HDX

The protocol that makes the difference: a smooth experience even on difficult networks — video, peripherals and 3D included.

01 · What it is

HDX, made clear.

VDI is decided on the experience, and the experience is HDX: the adaptive transport (EDT) that makes even the train's network smooth, the Teams and video offload (the call runs on the client, not in the data center), the 3D support for CAD, and the peripherals — printers, signature pads, scanners — that work like local.

Policies per population

The CAD designer and the data operator have opposite needs: HDX policies per group, not one-size-fits-all.

Multimedia with judgment

Teams/browser offload where it fits, transcoding where needed: the bandwidth well spent.

Mapped peripherals

Printing, graphometric signature, scanners: the special cases tested before the rollout.

Measured, not perceived

Session latency and ICE RTT in the reports: the experience with numbers (uberAgent helps).

03 · In depth

The protocol: adaptive, multimedia, frugal

HDX is the experience's engine: the adaptive transport (EDT over UDP with TCP fallback) keeps the session smooth even on bad networks, the adaptive throughput doses the bandwidth, the codecs (H.264/H.265/AV1 selective per region) balance quality and CPU, the multimedia offload (Teams/Zoom optimization) takes the audio/video out of the datacenter, the session watermark and the clipboard/drive mapping policies govern the channel's security.

  • EDT — the UDP transport that forgives the network: the branch on 4G works
  • Codec adattivi — H.265/AV1 where needed, lossless text where it counts: quality and bandwidth together
  • Teams optimization — the AV peer-to-peer from the client: the datacenter doesn't play switchboard
  • 3D Pro — the vGPUs for CAD: the remote graphics workstation
  • Policy di canale — clipboard, USB, drives: every flow governed by policy
  • Session reliability — the session that survives the network holes: it reattaches by itself

The user experience is tuning: HDX policies, codecs and QoS tuned by us — the VDI you don't feel.
05 · Use cases

Where it really pays off.

Serious remote working

The full office even from the home network.

Remote CAD & graphics

The workstation in the data center, the designer anywhere.

Difficult networks

Construction sites, ships, foreign branches: HDX holds.

If the user feels the distance, the VDI has failed: well-tuned HDX isn't felt — that's our trade.
