GridFTP transfers and the corresponding Grid Security Infrastructure
(GSI)-based authentication and authorization system have been data transfer
pillars of the Worldwide LHC Computing Grid (WLCG) for more than a
decade. However, in 2017, the end of support for the Globus Toolkit - the reference
platform for these technologies - was announced. This has reinvigorated
and expanded efforts to replace these pillars. We present an end-to-end alternate
utilizing HTTP-based WebDAV as the transfer protocol, and bearer tokens for
distributed authorization.
This alternate ecosystem, integrating significant pre-existing work and ideas in
the area, adheres to common industry standards to the fullest extent possible,
with minimal agreed-upon extensions or common interpretations of the core
protocols. The bearer token approach allows resource providers to delegate authorization
decisions to the LHC experiments for experiment-dedicated storage
areas.
This demonstration touches the entirety of the stack - from multiple storage
element implementations to FTS3 to the Rucio data management system. We
show how the traditional production and user workflows can be reworked utilizing
bearer tokens, eliminating the need for GSI proxy certificates for storage
interactions.
