Executive Summary

This report is written to describe the support given by the research network community to a user group with a challenging network application. This proved to be an important test case for the GÉANT2 Performance Enhancement Response Team (PERT) and for inter-working practices generally, between network domains.

Following a request from the VLBI centre, JIVE, DANTE instigated a series of measures to resolve data-transfer rate issues between TIGO (Chile) and JIVE (Netherlands). The effort was coordinated by DANTE and the GÉANT2 PERT and involved input from GÉANT2, RedCLARA, REUNA, SURFnet, TIGO and JIVE engineers. Despite very significant effort from all parties, the issue was not resolved by the date of the VLBI tracking of the SMART-1 spacecraft. This report outlines the direction of the investigation and the practical steps taken to diagnose and resolve performance issues.
