TSSG PhD student Runxin Wang recently attended the RIPE66 meeting in Dublin. This conference was hosted by RIPE NCC (Réseaux IP Européens Network Coordination Centre), which is an independent, not-for-profit membership organization that supports the infrastructure of the Internet through technical coordination in its service region. RIPE NCC is one of five Regional Internet Registries providing Internet resource allocations, registration services and coordination activities that support the operation of the Internet globally. The 66th RIPE meeting (RIPE66) in was well supported by many major IT companies and network operators including Google, Amazon, Netflix, and HEAnet. Presentations at the meeting covered the recent developments, experiences, statistics and new ideas about the management of bandwidth usage, IP usage, routing technologies, DNS security and other topics of global networking from different countries. This year RIPE launched a new program RACI (RIPE Academic Cooperation Initiative) to bring in more students from academia to share their research work to the RIPE community; Runxin was one of the five invited students in the RACI program.
