| Regarding to your study results, the Cloud-native model using SR-IOV and CPU-pinning achieved 70.000 TPS, 1.5 times the TPS obtained by the bare-metal model without CPU-pinning. The proposed SR-IOV and CPU-pinning seems can support 5G core network in varied applications. Could you please describe how to implement real applications in the setting of SR-IOV and CPU-pinning? |
Thanks for your interest but I'm really sorry. Because the installation and configuration of applications to use SR-IOV and CPU-Pinning are very complex, I cannot describe them by a few sentences. If you really care, you can exchange with me via email. |

| 2.The stidy implemented the CHF with four different network models for evaluating resource usage and system performance among different network models. The major evaluation indexes are CPU consumption, TPS, and latency.
Is it possible to integrate these 3-dimensions (ie., CPU consumption, TPS, and latency) into a single measurement for remonstrating the cost-performance ratio for comparing and selecting the best solution among the alternatives? |
I think it's impossible because we consider other criteria depending on different cases. For example, in 5G, TPS and latency are two factors that play a more important role than CPU consumption. However, low power is more important criteria in IoT devices

| First of all, thank you for the good research paper and presentation contents. I would like to know more about the research environment used in this study, and also in detail about the equipment & operating systems, development languages and software libraries you used. |
Thank you for your question. The environment that we conduct research includes three physical nodes with Intel 8260, which have ninety-six 2.4GHz threads and 256GB RAM. The Kubernetes version was 1.18, and the Aerospike version was 4.13 in all deployments. All run on RHEL 7.9 environment. CHF is written in Java language. |

| Will you tell us what is the major achievement of this paper, and also what is further study issue from this? Thanks in advance!! |
Our test result has demonstrated that the model using SR-IOV and CPU-pinning outperformed the bare-metal model with CPU-pinning by 30%, in terms of network throughput and package processing. In the future, we will continue to integrate with DPDK and look into the optimal disk I/O for Kubernetes with high IOPS applications. |

| Dear Author, you have a very good research. I would like to know if the technology today is capable of implementing your proposed scheme? Is there an existing technology almost similar to your proposal that has been deployed in real world environment? Thank you and stay safe. |
Currently, we are using a real-time cost calculator called Viettel Online Charging System, or vOCS for short, to track telecommunication service usage. The next version in 2022, vOCS 4.0 for 5G, will apply this scheme. |

| Dear Author, you have a very good research. What would you expect to have improvement when you employ DPDK in your solution? |
Thank you for your question. We hope that when integrating with DPDK, our system will achieve better results, which can be about TPS, latency or resource consumption. |
