RDMA for No-Compromises Remote Desktop Experiences

Sprache: English

When you think of remote desktop, you might think of slow corporate thin clients or the blockiness of game streaming with video compression. In this talk I share a proof of concept for fully uncompressed, low-latency, low-CPU-usage remote desktop using RDMA technology with you in the form of the Telescope Project / lgproxy.


Remote desktop typically compromises on framerate and/or image quality to achieve its goal of providing networked access to your PC. But what could we do on local networks if bandwidth was no object?

With RDMA, a hardware network offload technology, and a suitably fast network, we can achieve both. You get the low latency and high frame rate one expects from solutions designed for game streaming, combined with the pixel-perfect image quality, suitable for tasks such as video editing.

You don't have to leave the Ethernet ecosystem for custom cabling. It's also free and open source GPLv2 software in its early stages, and I look forward to any feedback.

Our project can be found at: https://github.com/telescope-proj/lgproxy
and its associated documentation at: https://telescope.timd.io

Telescope is made possible by building on top of great FOSS projects, namely the:
Looking Glass Project - https://github.com/gnif/LookingGlass
and Libfabric - https://github.com/ofiwg/libfabric

Systems Engineer; I spent more time than I would have liked to with niche HPC stuff.
