We deployed the new M-Lab platform to 1/3rd of the M-Lab fleet, and now we need to assess whether or not it is a performance regression, relative to the old platform. As long as we can be sure the performance of the new platform does not constitute a regression, then we can roll out the new platform and be confident that we have not made anything worse.
- Stock Linux 4.19 LTS kernels with modern TCP and Cubic congestion control
- Standard instrumentation for all experiments using tcp-info
- Virtualization and container management using Kubernetes and Docker
- Reimplementation of the NDT server
Last year, we outlined our plans to Modernize the M-Lab Platform. This year, we’re bringing them to life. Here’s a summary of why the platform update is so valuable and what you can expect throughout the year.
When the M-Lab platform was initially launched in 2009, the software and operating system running on our servers used the best available boot management, virtualization, and kernel-level measurement instrumentation available. In the years since M-Lab’s initial launch, the state of system administration has improved dramatically. In 2017, the M-Lab team began work to upgrade the platform to adopt modern and flexible system administration components. This post provides a roadmap of that work.
