Wenting Wei, Xidian University, China |
Wenting Wei received the M.E. and PhD degree in Telecommunication and Information Systems from Xidian University, Xian, China, in 2014 and 2019, respectively. Since 2019, she has been working in the State key lab of ISN, Xidian University. At present, she is an associate professor in the School of Telecommunication Engineering, Xidian University (Xian, P. R. China). Her main research interests include data center networking, network virtualization cloud computing and intelligent networking. Speech Title: EPM-SR: efficient performance measurement framework for KPIs to support segment routing over IPv6 Network Segment Routing (SR) over IPv6 (SRv6 in short) is a promising solution to support advanced services, which is the instantiation of SR architecture for the IPv6 dataplane. The rapid development of the standardization and implementation for SRv6 is driving a critical need for accurate and scalable network performance measurement (PM) and monitoring techniques. There has been an emerging interest towards designing and enhancing PM for SRv6, however, it is still challenging to design a PM framework to produce accurate and real-time evaluation of key Performance Indicators (KPIs), while supporting software and hardware implementations of SRv6. In this paper, we provide an efficient PM solution for SRv6-enabled networks (termed as EPM-SR), considering both data plane and control plane aspects. EPM-SR provides accurate and real-time measurement of per-flow performance metrics, including packet delay, jitter and loss using two bits or less in the header of each packet. We have leveraged EPM-SR to validate the implementation of SRv6 behaviors in the Linux kernel and evaluate KPIs performance of the SRv6 implementation in both a simulation verification platform and a pressure testbed.
