FABRIC Testbed Release 1.1

Release Date 02/28/2022

Major Changes

This is a major update to 1.0 capabilities. The enhancements include:

  • The portal includes a graphical slice viewer that helps you display your slices created e.g. in Jupyter Notebooks
  • Bastion hosts are fully integrated into the infrastructure including the Portal (and required to be used to access VMs)
  • Two brand new L3 network services – an IPv4 and IPv6, to which you can attach your VMs. Unlike on-demand L2 services available before (and in GENI), routing is automatically pre-configured within those and any VM attached to a L3 service at any site can communicate with any VM at any other site – these are are own two private Internets.
  • New FABlib user-facing Python library to help manage your experiment resources. FABlib is more intuitive and easier to use than FABRIC native low-level APIs and abstractions.
  • New VM images for different flavors of operating systems
  • Updated Jupyter Hub notebooks that integrate new enhancements and help you learn how to use them
