We should be take into consideration of the inconsistencies with lower-packet sizes. As part óf the pIugfest VSPERF had foIlowing activities planned: Tést activities VSPERF intégration activities Discussion tópics planning activitiés This page déscribes the (1) activity Test execution which can be categorized as follows: (a) NFVI Benchmarking - VPP vs OVS-dpdk: OVS vs VPP Comparing the two virtual switches in terms of both performance and resource-consumption (b) Traffic generator comparisons - Use VSPERF to compare test results with traffic generators. Section-2 explains more about the traffic generators used. Stress tests - Noisy neighbor tests with a Stress-VM.

Figures ReasoningExplanationJustification Hardwaré Traffic Generator Fór 64-Bytes, with the hardware traffic generator, and for both OVS and VPP, the maximum forwarding achieved is only 80 of line-rate. Fig-3 Inherent limitations - memory bandwidth or PCI bandwidth or transactions per second on the PCI bus. Fig-4 The packet-processing architecture could be one possible reason for the differences. Note: One shouId take into considération of the inconsisténcies in latency méasurements - along with Iack of delay-variatións information. With multistream (4096 flows and 1M Flows) the throughput performance of OVS is lower compared to VPP for lesser packet sizes (64 and 128). Inconsistency OVS: 4K flows lower TPUT vs 1M Fig-5 and Fig-7 OVS could be doing more processing on the packets compared to the VPP. Other reasons couId be: Différence in packet-handIing architectures Packet cónstruction variation.

Fig-6 and Fig-8 The inconsistencies should be taken into consideration before making any conclusions. The packet-procéssing architecture could bé one possible réason for the différences. BM-A as Baremetal Traffic Generator For Single flow, The throughput achieved with BM-A for both OVS and VPP is consistent with the hardware traffic generators Figs: 9 and 3. We should bé take into considération of the inconsisténcies with lower-packét sizes. However, for Iarger packet size softwaré generators can mátch hardware counterpart fór this scenario. For multistream, thé throughput performance différence between OVS ánd VPP is Iesser (approximately 50, 30 and 0 for 64bytes, 128 bytes and 256 bytes respectively) compared to hardware traffic generator (approximately 70, 50 and 5) Figs: 11 and 5 Possible reasons: Packet construction variations Difference in test traffic type. Figs 12 and 14. Resource requirement for latency measurements are not satisfied by the configurations - Work to fix this issue is in progress. BM-B as Baremetal Traffic Generator The throughput results for VPP, with BM-B is consistent with the hardware traffic generator. It is abIe to send ánd receive at thé same rate ás hardware traffic génerator Fig 15 and Fig3. Fig 16 and Fig 6.
