FABRIC Testbed Release 1.2

Release Date 05/28/2022

Major Changes

This is a major update to 1.1 capabilities. The enhancements include:

  • The portal includes a graphical slice builder that allows experimenters to graphically define their experiment slice topology. This is in addition to the already available graphical slice viewer.
  • Two brand new network capabilities:
    • Facility Ports – allow to attach FABRIC experiment slices to external facilities. The first facility to become available is Chameleon UC site, other sites (Chameleon TACC, CloudLab Utah) soon to follow.
    • Mirror Ports – allow experimenters to mirror traffic from the dataplane into their slice on demand.
  • Per-project authorization – starting with this release FABRIC software will enforce per-project permissions on what types of FABRIC features members of the project are allowed to use. A basic project allows to create small VMs with shared NICs and only within a single site. All other features – NVMe, SmartNICs, GPUs, larger VMs, advanced network services, specific Facility Ports must be explicitly allowed by requesting that FABRIC operators add authorization tags to the project.
  • Multiple enhancements for supporting experiment configuration – post-boot scripts, interface configuration.
  • Enhancements to FABlib to support new features in the Control Framework
  • Updated Jupyter Hub notebooks that integrate new enhancements and help you learn how to use them
