    At Sciebo we migrated the first half of our productive ownCloud instances, serving over 200k customers across the state of North Rhine Westphalia at universitary institutions, to our new on-premise kubernetes platform.
    Last year we presented an overview of the rough architecture of the platform and promised some more insights for this year's CS3. ;-)

    CERNBox is key enabler service for users at CERN and beyond. The service is used by more than 37K users and stores over 15PB of data, representing all the user communities at the laboratory.

    In this talk we will explain the current status of the service, the challenges we faced in 2021 and we look into the future: CERNBox as the gateway for heterogeneous storage spaces at CERN and beyond.

    Sunet is currently establishing Sunet Drive as their solution to store and share large amounts of scientific data. The architecture is based on a global scale setup of Nextcloud, where each university and college gets an own node, which then can be customized. The underlying storage infrastructure is based on S3 containers, and each university can manage and assign new buckets depending on...

    Since a few years SURF has been running a sync-and-share service called Research Drive next to the personal storage based SURFdrive. Research Drive is specially tailored for the special needs of researchers. These special needs had to do with flexible quota, project-based storage rather than personal storage and multiple means of authentication. The latter was an absolute necessity in order to...

    Last year, we had a first version of the OCM test suite, testing three flows of OCM v1.0 between Nextcloud, ownCloud, and a stub server. These tests were running between a number of live test instances, deployed to virtual private servers for this purpose.

    This year, we present:
    * the Dockerized version of these same tests
    * the addition of Reva/IOP as an OCM v1.0 implementation

    The Invitation workflow is one of the elementary scenario on how to enable file sharing among users from different EFSS systems. Invitation workflow eliminates the necessity of knowing the exact identity of the user (share receiver) in the target EFSS system. You can generate a share invitation and distribute it via email or distribute the link via any other channel, chat app, etc. The target...

    In the OCM specification the share message specifies the protocol to be used for establishing the synchronization. For regular shares the webdav protocol is supported.
    We present a (custom) protocol 'datatx' to support data transfer in the mesh. Using this protocol signifies that the share message is in fact a data transfer.
    This presentation will be about this new OCM protocol extension...

    Existing implementations of OCM generally implement the public-link workflow and the share-with workflow.
    Reva implements the share-with workflow and the invitation workflow.
    Should other OCM implementations add this third workflow too?
    Should Reva add the public-link workflow?
    Can we keep OCM-over-ScienceMesh and generic OCM-over-WWW in lock-step?

    OCM assumes the sender of a share is a specific user.
    But in some situations it would be useful to think of
    shares as owned by a group. Would this be a feature
    we could add to OCM? What would be needed? What issues
    can we foresee?

    Imagining a new Internet architecture enables us to explore new networking concepts without the constraints imposed by the current infrastructure. What are the benefits of a multi-path inter-domain routing protocol that finds dozens of paths? What about a data plane without inter-domain forwarding tables on border routers? What secure systems can we build if a router can derive a symmetric key...

To best support the individual existing definitions we designed and implemented a system which is open enough to be fitted to the environment. oCIS extensions will also benefit from that, because they can use this system for their permissions instead of...

    When working on the spaces feature we reorganized reva's internal path semantics.
