Session Abstract

Research and education (R&E) networks provide a critical circulatory system for research data. As such networks enable researchers to transfer and share large datasets, making national and international collaborations possible. It is becoming more common for research institutions and instruments to be physically separated from the data storage and computing facilities, along with the users that intend to consume the data. Thus the network connections provided by the research networks are crucial in delivering results for researchers from end-to-end but these resources can be complex and multi-domain in nature. Often times researchers need help and expertise from engineers to use these resources efficiently, if not it could hamper them, in for instance their (inter-)national collaboration with other researchers.

Many network engineers and operators have acquired knowledge and experience with troubleshooting and solving problems in these multi-domain systems, leading to some network organizations to have designated teams. These teams are sometimes referred to as Scientific Engagement teams or PERTs (Performance Enhancement & Response Teams), who are devoted to solving network performance problems and setting network performance expectations for collaborations or institutions using the network. These teams not only work with each other, but they also work with the institutions to identify issues on backbone networks and at "the last mile” (such as research institutions, university campuses, etc), which often involves tuning servers or software, and developing solutions for special use-cases.

It is infeasible to solve an end-to-end networking problem by only focusing within a single organization or domain. However, to fully address the needs of researchers, many of which are not network savvy, the R&E network community must work closely with operational staff for each piece of the research workflow; the researcher, the local ICT departments/network engineers, data transfer specialists, regional/national network engineers.

This panel will discuss how multiple NRENs approach solving these complex problems and what future efforts look like in network performance enhancements.
