Hiro highlighted the GWG would only discuss and propose the RSS governance model, not the substance of requirements or performance assessments for the RSS and RSOs, such as technical features or an ideal number of RSOs. These issues would be handed over to newly structured organizations proposed by the GWG and community input. Open for public viewing, the GWG’s working sessions could be accessed from the RSS GWG page.
Proposed RSS Governance Model

In terms of DNS resolution performance, Baojun Liu (Tsinghua University), who joined the RSSAC Caucus in November 2020, shared a root server instance performance study in China that measured the network latency between Chinese Internet users and their queries with DNS root servers/instances. The study found that the geographic location of ISPs had a significant impact on the latency rate. For example, the installation of an F-root instance at China Telecom reduced the latency rate for its own users but had little impact on improving the latency for China Unicom users. Hence, latency optimization was unbalanced and further performance monitoring and assessment was needed (Baojun’s slides are included in the “Appendix” of the session’s presentation deck).
Che-Hoo Cheng (APNIC) asked what an ideal percentage would be for root server instances in APAC. Anupam responded that there could be different models to look at it, and the India Internet Foundation is working on one which considers the number of Internet users served per root server instance. Ideally, the resulting average should be similar across all regions, and based on a quick estimate the target could be approximately 40-45% for APAC. Hiro shared that a RSSAC Caucus Work Party is currently developing a tool to gather local perspectives of the RSS, such as identifying underserved regions in terms of number of instances, but also performance measurement and monitoring.
