applicable when performance matters? maybe not. For example, their networking model includes Kernel space switching will perform poorly. Minh replies that ALL the Models are included. Need to categorize into good/bad perf. Minh agrees. Performance Impacts: Major example is Number of Cores, which is not included in the Draft. Please add this. Minh agrees. Section 3 clarify the use of Containers and Pods - used interchangeably now. need to clarify Section 3 Some generalizations about CNI are not correct - Some CNI do not use user namespace Figure 1 What is Container Engine? is it Container Run-time. 4.2 Some duplication on Container Network Plugin? Agree. Can use different CNI with same network Model - no difference. The SR-IOV networking model would make a big difference with other models, but CNI not so much. The Vswitch and the Networking model are closely tied together (Models with VPP are not possible with OVS, for example). Section 4.3 CNI does not create it's own switch functions Also, which of 5 networking models does Calico fall. Figures in Section 4.3. Normal Calico does not use eBPF Calico should fall in section 4.3.1 figure, but needs to be fixed. (remove "VSwitch") and add Kernel routing tables in the user space vswitch block. There was a Cillium eBPF scenario that was in the slides - this is not possible with the traffic gen and DPDK. | |
Intern Update | Shivank |
has connectivity working - should be finished by tomorrow. author of eBPF bridge says has same problem. Need to use Ansible for automation-this is key. There were some version issues, need older version? Plan is to Finish-up by Friday . We hope it will go well for you! | |
Nile | Need to update with changes in December (12/2 for stable/nile was too early). | ||
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. |
